Read before operation

Important safety precautions

Only trained operators who have read this page, the material SDS and the facility batch procedure may use the kettle.
Wear protective clothing, gloves and eye/face protection rated for the material and process temperature. Use footwear and an apron that protect against a hot spill.
Install the complete frame on a stable, level, noncombustible floor that supports the full operating weight. The source manual specifies at least 20 feet from combustible materials.
Position the kettle while it is empty and cool. Lock every caster before seating the pot, loading, heating, mixing or tilting. Never roll the unit while loaded or hot.
Keep everyone out of the tilt arc, discharge path, splash zone, under-pot area and all pivot, frame and caster pinch/crush points.
Use only materials approved for the exact pot, outlet, valve, gasket/seal, mixer and temperature range. Review flash point, decomposition temperature and incompatibilities before heating.
Use a correctly rated, grounded, dedicated electrical supply. Do not use an extension cord, power strip, timer or overloaded shared circuit.
Do not energize the pot empty, with too little material, unattended, unseated or while a connector is loose.
Do not connect/disconnect the pot connector, remove the pot, work on the frame or service any part while energized or hot.
Never use a torch, heat gun, open flame or unapproved heater on the pot, valve or outlet.
Keep the controller, circuit protector, cords, plug and pot connector clean, dry and protected from drips.
Stop and secure the optional mixer before removing its lid/mount or tilting the pot. Never allow the shaft or blade to contact the pot.
Do not exceed the rated fill, alter the center of gravity, extend the tilt handle or force the pot beyond its designed travel.
Allow the pot, contents and frame to reach a safe condition before cleaning, removal or service.

Tilting changes the center of gravity and creates a moving hot load. The receiving vessel must be compatible, stable, correctly sized and positioned before the kettle moves. Do not try to catch, steady or redirect a moving pot or hot stream by hand.

Initial setup

Assembly and setup

Choose a safe location. Use a stable, level, noncombustible floor with operating clearance, ventilation and an unobstructed discharge and emergency path.
Position the empty, cool frame. Do not move the system by its pot, cord, control box, valve or mixer. Lock every caster and verify the frame cannot roll, rock or tip.
Keep every component de-energized. The pot, controller and mixer must be cool, empty, switched off and unplugged during assembly.
Inspect the frame. Check the cradle, pivot, tilt handle, travel stops/retainers, welds and caster locks. Do not load a bent, loose, cracked or unstable frame.
Seat the removable pot fully. Lower it into the intended supports without pinching fingers, cords or tubing. Confirm it is centered and captured by the original stops/retainers.
Install the ball valve if equipped. Preserve the factory gasket/seal. Apply the specified compatible PTFE thread seal, start by hand, then tighten firmly with the correct wrench. Do not cross-thread or overtighten.
Close the outlet. Confirm the ball valve is closed and added fittings do not place unsupported weight on the pot outlet.
Connect the pot lead with power off. Inspect the black/pin-style connector for dry, clean, straight contacts; align it correctly and seat it fully. Never twist, force, bridge or scrape contacts.
Match the electrical supply. The grounded receptacle/circuit must match each nameplate. Correct any voltage, grounding or capacity concern before plugging in.
Inspect—do not dry-heat. Confirm the complete system is clean, dry and secure. Do not turn on heat until approved material is loaded.

Daily use

Load, heat and process

Prepare the work area. Review the SDS and written batch procedure, put on PPE, lock every caster and clear the tilt/discharge area.
Inspect the system. Verify the pot is seated, outlet closed, connector fully seated, frame secure, controls dry and receiving vessel available.
Load before heating. Never preheat or operate empty. The supplied source manual calls for at least one-third full at batch start unless the exact model instructions require a different minimum. Stay below rated capacity and leave process-safe headspace.
Connect directly to the correct supply. Plug into the grounded nameplate-matched receptacle/circuit. Do not use an extension cord or power strip.
Turn on controls by function. Turn on main power if equipped, then the required heat control. Control colors can vary—use labels and the configuration record.
Set the approved temperature. Use the material manufacturer’s processing range and remain below the lowest limit among the material, pot, outlet/seal and equipment rating.
Use the lid when process-safe. It can improve uniformity and reduce heat loss. Control condensation and opening direction to avoid hot drips and vapor exposure.
Mix only by the approved method. Use the optional mixer instructions below or a compatible manual tool; never scrape or strike the heated pot or sensor area.
Monitor continuously. Review the controller with a suitable bulk-temperature method and watch for local overheating, leaks, abnormal sound, connector heat or frame movement.
Prepare to pour or shut down. Turn the mixer off before tilt preparation. Follow the next section for discharge; otherwise turn heat/main power off and unplug when safe.

