System Accessories
Install a bleed-type master air valve (D) close to the
pump air inlet (F), to relieve air trapped between it and
the air motor.
WARNING
The bleed-type master air valve (D) is required in
your system to shut off and relieve air pressure that
may be trapped in the air motor. This air could
cause the pump to cycle unexpectedly, which could
result in serious injury, including amputation or
splashing of fluid in the eyes or on the skin.
Install an air filter/regulator (C) in the pump air line,
upstream from the bleed valve , to control air inlet
pressure and to remove harmful dirt and contaminants
from your compressed air supply.
Install another bleed-type master air valve (D) up-
stream from all air line accessories and use it to isolate
the accessories during cleaning and repair.

On the air drop to the dispensing valve (J), install an
air regulator (L) to control air pressure to the valve.
Install a bleed valve (D) to use as a shutoff when
servicing the dispensing valve.
Connect air solenoid valves (E) to a timer control (K),
and set so the dispensing valve (J) will dispense at
proper intervals.
Connect the Hoses
Connect electrically conductive air supply hoses to the
air inlets of the pump and dispensing valve.
Connect the fluid line between the pump's 1–1/2"
flanged fluid outlet and the fluid inlet of the dispensing
valve.
NOTE: Be sure to install the complete system in
accordance with all state sanitary standard codes and
local regulations.
