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
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
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 drawer
tracks are dishwasher safe or 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
Pull the drawer box out until it stops. Lift up on the drawer
front and pull the drawer box 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.

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.