Video: PRIMO heating and temperature-control overview

Use this for general PRIMO heat-control orientation only. Follow this page—not the video—for the tilting frame, removable pot, hot-discharge and optional-mixer procedures.

Controlled discharge

Tilt and pour safely

Plan the entire pour. Confirm the material is at an approved pouring condition, the batch volume is within the rating and the path will remain controlled from first movement through return to upright.
Stage the receiver. Use a stable, compatible, correctly sized container or mold within secondary containment. Position it before touching the tilt handle.
Secure the base. Verify every caster is locked and the frame does not rock. Never ask another person to hold the frame or receiver in place.
Stop and secure the mixer. Switch it off, wait for the blade to stop, unplug it and remove or secure the shaft/lid assembly exactly as its mounting instructions require.
Control the outlet. Use the intended valve or pouring path. Remove only components specifically intended for removal during pouring; never loosen the pot-to-valve connection while hot or full.
Clear people and obstructions. No hands, feet, cords, tools, clothing or containers may be below the pot, around the pivot or caster, or in the tilt/discharge arc.
Tilt slowly with continuous control. Use only the original handle and intended operator position. Do not jerk, bounce, climb on, add leverage to or release the moving kettle.
Reduce flow before repositioning. Return toward upright to slow or stop the stream. Never move the receiver beneath an uncontrolled pour.
Return fully upright. Confirm the pot is seated/captured, close the valve if used, wipe only when safe and keep the caster locks engaged until the unit is empty, cool and de-energized.
Shut down. Turn heat/main power off and unplug when safe. Do not remove the pot or move the frame until the material and equipment meet the written safe-handling condition.

Controller routing

Temperature controller

The supplied 2024 manual shows an Autonics TC4S-style controller. Other production years, replacement controllers, high-temperature builds and custom orders can differ. Match the controller face, model and temperature class before changing anything beyond the normal setpoint.

Basic TC4S operator steps—open only if the controller face matches

Change the normal setpoint

Press the up or down arrow to the approved process setpoint. Allow the display to finish blinking and save. Never exceed the lowest approved material or equipment limit.

Change Fahrenheit / Celsius

Press and hold MODE until PAR2 appears.
Press MODE until UNIT appears.
Use the arrows to select the unit, then press MODE to save.

Input calibration (IN-b)

Calibrate only with a suitable reference thermometer, a stable/mixed bulk sample and instructions for the exact controller. The correction equals actual bulk temperature minus the controller reading. Stop and contact Support if the required correction is large or unstable.

Temperature differential (HYS)

HYS is the number of degrees the process value falls before heat turns back on. Change it only with the exact process/controller instructions; changing it affects cycling and temperature swing.

Video: How to Reprogram a PRIMO Controller

Use only when the controller face and written settings for this exact kettle match.

Accessory instructions

Optional EZ-Mix / agitator

The mixer is a powerful high-torque tool and is sold/configured separately. Use these steps only when the installed shaft, blade, lid/channel mount, voltage and pot are approved together.

Assemble with all power off

Cool and de-energize. The pot and mixer must be safely empty/cool, switched off and unplugged.
Attach shaft and blade. Start the connection by hand, then tighten firmly with the specified wrench. Confirm the blade and shaft are straight and undamaged.
Install the lid/channel mount. Seat and secure it exactly as supplied so the shaft remains centered and cannot pull the lid or pot.
Check clearance by hand. With power disconnected, verify the blade cannot strike the bottom, side, valve path or temperature-sensing area.
Match power. Use the mixer nameplate supply. A step-down transformer may be required only when specified for that mixer.

