4.3 Electrical Connections
THE PUMP IS FACTORY EQUIPPED WITH THE COMMON
ELECTRICAL PLUG FOR A GIVEN VOLTAGE, ALTERING THE
PLUG TYPE SHOULD ONLY BE DONE BY A QUALIFIED
ELECTRICIAN, ADHERING TO ALL APPLICABLE LOCAL
AND NATIONAL CODES.
1.
The disconnect and line circuit protection to be provided by customer.
Line circuit protection to be 115% of motor full load current at
maximum pressure of application
2.
For additional information, refer to pump name plate for power rating.
Also refer to Table 4 at the back of this document for motor current
draw information.
4.4 Oil Level
Check the pump oil level prior to start-up. If oil level is low,
remove the SAE #10 plug from the fill pipe extension and add oil
as needed (see Figure 1).
The reservoir is full when the oil level is as shown in Figure 4.

IMPORTANT: Add oil only when all system components are fully
retracted, or the system will contain more oil than the reservoir
can hold.

Thread hose(s) into outlet port(s) of the valve (see valve body for
port identification).
Clamp (extend) hose to valve port "A".
Unclamp (retract) hose to valve port "B".
Gauge to valve port "GA", "GB" or "GP".
("GA" measures "A" port pressure, "GB" measures "B" port
pressure, "GP" measures pump pressure down stream of system
check. On models equipped with the optional pressure
transducer, the transducer is factory-installed in the "GP" port.)
5.0 OPERATION
Warning: Review sections 5.1-5.5 and 6.0-6.5 before
starting pump. On pumps equipped with the optional
pressure transducer, be sure that Dwell Mode operation
and functions are clearly understood.
1.
Check the oil level of pump and add oil if necessary.
2.
Make sure the shipping plug has been removed and the
breather cap is installed. (See Section 4.1)
3.
Connect unit to power. Wait until "OK" is displayed before
pressing any button on shroud or pendant. NOTE: During the
boot sequence, the microprocessor identifies any button
operation as a potential malfunction and prevents the motor
from starting. Reset by disconnecting power for 10 seconds.
4.
For an overview of pump operation, including pendant
functions, refer to sections 5.1-5.5. For detailed LCD Panel
operation instructions, see sections 6.0-6.5.
5.1 Pump Shroud Controls & LCD Panel (See Figure 6)
The LCD panel is mounted on the pump motor shroud. Refer to
sections 6.0 through 6.5 for detailed LCD panel operating
instructions, menu descriptions and additional information.

Apply 1-1⁄2 wraps of Teflon tape
or other suitable sealant to the
hydraulic hose fitting, leaving the
