Description
Haldex hydraulic power units are designed specifically to
operate on AC electric power. Each power unit is a custom
selected assembly consisting of a high performance
hydraulic pump, reservoir, motor, manifold interface block,
relief valve, pressure gauge and oil level sight gauge with
thermometer. They are controlled with NFPA D03 (D01)
directional control valves. Manifold and valve sold sepa-
rately. The power units can be coupled via suitable
hydraulic lines to a wide range of operating mechanisms.
They normally operate hydraulic cylinders, but can be used
with any other hydraulic actuating device.
Unpacking
Check unit for any shipping damage. The contents of the
carton will include (1) AC hydraulic power unit fully assem-
bled and tested. If there is any noticeable damage, please
contact the office where item was purchased.
Specifications

• Totally enclosed fan cooled motors
• Motors have continuous horsepower ratings (see chart)
• Adjustable relief valve preset at factory

4. Nameplate voltage must be available at the motor when
it is operating under load. Avoid voltage drop by using
adequate wiring.
5. Replace or repair damaged or worn power cord imme-
diately.
6. The use of 3-prong single phase adapters in Canada is
prohibited by the Canadian Electrical Code.
7. DOUBLE CHECK ROTATION! Motor rotation is clock-
wise facing fan end of motor.
8. On start-up, jog the motor to prime the pump to insure
adequate lubrication. After inlet line is full, motor may
be operated at full speed.
Never run the pump dry.
9. Keep all lines as short as practical.
10. Never exceed the maximum operating pressure.
11. Do not overtighten fittings, bolts, etc., as this can dam-
age the units.
12. Provide adequate cooling for the hydraulic oil so as not
to allow oil and/or component damage due to excessive
temperatures. Excessively high operating temperatures
can be hazardous and may cause property damage
and/or personal injury.
Installation
1. Select a good location to mount the hydraulic power
unit. It should be in a clean, dry area with adequate
ventilation and preferably near the electric power
source.
NOTE: Although the units have totally enclosed fan cooled
motors, they still need free air circulation to displace heat.
Avoid dusty conditions that could clog the reservoir
breather.
2. This hydraulic power unit is designed for vertical mount
with reservoir feet down and reservoir breather up.
Choose a flat mounting surface to bolt reservoir base to.
See unit dimensions for reservoir base bolt pattern.
The reservoir for this family of units is internally
plumbed for vertical mounting as noted above.
Mounting the unit in an inclined plane or any other
position will greatly reduce available usable oil in the
reservoir. This can cause oil foaming, erratic move-
ment of hydraulic components, and pump failure.
To minimize contamination problems, do not remove
plastic shipping plugs from hydraulic unit until you are
ready to install hoses and fittings.
3. HYDRAULIC INSTALLATION – Make sure that work
area and hydraulic components are clean and free from
dirt, lint, etc.
4. Fill the hydraulic unit reservoir with a good quality auto-
matic transmission fluid (ATF). Use a clean funnel fitted
with a fine mesh wire screen.
5. Remove (2) 9/16-18 SAE #6 shipping plugs from power
unit and install appropriate hoses or fittings.
Do not use teflon tape on NPTF Ports! This unit is
equipped with both SAE O-ring and NPTF type ports.
Do not overtighten fittings.
6. ELECTRICAL INSTALLATION – Motor nameplate volt-
age must be available at the motor when it is operating.
Choose a site that avoids long power cord runs.
Voltage drop increases with the length of power cord.
Larger wire diameter may be required.
7. When wiring the motor, follow all local electrical and safe-
ty codes as well as the National Electric Code (NEC) and
Occupational Safety and Health Act (OSHA).
8. For Three Phase Motors use 4-wire cords with grounding
type plugs.

SYMPTOM POSSIBLE CAUSE(S) CORRECTIVE ACTION
REPLACE OR REPAIR DAMAGED OR WORN POWER
CORDS IMMEDIATELY.
DO NOT OPERATE UNITS WITHOUT PROPER GROUNDING.
9. DOUBLE CHECK ROTATION! Motor rotation is clock-
wise facing fan end of motor.
Do not run hydraulic unit dry; Severe pump damage
may result.
Operation
Prior to operation:
1. Double check all hydraulic and electric connections.
2. Confirm that reservoir is filled with hydraulic fluid.
3. Put all equipment guards in place.
4. Clear all persons from work area.
5. Check for loose tools, equipment, or anything that might
interfere with operation of equipment.
OPERATION:
1. Start Up – When initially starting unit up, be sure to jog
the unit (intermittently run unit) several times. This will
prime the pump and fill the hydraulic lines.
Check motor fan rotation at this time to avoid damaging
pump or pump shaft seal.
IF MOTOR IS RUNNING WRONG ROTATION, SHUT OFF
ELECTRICAL POWER BEFORE ATTEMPTING TO
CHECK OUT MOTOR WIRING!
2. After hydraulic lines have been filled, check reservoir for
sufficient oil level. Replenish oil level if necessary.
Do not overfill.
Maintenance
1. Keep the reservoir filled with hydraulic fluid. Use a good
quality automatic transmission fluid (ATF). To fill the
reservoir with clean oil, use a clean funnel fitted with a
fine mesh wire screen. Do not use a cloth strainer.
Most pump/fluid motor failures, valve malfunctions, and
short unit life can be traced directly or indirectly to dirt or
other foreign materials (water, chips, lint, etc.) entering
or already in the hydraulic system.
2. Make frequent inspection of hydraulic fluid and change
if contaminated.
3. Regularly inspect hydraulic hoses and fittings for wear
or leakage.
4. Keep the unit clear of dirt and foreign materials.
5. Keep electrical connections clean.
