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. Also, never use sharp tools or
knives to scrape or clean the gasket which could possibly tear the
gasket and rip the bellows.
F15 Base Only
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.
Doors/Hinges
Over time and with heavy use, door hinges may become loose.
If it is noticed that the door is beginning to sag, it may become
necessary to 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. In some cases this can require qualied
service agents or maintenance personnel.
Drain Maintenance
Each unit has a drain located inside the unit which removes the
condensation from the evaporator coil and evaporates it at 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 is collected 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 oor is not level this can also cause
drain problems. Be sure all drain lines are free of obstructions,
typically food product is found blocking drain lines causing water to
back up and overow the drain pans.
The power must be turned off and disconnected
whenever performing maintenance or repair functions.
Cleaning the Condenser Coil
The condenser coil requires regular cleaning, recommended is every
90 days. In some instances though you may nd that there is a large
amount of debris and dust or grease accumulated prior to the 90
day time frame. In these cases the condenser coil should be cleaned
every 30 days.
If the build up on the coil consists of only light dust and debris the
condenser coil can be cleaned with a simple brush, heavier dust build
up may require a vacuum or even compressed air to blow through the
condenser coil.
If heavy grease is present there are de-greasing agents available
for refrigeration use and specically for the condenser coils. The
condenser coil may require a spray with the de-greasing agent and
then blown through with compressed air.
Failure to maintain a clean condenser coil can initially cause high
temperatures and excessive run times, continuous operation with
dirty or clogged condenser coils can result in compressor failures.
Neglecting the condenser coil cleaning procedures will void any
warranties associated with the compressor or cost to replace the
compressor.
Never use a high pressure water wash for this
cleaning procedure as water can damage the
electrical components located near or at the
condenser coil.
In order to maintain proper refrigeration performance,
the condenser ns must be cleaned of dust, dirt and
grease regularly. It is recommended that this be 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 commercially available condenser
cleaner may be required.
