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 unit as close as possible to the equipment
it serves.
3.
Install a main air shut-off valve upstream from the
air controls to isolate them for service.
4.
Install system so air flows through filters in the direc-
tion noted on top of filter.
5.
A minimum 1/2” npt piping is recommended. Avoid
using too many fittings, couplings, etc., which will
restrict air flow.
