APPLICATION:
The pumps which this operating manual applies to are used to enforce
circulation in central heating installations with constant or variable flows, where
the heating medium temperature does not exceed 110
o
C and the installation
pressure does not exceed 1Mpa (1 000 000Pa). The maximum ambient
temperature in the pump installation area must not exceed 40
O
C and the relative
humidity must be less than 90%.
The pumped water must not contain mechanical impurities.
The pump is designed to pump water which does not contain solids or abrasive
particles. Pumping water with mechanical impurities will shorten the pump’s
service life and may lead to its failure. This type of equipment damage is not
covered by the warranty and any repairs will have to be paid for.
The pump is not designed to pump substances which are corrosive, flammable
or have damaging or explosive properties (for example petrol, nitro, petroleum,
etc.), as well as foodstuffs and salt water. Equipment failures caused by this type
of damage are not covered by the product’s warranty.
The maximum temperature of pumped water is 110
o
C.
The pump is not adapted to pump water with an excessive level of mineral
particles, as this causes lime scale to build up on the pumping elements. Such
operating conditions will shorten the pump’s service life. This type of equipment
damage is not covered by the warranty and any repairs will have to be paid for.
The pump must not pump water which contains oils and petroleum derivatives.
If the pump operates in such conditions, it may lead to the damage of rubber
elements such as cables or seals, and as a result the pump may become unsealed
and the motor may become damaged. This type of equipment damage is not
covered by the warranty and any repairs will have to be paid for.
