STEP 6.
Reverse steps 1 through 3 to close the evaporator
fan panel.
Air Flow Obstructions
The unit must have free air flow to front grille to
operate properly.
Restricted air flow results in high head pressures
and reduction in efficiency due to longer run times.
Proper air flow around condensing unit and
evaporator is necessary for efficient operation.
• Never obstruct air flow in and out of
condensing unit.
• The front grille must be free from
obstructions, dust, and debris.
• Never obstruct air flow to Evaporator Fan.
• Make sure higher temperature ambient air
from another unit is not directed to
condenser coil (i.e. another condensing unit
directly across from the unit).
• Never place items in the area behind Product
Side Guard/Handle. See Figure 6-9.
Figure 6-9. Check for Obstructions
Clean Condenser Coil
ELECTROCUTION HAZARD!!
Never attempt to repair or perform
maintenance on the unit until the Main
electrical power has been disconnected.
Perlick’s warranty does not cover cleaning of
condenser.
The condenser is located directly behind the front
grille. See Figure 6-4.
Condenser coils that are covered with dust and
debris restrict air flow. This results in high head
pressures and lower efficiency due to longer run
times.
Use soft brush and vacuum to clean coil every 90
days, or more often if conditions require.
Ambient Temperature
High ambient temperature and high humidity
conditions may result in performance issues and/or
refrigeration system failure.
The unit must be protected from precipitation.
Do not subject to direct solar load.
Under extreme temperature and/or relative
humidity conditions the front face, gasket and/or
glass door may show signs of condensation. When
temperature and/or relative humidity conditions
return to normal condensation will disappear.
