The device is not adjusted to pump caustic, flammable, destructive or explosive
substances (e.g. petrol, nitro, oil, etc.), foodstuffs or salty water. Failures caused by
pumping of liquids other than pure water are not subject to warranty repairs.
The maximal temperature of the pumped water is 35
o
C.
The device is not adjusted to pump water containing excessive amounts of mineral
elements causing deposition of scale on the pumping elements. Operation in such
conditions results in premature wear and tear of the operating elements of the pump.
In such a case, only paid repair of the pump is available.
DEVICE INSTALLATION:
The device must be installed in a closed ventilated room, on levelled horizontal plane.
The room must be selected in such a manner, so that the device is not exposed to high
levels of humidity or frost.
It is prohibited to expose the device to impact of atmospheric factors (rain, snow).
Operation in such conditions as too high humidity levels can result in electrocution
hazard or failure of the motor or pressure switch. In case of such a failure, only paid
repair is available.
The power supply for the pump or booster set must be 230V/50Hz, with earthing.
The suction pipe must be connected to the pump by means of the suction port, using a
flexible non-collapsible hose (hose available for purchase from the guarantor), so that
the pipe stress is not transferred to the pump.
NOTE: do not use anti-vibration hoses in metal plait for connection of the pump and
suction pipe. This type of hoses can be used on the pumping side of the pump. Use of
such a hose on the suction side can cause sucking it in - jamming, closing the flow
through the hose and resulting in pump operation without water flow and, thus, in a
failure. This type of damage is not subject to warranty repair.
In case of ring wells, it is necessary to install a suction rose at the end of the suction
pipe with a check valve. For bored wells, the check valve must be installed directly
over the filter.
The length of the ring well must be selected in such a manner that the check valve and
the rose are at least 30 cm under the lowest possible water level and not lower than 30
cm from the well bottom.
It must be remembered that if the suction hose emerges during operation of the pump,
it will result in leakage in the suction system, causing operation of the pump without
water flow. Results of such a failure are not subject to warranty repair.
