stationary equipment in a Pollution Degree 2 and Over
voltage Category II environment.
This unit is designed to operate under the following
environmental conditions:
• Indoor use
• Altitude up to 2,000 m (6512 feet)
• Maximum relative humidity 65%, non-condensing
• Temperatures: 59°F to 90°F (15°C to 32°C)
• Main supply voltage fluctuations should not exceed by
-6% to +10% of the nominal voltage.

12
Installation
Selecting a Location
Choose a location for the FBV18FPSA that provides a
clearance of 12” at the top, 2” at the rear and 2” on each
side.
Appropriate electrical power must be available. Attach the
freezer to the facility’s electrical supply as directed by the

to accelerate the defrosting process, other than those
recommended by the manufacturer.
1. Remove all contents from freezer.
2. Turn o the unit at the controller or the power supply.
3. Place towels at the bottom of freezer to absorb water.
4. Defrosting may take up to several hours. To defrost
faster:
• Leave door open.
• Place pans of hot water on frost shelves.
• Wipe with warm towel or sponge.
CAUTION: Never use a knife or other metal
object to remove frost and/or ice.
Cleaning the Unit
Before beginning cleaning unit follow these instruction
listed below:
• Disconnect power cord from its outlet.
• The unit designs permit easy cleaning. Remember to
wear protective gloves to prevent frost bite, especially
when removing items from freezer units.
• Do not use abrasive scouring powders, waxes, solvents,
furniture polish, undiluted detergents or cleansers
containing petroleum products on the surfaces of units.
Cleaning Interior / Exterior /
Door Gaskets
The interior, exterior and the door gasket can be cleaned
using neutral cleaning agent and lukewarm water with a
soft, clean cloth. If this isn’t sucient, try ammonia and
water or a nonabrasive liquid cleaner.
Do not use an abrasive cleaner because it will scratch the
plastic and can damage the shelves and gaskets.
Rinse with clean water and dry thoroughly before
reconnecting and turning on the unit.
The cabinet interior should be cleaned frequently. Any
spilled liquid should be wiped o immediately since stains
resulting from some spills could be permanent if not quickly
removed. The most convenient time to clean the interior is
after defrosting.
CAUTION: Solutions used to clean coils
or neutralize bacteria growth must not be
corrosive to metals (enamel-coated steel)
and materials used in the maintenance of
this equipment-damage can result: use a
soft cloth and warm water to clean.
Cleaning the Condenser
With forced-fan vented units, remove the screws that
mount the grill to the unit. This will expose condenser for
cleaning.
These surfaces may be warm to the touch. The condenser
coil requires regular cleaning, and is recommended every
90 days. In some instances, you may find that there is a
large amount of debris and dust or grease accumulated
prior to the 90 day time frame. In these cases the
condenser coil should be cleaned every 30 days. If the
build up on the coil consists of only light dust and debris,
the condenser coil can be cleaned with a simple brush.
Heavier dust build-up may require a vacuum or even
compressed air to blow through the condenser coil.
