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 (see Figure 1).
2. For more information, refer to pump name plate for power
rating.
4.4 Fluid Level
Check the oil level of the pump prior to start-up, if necessary add
oil by removing the SAE #10 plug from the cover plate (see Fig.
2). The reservoir is full when the oil level reaches the top of the
sight glass. (Fig. 4).
Tank is full
when oil level
is here.
4 and 8 liter
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).
Extend hose to valve port "A"
Retract hose to valve port "B" (if applicable).
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).
5.0 OPERATION
Warning: Pumps with optional pressure transducer,
review sections 5.7, 6.4 A-B, & 6.5 A-C on "SET PRES"
and "AUTOMODE" before starting pump.
Warning: Pumps with optional pressure switch, review
sections 5.8 before starting pump.
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. Place manual control valve (if equipped) in the Neutral
position.
4. Connect unit to power. Wait 2 seconds (LCD units, wait until
"OK" is displayed) before pressing any button on shroud or
pendant. NOTE:
microprocessor identifies any button operation as a potential
malfunction and prevents the motor from starting. Reset by
disconnecting power for 10 seconds.
5. For motor On/Off and valve operation, see sections 5.1 – 5.6
for your specific configuration instructions.
