Freeze Termination Diagnosis:
After 5 min. in freeze, disconnect CB K5 FS
connector. 15 sec. later appliance should switch out of the freeze cycle (15 second
delay after FS opens before terminating the freeze cycle). If appliance remains in
freeze longer than 15 sec. after FS removed, replace CB. If appliance switches with
FS removed but would previously not switch out of freeze with FS connected (long
freeze - 3 beep alarm), see "II.F. Float Switch Check and Cleaning."
Note: Normal freeze cycle will last 20 to 40 min. depending on model and conditions.
Cycle times and pressures should follow performance data provided in this manual.
See "VIII.A. Specification and Performance Data Sheets."
h)
Short Freeze Cycle Diagnosis
: Confirm water tank fills and overflows during 1 min.
fill and harvest cycles. If not, check water supply filters, shut-off valve, WV screen.
If water tank empties before 5 min. timer terminates and freeze cycle is short, check
that DV is not leaking by or energized (water flowing through DV). If DV is leaking by,
remove and clean DV, replace as needed. If water tank is full, see "II.F. Float Switch
Check and Cleaning." for erratic operating FS.

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

After 2nd freeze cycle
Comp and FMRs continue, HGVs energize.
Note: If S4 dip switch 3 & 4 are set to 3 off and 4 on, LED 4 turns on and WV and X11
relay energize, energizing X10 relay.
NOTICE!
S4 dip switch 3 & 4 must not be set
to 3 off and 4 on. Otherwise, LED 4 turns on energizing WV and X11 relay. X11
relay energizes X10 relay. Once X10 relay energizes, X12 relay cannot energize.
Preventing DV from energizes.
LLVs de-energize. PM stops for 2 sec., then restarts for 10/20 sec. depending on
pump-out timer (S4 dip switch 3 & 4) setting. When the pump-out timer terminates,
pump-out is complete. The pump-out frequency control (S4 dip switch 5) 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 10 cycles or every cycle. For details, see "III.C.4.
Pump-Out Frequency Control (S4 dip switch 5)."
a)
Pump-Out Diagnosis
: In the freeze cycle before pump-out (see table above), after
5 min. of freeze disconnect CB black K5 connector (FS connector). Check that CB
LEDs 1, 3, and 2 are on, PM stops, then restarts, DV energizes, and water is flowing
down the drain through DV.
