Gas and fluid hoses: Use only grounded
hoses with a maximum of 500 ft (150 m) com-
bined hose length to ensure grounding
continuity.
Solvent pails used when flushing: Follow
local code. Use only conductive metal pails,
placed on a grounded surface. Do not place
the pail on a nonconductive surface, such as
paper or cardboard, which interrupts ground-
ing continuity.
Fluid supply container: follow local code.
Suction device nozzle: must be bonded to
metal container from which it is suctioning by
firm metal-to-metal contact to a properly
grounded suction hose and pump.
Piping, valves, and fittings: use only electri-
cally conductive materials. Bond and ground
per code.
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 a regulator (C) and gauge to control
the fluid pressure. Locate it close to the
pump.
R
2. Locate a bleed-type master gas valve (B,
required in your system) close to the pump
and use it to relieve trapped natural gas. Be
sure the valve is easily accessible from the
ti12214a
pump and located downstream from the
regulator.
Trapped gas can cause the pump to cycle
unexpectedly, which could result in serious
injury from splashing.
3. Locate another bleed-type master valve (E)
upstream from all natural gas line accesso-
ries and use it to isolate them during clean-
ing and repair.
4. A filter (F) removes harmful dirt and mois-
ture from the compressed gas supply.
5. Install a grounded, flexible gas hose
between the accessories and the 1/2 in.
npt(f) pump inlet (D). See F
minimum 1/2 in. (13 mm) ID hose.
