Receiving And Inspecting The Equipment

Even though most equipment is shipped crated, care should be
taken during unloading so the equipment is not damaged while
being moved into the building.

1. Visually inspect the exterior of the package and skid or
container. Any damage should be noted and reported to
the delivering carrier immediately.

2. If damaged, open and inspect the contents with the
carrier.

3. In the event that the exterior is not damaged, yet upon
opening, there is concealed damage to the equipment
notify the carrier. Notification should be made verbally as
well as in written form.

4. Request an inspection by the shipping company of the
damaged equipment. This should be done within 10 days
from receipt of the equipment.

5. Check the lower portion of the unit to be sure legs or

6. Also open the compressor compartment housing and

7. Freight carriers can supply the necessary damage forms

8. Retain all crating material until an inspection has been

Uncrating the Equipment

First cut and remove the banding from around the crate.
Remove the front of the crate material, use of some tools will
be required. If the unit is on legs remove the top of the crate
and lift the unit off the skid. If the unit is on casters it can be
"rolled" off the skid.

casters are not bent.

MCCPT Series Service and Installation Manual

CAUTION

Installation

Location

These units are intended for indoor use only. Be sure the location
chosen has a floor strong enough to support the total weight of the
cabinet and contents. A fully loaded 72” long model may weigh as
much as 1200 pounds. Reinforce the floor as necessary to provide
for maximum loading.

For the most efficient refrigeration, be sure to provide good air
circulation inside and out.

Inside cabinet: Do not pack refrigerator so full that air cannot
circulate.

Outside cabinet: Be sure that the unit has access to ample air. Avoid
hot corners and locations near stoves and ovens.

It is recommended that the unit be installed no closer than 1” from
any wall.

Leveling

A level cabinet looks better and will perform better because the drain
pan will drain properly, the doors will line up with the frames properly,
and the cabinet will not be subject to undue strain.

Some models have casters for your convenience, for ease of cleaning
underneath and for mobility. It is important that the unit be installed in
a stable condition with the front casters locked before operating.

Plumbing

Self-contained models are standard with a condensate evaporator. If,
for some reason, a unit does not have a condensate evaporator, or the
evaporator fails, the unit’s drain must have an outlet to an appropriate

drainage area or container.

Moisture collecting from improper drainage can create
a slippery surface on the floor and a hazard to
employees. It is the owner’s responsibility to provide
a container or outlet for drainage.

Electrical connection

Refer to the amperage data on page 3, the serial tag, your local code
or the National Electrical Code to be sure the unit is connected to the
proper power source. A protected circuit of the correct voltage and
amperage must be run for connection of the line cord, or permanent
connection to the unit.

The power switch must be turned to OFF and the
unit disconnected from the power source whenever
performing service or maintenance functions.

Never operate the unit without the louvered panel in
place!

Operation

MCCPT Series Service and Installation Manual

Product should be loaded into the unit with care.
Failure to heed these recommendations could result
in damage to the interior of the cabinet or the blower
coil.

This unit is equipped with two ON/OFF switches located behind the
louvered machine compartment panel. The unit’s compressor and all
evaporator fans will begin operating when the main power switch is
turned to the ON position. Temperature ranges for the base are 36°F
to 40°F.

The switch labeled rail is for the raised rail. The rail switch is accesible
through a 1.5” diameter hole in the louvered panel. Turning this
switch to the ON position will activate the refrigeration for the rail.
Temperature ranges for the raised rail are 33°F to 41°F.

Product located in the rail must be removed at the end of
day. This allows you to turn the rail off at night to save
energy and the rail will have time to defrost as needed.

Refrigerant Charges

MCCPT-48. . . . . . . . . . . . . . . . . . . . . . . .16 oz.

MCCPT-72. . . . . . . . . . . . . . . . . . . . . . . .32 oz.

MCCPT-99. . . . . . . . . . . . . . . . . . . . . . . .48 oz.

A minimum of one hour of off time per day with the pans removed
from the rail is required to properly defrost the rail.

The power must be turned to OFF and the unit
disconnected from the power source whenever
performing service or maintenance functions.
Never operate the unit without the louvered panel in
place!

All R404A models have a high pressure limiting device. Under
severe overloading conditions, or in the event of a condenser fan
failure or a plugged or blocked condenser, this device may shut
down the refrigeration system. This device will automatically reset,
but determining the cause of the high pressure condition should be
investigated by a qualified refrigeration technician.

Pressure Control Settings

The factory recommended low-pressure control settings
are: 55# cut-in and 30# cut-out to maintain proper

temperature for product in the rail. The interior temperature
is controlled by the thermostat mounted on the evaporator
coil housing.

Pressure Control

The temperature is controlled by an adjustable pressure
control located in the machine compartment. An adjustable
control has the word COLDER near the knob, with an arrow
to indicate the adjustment direction. These controls are field
adjustable and do not require a service agent.

In attempting to adjust the pressure control,
you can do damage to your unit by accidentally
adjusting the differential. Please make small
incremental adjustments if a temperature
adjustment is necessary, please contact the
service department at McCall [phone] or
your local service agent. McCall is not responsible
for charges incurred while having the pressure
control adjusted.
