c) Electrical connection:
IMPORTANT:
If the supply lead is damaged, it must be replaced by the manufacturer, its after-sales
service or a similarly qualified technician in order to prevent any danger (contact the
dealer for the list of approved after-sales service agents).
1. Check that the mains power supply is the same as that stated on the pump
indicator plate.
2. Check that the supply lead is not damaged.
3. Turn off power of the wall socket which the pump will be connected to using the
separation device (see section entitled "Major recommendations").
4. Connect the cable plug to the 10/16A wall socket. The latter must have an
earthing pin.
5. Turn power back on for several seconds in order to carry out a no-load test of the
pump. Do not operate the pump for more than 2-3 seconds in order to avoid
excessive over-heating. Such an occurrence would cause permanent damage.
6. When power supply is again turned off, proceed to connect up pipes as set out in
the following paragraphs.
4) CONNECTION OF THE SUCTION PIPE
The set of pipe's fittings must be mounted using Teflon so as to ensure complete
air-tightness.
In the case of fittings with gaskets or O-rings, it is not necessary to use Teflon.
Ensure that the gaskets hold firm over time .The suction pipe must have a minimum
diameter of 25 mm and be rigid to prevent crushing. We recommend fitting a strainer
(mounting with Teflon). Use clamping rings if necessary.
In all cases, the suction pipe must not be oriented upwards. In the case of a chamber
with sand or gravel, position the strainer 50 cm from the bottom or in a bucket at the
bottom of the chamber.
IMPORTANT!
It is imperative that the suction pipe which include a non-return valve.
It is therefore necessary to ensure that this valve is included or obtain one prior to any
connection. We recommend the use of a set-up comprising a strainer plus non-return
valve.
