1. Attach the foot valve to the end of the suction
hose to prevent stones etc, from being drawn
up, which could cause damage to the pump.
Keep the foot valve clean. If it is likely to clog
with dirt or debris, proceed by either:
a. Preparing a bed of stones on which to rest the
foot valve.
b. Position the valve so that it stays clear of the
bottom of the pit, pond or excavation.
c. Tie the foot valve inside a basket or bucket.
PREPARING THE BOOSTER PRESSURE TANK
These pumps utilise an air pressure tank and regulator to provide a constant
water pressure at the outlet. The pump will automatically cut in when the
water pressure reaches a pre-set value. The regulator pressure is factory set
and must not be altered.
For the system to operate correctly,
it is necessary to pressurise the
pressure tank to between its rated
operating pressure of 1.5 bar (22 psi)
and 3.0 bar (44 psi) as follows;
1. Unscrew the large protective
cap on the end of the pressure
tank to reveal the air valve as
shown in Fig 3.
2. Use an airline or foot pump to
pressurise the tank.
3. Check the pressure with a
standard pressure gauge and
replace the protective cap when completed.
Important; 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 tight or the system will not work.
Although the pump is of the ‘self-priming’ type, it is still necessary to
completely fill the inlet side of the pump with water prior to initial starting, or if
the system has been drained for any other reason. Priming is carried out as
follows.
