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 be- come 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

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 evapo- rates 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 col- lected 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.

Refrigeration Cycle

During the refrigeration cycle the evaporator fans will run continuously with the exception of door openings. The temperature control allows for the evaporator coil to clear after each off cycle and before the compressor runs again.

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 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

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 as- sembly 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 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. 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
