These pressures are factory set but can be adjusted using the plastic screw on
the pressure switch. The pump may continue to operate for a short while after
the supply valve is turned off until the cut-out pressure is reached.
In order for the system to operate
correctly it is necessary to pressurise
the air chamber to 3.5 Bar (50psi),
which is carried out as follows:.
Unscrew the protective cap on the
end of the air chamber to reveal the
air valve and use an air line or foot
pump to charge the pressure vessel
to the specified pressure.
Check the air pressure gauge until
satisfied and replace the protective cap when completed. This procedure
MUST be carried out before connecting to the water supply.
PRIMING THE PUMP
When suction lift is used to draw water into the pump it is essential that all
connections and hoses are completely air tight or the system will not work.
Although the pump is a 'self priming'
type, it is still 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/repair. This
is carried out as follows:-
1. Remove the small filler plug on the
top of the pump chamber and 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 and fill the filter bowl with water.
2. Adjust any valves 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 quickly start to flow
through the system. If, depending upon the suction depth, water does not
flow, check to ensure:
• The inlet pipe is secure and free from defects. Even a pin hole could
prevent the pump from drawing water efficiently. This is the most
common problem encountered when operating water pumps.
