Pump
Electrical installation
WARNING
• The electrical installation may only be carried out by a qualified electrician in accordance
with the instructions provided with the pump.
• As electrical installation regulations differ from country to country, contactors, cables,
connection components, and enclosures must be selected based on local regulations.
• A main isolator must be installed before all live electrical connections on the pump.
This must be an all-pole isolator that satisfies the requirements set out in IEC/EN 60335-1
paragraphs 7.12.2, 22.2 and 24.3.
• The pump shall be fed via a residual current device with maximum leakage current of no
more than 30mA.
• The pump shall be fitted with an all-pole switch and approved automatic motor circuit
breaker that should be set to match the motor's rated current, see the pump motor rating
plate.
• Check that the pump's direction of rotation is the same as system flow – see the arrow on
the motor housing.
Operation
See that the pump is filled with water before start. The pump must never be dry run, as this could damage the shaft seal.
Check that all valves to and from the pump are open.
Do not run the pump with a closed valve, as this may cause damage to the pump.
The pump shall always be shut off before the position on the central valve is being changed (or other valves are being
closed).
The pump are not to work continuously with differential pressure to low (risk of cavitation).
Pump size H (m)
0.37– 4 .0kW at least 8 H(m).
5.5 – 7.5kW at least 10 H(m)
Risk of freezing
At the risk of freezing, the pump and the inlet and outlet pipes must be drained. Drain the pump completely by removing the
drainplug/drainplugs.
Check the pump motor rating plate which connec-
tion is applicable. Connect as shown below.
