Cleaning The Condenser Coil; Drain Maintenance; Doors/Hinges - Delfield Shelleyglas KC-28 Installation, Operation And Maintenance Manual

Maintenance
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.

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 refrigerated 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 under the
unit, be sure the drain tube is connected to the evaporator
drain pan and 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.

DOORS/HINGES

Over time and with heavy-use doors, the 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 qualified service agents or
maintenance personnel to perform repairs.
