Air and Fluid Line Accessories
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 Use thread sealant on male threads except at
swivel connections.
D Install a bleed-type master air valve upstream from
the pump air regulator, but within easy reach of the
pump.
To order a 300 psi (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 the pump end of the air supply lines about
24 in. (610 mm) above the floor.
D If you are installing several pumps, put tees in the
supply line immediately above and behind the pump
locations. See Fig. 5.
