MANUAL OF ENERGY-SAVING CIRCULATION PUMP
Ψ PSI
EEI≤20
Precautions on use of PSI series pumps
1.
Before installation, read the following manual carefully
2.
Failure to observe the fragments marked with warning signs may cause bodily injury, pump
damage and other property losses, for which the producer takes no lability, including but not
limited to liability for damages.
3.
The fitter, maintenance technician and user have to observe the local safety
regulations.
4.
The user must confirm that the installation and maintenance of the product are performed
by personnel having adequate knowledge and professional experience connected with the
structure and operation of heating systems.
5.
Pumps cannot be installed in moist environment or in places which can be exposed
to flooding with splattering water.
6.
To make maintenance easier, place a ball valve on both sides of the pump.
7.
During installation and maintenance, cut off the electric power supply from the pump.
8.
The central heating circuit cannot be frequently refilled with non-softened water to avoid
accumulation of scale in the pipeline. High accumulation of scale can block the rotor of the
device.
9.
The pump cannot be run without a heating medium.
10.
If the pump is dismounted from the pipeline, either discharge the heating medium from the
system or close the ball valves cutting the pump off before dismounting to avoid possible
burning with the heating medium. Please remember that the heating medium can have
high temperature and pressure.
11.
In dismounting the pump from the pipeline, the heating medium, which can have high
temperature and high pressure, will flow outside. Please be careful not to cause bodily
injury due to burning and not to flood other devices.
12.
In summer or when the ambient temperature is high, pay attention to proper
ventilation in the room where the pump has been installed. It will help prevent
condensation of humidity, which can cause an electric failure.
13.
In winter, if the central heating system where the pump has been installed does not work
and the ambient temperature is below 0 ° C, discharge water from the heating system.
Please bear in mind that freezing water can burst the pump body.
14.
If the pump does not operate for a long time, close the ball valves cutting off the pump and
cut off electric power supply.
15.
If the electric wire powering the pump is damaged, refer to an authorised
servicing team to replace it along with its switch.
16.
If the pump motor heats up excessively (more than usually), immediately disconnect the
pump from its power source, close the cut off valves and contact a servicing team.
