For the pump to operate correctly, there must be a minimum inlet
pressure of the heating medium (water) on the suction side of the pump.
The minimum inlet pressure of the medium is dependent on the temperature of
the medium. The higher the temperature, the higher the inlet pressure of the
heating medium on the suction side of the pump should be.
The following limits must be observed:
Heating medium
temperature [
O
C]
Minimum inlet pressure on the
suction side [bar] / [m] / [Pa]
≤ 75
0.05 bar / 0.5 m / 5 000 Pa
90 0.28 bar / 2.8 m / 28 000 Pa
110 1.08 bar / 10.8 m / 108 000 Pa
An incorrect ratio of the ambient temperature to the heating medium
temperature may result in water vapour condensation in the terminal box
and in the motor stator. To prevent this from happening, the heating medium
temperature must be higher than the ambient temperature. The minimum
temperature of the heating medium is 2
O
C.
With the ambient temperature of 30
O
C, the maximum temperature of the
heating medium is 110
O
C. With the ambient temperature of 40
O
C, the maximum
temperature of the heating medium is 70
O
C. With the ambient temperature of
35
O
C,
the maximum temperature of the heating medium is 90
O
C.
Any equipment damage caused by water vapour condensation is not covered by
a warranty.
The surface temperature of the pump must not exceed 120
O
C.
Any equipment damage caused by the installation overheating is not
covered by the warranty.
STORAGE AND TRANSPORT:
The pump must be stored in a dry area and protected from damp. During
transport, the pump should be protected from damp and mechanical damage.
DISPOSAL OF THE PUMP:
Waste equipment must be disposed of as waste collected selectively
by the Municipal Network of Electrical and Electronic Waste
Collection Points. The consumer is entitled to return waste equipment
to the equipment distributor, free of charge and directly, if the
returned items are of the correct type and have the same function as the newly
purchased products. It is prohibited to dispose of waste electric equipment
together with other house municipal waste.
