Remote condenser and other maintenance
The condenser fins will need to be cleaned.
Push and release the Off button. Wait until the
machine stops.
Note: Lock out the controller or the ice machine
power supply to prevent an unauthorized fan
motor restart.
If there is imbedded grease, use a commercial coil
cleaner to wash out the grease. Dust can be blown
out with compressed air from the inside or use a
vacuum cleaner and soft brush. Be careful not to
damage the condenser’s fins. Use a fin comb to
straighten any bent fins.
Exterior Panels
The front and side panels are durable stainless steel.
Fingerprints, dust and grease will require cleaning
with a good quality stainless steel cleaner.
Water Level Sensor
The water sensor probes and probe housing must be
cleaned regularly.
Locate water level sensor. Squeeze catches together
and pull up to remove sensor. Unplug from harness.
Separate probes from housing and wash all surfaces
with ice machine scale remover solution.
Note: Be sure white holder is clean.
Return probes to holder.
Technical Highlights
• 3 Evaporators
• 3 Thermostatic Expansion Valves
• 3 Harvest Assist Solenoids
• 3 Hot Gas Valves
• 1 OPR valve
Ice making or the freeze cycle is controlled by an ice thickness sensor on the far left evaporator.
When the ice is the correct size the controller switches the machine to a harvest cycle.
All three hot gas valves open at the same time.
Harvest continues until all 3 curtains have opened. After all 3 curtains have opened and re-closed, the freeze
cycle restarts.
If one or more of the curtains stay open for 30 seconds or longer, the controller switches the machine off
(closes the liquid line solenoid valve then shuts the compressor off) and signals bin full. It will restart ice
making when all three curtains are closed.
The OPR valve is set to limit dome pressure during harvest to 80 PSIG.
The optional KVS (Vari-Smart) sensor location is in the base behind the compressor.
Release probes by pushing in on white buttons and
pulling probe down out of holder.
