This procedure is affected by the current power consumption and utilization of the system. Be
cautious of workload increases or decreases. Significant workflow changes that occur after the
system is in manual mode could lead to cabinet EPO and/or condensation.
Procedure
1. Reconnect the water valve actuator control cable to the coil control board and wait until it has finished
actuating.
2. Verify the actuator is aligned properly. If the actuator is unaligned or is disassembled, use the following steps
to realign the actuator.
a. Position the metal ring on the actuator. The ring only fits on the actuator in the correct orientation.
b. Firmly pull on the water valve actuator handle to disconnect the handle from the actuator.
c. Place the actuator shaft in the opening. The shaft only fits in the correct orientation.
d. Pull the connecting screw slightly out of the shaft to aid in aligning the shaft in the actuator. Once the
shaft is fully inserted, reinstall the hex-head screw.
e. Remove the tape covering the actuator indicator dial.
3. If removed, position the handle on the actuator and push firmly to seat the handle.
4. Replace the tie straps that secure the control cables.
5.
CAUTION:
●
Equipment damage
●
The system must change from manual mode back to automatic mode. Failure to change the
system back to manual mode can result in equipment damage.
Implement the following command in the SMW to reactive HSS dynamic control (automatic mode):
smw$
echo 1 > temp_close_loop
6. Close the rear door of the cabinet.
