(3) Both CTh and RTh reach 3.6°F (2°C) below setpoint

CabFM and PH continue. RailFM continues when rail cooling switch is in the

"NORMAL"positionandperF9settingwheninthe"LOW"position.Fordetails,

de-energizes for 2 seconds. RLLV energizes, then remains energized during

Comp off time.

4. Cool Down Restart

a) Power Switch "ON," Rail Cooling Switch "OFF"

CTh warms to setpoint, the CabFM, CLLV, and PH continue. 2 minute Comp delay

timer starts. After the 2 minute delay timer expires, Comp and ConFM energize.

Cycle continues until power is turned off, the 6 hour DT expires and CB initiates

acabinetdefrost,orthe"MANUALDEFROST"buttonispressedfor5seconds

(evaporator temperature must be below 49°F (9.4°C)).

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

CTh, RTh, or both have warmed to setpoint.

(1) CTh at or above setpoint, RTh warms to setpoint

CabFM, Comp, ConFM, CLLV, PH, continue. RailFM continues when rail switch is

inthe"NORMAL"positionandresumescontinuousoperationwheninthe"LOW"

position. RLLV energizes.

(2) CTh warms to setpoint, RTh at or above setpoint

CabFM, Comp, ConFM, PH, RailFM, and RLLV continue. CLLV energizes.

(3) CTh or RTh warms to setpoint

RLLV continue. The 2 minute Comp delay timer starts. If CTh has warmed to

setpoint and RTh has not, CLLV energizes and RLLV de-energizes. If RTh

has warmed to setpoint and CTh has not, RLLV continues and CLLV remains

de-energized. After the 2 minute Comp delay timer expires, Comp and ConFM

energize.

5. Cabinet Defrost

The rst cabinet defrost occurs 6 hours after the unit is turned on. Cabinet defrost is

initiatedwhenthe6hourDTexpiresorthe"MANUALDEFROST"buttonispressed

for 5 seconds. Cabinet defrost termination occurs when the evaporator temperature

reaches 49°F (9.4°C). Note that the defrost is a heated defrost, and therefore will have a

tendency to raise the cabinet temperature. Cabinet temperature is not displayed during

defrost;"dF"isdisplayedinitsplace.Afterdefrost,thereisa5minutedelaybeforethe
