7) Pump-Out Cycle – LEDs 1, 3, and 2 are on (10/20 second pump-out). Timing of the
rst pump-out is determined by S4 dip switch 5& 6. See the table below.

Comp and FMR continue, HGV energizes. If S4dip switch 3 & 4 are set to 3 off
and 4 on, LED 4 turns on and WV and X11 relay energize, energizing X10relay.
NOTICE!S4dip switch 3 & 4 must not be set to 3 off and 4 on. Otherwise, PM
will rotate in freeze cycle direction instead of pump-out direction. FM and LLV
de-energize. PM stops for 2 sec., then reverses for 10/20 sec. depending on pump-out
timer (S4dip switch 3 & 4) setting. When the pump-out timer terminates, pump-out
is complete. The pump-out frequency control (S4 dip switch 5 & 6) is factory set, and
generally no adjustment is required. However, the pump-out frequency control can be
set to have a pump-out occur every cycle, or every 2, 5, or 10 cycles. For details, see
"III.C.4. Pump-Out Frequency Control (S4 dip switch 5 & 6)."
Pump-Out Diagnosis: In the freeze cycle before pump-out (see table above), after
5min. of freeze disconnect CB black K5 connector (FS connector). Check that PM
stops and re-starts and that PM rotation is correct (water owing down the drain through
CV). If PM does not stop and re-start, check that CB LEDs 1, 3, and 2 are on. If not,
replace CB. IfLEDs1,3, and 2 are on and PM does not energize, check for 115VAC
at CB K1 #5 (DBU) to neutral (W). If 115VAC is not present, replace CB. If 115VAC
is present, check that X10 relay is de-energized. If not, check X11 relay status. If X11
relay is energized, replace CB. If X11 relay is de-energized and X10 relay is energized,
replace X11 relay (contacts sticking). If X10 relay is de-energized, check for 115VAC
at terminal #6 (DBU) to neutral (W) and terminal #2 (DBU) to neutral (W). If 115VAC is
present on terminal #6 (DBU) and not on terminal #2 (DBU), replace X10 relay. If PM is
energized and rotating in pump-out rotation, make sure the drain line is not clogged and
that CV is clean and operating properly.
Conrm FM and LLV de-energize. If FM or LLV are energized with LEDs 1, 3, and 2 on,
replace CB.
