MAINTENANCE (cont.)
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 grove in the door and replaced by pressing the new one back into
place. It is recommended to help hold the gasket in place that every 10” (260mm) a dab of gasket adhesive be
applied to help the slot retain the gasket in 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 to 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 may cause
water to back up and overflow the drain pans.
