SPV550 semi PI – SPV750i – SPV900i – SPV1100i: Your pump is fitted with automatic
-
aeration, allowing air to escape when it is submerged in water. The air bubbles that appear
are not a sign of a defect but are perfectly normal.
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). 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).
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!
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.
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 overheat once again. If this
process is repeated too often it may cause serious damage to your pump. Try to establish what
is wrong and resolve the problem. If the pump needs to be opened up you must take it to your
supplier or an accredited professional.
