Specifications

The cleanliness and appearance of
this unit will contribute considerably
to operating efficiency and savory,
appetizing food. Good equipment
that is kept clean works better and
lasts longer.
THOROUGHLY CLEAN THE DISPLAY CASE
DAILY
1. Turn lights and adjustable thermostat(s) to the
“OFF” position.
2. Disconnect unit from power source by
turning breaker switch(s) to the "OFF" position.
3. Remove and store unused products under
refrigeration.
4. Clean the interior metal surfaces of the cabinet with a
damp cloth and any good alkaline or
alkaline chlorinated based commercial
detergent or grease solvent at the
recommended strength. Use a plastic
scouring pad or oven cleaner for
difficult areas. Avoid the use of
abrasive cleaning compounds, chloride
based cleaners, or cleaners containing
quaternary salts. Rinse well to remove
all residue and wipe dry.
NOTE: Never use hydrochloric acid (muriatic acid)
on stainless steel.
5. Clean glass with window cleaner.
6. To help maintain the protective film coating on
polished stainless steel, clean the exterior of the unit
with a cleaner recommended for stainless steel
surfaces. Spray the cleaning agent on the cloth and
wipe with the grain of the stainless steel.
Always follow appropriate state or local health
(hygiene) regulations regarding all applicable
cleaning and sanitation requirements for equipment.
Remember to turn the breaker switch(s) ON again
before operating the unit.
➥ White cotton gloves should be worn when handling quartz
elements. Never touch them with bare hands, as oil and dirt
from the skin can contaminate the quartz sheath and cause hot
spots and premature heater failure. If this element is touched,
thoroughly wipe, using a dry, clean cloth and alcohol or other
suitable solvent.
➥ Do not expose these heater elements to water.
➥ Solvent vapors can be flammable. Be sure to provide adequate
ventilation.
➥ Quartz heater elements are designed to be used in a horizontal
position only.
Installation
Care should be taken to insure that all installations meet
local code requirements and safety regulations. The quartz heater
will expand about 1% of its length. Be sure it is mounted to allow
this growth. Check the area around the quartz heat element for
flammable material.
Electrical
Never operate the quartz heater element at a voltage higher than
the design voltage. Disconnect and/or lock out power before
installing heater and making electrical connections. Make
electrical connections according to local, national or country codes.
Be sure all electrical connections are made safely and that the
terminals do not contact the housing. On units supplied with
leads, make certain the lead connections are tight before applying
power. When attaching leads to the heater element, be sure to
hold the inner terminal nut with pliers to prevent twisting or
breaking.
Operation
These heaters are designed to provide trouble-free operation;
however, some minimal precautions are required. Be sure the area
is free of flammable hazards. If the heaters are facing up, be sure
to remove objects that fall into the heaters or the reflectors behind
them. Periodically check to see that the wiring is not frayed, burnt,
or cut. If there is vibration, check to see that mounting screws
remain secure. The heaters will operate best with clean reflectors.
The loss of efficiency can be as high as 30% with dirty reflectors.
Always disconnect and lock out power before parts are replaced.
Replacement
Replacement is accomplished by removal of the screws holding the
end caps, removing the end caps, and disconnecting the power
leads from the terminals on the heater element. Installation is
accomplished by reversing the procedure.
Quartz elements should not be touched
with bare fingers as oil from hands can
destroy or cause premature failure.
If accidentally touched, clean with
a dry, soft cloth and rubbing alcohol.
