done at least every three months. If conditions are such that the condenser is
totally blocked in three months, the frequency of cleaning should be increased.
Clean the condenser with a vacuum cleaner or stiff brush. If extremely dirty, a
commercial-grade condenser cleaner may be required.
STAINLESS STEEL CARE AND CLEANING
To prevent discoloration of rust on stainless steel several important steps need to
be taken. First, we need to understand the properties of stainless steel. Stainless
steel contains 70-80% iron which will rust. It also contains 12-30% chromium
which forms an invisible passive film over the steels surface which acts as a
shield against corrosion. As long as the protective layer is intact, the metal is still
stainless. If the film is broken or contaminated, outside elements can begin to
breakdown the steel and begin to form rust of discoloration. Proper cleaning of
stainless steel requires soft cloths or plastic scouring pads, Cleaning solutions
need to be alkaline based or non-chloride based. Any cleaner containing
chlorides will damage the protective film of the stainless steel. Chlorides are
commonly found in hard water, salts, and household and industrial cleaners.
If cleaners containing chlorides are used, be sure to rinse and dry thoroughly.
Routine cleaning of stainless steel 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. There are also stainless
steel cleaners available which can restore and preserve the finish of the steel's
protective layer.
Early signs of stainless steel breakdown can consist of small pits and cracks.
If this has begun, clean thoroughly and start to apply stainless steel cleaners in
attempt to restore the passivity 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
grove in the door and 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 may cause water to back up and overflow the drain pans.
