a) Cabinet Defrost: Power Switch "ON," Rail Cooling Switch "OFF"

CLLV continues, CabFM, Comp, ConFM, and PH de-energize. DH energizes and

warms DTh to 49°F (9.4°C) (or the 100-minute defrost termination timer expires

or DTst warms to 120°F±5°F (49°C±3°C)). When DTh reaches 49°F (9.4°C),

DH de-energizes, CLLV continues and a 5 minute Comp delay timer starts. When the

5-minute Comp delay timer expires, CabFM and PH energize for 10 seconds. Comp

and ConFM then energize and a 5-minute CabFM and PH delay timer starts. After the

5-minute CabFM and PH delay timer expires, CabFM and PH energize.

b) Cabinet Defrost: Power Switch "ON," Rail Cooling Switch "NORMAL" or "LOW"

(1) Cabinet cool down achieved, rail still cooling

Comp, CondFM, RailFM, and RLLV continue. CabFM and PH de-energize, and

CLLV remains de-energized. DH energizes and warms DTh to 49°F (9.4°C) (or

the 100-minute defrost termination timer expires or the DTst warms to 120°F±5°F

(49°C±3°C)). When DTh reaches 49°F (9.4°C), DH de-energizes, Comp, ConFM,

RailFM, and RLLV continue. CabFM and PH energize for 10 seconds. CLLV then

energizes and a 5-minute CabFM and PH delay timer starts. After the 5-minute

CabFM and PH delay timer expires, CabFM and PH energize.

CabFM, Comp, ConFM, and PH de-energize. CLLV de-energizes for 2 seconds,

then energizes again. DH warms DTh to 49°F (9.4°C) (or the 100-minute

defrost termination timer expires or the DTst warms to 120°F±5°F (49°C±3°C)).

When DTh reaches 49°F (9.4°C), DH de-energizes, RailFM continues, RLLV

de-energizes, CLLV energizes, and a 5-minute Comp delay timer starts. When the

5-minute Comp delay timer expires, CLLV and RailFM continue. CabFM and PH

energize for 10 seconds. Comp and ConFM then energize and a 5-minute CabFM

and PH delay timer starts. After the 5-minute CabFM and PH delay timer expires,

CabFM and PH energize.

6. Rail Defrost

For rail defrost (manual defrost), remove product from the rail area and store in a

properlyrefrigeratedarea,thenmovetherailcoolingswitchtothe"OFF"position.
