IMPORTANT NOTE:
When changing an evaporator thermostat, make sure that at least 8" of capillary tube
is “S“ shaped and laying tight against the bracket soldered to the bottom of the evaporator. Tape at least 1"
of capillary tube to the hot gas line at the front edge of the evaporator. This shortens the defrost time.

NOTE:
Maximum ice production will only be obtained under ideal
conditions. Production capacities shown in the above graph are
average and variances are normal.
Additional factors which reduce the production capacity are:
1
. Making cubes thicker than 1/2”.
2
. Increased ice meltage in storage bin due to high ambient
To maintain production capacity, avoid locating icemaker in
greasy or dusty atmosphere, or adjacent to high temperature
equipment such as ovens, ranges, steam tables, etc. . .
