Maintenance
Refrigerated Rail
Product in the rail should be removed to the refrigerated
base at the end of the day. The timer shuts off the rail for
the night. This saves energy and allows the rail to defrost. It
also helps maintain product quality. Pans can remain in unit
while empty.
Defrosting
Refrigerated cold pans should be defrosted daily. Never
use sharp objects or tools to clean or scrape ice/frost build
up from the refrigerated cold pans. A puncture to the pan
could cause irreparable damage to the refrigeration system.
Units with a Eutectic Fluid Cold Pan require the same
precautions. The fluid is NOT refillable and loss of fluid due
to a puncture would cause irreparable damage.

DRAWER CLEANING

Drawer Assembly
The drawer assembly should be cleaned weekly. Both
drawer and tracks are removable easily without tools. The
drawer tracks are dishwasher safe or can be cleaned in a
sink with detergents and a soft bristle brush.
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.
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.

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.

DRAIN MAINTENANCE

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.

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.
