Installation
Grounding
Pump: use a ground wire and clamp. See F IG . 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 immedi-
ately.
Hydraulic power supply: follow manufacturer’s recom-
mendations.
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 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.
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.

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
IG . 2, page 9) and Part No. 218742 Stand
for 3000 and 4000cc Pumps (see F
IG . 3, page 10).
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.
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.
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.
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 con-
taminating your fluid with oil, flush the equipment with a
compatible solvent before using the equipment. See
Flushing, page 12.

Installation
83A0537G
Accessories
Install the following accessories in the order shown in
F
IG . 2, using adapters as necessary.
Hydraulic Power Supply
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.
•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 over-
pressurizing 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).
• 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.
•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 F IG . 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.
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 thor-
oughly before connection to the motor.
2. Plug hydraulic inlets, outlets, and line ends when
disconnecting them for any reason.
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.
