General Safety Information (Continued)
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.
