voltage drops. As a result, the power to the
merchandiser may be interrupted and freezing
performance can be adversely affected which may
cause equipment damage and /or product loss.
Voltage supply to the merchandiser must not vary
more than ±10 percent of the normal 115V.
Information regarding the electrical voltage and
frequency being supplied to the merchandiser can
be found on the merchandiser’s serial data plate
typically located at the upper left corner of the
merchandiser’s interior. Information regarding the
maximum fuse/circuit breaker size required for
the specific model is available from the
condensing unit data plate.
Plug Units:
Units that have a plug style condensing unit and
evaporator will need to be unpackaged and
installed on top of the unit. The completed plug
weighs approximately 150 pounds. An
appropriately rated, mechanical lifting device
should be used to prevent injury. If one is not
available and due to the weight of the plug unit, it
is recommended to use a two person lift to
manually install. Use caution to prevent damage
to the drain pan nipple upon installation. Do not
lay the evaporator housing directly on any surface
as the weight of the compressor could damage the
fans or drain nipple. Once installed, lighting, door
switch connections (if applicable) and grounding
will need to be made on top of the unit.
Condensate Evaporator:
Indoor auto-defrost models are supplied with a
condensate evaporator heater assembly which is
packaged and shipped inside the merchandiser. It
will require simple installation by the consumer
(see
Figure 1
). A separate copy of this instruction
sheet is supplied with the condensate evaporator
assembly.
The condensate evaporator assembly contains a
drip pan to collect water generated by the
merchandiser’s defrost cycle and a heat element to
evaporate the water. Once energized, the heat
element in the condensate evaporator assembly is
continuously generating heat. The merchandiser is
to be placed so that there is at least 1 inch of air
space between the back surface of the condensate
evaporator housing and any wall surface behind
the cabinet which allows for heat dissipation away
from the surface of the wall. The main power cord
should also be routed to avoid pinching.
Note:
Do not operate an indoor auto-defrost
merchandiser without having a condensate
evaporator assembly installed under the
evaporator drain tube exiting the back wall of the
cabinet. Failure to install this assembly will result
in water draining directly onto the floor during the
defrost cycle. This may result in water damage to
the floor and create a hazardous slip condition in
the area surrounding the merchandiser.
