Installation
As with any refrigerated cabinet, there are
several very important requirements that must be
complied with for proper operation. They are as
follows:
1. This line of cabinets are designed to operate in
a location with an ambient temperatures of 75
o
F
and a relative humidity of 55%. This cabinet
should not be located in an area the cabinet may
be subjected to radiant heat from spot or flood
lamps, sun rays or heat from suspended gas
heating fixtures.
2. After locating the cabinet, it must be leveled
from front to back as well as end-to-end. This will
facilitate proper refrigeration at the evaporator
and proper dissipation of the defrost water.
3. The minimum clearance allowed for the rear of
the cabinet is 3 inches and the sides can have no
clearance if need be.
4. All wiring must be installed by a competent
electrician and conform to local codes. The
incoming voltage must be maintained to within 5%
of the voltage shown on the cabinet nameplate.
Electrical Service Connection
Some of the models are provided with a Service
Power Cord, see the Engineering
Specifications for the plug type of your cabinet.
Locate the electrical outlet in such a manner that
you may plug in the service cord directly, without
the use of an extension cord. The electrical outlet
used to supply the cabinet must have proper
ground facilities to match the service plug on the
cabnet service cord. Make sure that no other
electrically operated devices are connected to
the circuit operating this cabinet, which will cause
an overload. Overloaded circuits are extremely
hazardous.
The electrical connection for models that are not
supplied with a Service Power Cord is to be made
in junction box located at the rear of the cabinet
(see applicable Plan View drawing for exact
location).
The incoming voltage must be maintained to
within 5% of the voltage shown on the nameplate.
Howard-McCray will not accept responsibility for
the performance of the cabinet or malfunction of
any component due to a incorrect voltage supply
than that indicated on the serial rating plate. Use
separate electrical supply lines connected to a
fuse block or circuit breaker of proper capacity.
Caster or Leg Installation
Most cabinets are supplied with a set of casters.
These casters are shipped as separate items and
will need to be installed before the cabinet is
located in position. See the Caster Installation
drawing for exact instructions.
Some cabinets are ordered and supplied with
adjustable legs. These legs and mounting plates
are shipped as separate items and will need to be
installed before the cabinet is located in position.
See the Leg Installation drawing for exact
instructions.
NOTE When installing either Casters or Legs,
take all necessary safety precautions when
elevating the cabinet.
Condensate Evaporator Pan
An electric condensate evaporator pan is
furnished with the cabinet, to dissipate the water
collected from the coil during defrost or off cycle.
The evaporator pan and it's mounting bracket are
shipped as a separate items. The evaporator pan
is equipped with a power cord for plugging into a
115VAC NEMA 5-15R outlet. To install the
evaporator see the Condensate Pan
Instruction drawing for exact instructions.
Drain Trap Installation
A properly installed drain trap is extremely
important in ensuring satisfactory cabinet
operation, and protection from product loss. The
drain hose on this model is factory attached to the
rear of the cabinet. The drain hose is supplied at
a length sufficient to reach the floor, when the
cabinet is equipped with either casters or legs.
After installing the factory supplied Electric
Condensate Pan loosen the drain hose
attachement clamps that hold the drain hose in a
loop. Configure the drain hose on the rear of the
cabinet so that it is oriented vertically to the
condensate pan. Locate the factory supplied
drain trap so that it exits (in a vertical orientation)
into the Electric Condensate Pan. Determine
where the drain hose will overlap the drain trap
by a minimum of 2" and cut the hose to this
length. Insert the drain trap into the drain hose
and secure them to the rear of the cabinet.
NOTE Never route the drain hose directly into the
Electric Condensate Pan, the heat of the pan will
damage the drain hose.
