Bleed-type Master Air Valve (B)
Trapped air can cause the pump to cycle unexpectedly,
which could result in serious injury from splashing or
moving parts.
•
Required in your system to relieve air trapped
between it and the air motor when the valve is
closed.
•
Be sure the valve is easily accessible from the pump
and located downstream from the air regulator.

Grounding
TI8802a
The equipment must be grounded. Grounding reduces
the risk of static and electric shock by providing an
escape wire for the electrical current due to static build
up or in the event of a short circuit.
See F
(61) to attach Part No. 244524 Ground Wire (GW) at the
rear of the air motor. Tighten the screw securely. Con-
nect the other end of the ground wire to a true earth
ground.
