Graco Inc. 309967C Manuale Utente

The installation shown below is only a guide for selecting and installing system components and accessories. Con-
tact your Graco distributor for assistance in designing a system to suit your particular needs.

•

Install a pump runaway valve (G) to shut off the air 
to the pump if the pump accelerates beyond the pre-
adjusted setting. A pump that runs too fast can be 
seriously damaged.

•

Install an air line lubricator (F) for automatic air 
motor lubrication.

•

Install a bleed-type master air valve (H) to relieve air 
trapped between the valve and the motor when the 
valve is closed.

•

Install the air regulator (C) to control pump speed 
and pressure.

•

On the main air supply line from the compressor, 
install an air line filter (E) to remove harmful dirt and 
contaminants fro the compressed air supply.

•

For models 253384 through 253390, install the pro-
vided air regulator/safety valve (K) at the pump air 
inlet with the nipple (9a, also included).

NOTE: Install air line accessories in the order 
shown in the Typical Installation illustration.

Trapped air can cause the air motor to cycle 
unexpectedly, causing serious injury if you are 
adjusting or repairing the pump. Be sure to follow the 
Pressure Relief Procedure on page 11.

Avoid hanging air accessories directly on the pump 
air inlet. The fittings are not strong enough to sup-
port the accessories and may cause one or more to 
break. If accessories must be installed directly on 
the pump, provide a bracket on which to mount 
them.
