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 icemaker #1 first, then switch on
icemaker #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 icemaker #2, (both
switches) Then turn off icemaker #1 (both
switches). The connections at the KCMR230
terminal strip marked icemaker #1 must be
reversed (put the wire that was on 1 on 2 and
the wire that was on 2 on 1).
