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.
