Care & Cleaning,

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 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.
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.
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.
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 or to the blower coil.
Overloading the storage area, restricting the airflow,
and continuous opening and closing of the doors and
drawers will hamper the units ability to maintain
operational temperature.
Refrigerated rail units
Product in the rail should be removed to the refrigerated base at the
end of the day. This allows you to turn the rail off at night to save
energy and to defrost the rail. It also helps maintain product quality.
The standard wrapped refrigerated rail units are controlled by a low-
pressure control that is set to maintain the proper rail temperature.
An on/off switch is also provided for the rail and is required to be shut
off at night. With a LiquiTec rail a thermostat is provided to maintain
rail temperature as well as the rail on/off switch. The LiquiTec rail
is required to be shut off at night as well to allow for defrosting. To
ensure product quality in the rail it is recommended that product be
rotated every four hours.
If adding any item to the unit, be sure to keep in mind
the location of the refrigeration lines on wrapped rail
units. A refrigeration leak in a rail is extremely difficult
and costly to repair. In some cases it cannot be repaired
at all.
Preventing blower coil corrosion
To help prevent corrosion of the blower coil, store all acidic items,
such as pickles and tomatoes, in sealable containers. Immediately
wipe up all spills.
Units with pans should be operated with pans in place.
Operating the unit without all pans in place will lower
efficiency and may damage the unit.
Continuous opening and closing of the doors will hamper the unit’s
ability to maintain optimum refrigeration temperature. Top section is
not intended for overnight storage. Product should be removed from
pans. Pans can remain in unit while empty.
