B. Functions

1. Increasing Rinse Water Flow Rate

The rinse water flow rate is factory adjusted to 1.90 gal/min (7.2 L/min). To increase the flow rate to 3.17 gal/min (12 L/ min), follow the steps below. Hot water supply of at least 3.44 gal/min (13 L/min) and 113°F (45°C) will be required.

Upper Rinse Spray Arm

Clean Pipe

Lower Rinse	Nut
Spray Arm

1)	Remove the upper and lower rinse spray arms.	Spacer
2)	Loosen the clean pipe nut, and remove the clean pipe.

3)Remove the spacer (with 4.5 mm DIA hole) from the nut at the unit side.

4)Replace the clean pipe and the upper and lower rinse spray arms in their correct positions.

C. Sequence of Operation

The steps in the sequence are as outlined below.

1. Auto Fill Cycle

"AUTO FILL" lamp flashing and "RINSE TEMP." or "WASH TEMP." lamp on.

If BT WLF/S is open when the "ON/OFF" button is pressed, WV energizes after BT auto fill delay time (factory default: 10 seconds).

When BT WLF/S closes, WV de-energizes, the "AUTO FILL" lamp flashes and the auto fill cycle starts.

RPM energizes for length of time set by the auto fill cycle rinse time setting (factory default: 13 minutes). For details, see "Auto Fill Cycle Rinse Time" (service menu item 03) in "II.F.7.b) Service Menu Chart."

At the end of the auto fill cycle, there is a 5-second dwell time. CB checks WT WLS. If WT WLS is closed, BZ beeps, the "AUTO FILL" lamp goes off and the "READY" lamp comes on. If WT WLS is open, BZ beeps continuously, the "AUTO FILL" lamp goes off and "A1" flashes in the display. For details, see "III.B.3.a) Auto Fill Error (A1)."

If the BT water level goes down and BT WLF/S opens during the auto fill cycle, WV energizes after BT auto fill delay time (factory default: 10 seconds). For adjustment of this delay time, see "Booster Tank Auto Fill Delay Time" (service menu item 08) in "II.F.7.b) Service Menu Chart." If delay time is set shorter, WV energizes/de-energizes frequently and BT may not supply hot water of proper temperature.

If SP is opened during the auto fill cycle, SPS opens, RPM de-energizes. The "AUTO FILL" lamp keeps flashing and the rinse cycle time keeps counting down. When SPS closes again, RPM energizes.

If WLS is closed when the "ON/OFF" button is pressed, the "READY" lamp comes on and the unit is ready to start.

Note:

1.If SP is opened during the auto fill cycle, RPM de-energizes to stop hot water supply. If SP is left open for a long time, WT may not fill by the end of the auto fill cycle. In this case, WT WLS opens when the unit starts, and the supplementary fill cycle begins.

2.WTH is energized when WT WLS closes during the auto fill cycle.

3.BTH is energized during the auto fill cycle if WLSF/S is closed.
