ELEVATION SERIES CIM CUBER WATER PUMP
38
Water Pump
Operation
Relay 6 on the Board (LED ON) energizes the
Water Pump after the 30 second Pre-Chill of
the Evaporator during the Freeze Cycle. In the
first 3 Freeze Cycles after a shutdown (turned
OFF or Bin Full) the Water Pump will perform
a shutdown for 20 seconds to help prevent
the Sump from slushing. The Water Pump will
then be energized to complete the Freeze
Cycle (see Sequence of Operations pg. 9) The
Water Pump is active continuously during the
Cleaning Cycle after the Sump is filled (see
Cleaning Instructions pg. 56).
Troubleshooting
If Relay 6 LED is ON but the Water Pump does not run, verify line voltage between the Yellow
and Blue wires on the Molex. If line voltage isn’t found, verify connection of Molex to Board and
re-verify. If no voltage is found, the issue is the Board. If line voltage is found, verify line voltage
at Water Pump connector. If no voltage found, the issue is the wiring or connectors. If line Volt-
age is found, but Water Pump won’t spin, the issue is the Water Pump. Clean or replace as
required.
When verifying voltage out of Board, check at the Blue and Yellow wires.
Voltage can also be checked at the connector at the Water Pump.
