Installation
Air Control Accessories
Install the accessories in the order shown in Fig. 4.
Mount only the air regulator (E) and a master air valve
(A) at the pump. Mount all other accessories on sepa-
rate wall brackets to reduce stress on the pump inlet.
Note that one air filter (B) can serve multiple pumps by
using an air manifold downstream from the air filter.
WARNING
INJECTION HAZARD
Bleed-type master air valves (A) are required in the
system in the positions shown in the Typical Instal-
lation drawings. These valves are used during
system pressure relief to relieve air trapped in the
air line. Trapped air can cause the pump to cycle
unexpectedly and result in serious injury from
moving parts, fluid injection, or fluid splashing.

1. Install a bleed-type master air valve (A) in the
pump air inlet.
2. Install an air regulator and gauge (E) to control
pump outlet pressure.
3. Install a pump runaway valve (D) for each feed
pump to automatically shut off the air to the pump
if the pump accelerates beyond the pre-adjusted
setting. A pump which runs too fast can be seri-
ously damaged.
4. Install an air line lubricator (C) for automatic air
motor lubrication.
5. Install an air filter (B) to remove harmful dirt and
moisture from the compressed air supply.
Automatic Pressure Relief Valves
WARNING
COMPONENT RUPTURE HAZARD
To reduce the risk of component rupture,
which could cause serious injury and
property damage, the appropriate auto-
matic pressure relief valve (18) is required for
each fluid on a plural component pump.
These valves automatically relieve fluid pressure if
the pump output pressure exceeds the valve’s
preset pressure. Over-pressurization may occur if
there is a fluid line clog upstream from the valve or
if any other condition exists that causes one of the
pumps to cavitate and direct all fluid pressure to
the other pump(s).
See the Model Chart on page 6 to determine the
preset pressure in your system.
