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 a ground screw (Z) and lockwasher on the motor to attach ground wire 244524 (Y). Tighten the screw securely. Connect the other end of the ground wire to a true earth ground. See F

IG. 1.

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 surface, 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.

Z Y

TI8250a

FIG. 1

Air and fluid hoses: use only electrically conductive

hoses with a maximum of 500 ft. (150 m) combined hose length to ensure grounding continuity. Check the electrical resistance of hoses. If total resistance to ground exceeds 29 megohms, replace hose immediately.

Air compressor: follow manufacturer’s recommendations.

Hydraulic power supply: follow manufacturer’s recommendations.

Surge tank: use a ground wire and clamp.

Spray gun: ground through a connection to a properly

grounded fluid hose and pump.

Fluid supply container: follow local code.

Installation

Accessories

Install the following accessories in the order shown in F

IG. 2 and FIG. 3, using adapters as necessary.

Air-Powered Pumps

For typical installation, see FIG. 2 on page 10.

Accessory Air Control Kits are available for the NXT Air Motor. The kits include a master air valve, air regulator, and filter. Order the kits separately. See manual 311239 for more information.

Air Line

• Bleed-type master air valve (M): required in your

system to relieve air trapped between it and the air motor when the valve is closed.

Trapped air can cause the pump to cycle unexpectedly, which could result in serious injury from splashing or moving parts.

Hydraulic-Powered Pumps

For typical installation, see FIG. 3 on page 11.

Hydraulic Power Supply

CAUTION

The hydraulic power supply must be kept clean at all to avoid damage to the motor and hydraulic power supply.

1. Blow out hydraulic lines with air and flush thoroughly before connection to the motor.

2. Plug hydraulic inlets, outlets, and line ends when disconnecting them for any reason.

Be sure the power supply can provide sufficient power to the motor. Be sure the power supply is equipped with a suction filter to the hydraulic pump.

Hydraulic Supply Line

• For Viscount I Plus motors, the hydraulic inlet

on the motor is 3/4 in., 37° flare. Use a minimum 1/2 in. (13 mm) ID hydraulic supply line (K).

Be sure the valve is easily accessible from the pump and located downstream from the air regulator. Be sure

the air bleed hole points away from the operator.

The air motor is rated to 100 psi (0.7 MPa, 7.0 bar). If you will apply more than 100 psi (0.7 MPa, 7.0 bar) to the system, install a safety relief valve between the bleed-type master air valve and the air motor.

• Pump air regulator (L): to control pump speed and

outlet pressure. Locate close to the pump.

• Air line filter (K): removes harmful dirt and mois-

ture from compressed air supply.

• Second bleed-type air valve (M): isolates air line

accessories for servicing. Locate upstream from all other air line accessories.

• For Viscount II motors, use a minimum 13 mm

(1/2 in.) ID supply line supply line (K). The motor has a 3/4 npt(f) hydraulic oil supply fitting.

• Supply line shutoff valve (S): isolates the motor

when servicing the system. See F

• Hydraulic fluid pressure gauge (P): monitors the

hydraulic oil pressure to the motor to avoid overpressurizing the motor or lower.

• Pressure- and temperature-compensated flow control valve (T): prevents the motor from running too fast, which can damage it.

• Pressure reducing valve (N), which has a drain line (M) running to the return line (K): controls the hydraulic pressure to the motor.

IG. 3.

8 311211L

Installation

Hydraulic Return Line

• For Viscount I Plus motors, the hydraulic outlet on the motor is 7/8 in., 37° flare. Use a minimum 5/8 in. (16 mm) ID hydraulic return line (J).

• For Viscount II motors, use a minimum 22 mm (7/8 in.) ID return line (J). The motor has a 1 in. npt(f) hydraulic oil return fitting.

• Return line shutoff valve (R): isolates the motor

when servicing the system.

CAUTION

To avoid damage to the pump, never use the return line shutoff valve to control the hydraulic flow. Do not install any flow control devices on the hydraulic return line.

• Return fluid filter (J): removes residue from the

hydraulic fluid to help keep the system running smoothly (10 micron size).

All Pumps

Fluid Line

• Fluid filter: with a 60 mesh (250 micron) stainless

steel element to filter particles from the fluid as it leaves the pump.

• Fluid drain valve (U): required in your system, to

relieve fluid pressure in the hose and gun.

• Fluid shutoff valve (D): shuts off fluid flow.

• Fluid pressure regulator: for more precise adjust-

ment of the fluid pressure.

• Gun or valve: to dispense fluid.

• Fluid line swivel: for easier gun movement.

• Suction kit: enables the pump to draw fluid from a

container.

• Inlet and outlet seals: prevent leakage in BSPP

models. Order 193423 for 1-1/2 in. inlet seal and 193422 for 1-1/4 in. outlet seal.
