Installation, Operation and Maintenance Instructions

When the equipment is received, all items should be carefully checked against the Bill of
Lading to ensure all crates and cartons have been received. Do not sign the freight bill
clear until the freight has been properly inspected for damage. All units should be inspected
for damage including concealed damage by uncrating immediately. If any damage is found,
it should be reported to the carrier at once, noted on the Bill of Lading and a claim should be
filed with the carrier. This equipment has been inspected and tested in the manufacturing
facility and has been crated in accordance with transportation rules and guidelines. The
manufacturer is not responsible for freight loss or damages.

INSTALLATION

Peel the protective covering before installation. After removing the covering, clean the
interior and exterior surfaces of the unit with soap and water and rinse with clean water. Do
not use chlorinated cleaners on the surfaces as they can cause corrosion.

The refrigeration system located on the right side of the unit requires free air access for
proper operation. Allow a minimum of seven (7) inches between the back of the cabinet and
the wall. Do not locate the unit next to heat generating equipment or in direct sunlight.

Confirm the proposed electrical outlet has the correct voltage, frequency and current
carrying capacity for the requirements of the unit. This information is noted on the data plate
on the inside left wall of the unit. The unit should be isol at ed on a cir c uit .

Do not use an extension cord to get power to the unit. Improper electrical installations will
void the compressor warranty. To prevent shock and fire, be sure the unit is properly
grounded.

OPERATION

Shelving

Remove shipping tie-straps from shelving to allow for slide by / easy access to lower shelves
/ chilled tableware. (Shelving is designed to slide, side to side, over existing shelves to allow
access to lower level(s), or the shelving can be easily removed (raise front edge of she lf up
and remove thru lid opening) and the Froster used without the shelving. The shelving design
allows the user to have chilled glassware / tableware on one side of the unit while chilling
glassware / tableware on the other side.

Control Setting

The temperature controller is located at the back, right inside the cabinet. Adjust the
temperature to fit your needs. Turn the control clockwise for cooler temperatures and
counterclockwise for warmer temperatures. Allow the unit several hours to respond to
temperature control adjustments.

Stock

When loading the cabinet with contents, do not block the fan in the back. Blocking the
air flow may decrease performance.

MAINTENANCE

General Cleaning

Beginning with the initial installation, the interior surfaces of the cabinet should be
periodically cleaned with a solution of warm water and baking soda. This solution will
remove any odors from spillage that has occurred. The exterior of the cabinet should also
be cleaned frequently with a commercial stainless steel cleaner, glass cleaner or mild soap
solution. Do not use chlorinated cleaners on the stainless steel surfaces.

The shelving can be cleaned in a sink with a mild soap solution and a soft bristled brush.
Periodically the unit should be emptied and cleaned out. There is a drain in the floor of the

cabinet that drains to a drain hose on the back of the cabinet in the compressor
compartment. Be sure to use this drain line for cleaning out the cabinet interior.

Condenser Coil Cleaning

Prior to cleaning the condenser coil, disconnect the unit from power. Periodic cleaning of
the condenser coil will aid the heat transfer of the refrigeration system and increase its
efficiency. To accomplish this, remove the front grill from the cabinet. The condenser coil
is located behind the grill. Use a soft bristled brush to remove any dirt particles that are on
the fins of the condenser coil. (GF50 only) Use a vacuum cleaner or compressed air to
remove the loosened particles. Replace the grill and reconnect the unit to power. Failure
to clean the condenser coil can lead to performance loss and compressor failure.
