Installation
CAUTION
Provide a bracket for mounting the air accessories.
The fittings are not strong enough to support the
accessories and may cause one or more to break.
NOTE: Install the accessories in the order shown in
Figure 1.
D A pump runaway valve (H) shuts off the air to the
pump if the pump accelerates beyond the pre-ad-
justed setting. A pump which runs too fast can be
seriously damaged.
D An air line lubricator (G) provides automatic air
motor lubrication.
D A bleed-type master air valve (F) relieves air
trapped between it and the motor when the valve is
closed. Order Part No. 107142.
D The air regulator (E) controls pump speed and
pressure.
D An air line filter (D) removes harmful dirt and
contaminants from your compressed air supply.
D A drain valve (L) is required near the pump fluid
outlet to relieve fluid pressure in the pump, hose
and gun. Order Part No. 210657.
D Install an electrically conductive fluid hose (M) and
spray gun (N).
Grounding
Proper grounding is an essential part of maintaining a
safe system.
To reduce the risk of static sparking, ground the pump.
Check your local electrical code for detailed grounding
instructions for your area and type of equipment. Be
sure to ground all of this equipment:
D Pump: use a ground wire and clamp as shown
below.
D Truck bed or platform: according to your local code.
D Fluid hoses: use only electrically conductive hoses.
D Air compressor: follow manufacturer’s recommen-
dations.
D Spray gun: grounding is obtained through connec-
tion to a properly grounded fluid hose and pump.
D Object being sprayed: according to local code.
D Fluid supply container: according to local code.
D All solvent pails used when flushing or relieving
pressure, always hold a metal part of the gun firmly
to the side of a grounded metal pail, then trigger the
gun.
To ground the pump:
To ground the pump, use a ground wire and clamp as
shown below. Remove the ground screw (Z) and insert
through the eye of ring terminal at end of ground wire
(Y). Fasten the ground screw back onto the pump and
tighten securely. Connect the other end of the ground
wire to a true earth ground. See Fig. 2. To order a
ground wire and clamp, order Part No. 222011.
