SHOCK HAZARD
Always disconnect power to case when servic-
ing or cleaning. Failure to do so may result in
injury or death

C A U T I O N
Exercise extreme caution when working in a
case with the coil cover removed. The coil con-
tains many sharp edges that can result in
severe cuts to the hands and arms.

Power cord must be pushed back through the
plenum opening before removing the fan bas-
ket. Failure to do so may result in damage to
the power cord.

FANS
Hillphoenix door cases feature electronic commutated fan
motor assemblies. The fans have a factory-set blade
pitch and a pre-con
fi
gured RPM speci
fi
c to each model.
Fan assemblies may be changed with an easy two-step
process without lifting up the plenum, thereby avoiding
the necessity to unload the entire product display to
change the fan assembly:
1.
Unplug the fan motor (Fig. 11) from the receptacle on
the exterior of the fan plenum. Push the power cord back
through the plenum opening.
2.
Remove fasteners, then lift out the entire fan basket.
(Reverse procedure when re-installing fan assembly.)

CLEANING PROCEDURES
A periodic cleaning schedule should be established to
maintain proper sanitation, insure maximum operating ef
fi
-
ciency, and avoid the corrosive action of food
fl
uids on
metal parts that are left on for long periods of time. We
recommend cleaning once a week.
•
Be certain that all electricity to the case is turned off
before servicing or cleaning to avoid electrical shock.
In some cases, more than one switch may need to be
turned off to completely de-energize the case.
•
All surfaces pitch downward to a deep-drawn drain
trough, funneling liquids and other debris to the waste
outlet. Check waste outlet before starting the cleaning
process to insure it is unclogged. Avoid introducing water
faster than the case drain can carry it away.
•
Lift the fan plenum to gain access to the coil for cleaning
and maintenance (Fig. 12).
•
To clean the lights, shut off the lights in the case, then
wipe them down with a soft, damp cloth. Avoid using
harsh or abrasive cleaners as they may damage the
lights. Be certain that the lights are completely dry before
re-energizing.
•
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 cleaning solutions directly on electrical
connections.
•
Allow cases to be turned off long enough to clean any
frost or ice from coil and pans.
•
Remove kickplate and clean underneath the case with a
broom and a long-handled mop. Use warm water and a
disinfecting cleaning solution when cleaning underneath
the cases.
