Installation
Air Line
WARNING
An air line quick coupler (B) is required in your
system to relieve air trapped between this valve
and the pump. See Fig. 2. Trapped air can cause
the pump to cycle unexpectedly, which could result
in serious injury, including splashing in the eyes or
on the skin, injury from moving parts, or contamina-
tion from hazardous fluids.
CAUTION
Before connecting the permanent air line to the
regulator (A), blow out all lines with air to remove
contaminants that can clog or damage the regulator,
hose, or pump air valve.
CAUTION
The pump exhaust air may contain contaminants.
Ventilate to a remote area if the contaminants could
affect your fluid supply. See Air Exhaust Ventilation
on page 9.
1. Install the air line accessories as shown in Fig. 2.
Mount these accessories on the wall or on a
bracket. Be sure the air line supplying the
accessories is electrically conductive and bonded.
2. Use the air regulator (A) to control the pump fluid
outlet pressure. The fluid pressure will be the
same as the setting on the regulator gauge.
3. Install an electrically conductive, flexible air hose
(J) between the regulator (A) and the 1/4 npt(f)
pump air inlet. Use a minimum 1/4” (6.3 mm) ID air
hose. Screw an air line quick disconnect coupler
(B) onto the end of the air hose (J), and screw the
mating fitting into the pump air inlet snugly. Do not
connect the coupler (B) to the fitting yet.
Fluid Supply Line
Use electrically conductive fluid hoses (J or F). Be
sure the lines are bonded all the way from the fluid
supply to the grounded pump.
The pump fluid inlet is 3/4 npt(f). See Fig. 4. Screw
the fluid fitting into the pump inlet snugly. Do not
overtighten.
For the Gear Oil Evacuation System, install a
control valve (D) and an appropriate wand (E). See
Fig. 2.
For the Waste Oil Receiver Evacuation System,
connect an appropriate suction hose (F) and fluid
quick coupler (G) between the pump fluid inlet and
the waste oil receiver (M). See Fig. 3.
If the inlet pressure to the pump is more than 25%
of the outlet working pressure, the ball check valves
will not close fast enough, resulting in inefficient
pump operation.
At inlet fluid pressures greater than 15 psi
(100 kPa, 1.0 bar), diaphragm life will be shortened.
See the Technical Data on page 30 for maximum
suction lift and flow rate loss at various lift
distances.
Fluid Outlet Line
WARNING
A fluid drain valve (C) is required in your system to
relieve pressure in the hose if it is plugged. See
Figs. 2 and 3. The drain valve reduces the risk of
serious injury, including splashing in the eyes or on
the skin, or contamination from hazardous fluids
when relieving pressure. Install the valve close to
the pump fluid outlet.
Use electrically conductive fluid hoses (L). Be sure
the lines are bonded all the way from the grounded
pump to the waste storage tank.
The pump fluid outlet is 3/4 npt(f). See Fig. 4.
Screw the fluid fitting into the pump outlet snugly.
Do not overtighten.
Install a fluid drain valve (C) near the fluid outlet.
See the WARNING above.
