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.
