System Accessories
The following instructions refer Typical Installation, F
IG
.
1, page 4.
Install the following accessories in the order shown in
Typical Installation (F
IG
. 1) using adapters as necessary.
To ensure maximum pump performance, be sure that
any accessory used is properly sized to meet your sys-
tem requirements.
• A bleed-type master air valve (C) and Fluid Drain
Valve (M) are required in your system to reduce the
risk of serious bodily injury from moving parts, injec-
tion or splashing in the eyes or on the skin when
shutting of the pump. The bleed-type master air
valve relieves air trapped between the air valve and
pump, after the pump is shut off. Trapped air can
cause the pump to cycle unexpectedly, which could
result in serious injury from splashing or moving
parts. Be sure the valve is easily accessible from the
pump and located downstream from the air regula-
tor.
• On the air line (A) install an air regulator (D) near
the pump air inlet (E) to control pump speed and
outlet pressure and an air line oiler (C) down-
stream from the regulator to provide automatic lubri-
cation to the air motor.
• Use an adequately sized air regulator to control
pump speed and fluid pressure.
• Upstream form the oiler, install an air filter (F) to
remove harmful dirt and moisture from the com-
pressed air supply.
Hose and Plumbing Lines
The following instructions refer to Typical Installation,
F
IG
. 1, page 4.
In this system, fluid and air lines may be either hoses or
hard plumbed. All lines must be grounded (see Ground-
ing, page 5).
• ALL FLUID HOSES MUST HAVE SPRING
GUARDS! The spring guards help protect the hose
from kinks or bends at or close to the coupling which
can result in hose rupture.
• Tighten all fluid connections securely before each
use. High pressure fluid can dislodge a loose cou-
pling or allow high pressure spray to be emitted from
the coupling.
• Never us a damaged hose or plumbing component.
Before each use, check the entire hose or plumbing
line for cuts, leaks, abrasion, bulging cover, damage
or movement of couplings. If any of these conditions
exist, replace the hose or defective components
immediately. DO NOT try to recouple high pressure
hoses or mend it with a tape or any other device. A
repaired hose cannot contain the high pressure
fluid.
Connecting Lines
1. Connect the air supply (A) to the 3/4 npsm(f) air
inlet (F).
2. Connect the fluid supply line (K) to the 1 inch
npt(f) fluid intake (J) and the fluid line (H) to the
3/4 npt(f) fluid outlet (G).
Flush Before Using Equipment
The equipment was tested with lightweight oil, which is
left in the fluid passages to protect parts. To avoid con-
taminating your fluid with oil, flush the equipment with a
compatible solvent before using the equipment.
