CLEANING PROCEDURES

• 

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.

• 

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 front of the case where 
the waste outlet is located for easy access.  Check 
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.

• 

The coil is covered to keep food fluids from entering 
but is easily accessible when coil cleaning is required. 
Simply remove the screws; lift and remove the plenum 
cover; then lift and remove the coil cover. Be certain that 
both the plenum and coil cover are properly closed and 
secured after cleaning to avoid air leaks.

• 

If any potentially harmful cleaners are used, be certain 
to provide a temporary separator (e.g., cardboard, plas-
tic rap, 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.

SHOCK HAZARD

Always disconnect power to case when servic-

ing or cleaning.  Failure to do so may result in 

serious injury or death.

Exercise extreme caution when working in a 

case with the coil cover removed.  The coil 

contains many sharp edges that can result in 

severe cuts to the hands and arms.

FANS

The evaporator fans are equipped with 16-watt fan motors.  
Motors have a counter-clockwise rotation when viewed 
from the shaft end.  

The fan blades are 8” in diameter with a 20

o

 fan blade 

pitch.  It is important that the blade pitch be maintained as 
installed.  

Do not attempt a field modification by alter-

ing the blades.

Fan motors may be changed with an easy two-step pro-
cess without lifting up the plenum, thereby avoiding the 
necessity to unload the entire product display to make a 
change:

1.  Unplug the fan motor, easily accessible outside the  

plenum.  Push power cord back through plenum 
opening.

2.  Remove two fasteners, then lift out the entire fan 

basket.

Reverse procedure when re-installing fan basket.
