PART #| Description
22699903| 15ft harness for power, fan, defrost heater
22699902| 25ft harness for power, fan, defrost heater
22699901| 40ft harness for power, fan, defrost heater
Note:
For systems with defrost heater load higher than 30 Amp, external contactors
are required to power the defrost heaters. The defrost heaters relay on the
intelliGen controller use as pilot relay for the external contactors.
Conduit runs for field wires
Field wires between the intelliGen controller and the unit cooler should be in
conduits and meet local building and electric code requirements. Conduit
fittings are also needed based on installation application. A site survey and
installation planning is recommended to determine conduit lengths and the type
of conduit fittings and quantity needed. It is required to run power wires and
low voltage (sensors and communication) wires in separate conduits.
Wire Protection
High voltage and low voltages wires inside the iFM kit requires additional
insulation protection. Wire sheathing should cover all wiring within the iFM
enclosure. Sets of wire sheathing are provided with the iFM kit. High voltage
wires may share a sheath, and low voltage wires may share a sheath, but each
group should be separately sheathed to maintain separation.
Unit Cooler Product Families Supported
The iFM Kit is designed to universal fit for Heatcraft’s Unit Coolers and other manufacturer’s Unit Coolers also.

-
Remove the existing mechanical expansion valve (TXV) in the distributor end of the unit cooler and replace with a new electronic expansion valve (EXV)
a.) Cut and remove the TXV from the copper pipes. -
See Pages 18 to 21 for instructions of installing new transformer, terminal board, temperature sensors, pressure transducer and EXV.
-
Wiring to solenoid valve (if needed by application)
f) Disconnect the existing wires terminated on the solenoid valve
g) Connect the two wires from the iFM controller to the solenoid valve
Check-Out Installation
After the installation has been completed, the following points should be covered before the system is placed in operation:
(a) Check all electrical and refrigerant connections. Be sure they are all
correct and tight.
(b) Check voltage taps on transformer at the evaporators for proper supply
voltage connection if a multitap transformer is used.
(c) Check high and low pressure controls, pressure regulating valves, oil
pressure safety controls, and all other safety controls and adjust them, if
necessary.
(d) On freezers only, check the low pressure switch setting. It must be set to
0 PSIG cut out, 10 PSIG cut in, to allow start and operation, especially in
cold ambients. Applies to special intelliGen condensing units only.
(e) Suction and liquid lines should always be insulated.
(f) Wiring diagrams, instruction bulletins, etc. attached to the condensing
units should be read and filed for future reference.
(g) All fan motors on air cooled condensers, evaporators, etc. should be
checked for proper rotation.
Fan motor mounts should be carefully checked for tightness and proper
alignment.
(h) Observe system pressures during charging and initial operation. Do not add
oil while the system is short of refrigerant unless oil level is dangerously
low.
(i) Continue charging until system has sufficient refrigerant for proper
operation. Do not overcharge.
Remember that bubbles in a sight glass may be caused by a restriction as well
as a shortage of refrigerant.
CAUTION: Extreme care must be taken in starting compressors for the first
time after system charging. At this time, all of the oil and most of the
refrigerant might be in the compressor creating a condition which could cause
compressor damage due to slugging. Activating the crankcase heater for 24
hours prior to start-up is recommended. If no crankcase heater is present,
then directing a 500 watt heat lamp or other safe heat source on the lower
shell of the compressor for approximately thirty minutes will be beneficial in
eliminating this condition which might never reoccur.
Initial Power On
When power supply is connected to the iRC for the first time, a series of
inputs is required to identify specific system parameters. Since there are no
factory set-point defaults pre-setup, the Quick Set-up procedure is triggered
to capture essential information about the system when the system is first
energized. This also occurs when a new iRC board is installed on a single
evaporator system.
Inputs for the Quick Set-up are made using the iRC user interface (UI)
control. The Control Knob on the iRC UI is used to navigate through the
required steps and to identify selections. Turning the knob will navigate
through possible selections for that particular
parameter. Pressing the Control Knob makes selections (similar to an Enter key
on a PC).
System Start-up
When the system is initiated for the first time, the compressor and the
electric defrost evaporator fans will be in a hold-off cycle and will not
start unless the hold-off cycle is complete. The electric expansion valve
(EXV) then opens to 50% and will begin its superheat control sequence. The
compressor starts and will be in a “hold-on” cycle. (This is to minimize
short-cycling of the system).
At initial start-up, the system may cycle off after a few minutes and display
a low superheat error, then restart itself. This cycle may be repeated a few
times. Do not shut the system off. Let the system run, as it may take a few
cycles for the electric expansion valve to attain the correct setting for the
set superheat.
Do not leave the unit unattended until the system has reached normal operating
conditions with the box pulled down to design conditions and the oil charge
has been properly adjusted to maintain the oil level at the center of the
sight glass.
When the room thermostat setting is satisfied (which may take a considerable
amount of time on “hot-box” pulldown), and if the compressor has run for a
minimum time for the “hold-on” cycle, the EXV will close (shutting off the
refrigerant flow to the evaporator), and the system will pumpdown and shut
off. The evaporator fans will continue to run.
Call for Cooling Start-up Operation
When the box temperature sensor detects a rise of approximately half the
box temperature differential, and the system has been off a minimum of the
hold-off cycle time, the EXV will open to its last position, and the
compressor will start. The EXV is then adjusted as necessary to obtain and
maintain the superheat setting. During this time, the compressor will run for
a minimum of the “hold-on” cycle time.
