DOOR GASKET MAINTENANCE
Door gaskets require regular cleaning to prevent mold
and mildew buildup and also to retain 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 crack. Never use sharp tools or
knives to scrape or clean the gasket. Gaskets can be
easily replaced and do not require the use of tools or
an authorized service person. The gaskets are “Dart”
style and can be pulled out of the groove in the door
and new gaskets can be “pressed” back into place.
DRAIN MAINTENANCE - BASE
Each unit has a drain located inside the unit that
removes the condensation from the evaporator coil
and routes it to an external condensate evaporator
pan. Each drain can become loose or disconnected
during normal use. If you notice water accumulation on
the inside of the unit, be sure the drain tube is
connected to the evaporator drain pan. If water is
collecting underneath the unit, make sure the end of
the drain tube is in the condensate evaporator in the
machine compartment. The leveling of the unit is
important as the units are designed to drain properly
when level. Be sure all drain lines are free of
obstructions.
! Warning
Disconnect power to the unit before performing
any service or maintenance functions.
