Design & Function
IM MODULAR SEQUENCE OF OPERATION
INITIAL START-UP IM SERIES
1.
Move the ICE-OFF-CLEAN switch to the
“ICE”
position.
2.
Water inlet solenoid energizes and allows water trough to fill until water reaches the low-level sensor on the water sensor probe.
3.
Dump valve & water pump energize to discard the remaining water in the trough for 20 seconds after detecting the low-level sensor
on the water sensor probe.
4.
Water valve energizes and allows water trough to fill until water reaches the high-level sensor on the water sensor probe.
5.
Five seconds later, the hot gas valve energizes for 10-20 seconds to allow for pressure equalization and to reduce compressor
starting torque.
6.
The hot gas solenoid is de-energized once the compressor and condenser fan are energized for a 15 second evaporator pre-chill.
7.
The water pump is energized after the 15 second pre-chill, circulating water over the evaporator.
8.
The water inlet solenoid is energized and supplies additional water once water level sits below the low-level sensor.
(Happen in 1
st
cycle only.
From the second cycle onward, even if the low water level is detected, no additional water supplied
)
9.
Water circulates over evaporator for approximately 10 minutes.
10. When water contacts the ice thickness probe for 7 continuous seconds, the machine enters the defrost cycle (
Harvest
).
11. With compressor running, the hot gas valve is energized for approximately 1.5 minutes or until the ice is harvested.
12.
The defrost cycle is terminated when ice drops from the evaporator and causes the bin switch to open and close.
13. If the ice bin level is sufficiently high enough that ice is trapped between curtain and evaporator, the machine stops operation and
the
“Full Lamp”
on front of machine is lit.
