Before connecting the system piping to the pump, the unit is to be securely fastened to the
bulkhead. Long or heavy piping sections shall not be supported from the pump but by separate
supports.
ALIGNMENT: No inspection or corrections to pump/motor alignment are necessary.
Install the oil reservoir and top up the reservoir with the supplied oil.
WARNING:
THE OIL RESERVOIR SHALL ALWAYS BE SUFFICIENTLY FILLED WITH OIL, AS
THE PROPER FUNCTIONING OF THE GAS SEAL LOCATED IN THE CENTRE OF
THE PUMP MAIN PLATE RELIES ON THE PRESENCE OF OIL, FOR LUBRICATING,
SEALING AND COOLING PURPOSES.
6.3.3 Electrical installation pump
Verify the power supply. This is to match the data as shown on the electric motor nameplate.
Grounding is to be carried out utilizing the grounding bolt located inside the terminal box, before the
motor is connected to the mains.
6.3.4 First start
CAUTION:
UNDER NO CIRCUMSTANCES SHOULD THE PUMP RUN WITHOUT LIQUID.
THE PUMP HOUSING MUST FIRST BE FILLED WITH LIQUID, OTHERWISE THE
PUMP WILL SEIZE AND DAMAGE WILL OCCUR.
6.3.4.1 Self priming
The pump will not function or prime until the casing is filled with liquid. Make sure any discharge
valve is opened before starting, enabling air to be released. Running the pump with zero capacity
will cause excessive system pressure; heat generated in the pump and may overload the electric
motor. Make sure any system valve should be fully opened when the pump is being started or
stopped.
6.3.4.2 Direction of rotation
This can be seen or checked from the motor side only. Make sure that all piping is installed, and the
pump is filled with water. Switch-on the pump unit for a short moment only! Look at the motor fan
and notice the direction in which the fan spins. This must be clockwise, when looking from the back
cover of the motor. An arrow also indicates correct direction of rotation. If direction of rotation is
wrong, interchange any of two line wires of the power cable in the terminal box.
