Service and Installation Manual

MAINTENANCE

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 repeatedly 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 steels

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.

Never use an acid based cleaning solution！Many food products have an

acidic content which can deteriorate the finish. Be sure to clean the stainless

steel surfaces of ALL food products.

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. 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 don’t require the use of tools or authorized service technicians. The

gaskets are "Dart" style and can be pulled out of the groove in the door and replaced by pressing the new one

back into place.

Doors/Hinges

Over time and with heavy usage, door hinges may become loose. If the door begins 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 to both the doors and the door hinges. In some

cases, a qualified service agent or maintenance personnel is required to do this.

Drain Maintenance

Each unit has a drain located inside the unit which removes the condensation from the evaporator coil and

and drains the excess water into an 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 floor is not level this can also cause drain problems. Be sure all drain lines are

free of obstructions because obstructions may cause water to back up and overflow the drain pans.
