MAINTENANCE
MAINTENANCE – Door Gasket Care
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. Also, never 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 do not require the use of tools or authorized service persons. The gaskets are “Dart”
style and can be pulled out of the grove in the door and new gaskets can be “pressed” back into place.
MAINTENANCE – Drain
Each unit has a drain tube located in the rear the unit which removes condensation from the evaporator coil and
deposits it onto a drain pan where it can evaporate. If you notice excessive water accumulation on the inside of the
unit be sure that the drain tube is connected from the evaporator hous¬ing to the condensate evaporator drain pan.
If water is collecting underneath the unit you may want to check the condensate evaporator drain tube to be sure it is
still located above the drain pan. The leveling of the unit is also 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 the drain pan is kept free of
dirt, dust and other debris as excessive amounts will cause water to back up and overflow from the drain pan.
MAINTENANCE – Drain Pan Access
The drain pan and drain tube can be accessed from the rear of the unit. Pull the unit away from wall to expose the rear
of the cabinet. The drain pan is located on the left/rear of the unit.
