McCall Series II Reach-Ins with ABS Interior Service and Installation Manual

Installation

Location

Units represented in this manual 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
McCall reach-in can weigh as much as 1500 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. The refrigerated air is discharged at the top rear of
the unit. It is important to allow for proper air flow from the
top rear to the bottom of the unit. Obstructions to this air flow
can cause evaporator coil freeze ups and loss of temperature
or overflow of water from the evaporator drain pan. The rear
of the unit has molded ribs and the shelves have a rear turn
up on them to prevent this. However, bags and other items
can still be located to the far rear of the cabinet. There is also
a return air diffuser along the top front of the cabinet interior,
this also requires proper air circulation. Prevent obstruction by
locating large boxes and tall stacks of product to the bottom of
the cabinet.

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
2” from any wall with at least 12” of clear space above the
unit. Avoid exposing glass door units to direct sunlight. Direct
sunlight through the glass doors will make the ABS liner
fade and become brittle and will greatly reduce refrigeration
efficiency.

Leveling

A level cabinet looks better and will perform better because the
doors will line up with the frames properly, the cabinet will not
be subject to undue strain and the contents of the cabinet will
not move around on the shelves. Use a level to make sure the
unit is level from front to back and side to side. Units supplied
with legs will have adjustable bullet feet to make the necessary
adjustments. If the unit is supplied with casters, no adjustments
are available. Ensure the floor where the unit is to be located is
level.

Stabilizing

Some models are supplied on casters for your convenience,
ease of cleaning underneath and for mobility. It is very
important, however, that the cabinet be installed in a stable
condition with the front wheels locked while in use.
Should it become necessary to lay the unit on its side or back for
any reason, allow at least 24 hours before start-up so as to allow
compressor oil to flow back to the sump. Failure to meet this
requirement can cause compressor failure and unit damage.

Unit repairs will not be subject to standard unit
warranties due to improper installation procedures.

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 thermostat must be turned to OFF and
the unit disconnected from the power source
whenever performing service, maintenance
functions or cleaning the refrigerated area.

McCall Series II Reach-Ins with ABS Interior Service and Installation Manual

Operation

The electronic temperature control constantly monitors box
temperature as well as evaporator coil temperature to maintain
consistent product temperatures. The control also sends temperature
readings to the digital temperature display. The control circuits
continually self-check and if an error occurs, the digital display will
switch from temperature read-out to error read-out, i.e. E 1. Even
when an error is displayed, the refrigeration and controls system
should continue to function, however not at optimal performance.
Whenever the display has an error read-out, McCall Service should
be contacted.

At initial start-up or anytime power is disconnected, then reconnected
to the unit, the control will delay all operations for a short time (up
to 10 minutes.) While in this delay period, the control initializes
the control parameters and confirms that the temperature sensors
and circuits are operational. The digital temperature display will not
display temperature OR errors until the self-check is complete and
the control has switched on the evaporator fan motor, compressor
and condenser fan motor.

IMPORTANT NOTE REGARDING FREEZERS: After initializing, the
control will immediately enter a DEFROST mode and the display
will read DEF. The compressor and condenser fan as well as the
evaporator fan will remain off until initialization defrost is complete.
This initial defrost cycle may take up to 15 minutes to complete,
at which time the freezing cycle will begin. The display will
continue to read DEF for an additional 30 minutes before displaying
temperature.

Refrigerator:

The control is located in the control box in the top of the refrigerator
behind the removable louvered panel on the left side. It is factory
set at mid-range to maintain about 38˚F (3˚C) box temperature. To
adjust for colder temperatures, turn the knob clockwise. For warmer
temperatures, turn the knob counter-clockwise. Turn the knob fully
counter-clockwise to turn the refrigeration system off. Never turn
the knob more than 1 dial number and always allow 8 hours for
temperature stabilization before making any additional adjustments.

Freezer:

The control is located in the control box in the top of the refrigerator
behind the removable louvered panel on the left side. It is factory
set at mid-range to maintain about -3˚F (-18˚C) box temperature. To
adjust for colder temperatures, turn the knob clockwise. For warmer
temperatures, turn the knob counter-clockwise. Turn the knob fully
counter-clockwise to turn the refrigeration system off. Never turn
the knob more than 1 dial number and always allow 8 hours for
temperature stabilization before making any additional adjustments.

Energy Saver Switch

The energy saver switch is a rocker switch located next to the
thermostat knob. The normal operating position for this switch is
the OFF or “0” position. If excessive condensation is observed on the
door opening, flip the energy saver switch to the ON or “-” position,
(red portion of the rocker switch will be visible).

Refrigerator

Whenever the refrigerator is plugged in, and the control has
completed initializing, the evaporator fans will run continuously and
the digital temperature will display box temperature in degrees F. The
temperature control will cycle the compressor and condenser fan
motor to maintain box temperature at the control setting.

Refrigerator Defrost

The temperature control also monitors the evaporator temperature
and will turn off the compressor and condenser fan motor when
needed to allow accumulated frost on the evaporator to clear. During
this defrost cycle, the digital temperature display will read dEF. After
the defrost cycle is complete, the temperature control will return to a
normal cooling cycle, but the display will continue to read dEF until
the evaporator returns to normal cooling temperatures (up to 30
minutes).

Freezer:

Whenever the freezer is plugged in, and the control has completed
initializing including the initial defrost cycle (also see Electronic
Temperature Control Operation, on this page), the evaporator fans
will run continuously. After evaporator coil has reached operational
temperature, the digital temperature will display box temperature in
degrees F. The temperature control will cycle the compressor and
condenser fan motor to maintain box temperature at the control
setting.

Freezer Automatic Defrost

The control also monitors compressor total running time and will
enter a defrost cycle after total compressor running time is greater
than 4-hours since the last defrost cycle OR if evaporator coil
temperature drops below -34˚F (indicating excessive frost on the
coil).

Freezer Manual Defrost

If a manual defrost is desired, simply unplug the unit for several
seconds, then plug unit back in. This will cause the control to re­initialize and then enter a defrost cycle.

When the control enters the defrost mode, it switches off the
evaporator fan motor, compressor and condenser fan motor, and
switches on the defrost heater to warm the evaporator coil. Thereby
melting all frost accumulated during the previous refrigeration
cycle. The digital temperature display will now read dEF. The
control will continue the defrost cycle for a MINIMUM of 8 minutes
and a MAXIMUM of 30 minutes depending on the amount of frost
accumulated on the evaporator coil.

After the defrost cycle is complete, the control returns to a normal
refrigeration cycle, however the evaporator fan motor will not switch
on for 2 minutes AFTER the compressor and condenser fan motor
have begun operating. The digital temperature display will continue
to read dEF until the evaporator has returned to normal freezing
temperatures (up to 30 minutes).
