Fill the pump with oil

Fill the pump with oil as described below. Refer to
1. Remove the oil filler-plug (1).
2. Pour oil into the pump until the oil-level reaches the MAX mark on the bezel at the top of the oil sight-glass (12).
If the oil-level goes above the MAX mark, remove the oil drain-plug (11) and drain the excess oil from the pump.
3. After a few minutes, recheck the oil-level. If the oil-level is now below the MAX mark, pour more oil into the
pump.
4. Refit the oil filler-plug. Tighten the plug firmly by hand. Do not overtighten.

Electrical installation: single-phase motors

Ensure that the electrical installation of the pump conforms with local and national safety
requirements. It must be connected to a suitably fused and protected electrical supply and a
suitable earth (ground) point.
Ensure that the motor is correctly configured for the electrical supply voltage and frequency. If not, the motor
can be damaged.
3.6.1

Introduction

Note: The pump will restart automatically when the electrical supply is restored after an interruption and when
the pump cools after it has overheated. If automatic pump restart is not desired, use electrical control
equipment that must be reset manually.
Ensure that the electrical supply voltage corresponds with the voltage specified on the motor data plate.
Edwards recommends that connecting the electrical supply to the motor through a starter or circuit breaker that has
thermal over-current protection and can be adjusted to suit the full-load current ratings shown on the motor rating
plate. The fuse ratings must be calculated by a qualified electrician. The supplier of the thermal over-current
protection device may specify fuse ratings to ensure correct operation of the over-current protection device. Ensure
that the fuse used is suitable for the starting currents given on the motor rating plate.
The diameter of the outer sheath of the electrical supply cable must be within the range 7 to 10.5 mm. The cable
must conform in size and colour coding with local and national electrical installation regulations. The temperature
rating of the cable must be 70°C or greater.
