'' Q
a) Internal Booster Tank Energy Saving Mode
The internal booster tank energy saving mode allows the internal booster tank temperature
to drop during periods of inactivity. To activate or deactivate the internal booster tank energy
saving mode, see " Internal Booster Tank Energy Saving Mode" (service menu item 14) in
"II.D.7.b) Service Menu Chart."
After a period of inactivity from 0 to 99 minutes (service menu item 16), the temperature
to maintain is dropped to the setpoint minus 0°F to 40°F (0°C to 22°C) (service menu item
15).
Adjust the water temperature drop so that the rinse (internal booster tank) water temperature
rises enough to be at least 180°F (82°C) after the wash cycle.
The minimum rinse (internal booster tank) water temperature for the unit to switch out of the
wash cycle and into the rinse cycle can be set from 180°F to 185°F (82°C to 85°C) (service
menu item 17). If the minimum temperature has not been reached at the end of the preset
wash cycle time (service menu item 01 or 02), the wash cycle is extended up to 60 seconds
until the temperature is reached. If the temperature is not reached in 60 seconds, the unit
goes into ready mode. This setting only applies when the energy saving mode is activated.
Note:
The default water temperature drop of setpoint minus 15°F (8°C) was based on test results
under the following conditions:
Supply Voltage: 230V
Water Supply Temperature 109°F (43°C)
Rinse Cycle Time: 6 seconds (0.53 gal/rack)
Dwell Time: 5 seconds
Ambient Temperature: 77°F (25°C)
b) Continuous Wash Mode
The continuous wash mode (also used when descaling) allows the wash pump motor to run
continuously. In this mode, the wash tank heaters and internal booster tank heaters remain
de-energized.
To enter the continuous wash mode, use the "ON/OFF" button to turn off the unit. Press and
hold the up and down buttons and the "MODE" button for 3 seconds and press the "ON/OFF"
button. As long as the door switch and wash tank water level sensor are closed, the wash
pump motor runs
and power is supplied to the detergent feeder terminals. "PC" (preventative
cleaning) appears in the display and the lamps are off.
To cancel the continuous wash mode, press the "ON/OFF" button.
c) Consecutive Rinse Mode
The consecutive rinse mode (also used in self-cleaning) allows the unit to run through
5 consecutive rinse cycles.
To enter the consecutive rinse mode, use the "ON/OFF" button to turn off the unit. With the
door switch closed, press and hold the "STANDBY/CLEANING" button for 3 seconds. "SC"
(self cleaning) appears in the display and the "RINSE" lamp is on.
After running through 5 consecutive cycles, the buzzer beeps, then the unit turns off.
