Maintenance Section 4

INTERIOR CLEANING

Warning

When cleaning interior and exterior of unit, care should

be taken to avoid the front power switch and the rear

power cord. Keep water and/or cleaning solutions away

from these parts.

Warning

Never use a high-pressure water jet for cleaning or hose

down or flood interior or exterior of units with water. Do

not use power cleaning equipment, steel wool, scrapers

or wire brushes on stainless steel or painted surfaces.

The interior can be cleaned using soap and warm water. If

this isn’t sufficient, try ammonia and water or a nonabrasive

liquid cleaner.

Preventing Blower Coil Corrosion

To help prevent corrosion of the blower coil, store all acidic

items, such as pickles and tomatoes, in seal-able containers.

Immediately wipe up all spills.

EXTERIOR CLEANING

Caution

Never use an acid based cleaning solution on exterior

panels! Many food products have an acidic content,

which can deteriorate the finish. Be sure to clean the

stainless steel surfaces of ALL food products.

Clean the area around the unit as often as necessary to

maintain cleanliness and efficient operation.

Wipe exterior surfaces with a damp cloth rinsed in water to

remove dust and dirt from the outside of the unit. Always

rub with the “grain” of the stainless steel to avoid marring

the finish. If a greasy residue persists, use a damp cloth

rinsed in a mild dish soap and water solution. Wipe dry with

a clean, soft cloth.

Never use steel wool or abrasive pads for cleaning. Never

use chlorinated, citrus based or abrasive cleaners.

Stainless steel exterior panels have a clear coating that

is stain resistant and easy to clean. Products containing

abrasives will damage the coating and scratch the panels.

Daily cleaning may be followed by an application of

stainless steel cleaner which will eliminate water spotting

and fingerprints. Early signs of stainless steel breakdown

are small pits and cracks. If this has begun, clean thoroughly

and start to apply stainless steel cleaners in attempt to

restore the steel.

Gasket Cleaning

Gaskets require daily 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.

Drawer gaskets are magnetic and mount to the drawer,

snapping in place and are removable without tools.

CASTERS

Wipe casters with a damp cloth monthly to prevent

corrosion.

Section 4 Maintenance

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.

Tracks

The drawer box assembly must be removed. Pull the drawer

tracks out until they hit a stop. Locate blue safety clips

towards the back of each drawer track. Blue safety clips

have a tab on the top. Push the tab back until it clicks. Lift

up and pull the drawer tracks all the way out of the drawer

cage. 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.

Using a soft bristle brush, wash the track making sure each

roller is thoroughly cleaned. The drawer cage 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.

Tab on top of blue safety clip

Reassembly

Push the drawer tracks into the drawer cage. The blue safety

clip must remain pushed towards the back. Lift up and slide

the drawer track all the way into the drawer cage. The blue

safety clip will lock in place automatically. Once all tracks

are replaced, insert the drawer box. Rest the drawer box

bottom track on the front 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.

DRAIN

Each unit has a drain located inside the unit that removes

the condensation from the evaporator coil and routes it

to an external condensate evaporator pan. Each drain can

become loose or disconnected during normal use. If you

notice water accumulation on the inside of the unit, be sure

the drain tube is connected to the evaporator drain pan.

If water is collecting underneath the unit, make sure the

end of the drain tube is in the condensate evaporator. The

leveling of the unit is important as the units are designed to

drain properly when level. Be sure all drain lines are free of

obstructions.

CLEANING THE CONDENSER COIL

In order to maintain proper refrigeration performance, the

condenser fins must be cleaned of dust, dirt and grease

regularly. It is recommended that this be done monthly. If

conditions are such that the condenser is totally blocked

in a month, 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.

Failure to maintain a clean condenser coil can initially cause

high temperatures and excessive run times. Continuous

operation with a dirty or clogged condenser coil can

result in compressor failure. Neglecting the condenser coil

cleaning procedures will void any warranties associated

with the compressor and cost to replace the compressor.

FIELD INSTALLATION

Over shelves and other items mounted to the top of the

counters should never be installed in the field due to the

potential damage to the refrigeration system.
