[G] Water Supply Control; [H] Ambient Temperature Correction; [I] Dimple Diameter Setting - Hoshizaki DIM-40DE-HC Service Manual

[g] WATER SUPPLY CONTROL

1) When the water pan closes and the hall IC turns on, the water valve opens to supply
icemaking water for a specific time. The icemaking water supply time varies between
startup, reset, and the end of bin control cycle.
* The icemaking water supply time and additional water supply time are adjustable
in the maintenance mode (see "3. [b] MAINTENANCE MODE").
2) After the water pan starts to open, the water valve opens in 20 seconds to supply
defrosting water (water pan cleaning water) for a specific time. The defrosting water
supply time varies between the water temperatures above and below 13°C. If the
water temperature is below 13°C, the water valve opens for 10 seconds after the
water pan starts to close.
* The defrosting water supply time is adjustable in the maintenance mode (see "3. [b]
MAINTENANCE MODE").
3) The water temperature is determined by a predetermined offset value plus the cube
control thermistor temperature after icemaking water is supplied as mentioned in 1)
and the pump motor runs for 30 seconds.
* The water temperature offset value is adjustable in the maintenance mode (see "3.
[b] MAINTENANCE MODE").

[h] AMBIENT TEMPERATURE CORRECTION

1) At low ambient temperatures, the dimple diameter of ice cubes is increased by a
predetermined rate between the ambient temperature and target integrated freeze
completion value to prevent reduction in the evaporator temperature leading to
excessive ice production.
* The rate between the ambient temperature and integrated value is
the maintenance mode (see "3. [b] MAINTENANCE MODE").

[i] DIMPLE DIAMETER SETTING

1) To adjust dimple setting (see "3. [b] MAINTENANCE MODE") (maintenance mode
No. 2 and 3).
2) Maintenance mode 2 set point temperature can go up or down in 0.5°C increments.
3) Maintenance mode 3 set point temperature can go up or down in 1min increments.
4) When the switches are not pressed for 30 seconds, the set points are determined
with "on" in the display.
