APPLICATION:
Pumps described in this manual are intended for forcing circulation in central
heating installations with constant or variable flow in which the temperature of
heating medium does not exceed 110
o
C, and pressure in the installation does not
exceed 1 Mpa (1,000,000 Pa). The maximum temperature of the surroundings
where the pump will be installed cannot exceed 40
o
C, and relative moisture at the
installation site must be lower than 90%.
PUMP INSTALLATION:
Prior to any installation works, power supply must be
disconnected. Provide security against accidental switch-on.
The pump can be connected upon completion of all installation works in the
pipeline where it will operate. One should remember that, as a result of
welding or soldering works, mechanical contamination can be accumulated
in
2
The pumped water cannot contain any mechanical contamination. The
pump is intended for pumping of clean water, with no
solid or abrasive particles. Pumping water containing mechanical contamination
results in fast wear and tear of the pump and, in consequence, it its failure. In such
a case, only paid repair is available.
The pump is not adjusted to pump caustic, flammable, destructive or explosive
substances
(e.g. petrol, nitro, oil, etc.), foodstuffs or salty water. Failure caused by pumping of the
same type of liquid is not subject to warranty repair.
The maximal temperature of the pumped water is 110
o
C.
The pump is not adjusted to pump water containing excessive amounts of
mineral elements causing deposition of scale on the pumping elements. Using
the pump 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.
The pump cannot pump water containing oils and petroleum derivatives.
Pump operation in such water can lead to destruction of rubber elements,
e.g. cables or sealing, and result in leakage in the pump and motor failure. In
such a case, only paid repair of the pump is available.
