- When operating indoors you must ensure that there is a drain in the floor or a leak prevention mechanism.
- Before starting up, check the suction hose to ensure that it is sealed. Bubbles of air in the suction hose are
an indication that there may be leaks and may lead to failure of the device.
4.3- Electrical connection
a) Make sure that the power supply corresponds with the connection specifications of the device (see rating
label).
b) Check that the power cable is not damaged.
c) Connect plug to a wall socket 10/16A fitted with a ground connection.
d) Switch on the pump for 2 to 3 seconds to perform a dry run test of the pump.
Do not operate the pump without water for more than 2 to 3 seconds to avoid overheating. This will cause
permanent damage.
e) Disconnect the pump from the power supply (remove the plug from the wall socket), and then proceed
with suction and delivery line connection, as described in the following paragraphs.
f) Ensure that the electrical connection is protected against water splashing.
g) When operating outdoors, the electrical connections must be splash-proof; they must not lie in water.
h) Extension cords must have sufficient wire cross section; cable drums must be complete unwound.
4.4- Connecting the suction line (not supplied)
The suction hose (not supplied) must have a minimum diameter of 25 mm or 32 mm according to model
[refer to specs table] and must be rigid and kink resistant to prevent crushing and suitable for vacuum.
The assembly connections must be sealed with hemp and Teflon or thread sealing tape so that the sealing is
perfect.
For fittings equipped with gaskets or O-rings, it is not necessary to add Teflon or sealing tape.
Check the correct sealing over time.
Do not forget to check the connections of the strainer (mounted with Teflon). Add clamps if necessary.
In any case, the suction hose must not be directed upwards.
In the case of wells with sand or gravel, put the strainer 50cm from the bottom or in a bucket into the well.
The suction line should be as short as possible, since the suction capacity decreases as the length of the line
increases.
The suction line should ascend steadily towards the pump to prevent air pockets.
Sufficient water supply must be assured; the end of the suction line must always be in water.
The suction line must be installed so that it does not exert any mechanical force or tension on the pump.
If the conveying medium is contaminated, a suction filter must be used to protect the pump from sand and
dirt.
IMPORTANT! It is recommended to install a check valve.
Before starting, carefully check the suction hose to make sure that it is properly sealed. Air bubbles in the
suction line are an indication that there may be a leakage!
4.5- Connecting the discharge line (not supplied)
The discharge hose (not supplied) must have a minimum diameter of 25 mm and must be rigid and kink
resistant to prevent crushing.
To avoid leakages in the delivery line and get the best performance, ensure to seal the fittings with Teflon.
Remarks:
- All components of the pressure line must be compression-proof.
- All components of the pressure line must be professionally installed
- If the components are not compression-proof or if they are improperly installed, the pressure line could
burst during operation. Risk of injury from liquid spurting out!
