MAINTENANCE
WARNING: When servicing any Capsule Pak™ Refrigeration System or performing any maintenance
procedure, always disconnect the main power supply.
The condensing unit is accessible by removing the condensing unit housing. The evaporator coil section is
accessible by unlatching and removing the evaporator section housing cover.
Cleaning the Condenser and Evaporator Coils
The efficiency of the refrigeration system, to a great extent, depends upon the unrestricted f.flow of air through the
condenser and evaporator coils. For this reason both coils should be as clean as possible at all times and should
have an unrestricted supply of air.
Cleaning the condenser should be done at a minimum of every 3 months.
A vacuum cleaner with a bristle attachment can be used to clean the coil. If debris on the coil cannot be removed
easily, a bristle brush can be used to loosen it by gently brushing in the same direction as the fins so as not
to damage them and restrict air flow. An air compressor can be used to clean the condenser coil also. The air
flow should be directed through the coil from the fan motor side. A damp hand towel can be blocked against the
opposite side so that the majority of the dust will be captured in the towel minimizing the mess in the room.
NOTE: Do not use corrosive cleaners as they may damage the copper tubing or welds.
Hot Gas Vaporizer Pan (Indoor Models)
Condensate from the evaporator pan is discharged into a hot gas vaporizer pan, which is located in the condensing
unit housing. Here the hot discharge gas from the compressor elevates the temperature of the water and it
vaporizes into the atmosphere. This pan should be cleaned periodically to remove solids that remain after the
moisture is evaporated. Do not scrub the copper tubing very hard or use corrosive cleaners as this may
damage the copper lines or welds.
