6. To set the proper spring tension and dispensing level,
place ten wax bases in the self-leveling dispenser on right
side of unit (Figure 1). Add or remove springs by hooking or
unhooking the bottom of the spring from the moving carriage
as necessary, until the top wax base is positioned at the
top of the dispenser unit (Figure 2).
!
NOTE: Steps 6 -8 are for Combination Plate/Base Heaters but may
be followed accordingly for plate or base only dispensers. Spring
adjustment not covered under warranty.
7. Repeat step 6 with plates for the other self-leveling
dispenser unit. In general, fewer springs will be needed to
maintain proper level for plates than for bases.
8. Remove all bases and plates from the self-leveling
dispensers, and carefully lower the self-leveling
dispensers back into the cabinet, taking care to place
base and plate dispensers in the appropriate side.
9. Be sure the power switches are in the OFF position before
plugging the power cord into the electrical outlet (Figure 3).
10. Select a location within reach of a 208, 220, 240 VAC,
60 Hz grounded NEMA No. 6-20R (2 Silo) or NEMA
No. 6-50R (3 silo) electrical outlet.
11. Place the unit near enough to the electrical outlet so
that the power cord is not stretched or strained when
plugged in.
12. When unit is properly located, engage the two caster
brakes by pushing down on the wheel brake lever.
13. See ELECTRICAL and START-UP sections before
plugging unit into power supply.
START-UP
Overview
These units are designed to heat stainless steel bases and
china plates. The fan motor, heating element, and power indi-
cator light will come on once the unit is turned on.
The fan motor will begin to circulate the heated air in
and around the plates/bases in a convection process that
promotes a quick and even heat absorption by the
plates/bases.
Once the air inside the cabinet has reached the desired and
preset temperature, the thermostats will continue to maintain
this temperature by regulating the power to the heating
element. The fan motor will run as long as each compartment
is energized.
ELECTRICAL
Refer to the General Information Section on page 2, your
local code or the National Electrical Code to be sure the unit is
connected to the proper power source. A protected circuit of
the correct voltage and amperage must be available for
connection of the line cord. Place the unit near enough to the
electrical outlet so the power cord is not stretched or strained.
Once the unit is properly located, push down on the two caster
brakes to lock them into place. All base/plate heaters are
provided with a NEMA plug type 6-20P (2 Silo) or 6-50P
(3 Silo).
!WARNING: Every base/plate heater is fitted with a grounded power
cord and must be connected to a properly grounded receptacle.
Each receptacle must be wired to a dedicated circuit breaker rated
at not more than 20 amps (2 Silo) or 50 amps (3 Silo).
!WARNING: To prevent electrical shock hazard, the main power
switch must be turned to “off” position and the heater disconnected
from the power source whenever performing service or
maintenance.
!WARNING: Hazardous voltage inside back of cabinet. Only
qualied personnel familiar with electrical circuits, service manual,
and service procedures should open or work inside unit.
!WARNING: Unit must not be run continually and must be turned off
after final meal service. Warranty may be voided if used improperly.
