Pump Installation - Graco A Series Instructions-Parts List Manual

11. Raise the pump out of the pail. Trigger the fun to
force the water from the system. DO NOT run the
pump dry for more than 10 seconds to avoid damag-
ing the pump packings.

Pump Installation

NOTE: Be sure the system has been thoroughly
flushed.
1. Loosen the hose clamp on the suction hose. Slide
the suction hose as far as possible onto the pump
intake valve.
2. Slide the clamp up and tighten its screw snugly.
A loose clamp prevent the pump from getting ade-
quate fluid supply, which results in low fluid flow
and/or spitting air from the gun.
3. Remove the bung cover from the drum and open the
vent hole.
4. Loosen the thumbscrew on the bung adapter.
