7. Standard Configuration:
Attach the Quick Exhaust Valve (Item 23) to the brake.
Use Teflon tape and/or pipe sealant on the threads.
With Optional Solenoid:
If you are using the optional Solenoid Valve
(Nexen Part #964650), the Quick Exhaust Valve is
unnecessary. Assemble the optional Solenoid Valve
directly to the brake using the supplied fittings. Use
Teflon tape and/or pipe sealant on the threads.
NOTE: Align the air inlet ports in the down position
to allow condensation to drain out of the air
chamber.

9. If using optional solenoid valve, attach DIN Connector
cable to valve by pressing DIN Connector onto valve
power pins and tightening DIN Connector fastener.
Then connect DIN Connector cable wires using the
following chart to the appropriate power supply, see
