Stand and Mounting
For pumps that are provided with a stand, the pump
must be mounted to the stand before securing the pump
to the mounting surface. Ensure that the pump is
securely mounted to the stand.

1. Ensure that the mounting surface is level and can
support the weight of the pump, lines, and
accessories, as well as the stress caused during
operation.
2. Mount the pump and stand assembly on a level
surface and secure the assembly to the mounting
surface. See
Pump Dimensions
dimensions of the mounting holes for your pump.
NOTE:
For ease of operation and service, mount
the pump so the air valve cover, air inlet, and fluid
inlet and outlet ports are easily accessible.
Air Line
1. Install the air line accessories as shown in F
Verify that the air line supplying the accessories is
properly grounded.
a. Install an air regulator (B) and air pressure
gauge (T) to control the air pressure. Reducing
the supplied air pressure will reduce the pump’s
fluid outlet pressure.
b. Locate one bleed-type master air valve (C)
close to the pump and use it to relieve trapped
air. Locate the other master air valve (A)
upstream from all air line accessories and use it
to isolate them during cleaning and repair.
c. The air line filter (R) removes harmful dirt and
moisture from the compressed air supply.
2. Install a conductive, flexible air line (D) between the
accessories and the 1/2 npt(f) pump air inlet (F).
Use a minimum 9.5 mm (3/8 in.) ID air line. If
necessary, install an air line coupler (E) between the
air line (D) and the pump air inlet (F), and tighten
until snug.
The pump may be very heavy (see
Technical Data
for specific weights). If the pump must be moved,
and have two people lift the pump by grasping the
outlet manifold securely, or use appropriate lifting
equipment. Never have one person move or lift the
pump.
A bleed-type master air valve (C) is required in the
system to relieve air trapped between this valve and
the pump. Trapped air can cause the pump to cycle
unexpectedly, which could result in serious injury,
including splashing in the eyes or on the skin. See
