Graco 234418 Manual De Usuario

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.

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” npt piping is recommended. Avoid 
using too many fittings, couplings, etc., which will 
restrict air flow.
