START-UP AND CHECK-OFF
1.
Start the unrt by opening water valve and turning the
service switch to “ON ”
2.
NOTE:
In “CLEAN” positron, only the water pump

HOW IT WORKS
WITH SERVICE SWITCH IN “ON” POSITION
1.
Contactor IS energized
2. Compressor runs
3. Check water level In pump pan. When not running,
water level should be 11/4” deep.
4. Check for even water flow over freezrng plate. Unit
must be level for proper operation.
5. Check freezrng plate to make sure It
IS
getting cold.
3. Condenser fans run
4. Water pump runs
5. Thickness control
motor
runs
6. Cutter grid warm to touch
6. Check cutter grids. Interior temperature limiter above
NOTE:
Grids will be “OFF” until temperature limiter
top grid turns grids “OFF” above 130” F.

7. Check for desired cube thrckness and adjust if neces-
sary. Maximum capacity
will
be obtarned with Ice thrck-
ness at l/2” to 5/8”. Do not adjust less than 3/8” thick as
machine may malfunction.
8. Replace all panels
WHEN DESIRED ICE SLAB THICKNESS IS
REACHED, HARVEST CYCLE BEGINS WITH THE
FOLLOWING RESULTS:

HOW IT WORKS-MALFUNCTION LIGHT
1. When the high side pressure raises above the safe
operating lrmits the machine will shut down because the
blocked condenser thermostat or pressure
Control
opened and the light will come on.
On air cooled models-this indicates that the condenser
is blocked with dirt and must be cleaned or the con-
denser fan motor is not moving air through the finned
condenser.
On water cooled models - this indicates the condenser
has excessive scale inside, water pressure is low, or
water has been shut off.
NOTE:
After correcting the malfunction, manually reset
the control.
