WARNING
Do all wiring with the electrical power
disconnected.
To install the KCMR230 fan relay kit when using
(2) 230 VOLT ice makers and one 230 volt, two
circuit remote condenser (ERC302).
See the remote condenser nameplate for current
requirements to determine wire size to be used for
electrical hookup. Refer to wiring diagram.
All external wiring should conform to the national,
state and local electrical codes. Usually an
electrical permit and services of a licensed
electrician will be required.
1. Mount the control box in a convenient location.
2. Attach a solid earth ground wire to the ground
screw.
3. Route connecting wires from the first ice maker
junction box
(marked condenser fan) and connect it to the
KCMR230 terminal strip marked: NO. 1 ICE
MACHINE.
4. Route connecting wires from the second
machine junction box
(marked condenser fan) and connect it to the
KCMR230 terminal strip marked: NO. 2 ICE
MACHINE.
5. Route connecting wires from KCMR230
terminal strip marked: TO REMOTE FAN and
connect at the remote condenser junction box.
6. Check phasing of the electrical circuit as
follows:
A. The phasing of the wiring MUST now be
checked, as incorrect phasing will result in a failure
of the kit relay.
Below is an illustration of the KCMR230 terminal
strip. Note that each terminal is marked:
1-2-3-4-5-6. For proper phasing:
Terminals #1 and #3 must be connected to the
same side of the line (such as L1)
Terminals #2 and #4 must be connected to the
same side of the line (such as L2).
B. Make a test with a volt meter as follows:
1. Switch on ice maker #1 first, then switch on ice
maker #2.
(The compressors must be operating for this test.
Do this after start up.)
2. Test with a volt meter between terminals #2 and
#4, then between terminals #1 and #3. Compare
the readings obtained to the ones in the following
list:
C. Test terminals 1-2 = Full Voltage (208-230)
Test terminals 1-3 = No voltage
Test terminals 2-3 = Full Voltage
Test terminals 2-4 = No voltage
Test terminals 3-4 = Full voltage
Test terminals 1-4 = Full voltage
D. If there is full voltage where there should be no
voltage, turn off ice maker #2, (both switches)
Then turn off ice maker #1 (both switches). The
connections at the KCMR230 terminal strip marked
ice maker #1 must be reversed (put the wire that
was on 1 on 2 and the wire that was on 2 on 1).
WARNING
Do all wiring with the electrical power
disconnected.
