CASE CLEANING
A periodic cleaning schedule should be established to maintain
proper sanitation, insure maximum operating efficiency, and
avoid the corrosive action of food fluids on metal parts that are
left on for long periods of time. We recommend cleaning once
a week. Further suggestions for case cleaning include the fol-
lowing:
• To avoid shock hazard, be sure all electrical power is turned
off before cleaning. In some installations, more than one
disconnect switch may have to be turned off to completely
de-energize the case.
• All surfaces pitch downward to a deep-drawn drain trough,
funneling liquids to the center of the case where the waste
outlet is located for easy access. Check the waste outlet to
insure it is not clogged before starting the cleaning process
and avoid introducing water faster than the case drain can
carry it away.
• To clean the LED luminaires, shut off the lights in the case,
then wipe the luminaires down with a soft, damp cloth.
Avoid using harsh or abrasive cleaners as they may dam-
age the lights. Be certain that the luminaires are complete-
ly dry before re-energizing.
• Clean from top to bottom when cleaning the display case to
avoid cross contamination.
• If any potentially harmful cleaners are used, be certain
to provide a temporary separator (e.g., cardboard, plastic
wrap, etc.) between those cases that are being cleaned
and those that may still contain product.
• Avoid spraying any cleaning liquids directly on the electrical
connections.
• Allow cases to be turned off long enough to clean any frost
or ice from coil and pans.
• Remove toekick and clean underneath the case with a
broom and a long-handled mop. Use warm water and a dis-
infecting cleaning solution when cleaning underneath the
cases.

SHOCK HAZARD
Always disconnect power to case when servicing
or cleaning. Failure to do so may result in serious
injury or death.

Fig. 13 Pressure plate, screw locations and coil cover (topside)
Fans and Pressure Plate
1. Disconnect power to the case and wait for fans to come to
a complete stand-still.
2. To access the underside of the fans fi rst remove the
screws on the top ends and front sill of the pressure
plate cover (Fig. 13). Lift the pressure plate by use of the
provided lift handles (Fig. 14). There are hinges shared
between the pressure plate and coil covers. Note: It is
recommended that more than one person lift the pres-
sure plate. The topside of pressure plate will rest against
the topside of the coil cover, exposing the underside of the
pressure plate and fans (Fig. 15).
C A U T I O N
Only lift the pressure plate and/or coil cover for
a qualifi ed inspector or a trained service provid-
er. Failure to do so may result in damage to the
refrigerant system.

3. Clean as necessary. Use a spray bottle fi lled with an ap-
proved mild detergent and warm water.
4. Be sure to move the pressure plate back to its original
position after cleaning and/or inspection is complete.
