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.
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.
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.
(2) Cabinet still cooling, rail cool down achieved
RailFM continues (RailFM continues when rail switch is in the "NORMAL"
position and per F9 setting when in the "LOW" position), RLLV and DH 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.

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.
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.
