Install the ECU/Relay Valve and Stand Alone

Relay Valve

In all installations, the ECU/Relay Valve assembly appears

as Relay Valve “A” in the diagrams. The Stand Alone Relay

Valve is identical to the ECU/Relay Valve except it does

not have the ECU and ECU mounting bracket. The relay

valves may be installed on the reservoirs or a frame

member.

The Stand Alone Relay Valve is the second relay valve in

systems with two relay valves and is labeled Relay Valve

“B” in the diagrams.

Pipe Fitting Torques

Refer to the following torque specifications when installing

pipe nipples. Torques are for NPT threads with thread

sealant applied. Do not use thread tape. Contamination

by thread tape can cause component failure.

Tighten pipe nipples as follows:

• With Thread Sealant - Finger tight plus 1 1/2 turns

• Without Thread Sealant - Finger tight plus 2 turns

Leak and Performance Test

1. Park vehicle on level surface and block wheels.

2. Make and hold brake application. No audible air leaks

are permitted.

3. Release parking brake and fully charge the air system

(governor cut out point).

4. Turn engine OFF. Apply the service brake several times,

then hold and check for prompt brake air chamber

application and release at all wheels.

5. Apply brake, then hold. Coat outside of relay valve with

a soap solution. No leakage is permitted.

NOTE: If a sluggish response is noted at all wheels, inspect

for kinked or obstructed air line leading to or from valve.

6. Increase system air pressure to governor cut-off. With

brakes released, coat exhaust port of relay valve with a

soap solution. Leakage of a 1” bubble in 5 seconds is

permissible.

7. Depress foot valve and keep depressed. Coat exhaust

port with a soap solution. Leakage of a 1” bubble in 3

seconds is permissible.
