2. Maintain a flow rate of 11 to 26 liters per minute (3 to 7 gallons per minute). The water pressure switch will
open to de-energize the condenser fan relay. The condenser fan motor will stop and will remain stopped
until the water pressure switch closes.
3. To shift to air-cooled condenser operation, disconnect the water supply and the discharge line to the water-
cooled condenser. The refrigeration unit will shift to air-cooled condenser operation when the water pressure
switch closes.
5.5.2
Water-Cooled Condenser with Condenser Fan Switch
1. Connect the water supply line to the inlet side of condenser and the discharge line to the outlet side of the
condenser (see
.)
2. Maintain a flow rate of 11 to 26 lpm (3 to 7 gpm).
3. 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.
4. To shift to air-cooled condenser operation, stop the unit, set the CFS switch to positioI” and restart the unit.
Disconnect the water lines to the water-cooled condenser.
5.6 Connect Remote Monitoring Receptacle
If remote monitoring is required, connect the remote monitor plug at the unit receptacle, see item 9,
When the remote monitor plug is connected to the remote monitoring receptacle, the following remote circuits are
energized:
5.7 Starting and Stopping Instructions
WARNING
!
Make sure that the unit circuit breaker(s) (CB-1 & CB-2) and the START-STOP switch (ST) are in
the “O” (OFF) position before connecting to any electrical power source.
NOTE
The electronic phase detection system will check for proper compressor rotation within the first 30 seconds.
If rotation is not correct, the compressor will be stopped and restarted in the opposite direction. If the com
-
pressor is producing unusually loud and continuous noise after the first 30 seconds of operation, stop the
unit and investigate.
5.7.1
Starting the Unit
1. With power properly applied, the fresh air vent set and (if required) the water-cooled condenser connected
,
), place the START-STOP switch to “I” (ON).
2. The Controller Function Codes for the container ID (Cd40), software version (Cd18) and unit model number
(Cd20) will be displayed in sequence.
3. Continue with Start Up Inspection (see
).
