TESTING THE AD-IPAIR DRYER

Before placing the vehicle in service, perform the following tests.

1.Close all reservoir drain cocks.

2.Build up system pressure to governor cutout and note that the AD-IPair dryer purges with an audible escape of air.

3.“Fan” the service brakes to reduce system air pressure to governor cut-in. Note that the system once again builds to full pressure and is followed by a purge at the AD-IPair dryer exhaust.

4.It is recommended that the following items be tested for leakage to assure that the AD-IPair dryer will not cycle excessively.

(A)Total air system leakage (See Bendix publication BW5057 “Air Brake Handbook.”)

(B)Compressor unloader mechanism.

(C)Governor.

(D)Drain cock and safety valve in first (supply) reservoir.

(E)All air connections leading to and from the first (supply) reservoir.

(F)Delivery check valve.
