Installation

1.Before installing air line components, blow out the pipe line to remove debris. Be sure air to the regula- tor is clean. Erratic operation or loss of regulation is usually caused by dirt in the regulator.

2.Install the Air Drying System as close as possible to the equipment it serves. Use template 289185, pro- vided, to position system.

3.Install air shut-off valve 288798 upstream from the air system to isolate it for service.

4.Install system so air flows through filters in the direc- tion noted on top of filter.

5.A minimum 1/2 in. npt piping is recommended. Avoid using too many fittings, couplings, etc., which will restrict air flow.
