an inoperative Comp, or an inoperative HM. If the unit switches out of freeze with F/S connector removed, but would previously not switch out of freeze with F/S connected (long freeze - 3 beep alarm), F/S may be sticking. To check and clean F/S, see "IV.D.
Float Switch Check and Cleaning." If the unit remains in freeze longer than 15 seconds after disconnecting black F/S connector, replace CB.
Note: Normal freeze cycle will last 20 to 40 minutes depending on model and conditions. Cycle times and pressures should follow performance data provided in this manual. See "III.C. Performance Data."

S4 dip switch 3 & 4 to 3 off and 4 on. Adjustment to this position on this model prevents the pump motor from rotating in the
"II.C.2.c) Pump‑Out Timer (S4 dip switch 3 & 4)." Comp and FMR remain energized,
HGV energizes. WV energizes if S4 dip switch 3 off and 4 on. LLV and FM de‑energize. PM stops for 2 seconds, then reverses for 10/20 seconds depending on pump‑out timer S4 dip switch 3 & 4 setting. When the pump‑out timer terminates, the pump-
out is complete. The

Diagnosis: If PM does not reverse, check to see if CB S4 and S5 dip switch settings are in the factory default position. If S4 dip switch 3 and 4 are adjusted to 3 off and 4 on, WV and harvest pump timer relays energize. Once these relays energize, the pump motor rotates in the freeze cycle rotation. See "III.B. Wiring Diagrams." Check PM circuit and capacitor, check #5 pin (DBu wire) on CB
