INSTALLATION
WARNING: FAILURE TO FOLLOW INSTALLATION GUIDELINES AND RECOMMENDATIONS
MAY VOID THE WARRANTY ON YOUR UNIT.
SELECTING A LOCATION FOR YOUR NEW UNIT
The following conditions should be considered when selecting a location for
your unit:
1. Floor Load: The area on which the unit will rest must be level, free of
vibration, and suitably strong enough to support the combined weights of
the unit plus the maximum product load weight.
2. Ventilation: The unit must not be inserted into a cabinet.
INSTALLATION CHECKLIST
WARNING: DAMAGE TO EQUIPMENT MAY RESULT IF NOT FOLLOWED. RANDELL IS NOT
RESPONSIBLE FOR DAMAGE TO EQUIPMENT IF IMPROPERLY INSTALLED.
NOTE: ALL MOTORS ARE OILED AND SEALED.
After the final location has been determined, refer to the following checklist
prior to start-up:
1. Check all exposed power cords and plugs to ensure that they are not
kinked, damaged, or show exposed wires.
2. Check that the thermostat knobs turn on/off and stop at the designated
position.
3. Unit must be properly leveled; check all legs or casters to ensure they
all are in contact with the floor while maintaining a level work surface.
Adjusting bullet feet heights or shimming casters may be necessary if the
floor is not level.
4. If wet operation is desired, add water as noted in Unit Operation for specific
model. Check for any sign of leaks.
5. Plug in unit and turn on thermostats. (Indicator lights for each well will
illuminate indicating the thermostat is calling for heat).
6. Allow unit time to heat water to temperature. (See Unit Operation.)
7. Refer to the front of this manual for serial number location. Please record
this information in your manual. It will be necessary when ordering
replacement parts or requesting warranty service.
8. Confirm that the unit is holding temperature. Set controls to desired
temperature for your particular ambient and altitude.
9. Allow your unit to operate for approximately 1 hour before putting in food
to allow unit to heat to storage temperature.
ELECTRICAL SUPPLY
The wiring should be done by a qualified electrician in accordance with local
electrical codes. A properly wired and grounded outlet will assure proper
operation. Please consult the data tag attached to the control panel to ascertain
the correct electrical requirements.

4. Wait 1 hour before adjusting thermostat. Higher number will increase
temperature. Lower number will decrease temperature.
5. Turn thermostat to off position when operation is completed.

for the unit achieving operating temperature sooner. Refilling of wet operation
units is required periodically if the water level is lower than 1”.

container. The drain valve can be found under the wells of the unit nearest the
left or right side wall of the lower shelf.
