BASIC MAINTENANCE
gasket Maintenance
Gaskets require regular cleaning to prevent mold and
mildew build up and also to maintain 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 groove in
the door and new gaskets can be “pressed” back into
place.
doors/Hinges
Over time and with heavy use the door hinges may
become loose. If it is noticed that the door is beginning
to sag, it may be necessary to tighten the screws that
mount the hinge brackets to the frame of the cabinet,
Figure 6. 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
to the condensate evaporator drain pan. If water has
collected underneath the cabinet, check the condensate
evaporator drain tube to be sure it is still located inside
the drain pan. Leveling the cabinet is important as it is
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. Typically,
food product is found blocking drain lines causing water
to back up and overflow the drain pans.
drawer Maintenance
drawer Assembly Cleaning
The drawer assembly is designed to be cleaned easily.
Both drawer and tracks are removable without tools.
The intermediate drawer tracks are removable and can
be cleaned in a sink with detergents and a soft bristle
brush. Drawers and tracks should be cleaned on a
weekly basis.
Remove drawers
To remove a drawer, simply pull the drawer out until it
stops. At this point lift up on the drawer front and pull the
drawer completely out. Using a soft bristle brush, clean
the track on the bottom of the drawer box. When finished,
it should be wiped clean of all food and debris.
Tracks
To remove the intermediate tracks, the drawer box
assembly must be removed. The intermediate tracks are
removed by pulling the track out 1.50” to 2.00” (3.8cm to
5.0cm). Line up the rear white roller with the half moon
notch in the outer profile, and then rotate the track away
from the outer track profile freeing the intermediate profile.
The intermediate drawer tracks can be cleaned in a sink
with detergents and a soft bristle brush. Drawers and
tracks should be cleaned on a weekly basis. Using a soft
bristle brush, wash the intermediate track making sure
each roller is thoroughly cleaned. The outer profile track
should be cleaned with a soft bristle brush, removing any
food and debris gathered on the bottom ledge. Once
it’s cleaned thoroughly with a soft bristle brush, wipe
remaining debris clean with a soft towel.
Reassembly
Place intermediate tracks back into the outer track profile by
lining up the rear roller with the half moon notch and rotating
towards the outer profile. Once all tracks are replaced, insert
the drawer box. Rest the drawer box bottom track on the
front intermediate track roller. Then push the drawer back in
place SLOWLY. When the drawer box is about half way in
you will hit a STOP. You must lift the front of the drawer up
approximately ½” (1.3cm) to continue inward. Clean tracks
as often as possible. The cleaner the tracks are the better
they will operate.

this may require repair by a qualified service agent or
maintenance personnel.
drain Maintenance
Each cabinet has a drain located inside 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 cabinet, be sure the
drain tube is connected from the evaporator housing