Operate under continuous control

Load material first. Do not run the mixer dry. Confirm enough approved material covers the blade as required by the process.
Start at the lowest speed. Hold/control the mixer as designed, press the trigger and increase speed gradually while watching vibration and splash.
Never leave it unattended. Use a trigger lock only if the mixer is properly secured and the exact instructions authorize it; remain at the system and able to stop it immediately.
Stop for abnormal behavior. Shut down for blade contact, unusual vibration/noise, movement of the lid/mount, cord strain, odor, heat or loss of control.
Stop before any tilt. Release the trigger/lock, wait for a full stop, unplug and remove or secure the assembly as required before pouring.

Preventive care

Cleaning and maintenance

Before each use, inspect the pot, lid, valve/outlet, cradle, pivot, handle, stops/retainers, caster locks, cord, plug, controller, protector and pot connector.
Clean only after mixer, heat and main power are off, every plug is disconnected, and the material/equipment are at the safe condition in the SDS and process procedure.
Do not pressure-wash, hose or immerse the pot, frame, controller, connector or mixer. Keep every electrical component and contact dry.
Remove the pot only when it is safely emptied, cool, unplugged and disconnected from the controller. Use an approved lift/handling method; do not lift by the valve, cord or connector.
Clean the stainless process surface with a material-compatible method. Do not gouge, bend or aggressively abrade the pot, sensor area or valve seat.
Remove the valve only when the pot is safely emptied, cool and de-energized. Inspect the approved gasket/seal, compatible thread seal, valve stem/seat and outlet.
Keep connector contacts clean and dry. With power off, visually inspect for debris, bent pins, corrosion, charring or looseness; do not scrape, bridge or lubricate contacts without written instructions.
Keep the frame free of buildup. Check that tilt travel is smooth and stops/retainers remain secure using only an empty, cool, de-energized pot.
Inspect caster wheels and locks; remove the unit from service if a wheel, mount or lock is loose, cracked, bent or unable to hold.
Inspect the mixer shaft, blade, fastener, cord, lid/channel mount and clearance before every batch.
Periodically review controller temperature with a suitable calibrated bulk reference using a consistent fill and sampling method.
Do not bypass, up-rate or modify a fuse, breaker, controller, sensor, high limit, grounding provision, connector or wiring.
Internal electrical diagnosis, pivot/frame repair and component replacement are for qualified personnel working from WaxMelters instructions.

Troubleshooting

Start with the symptom—not an internal repair

Perform only external, visual and normal operator checks. Do not open enclosures, test live wiring, bypass controls, up-size protection, scrape energized connector pins, probe a hot outlet, force a jammed frame or repeatedly reset a tripping device.

Search this manual by symptom

Try: “no power,” “control on no heat,” “pin plug,” “breaker,” “slow heat,” “too hot,” “leak,” “poor pour,” “frame” or “mixer.”

Troubleshooting issueKettle will not turn onNo controller display or power indication

Troubleshooting issue

Kettle will not turn on

Stop if wet, hot or damaged. Do not energize a system with material on controls/connectors, a damaged cord/plug or a hot/discolored receptacle.
Verify the supply externally. Confirm the control-box plug is fully seated and the nameplate-matched dedicated outlet has power. Facility electrical checks belong to qualified personnel.
Use controls by function. Confirm main power, if equipped, then heat power are on. Do not rely on historic button colors.
Inspect the resettable protector. If visibly tripped, do not reset until the cause is understood and the controls/connectors are clean and dry.
Check the pot connection with all power off. Disconnect facility power, then verify the controller-to-pot plug is aligned and fully seated; do not force it.
Document and escalate. Photograph the nameplates, controller, controls, protector, both cord/plug connections and full system. Do not open the enclosure.

Apply only the external checks relevant to this removable-pot kettle.

Troubleshooting issueControl is on but the pot does not heatSeparate heat demand from the removable-pot connection

Troubleshooting issue

Control is on but the pot does not heat

Do not test empty. Confirm approved material is at or above the required minimum and the pot is fully seated.
Verify heat demand. Set the approved setpoint above current temperature and record whether the controller OUT indicator turns on.
Shut down before touching the connector. Turn heat/main power off and unplug from the facility supply.
Inspect the black/pin-style pot connector. Look for material, dust, moisture, bent pins, looseness, discoloration or charring. Do not scrape, spray, lubricate or bridge contacts.
Reconnect only if clean, dry and undamaged. Align and seat the connector fully; never force it. Restore power once and observe without touching the connector.
Stop if OUT is on with no heat. A secure clean connection that does not heat, or any connector warmth/odor/discoloration, requires Support. Do not open the pot or control box.

