Installing the Feed Pumps
1. Screw the bung adapter (40) and pump tightly into the
drum cover. See Fig 1.
2. Tighten the retainer (38) firmly to complete the airtight
seal.
3. Separate the two halves of the identification label (15)
along the perforation. Clean the surface of the air
motor with solvent and apply the appropriate label
(RES or ISO) to identify the type of material being
pumped.
4. Install an air regulator in the feed pump air inlet to
control pump speed. To install, remove the air valve
(8) and use suitable adapters for the regulator and
pin fitting. Use thread sealer on male threads.
WARNING
A bleed–type master air valve (E) is required in your
system, to help reduce the risk of serious injury,
including splashing fluid in the eyes or on the skin, and
injury from moving parts if you are adjusting or repairing
the pump.
The
bleed–type master air valve
(E) relieves air trapped
between this valve and the pump after the pump is shut
off. Trapped air can cause the pump to cycle
unexpectedly and result in serious injury, including
amputation. Locate the valve close to the pump.
