WARNING

Installation
8311826B
Installation
Grounding
The equipment must be grounded. Grounding reduces
the risk of static and electric shock by providing an
escape wire for the electrical current due to static build
up or in the event of a short circuit.
Pump: Use the ground screw (GS) and lockwasher on
the motor to attach a 244524 ground wire (Y). Tighten
the screw securely. Connect the other end of the ground
wire to a true earth ground.
Air and fluid hoses: use only electrically conductive
hoses.
Air compressor or hydraulic power supply: follow
manufacturer’s recommendations.
Spray gun: ground through connection to a properly
grounded fluid hose and pump.
Fluid supply container: follow local code.
Object being sprayed: follow local code.
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 sur-
face, such as paper or cardboard, which interrupts
grounding continuity.
To maintain grounding continuity when flushing or
relieving pressure: hold metal part of the spray gun
firmly to the side of a grounded metal pail, then trigger
the gun.
Flush Before Using Equipment
The equipment was tested with lightweight oil, which is
left in the fluid passages to protect parts. To avoid con-
taminating your fluid with oil, flush the equipment with a
compatible solvent before using the equipment. See
Flushing, page 14.
Mounting Accessories
See Dimensions, page 22 and Mounting Hole Lay-
outs, page 23.
FIG. 1 shows an air-powered system and FIG. 2 shows a
hydraulic-powered system.
Hoses
See FIG. 1 and FIG. 2. Be sure all hoses are properly
sized and pressure-rated for your system. Use only
electrically conductive hoses. Fluid hoses must have
spring guards on both ends. Use a whip hose (P) and a
swivel (R) between the main fluid hose (N) and the
gun/valve (S) to allow freer gun/valve movement.

Air Line Accessories
For air-powered pumps, install the following accessories
in the order shown in FIG. 1, using adapters as neces-
sary.
•Bleed-type master air valve (E): required in your
system to relieve air trapped between it and the air
motor when the valve is closed. Be sure the valve is
easily accessible from the pump and located down-
stream from the air regulator.
•Pump air regulator (F): to control pump speed and
outlet pressure. Locate it close to the pump.
•Air line filter (J): removes harmful dirt and moisture
from compressed air supply.
•Second bleed-type air valve (K): isolates air line
accessories for servicing. Locate upstream from all
other air line accessories.
Hydraulic Line Accessories
For hydraulic-powered pumps, install the following
accessories in the order shown in FIG. 2, using adapters
as necessary.
• Use a minimum 13 mm (1/2 in.) ID supply line (C),
and a minimum 22 mm (7/8 in.) ID return line (D).
The motor has a 3/4 npt(f) hydraulic oil supply fitting,
and a 1 in. npt(f) hydraulic oil return fitting.
•Supply line shutoff valve (U) isolates the pump for
service.
•Fluid pressure gauge (F) monitors hydraulic oil
pressure to the motor to avoid overpressurizing the
motor or lower.
•Pressure- and temperature-compensated flow
control valve (G) prevents the motor from running
too fast and possibly damaging itself.
•Pressure reducing valve (H) with a drain line (E)
runs directly to the hydraulic return line (D).
•Accumulator (J) reduces the hammering effect
caused by the motor reversing direction.
•Return line shutoff valve (V) isolates the pump for
service.
• Be sure your hydraulic power supply is equipped
with a suction filter to the hydraulic pump and a sys-
tem return line filter (W) of 10 micron size.
• Connect a 6 mm (1/4 in.) ID drain line (K) to the
barbed fitting on the drip pan, and place the free
end in a container to collect the drainage.
Fluid Line Accessories
Install the following accessories in the order shown in
FIG. 1 and FIG. 2, using adapters as necessary.
•Fluid drain valve (M): required in your system, to
relieve fluid pressure in the hose and gun.
•Fluid filter (L): with a 60 mesh (250 micron) stain-
less steel element to filter particles from the fluid as
it leaves the pump.
•Gun or valve (S): to dispense fluid.
•Fluid line swivel (R): for easier gun movement.
•Suction kit (T): enables the pump to draw fluid from
a container.
Accessory Air Control Kits are available for the NXT
Air Motor. The kits include a master air valve (E), air
regulator (F), and filter (J). Order the kit separately.
