Service and Installation Manual
MAINTENANCE
Cleaning solutions need to be alkaline based or non-chloride based. If cleaners containing chlorides are
used, be sure to rinse and dry thoroughly. Routine cleaning can be done with soap and water. Extreme
stains or grease should be cleaned with a non-abrasive cleaner and plastic scrub pad. It is always good
to rub with the grain of the steel.
Gasket Maintenance
Gaskets require regular cleaning to prevent mold and mildew build up and also to keep the elasticity of the
gasket. Gasket cleaning can be done with the use of warm soapy water. Avoid full strength cleaning
products on gaskets as this can cause them to become brittle and prevent proper seals. Do not use sharp
tools or knives to scrape or clean the gasket which could possibly tear the gasket and rip the bellows.
Gaskets can easily be replaced and don’t require the use of tools or authorized service technicians.
The gaskets are "Dart" style and can be pulled out of the groove in the door and be replaced by pressing
the new one back into place.
Doors/Hinges
Over time and with heavy use, door hinges may become loose. If the door is beginning to sag, tighten the
screws that mount the hinge brackets to the frame of the unit. If the doors are loose or sagging, this can
cause the hinge to pull out of the frame which may damage both the doors and the door hinges.
Drain Maintenance
Each unit has a drain located inside the unit which removes the condensation from the evaporator coil and
evaporates it into an external condensate evaporator pan. Each drain can become loose or disconnected
from moving or bumping the drain. If you notice excessive water accumulation on the inside of the unit,
be sure the drain tube is connected from the evaporator housing to the condensate evaporator drain pan.
If water starts to collect underneath the unit, you may want to check the condensate evaporator drain tube
to be sure it is still located inside the drain pan. The leveling of the unit is important as the units are
designed to drain properly when on a level surface. If your floor is not level this can also cause drain
problems. Be sure all drain lines are free of obstructions because this can cause water to back up and
overflow the drain pans.
