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 wire and clamp. See FIG. 1. Loosen the locknut (W) of the grounding lug (Z). Insert one end of the wire (Y) in the ground lug and tighten the locknut securely. Connect the ground clamp to a true earth ground. Order Part No. 237569, Ground Wire and Clamp.

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 25 megohms, replace hose immediately.

Hydraulic power supply: follow manufacturer’s recommendations.

Surge tank: use a ground wire and clamp.

Dispense valve: ground through a 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 surface, such as paper or cardboard, which interrupts grounding continuity.

IG. 1 Ground Wire

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.

Installation

Stand Mount

Mount the pump in the accessory pump stand (B). Use Part No. 253692 Stand for 750, 1000, 1500, and 2000cc Pumps (see F for 3000 and 4000cc Pumps (see F

See Mounting Stand Hole Layouts on page 22. Secure the stand to the floor with M19 (5/8 in.) bolts which engage at least 152 mm (6 in.) into the concrete floor to prevent the pump from tipping.

IG. 2, page 9) and Part No. 218742 Stand

IG. 3, page 10).

Wall Mount

1. Ensure the wall is strong enough to support the weight of the pump assembly and accessories, fluid, hoses, and stress caused during pump operation.

2. Ensure that the mounting location has sufficient clearance for easy operator access.

3. Position the wall bracket at a convenient height, ensuring that there is sufficient clearance for the fluid suction line and for servicing the lower.

Plumbing

Install a fluid shutoff valve (D) between the mix tank (A) and the pump.

When using a stainless steel pump, use stainless steel plumbing to maintain a corrosion-resistant system.

Flush Before Using Equipment

The equipment was tested with lightweight oil, which is left in the fluid passages to protect parts. To avoid contaminating your fluid with oil, flush the equipment with a compatible solvent before using the equipment. See Flushing, page 12.

4. Drill four 7/16 in. (11 mm) holes using the bracket as a template. Use any of the three mounting hole groupings in the bracket. See 255143 Wall Mount Bracket, page 23.

5. Bolt the bracket securely to the wall using bolts and washers designed to hold in the wall’s construction.

6. Attach the pump assembly to the mounting bracket.

7. Connect air and fluid hoses.

IG. 2, using adapters as necessary.

Hydraulic Power Supply

NOTICE

The hydraulic power supply must be kept clean at all times 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 (L).

• For Viscount II motors, use a minimum 13 mm (1/2 in.) ID supply line (L). The motor has a 3/4 npt(f) hydraulic oil supply fitting.

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

• Return line shutoff valve (R): isolates the motor when servicing the system.

NOTICE

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).

Fluid Line

For typical installation, see FIG. 2 on page 9.

• 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.

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

when servicing the system.

• 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.

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 (K).