Troubleshooting issueFuse, protector, breaker or GFCI tripsTreat a repeat trip as a fault

Troubleshooting issue

Fuse, protector, breaker or GFCI trips

Do not repeatedly reset, bypass or up-size protection. A repeat trip, liquid near controls/connectors or a hot/discolored electrical connection requires shutdown and qualified evaluation.

Record when it trips. Note whether it occurs on plug-in, main power, heat demand/OUT, mixer start, after 5–10 seconds or later in the heat cycle.
Inspect only with every plug disconnected. Look for material at the valve joint, running down the pot, on controls/protector or at the pot connector. Photograph before cleaning.
Inspect the connector externally. Check for debris, moisture, bent pins, looseness or charring. Do not energize a damaged connector.
Check the facility load. Use the required dedicated, grounded circuit with no extension, power strip or other load. The mixer may require its own specified circuit.
Reset only for a confirmed external overload. If qualified facility personnel identify and remove another load as the sole cause, allow one controlled reset. If it trips again, stop.
Do not attempt a heater “dry-out.” Older documents mention moisture-related low insulation resistance. Testing and corrective drying require qualified procedures.
Submit the trip record. Include photos and circuit information; do not open the unit.

Troubleshooting issueKettle heats slowly, unevenly or not at allCheck fill, connection, demand, supply and heat loss

Troubleshooting issue

Kettle heats slowly, unevenly or not at all

Do not test empty. Confirm approved material is present at or above the model minimum; the supplied source manual calls for at least one-third full.
Verify heat demand. Set the approved setpoint above current temperature and record whether the controller OUT indicator turns on.
Verify the supply. Use the nameplate-matched dedicated circuit with a direct connection and no other loads.
Inspect the pot connection after shutdown. With all power disconnected, verify it is clean, dry, undamaged, aligned and fully seated.
Reduce heat loss. Use the lid when process-safe and move drafts, fans and open-door airflow away.
Mix and measure correctly. Follow the approved mixing procedure, then review a stable bulk sample with a suitable calibrated reference. A surface or valve reading is not bulk temperature.
Inspect after safe shutdown. Look for burned-on residue, discoloration or heavy buildup that can impair heat transfer or sensing.
Record performance. Provide material, volume, starting temperature, setpoint, actual temperature and elapsed time. Note whether heat stopped suddenly or declined over time.
Stop for abnormal behavior. OUT on with no heat, a tripping protector, hot connector or sudden loss after a surge/outage requires support.

Video: Heating Slowly, Unevenly or Not at All?

Troubleshooting issueTemperature is too highVerify actual bulk temperature and control response

Troubleshooting issue

Temperature is too high

If the material exceeds a safe limit: turn the mixer off, then heat/main power, and follow the SDS/facility controlled-cooling procedure. Do not tilt or pour an unstable, reacting or smoking batch.

Verify actual bulk temperature. Use a suitable calibrated reference and an approved, consistent mixed/sample location.
Record controller behavior. Note process value, set value and whether OUT remains on above setpoint.
Confirm adequate fill. Too little material can produce poor control and unsafe localized heating.
Lower the setpoint if permitted. Allow for normal thermal lag; temperature can rise briefly after output switches off.
Use only safe mixing/cooling steps. Opening the lid or mixing can create splash or vapor hazards; follow the material procedure.
Do not change advanced settings blindly. Match the exact controller and obtain its configuration before adjusting calibration, sensor, output or high limit.
Stop if control does not respond. Continued heating materially above setpoint, an implausible reading or abnormal OUT behavior requires shutdown and support.

