Section 4 

Maintenance

DOORS/HNGES
Over time and with heavy use, doors and hinges may 

become loose. If this happens, tighten the screws that 

mount the hinge brackets to the frame of the unit. Loose or 

sagging doors can cause the hinges to pull out of the frame, 

which may damage both the doors and the hinges. In some 

cases this may require trained & qualified service agents or 

maintenance personnel to perform repairs. 
NOTE: Do not place hot pans on/against the blue ABS 

liner. Do not throw items into the storage area. Failure to 

follow these recommendations could result in damage to 

the interior of the cabinet. Overloading the storage area, 

restricting the airflow, and continuous opening and closing 

of the doors will hamper the unit’s ability to maintain 

operational temperature.

PREVENTNG CORROSON
Immediately wipe up all spills. 

OTHER MONTHLY TASKS
Cleaning the Cpndenser Cpil
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 at least every 

three months. If conditions are such that the condenser is 

totally blocked in three months, 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.

,

Cautipn

Never use a high-pressure water wash for this cleaning 

procedure as water can damage the electrical 

components located near or at the condenser coil.

GENERAL CLEANNG
nteripr Cleaning

Nptice

When cleaning interior and exterior of unit, care should 

be taken to avoid the rear power cord. Keep water and/or 

cleaning solutions away from electrical parts.

Imprtant

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.
Exteripr Cleaning

,

Cautipn

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.

Clean the area around the unit as often as necessary to 

maintain cleanliness and efficient operation.
Wipe gasket and 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.
