Operation
Before use, check that the values of the socket to which you wish to connect the
pump correspond to those on the type plate on the pump itself (230V-50Hz) and
that the socket is earthed (max. 30mAmp) and has an earth leakage circuit breaker
(nominal voltage ≤30 mA). Make sure that no people present in the space to be
pumped out (cellar/boat/pond etc).
Automated function
Once you have plugged the device into the socket, the pump will switch on
automatically when the water exceeds the set minimum level and switch off when
the set minimum level has been obtained.
This means that the pump can be left on at all times and will keep the water in a
cellar or boat, for example, at the required level. Bear in mind that this pump is not
designed to be used continuously; it must be switched off at regular intervals.
Despite the fact that the pump works automatically, regular supervision is required
in order to ascertain that it has not encountered any functional problems and that it
has not been damaged (see also: overheating safeguard).
Manual function
If used manually, your pump will start to work when you insert the plug into the
socket and you ensure that the float switch is set to 'on'. You do this by holding the
float switch upright (float cable underneath). The pump will continue to work if you
hold the float in this way (or fix it like this). Stop the pump from functioning as
soon as liquid is no longer being pumped; the pumped liquid also cools the motor
and without this cooling effect it may overheat and break down! Always supervise a
pump that is working manually; drying out will lead to increased wear and tear!
If your pump has run dry it will not automatically aerate itself. Switch it off (remove
the plug from the socket) and move the pump from side to side so that air can
escape. Thereafter, you may use the pump as usual. You are advised to use the
pump manually for short periods only. You should keep your eye on the pump at all
times during manual functioning.
During automatic operation, the pump will turn itself off when there is still some
water in your cellar/boat/pond because the automatic float switch needs space in
which to switch. If you wish to pump out the remaining water, we advise you to use
the pump manually in order to do so. Placing the pump at the lowest point (or in a
hollow) will allow you to remove almost all of the remaining water. Make sure it
does not dry out!
Overheating safeguard
Your submersible pump is equipped with an overheating safeguard. This switches
the pump off automatically if the motor gets too hot. Once it has cooled down
sufficiently, the pump will automatically switch on again.
There is always a cause for overheating: the fan may have become jammed, a
bearing may be worn etc. etc. and if the cause is not removed, the device will
