DO NOT perform
these procedures
while the cabinet is
turned on or heated.
Turn off the power
and wait until it has cooled to room
temperature before starting.
WARNING
CASTERS
Caster bearings are equipped with Zerk grease fittings so that they may be
easily lubricated with a grease gun. Lubricate bearings at least once every six
months. Lubrication will be required more often if the cabinet is cleaned with a
hot water or steam cleaning system. (Casters with special Delrin
TM bearings are
recommended for frequent cabinet cleaning with steam cleaning systems or high
pressure hose.)
LATCHES
Check frequently to insure that door latch is secure. Latch may become “sticky”
due to residue build-up from daily use and cleaning. Lubricate latches regularly
with WD40, silicone spray, graphite or other commercial lubricants for stainless
steel products. Do not use oil.

Maintenance
T H E R M O M E T E R C A L I B R AT I O N
Place an oven thermometer in the center of the cabinet. Turn heater on;
turn thermostat to maximum setting and wait approximately 45 minutes.
Open the door and check inside thermometer temperature. If recalibration
is required, pry the plastic cover off the dial body and with a small flat blade
screwdriver, insert into the pointer as shown. Carefully turn the pointer with
your finger to the correct setting. Be careful not to bend the pointer. It is
very fragile.
T H E R M O S TAT C A L I B R AT I O N
If additional heat range is required in the heating unit, unplug unit, remove
black thermostat knob, insert small straight blade screwdriver into opening
and turn limit control set screw counter clockwise one full turn. Replace
thermostat knob and turn clockwise to reach new maximum temperature.
Repeat this until desired temperature is reached. Each 1/4 turn of the
calibration set screw will raise the heating element capacity by
approximately 25-35
o F.
If a reduction in heat is desired, turn limit control set screw clockwise one
full turn. Hold the door open, allowing unit to cool until inside temperature
is below the temperature desired. Close the door and allow unit to rise to a
new maximum temperature. Repeat this until desired temperature is
reached.
