Fill the pump with oil
Fill the pump with oil as described below. Refer to
for the item numbers in brackets.
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
CAUTION
Ensure that the motor is correctly configured for your electrical supply voltage and frequency. If you do not,
you can damage the motor.
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 you do not want the pump to restart automatically, use electrical
control equipment which must be reset manually.
Ensure that your electrical supply voltage corresponds with the voltage specified on the motor data plate.
We recommend that you connect the electrical supply to the motor through a starter or circuit breaker which has
thermal over-current protection which 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 your thermal over-current
protection device may specify fuse ratings to ensure correct operation of the over-current protection device. Ensure
that the fuse you use 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 your local and national electrical installation regulations. The
temperature rating of the cable must be 70 °C or greater.
WARNING
Ensure that the electrical installation of the pump conforms with your local and national safety
requirements. It must be connected to a suitably fused and protected electrical supply and a
suitable earth (ground) point.
