Electrical power
The motor size determines the full load amperes, the overload settings, and the wire sizes. Refer to the technical drawings
for more information.

The electrical power requirements are on the data plate on the rear of the pump and on the inside of the electrical
enclosure door.
Make sure that the primary feed protection device (circuit breaker or fuse) is sized to handle inrush and steady-state
current.
Use a motor-start circuit breaker or the equivalent if time-delayed high-inrush fuses are not permitted by local or national
codes.
Air
The recommended air pressure is 5 bar or 483 kPa (70 psi).
DANGER
To reduce the risk of serious injuries or death, wear approved protection and follow safety recommendations
when working with electricity.
WARNING
Make sure that a line disconnect switch for incoming electrical power is installed near the pump’s power
supply to serve as a supply-voltage disconnecting or isolating device.
CAUTION
Air pressure higher than 6 bar or 552 kPa (80 psi) can cause damage to the bleed-down valve.
Air should be dried and filtered before it enters the pump.
