The equipment must be grounded to reduce the
risk of static sparking. Static sparking can cause
fumes to ignite or explode. Grounding provides an
escape wire for the electrical current.

Always ground the entire fluid system as
described below.

not conductive. Any system
used to pump flammable fluids must be properly
grounded.
• Follow your local fire codes.
Before operating the pump, ground the system as
explained below.

on a nonconductive surface, such as paper or
cardboard, which interrupts grounding continuity.
Check your system electrical continuity after the
initial installation, and then set up a regular schedule
for checking continuity to be sure proper grounding
is maintained.

1.
Install an air regulator and gauge (C) to control
the fluid pressure. The fluid stall pressure will be
the same as the setting of the air regulator.
2.
Locate a bleed-type master air valve (B) close to
the pump and use it to relieve trapped air. Be
sure the valve is easily accessible from the pump
and located downstream from the regulator.
Trapped air can cause the pump to cycle
unexpectedly, which could result in serious
injury from splashing.
3.
Locate another master air valve (D) upstream
from all air line accessories and use it to isolate
them during cleaning and repair.
4.
An air line filter (C) removes harmful dirt and
moisture from the compressed air supply.
5.
Install a grounded, flexible air hose (A) between
the accessories and the 1/8 npt(f) or 1/8 bspt
pump air inlet. Use a hose with a minimum 1/4 in.
ID. If a hose longer than 10 ft (3 m) is required,
use a larger diameter hose.
