Surface-pump with 1 1⁄4” hosetails and 2x hose clips. The
surface-pump should have a maximum ow rate of more
than 1,500 litres per hour. The surface-pump should also
have a ow rate of no more than 3,000 litres per hour
when providing a pressure head of 25m. Please see your
distributor for a list of recommended surface pumps

provision for overow/tank switch if required
Good quality 1¼” and 1½” suction hoses
(equal lengths of at least the intended
distance from the well-head to the tank). The

Tools Needed For Installation
Heat source to soften the HDPE pipes in
step 13 (e.g. blow torch, hot air gun or
means to build a small re). You may wish
to use gloves to improve grip and avoid
burns whilst pushing heated pipes onto the
SLX-40 hosetails
2 pairs of adjustable pipe wrenches or water-
pump pliers for steps 5 and 25
Hole making tool for the tank ports in step 3
(e.g. hot pipe, hole saw or short, sti blade)
Hacksaw cutting blades for cutting hoses and
HDPE pipes
Pliers with wire
cutting blade
for cutting and
twisting wire
in step 14 and
cutting cable
ties in step 17
String and weight
to check the depth
of the well
13mm spanner for tightening M8 bolts if
used in step 26
Means to provide 100L of priming water
AFTER SLX-40 installation
100 litres
Optional or
recommended items:
• Fittings and pipes/hoses to plumb an
overow return to the well
• Woodscrews, anchor bolts or appropriate
fasteners to secure the well-head to
whatever platform structure is used to
support the SLX-40 at the top of the well
or borehole. (Please note that 3x40mm
M8 bolts are supplied for use with a metal
framework or concrete castings)

Install a suitable support to hold the Well-Head (D) centrally over the well so that it does not touch
or rub on the sides of the well. The support should be suciently sti and strong to support the
weight of up to 4 people plus 100kg.
If the well is greater than 20cm (8”) in diameter, please ensure that it is completely
covered and safe, ensuring it is not possible for a person to fall into the well!!

TIP:
Look into the tank to check that the surface-pump inlet does not suck in any air while
pumping. Check that any air remaining in the system has circulated and settled out in
the tank and the SLX-40 has a steady beat. This may take up to 5 minutes.
Please refer to the Troubleshooting section of the
‘User Guide’ booklet for further support if required.
