NOTE: Refer to Figure 4.

1. Attach the Quick Exhaust Valve (Item 23) to the brake.

Use Teflon tape and/or pipe sealant on the threads. If
you are using the optional Solenoid Valve (Item 12) in
conjunction with the Quick Exhaust Valve, assemble
the Solenoid Valve to the Quick Exhaust Valve. Using
the two valves in conjunction with each other will
decrease the brake disengagement time.

2. If you are using the optional Solenoid Valve (Item 12) in

place of the Quick Exhaust Valve (Item 23), assemble
the optional Solenoid Valve directly to the brake using
the supplied fittings. Use Teflon tape and/or pipe
sealant on the threads. The fitting for the air line itself
is O-ring sealed and does not require tape or sealant.

CAUTION: The brake will disengage if you depress the

brass button on the Solenoid Valve (if air pressure is

supplied). The LED will illuminate when the Solenoid

Valve is actuated and the brake is disengaged.

Pressure needed to disengage should NOT exceed

80 psi.

NOTE: Align the air inlet port in the down position to allow
condensation to drain out of the air chamber.

3. Attach the air supply line to the valve.

4. 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
Table 1.
