Installation
Air and Fluid Line Accessories
NOTE: Install the accessories in the order shown in
Fig. 2 on page 5.
CAUTION
Do not hang the air accessories directly on the air
inlet. Mount them on brackets. The fittings are
not strong enough to support the accessories and
may break.
D Install a bleed-type master air valve (K) upstream
from the pump air regulator (C), but within easy
reach of the pump.
To order a 300 psi (2.1 MPa, 21 bar) maximum
working pressure, 1/2 in. npt bleed-type master air
valve, order Part No. 107142.
WARNING
A bleed-type master air valve is required in the
system to help reduce the risk of serious bodily
injury, including fluid injection, splashing in the
eyes, and injury from moving parts when
adjusting or repairing the pump. This valve
relieves air trapped between the valve and the
pump to prevent the pump from cycling unex-
pectedly.
D 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.
To order a pump runaway valve, order Part No.
224040.
D Install an air line lubricator (F) for automatic air
motor lubrication.
To order a 250 psi (1.74 MPa, 17.4 bar) maximum
working pressure air line lubricator, order a Part No.
below:
3/8 in. npt 214847
1/2 in. npt 214848
D Install an air regulator (C) to control pump speed
and pressure.
To order a 300 psi (2.1 MPa, 21 bar) maximum
working pressure regulator, order a Part No. below:
3/8 in. npt 109075
1/2 in. npt 244844
D Install an air line filter (E) to remove harmful dirt
and contaminants from your compressed air supply.
To order a 250 psi (1.74 MPa, 17.4 bar) maximum
working pressure air filter, order a Part No. below:
3/8 in. npt 106148
1/2 in. npt 214849
