5.6.2 Disconnecting the Pneumatic, Electrical, and Fluid Connections
WARNING!
Protect the solenoid valve and other non-wetted parts from contact with fluid. Do
not immerse in solvent.
To disconnect the pneumatic, electrical, and fluid connections (Figure 5-4):
1. Depressurize the SC-450, see 5.6.1 Depressurizing the SC-450.
2. Perform a service shutdown. Refer to the applicable coating system Installation,
Operations, and Maintenance Manual.
3. For the SL-940:
a. Disconnect the valve solenoid cable from the SC-450 to the V2 position.
b. Disconnect fluid line (red tubing) from the fluid fitting and place the fluid line over the
purge cup for residual fluid.
?
NOTE
If only the SC-450 is to be removed, seal the fluid system immediately using the
appropriate cap or plug. Plugging the fluid lines prevents fluid curing due to air
exposure.
c. Disconnect Valve air from the Valve air connection on the dispense head.
4. For the SL-1040:
a. Disconnect the valve solenoid cable from the SC-450 to the valve connection on the
dispense head.
b. Disconnect fluid line (black tubing) from the fluid fitting and place the fluid line over the
purge cup for residual fluid.
?
NOTE
If only the SC-450 is to be removed, seal the fluid system immediately using the
appropriate cap or plug. Plugging the fluid lines prevents fluid curing due to air
exposure.
c. Disconnect Valve air from the Valve air connection on the dispense head.
