BUFFET WARMER & HORS
D'OEUVRE WARMER
The infrared heat and incandescent lights are controlled by
a toggle switch. This switch must be in the "on" position
when using. If the unit is equipped with an optional infinite
switch, this switch will control the heat and the toggle will
activate the lights only.
The heated base is controlled by an "on/off" rocker switch
and a thermostat adjustment knob.
HEATED DISPLAY CASE
The infrared or "top heat" is controlled by 2 knobs with
variable settings from low to high. The heated base or "bottom heat" control can be set to any desired level. A toggle
switch activates the cabinet lights.
NOTE
Lights, top heat and bottom heat can be operated
simultaneously or separately.
To preserve the finish of your Glo-Ray Display Warmer, it is
recommended that exterior surfaces be wiped daily with a
damp cloth. Stubborn stains may be removed with a good
aluminum or stainless steel cleaner or a non-abrasive
cleanser. Use a glass cleaner on all glass panels and doors.
CAUTION
Use only non-abrasive cleaners. Abrasive cleaners
could scratch the finish of the Food Warmer marring its
appearance and making it susceptible to soil
accumulation.
Glo-Ray food holding pans are available in thermoaluminum or stainless steel and should be removed from
the food warmer for washing and sanitizing after each use.
Breath protectors may be removed for thorough cleaning
and polishing. They should be wiped daily with a soft, damp
cloth. If fine scratchs are present, a good acrylic cleaner
may be used to polish the breath protectors and remove the
scratches.
CAUTION
Only soft cleaning cloths should be used to clean
breath protectors. Breath protectors are made of
shatter-proof acrylic and will scratch if proper care is
not taken.