Troubleshooting issuePot, valve or fitting is leakingControl the hot-material and electrical hazard first

Troubleshooting issue

Pot, valve or fitting is leaking

Keep the pot upright and stop all motion. Stop the mixer, then heat/main power. Do not tilt a leaking system.
Isolate the area. Follow the material SDS and facility spill procedure. Disconnect only if the access path and electrical area are dry and safe.
Photograph before cleanup. Capture the first wet point, complete valve joint, stem, added fitting, pot surface, lower electrical area, connector and full system.
Trace the source. Distinguish valve threads, valve stem/seat, downstream fitting and the pot itself. Liquid can travel before dripping.
Service only a confirmed threaded connection. After the pot is safely emptied, decontaminated, cool, unplugged and disconnected, inspect the compatible PTFE seal and factory gasket/seal; start by hand and tighten with the correct wrench.
Do not field-repair the pot or electrical area. Do not weld, drill, seal, open or energize it to “test” a leak without written authorization.
Submit full details. Include material, temperature, fill level and whether the leak changes with valve position.

Video: How to Troubleshoot a Tank / Valve Leak

Use the external leak-location steps only; this kettle has a removable pot and tilting frame.

Troubleshooting issuePour is slow, uneven or stoppedCheck process condition, valve/outlet and receiver position

Troubleshooting issue

Pour is slow, uneven or stopped

Return fully upright. Do not hover, shake or force the kettle in a partially tilted position while diagnosing flow.
Confirm the material is in the approved pouring condition. Verify bulk temperature, viscosity and mixing without exceeding any material or equipment limit.
Confirm valve position if used. On a standard ball valve, the handle aligns with the flow path when open. Do not force it.
Use normal kettle heat. Let the approved setpoint warm the outlet as designed. Never use a torch, heat gun or open flame.
Check the receiver and tilt path. Confirm the receiving opening is correctly aligned and large enough; never reposition it beneath an active stream.
Do not probe or pressurize. Keep hands, face and tools out of the hot outlet and do not add air pressure or unapproved pumping.
Inspect only after safe shutdown. Once safely emptied, cool, unplugged and disconnected, inspect/clean the outlet and valve by the material-specific procedure.
Escalate persistent poor flow. Send material details, bulk temperature, outlet/valve configuration and photos/video of the upright system and controlled symptom.

Troubleshooting issueTilt is difficult or the frame movesKeep the kettle upright until the mechanical concern is resolved

Troubleshooting issue

Tilt is difficult or the frame moves

Do not add leverage, loosen stops, climb on the frame or ask someone to hold it. Keep a loaded/hot kettle upright and establish a safe material-recovery plan with Support.

Stop operation. Stop mixer/heat/main power and keep people clear. Do not attempt another tilt with hot material.
Check caster locks without entering the hazard zone. Every lock must engage and the frame must remain stable. Do not wedge a defective caster as a substitute for repair.
Inspect after the system is empty, cool and de-energized. Look for a mis-seated pot, trapped cord, outlet interference, residue, bent part, loose fastener, cracked weld, damaged caster, stop or retainer.
Check empty travel only if safe and authorized. With the pot properly seated and all plugs disconnected, move through normal travel slowly. Stop at any bind, scrape, looseness or unexpected movement.
Do not lubricate or repair blindly. Lubricant, fastener grade, torque and alignment are configuration-specific and can contaminate product or reduce safety.
Send photos/video. Include the full frame on the floor, pot seating, both pivots, stops/retainers, handle and every caster/lock.

Troubleshooting issueMixer will not run or vibrates abnormallyCheck load, speed, mounting, clearance and power

Troubleshooting issue

Mixer will not run or vibrates abnormally

Release the trigger and unplug. Do not hold a stalled mixer on or restart one that struck the pot.
Confirm approved material covers the blade. Dry/underloaded operation can be loud, unstable and damaging.
Return speed to the lowest setting. High speed at startup can overload the motor or create severe splash.
Inspect the cold, de-energized assembly. Verify shaft/blade fastener, straightness, blade orientation, lid/channel mounting, pot seating and clearance.
Check electrical matching. Use the mixer nameplate supply and specified transformer/circuit. Do not share an undersized circuit with the kettle.
Clear process causes. Do not force the mixer through solid chunks or material above its approved viscosity; adjust only by the validated batch method.
Stop for continued vibration/noise or no-start. Send mixer nameplate, mounting, blade/shaft, pot fill and electrical-supply photos; do not open the mixer.
