4.4.2 Water-Cooled Condenser with Condenser
Fan Switch
a. Connect the water supply line to the inlet side of con-
denser and the discharge line to the outlet side of the
condenser. (See Figure 2-5.)
b. Maintain a flow rate of 11 to 26 lpm (3 to 7 gpm).
c. Set the condenser fan switch to position "O". This will
de-energize the condenser fan relay. The condenser
fan motor will stop and remain stopped until the CFS
switch is set to position "I."
CAUTION
When condenser water flow is below 11 lpm
(3 gpm) or when water-cooled operation is
not in use, the CFS switch MUST be set to
position "1" or the unit will not operate
properly.
d. To shift to air-cooled condenser operation, stop the
unit, set the CFS switch to position "I" and restart the
unit. Disconnect the water lines to the water-cooled
condenser.
4.5 CONNECT REMOTE MONITORING
RECEPTACLE
If remote monitoring is required, connect remote
monitor plug at unit receptacle. When the remote
monitor plug is connected to the remote monitoring
receptacle, the following remote circuits are energized:
CIRCUIT
Sockets B to A Energizes remote cool light
Sockets C to A Energizes remote defrost light
Sockets D to A Energizes remote in-range light

operating parameters. Refer to paragraph 3.2.2.

4.7.3 Start Temperature Recorder

Partlow Recorders
a. Open recorder door and wind mechanical clock or
check battery of electronic recorder. Be sure key is re-
turned to storage clip of mechanical recorder.
b. Lift stylus (pen) by pulling the marking tip outward un-
til the stylus arm snaps into it's retracted position.

2. Depress and hold the ENTER key for five seconds.
3. The "Trip Start" event will be entered in the Data-
CORDER.

4.7.4 Complete Inspection

Allow unit to run for 5 minutes to stabilize conditions and
perform a pre--trip diagnosis in accordance with the
following paragraph.

4.8 PRE-TRIP DIAGNOSIS

Pre-trip inspection should not be per-
formed with critical temperature cargoes in
the container.
When Pre-Trip key is pressed, dehumidifi-
cation and bulb mode will be deactivated.
At the completion of Pre-Trip activity, dehu-
midification and bulb mode must be reacti-
vated.
Pre-Trip diagnosis provides automatic testing of the unit
components using
comparison logic. The program will provide a "PASS" or
"FAIL" display to indicate test results.
The testing begins with access to a pre-trip selection
menu. The user may have the option of selecting one of
three automatic tests (depending on software revision
installed). These tests will automatically perform a
series of individual pre--trip tests. The user may also
scroll down to select any of the individual tests. The
contents of the menus are as follows:
