4. Delivery set
Circulating pump - 1 pc.
Fitting with nut - 2 sets.
Instruction Manual - 1 pc.
Packaging - 1 pc.
5. Design and operation principle
The pump is equipped with the motor that has a “wet rotor” , isolated from the stator by sealed
sleeve. The pump uses shaft and radial bearings made of ceramic, axial bearing made of
graphite. Bearings are lubricated with the pumped liquid. The protective sleeve of the rotor and
the bearing plate is made of stainless steel, impeller is made of technical polymer, the pump body
made of brass.
Three-way switch changes the motor speed and optimizes the intensity of the circulation of the
coolant in the system.
The pump is equipped with thermal protection, to prevent possible overheating of the pump as a
result of blocking of the impeller.
6. Installation, putting into operation and maintenance
Installation of the pump, putting into operation, maintenance and repair should be carried out by
authorized organization (professional). Execution of works should be formalized by special
document.
Installation of the pump should be made after installation and cleaning of the heating system. The
pump has a threaded flange for connection to the system. Connection should be made with the
help of fittings with cap nuts and washers, supplied with
The arrow on the pump housing indicates the direction of movement of coolant. The pump shaft
must be located in a horizontal plane. Connection of the pump has to be made through residual
current device with the current response that does not exceed 30 mA. To ensure all-pole
disconnection from the mains connection of the pump should be carried out through a two-pole
switch with a contact separation of at least 3mm in all poles, connected directly to the power
terminals and mounted in the fixed wiring.
Before starting the pump operation it is necessary to fill the system with coolant and remove air
from it. To achieve the required speed, use the three-way switch of pump speed.
7. Troubleshooting
Table 2
Design of the products or delivery set may be amended and not indicated in this instruction
manual. However these changes do not impair the quality of the product.
Malfunction Reason Troubleshooting
The pump is not working There is no power Check the power supply
The pump is not pumping water
or a very small stream of water
Lock of the pump bearings
Contamination of the pump
Remove the pressure in the system.
Loosen the screw on the front side of the
stator. Turn the shaft with a screwdriver.
There is no coolant in the heating
system
Fill the heating system with coolant. Open
valves
The pump makes noise The air in the pump Remove air from system
Low voltage of power supply Set the voltage stabilizer
