i.e. Although the pump is capable of delivering water to a maximum head of

48 metres, the hydrotronic unit will not switch the pump ON if the vertical

height above outlet of the unit is greater than 14 metres.

PRIMING

When suction lift is used to draw water into the pump it is essential that all

connections and hoses are completely air tight, otherwise the system will not

work.

Although the pump is a 'self priming' type, it is nevertheless necessary to

completely fill the inlet side of the pump with water before being started for

the first time, or if the system has been drained for maintenance or repair

purposes. This is known as priming the pump and is carried out as follows:-

1. 1.Locate and remove the small filler plug, situated on the top of the pump

chamber, and slowly fill the pump with water until all air is expelled.

NOTE: If a filter is fitted to your pump it is recommended that you remove

the brass plug on top of the unit and fill the bowl with water.

2. Adjust any device which may be fitted to the outlet side of the pump, so as

to ensure as great a flow as possible.

3. Switch on the pump and check for leaks. Water should start to flow through

the system after a short while. If, after 2-3 minutes, depending upon the

suction depth, water does not flow, check to ensure:

• The inlet pipe is completely secure and completely free from

defects. Even a pin hole could prevent the pump from drawing

water. This is the most common problem encountered when

operating water pumps.

• The pump body has been primed correctly and is completely filled

with water.

NOTE: If the pump is gravity or pressure fed, priming will not be

necessary, as the pressure of water will purge the system of air.

It is essential that all connections and hoses are completely air tight, otherwise

the system will not work.
