INTERIOR CLEANING
n
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.
n
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.
