On first launch, the installation and pump must be carefully deaerated. When the
pump is deaerated, the level of the noise generated by the device motor drops.
Observe the following limitations:
Heating medium
temperature [
O
C]
Minimal inflow 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
When the surrounding temperature and heating medium temperature ratio is
incorrect, it can result in water steam condensation in the terminal box and
motor stator. In order to avoid it, it is essential to observe the following rule
at all times: the temperature of heating agent must be higher than the
temperature of surroundings. Minimal temperature of heating medium is
2
O
C.
The temperature of surroundings cannot exceed 30
O
C, and the maximum
temperature of heating medium is 110
O
C. When the temperature of surroundings is
40
O
C, the temperature of heating medium cannot exceed 70
O
C. For 35
O
C of
surroundings, the max. temp. of medium is 90
O
C.
Device destruction as a result of water steam condensation is not subject to
warranty repair.
The temperature of pump surface can never exceed 120
O
C. Device
destruction as a result of installation overheating is not subject to warranty
repair.
PUMP DISPOSAL:
The used product is subject to disposal as wastes only in selective waste
collection systems organised by the Network of Communal Electric and
Electronic Waste Collection Centres. The customer is entitled to return
the used equipment to the network of the electric equipment distributor,
at least for free and directly, if the returned device is of proper type and
fulfils the same function as a newly purchased device. It is prohibited to
dispose of electric equipment together with other household wastes.

Failure-free pump operation requires minimal inflow pressure of heating
medium (water) on the suction side of the pump. The minimal inflow pressure
depends on the heating medium temperature. The higher the temperature, the
higher inflow pressure must be provided on the suction side of the pump.
