- Before connecting the power supply check the correctness of connection of the fan motor and the
ontrollers These connections should be executed in accordance with their technical documentation.
- Before connecting the power supply check whether the mains voltage is in accordance with the voltage
on the device data shield.
- The electrical system supplying the fan motor should be additionally protected with a circuit breaker
against the effects of a possible short-circuit in the system
- Starting the device without connecting the ground conductor is forbidden.
- The connection should be executed in a way which does
not induce stresses. It is recommended to use flex pipes to
connect the stubs.
- It is recommended to install vent valves at the highest point
of the system.
- The system should be executed so that, in the case of a
failure, it is possible to disassemble the device. For this
purpose it is best to use shut-off valves just by the device.
- The system with the heating medium must be protected
against an increase of the heating medium pressure above
the permissible value (1.6 MPa).
- While screwing exchanger to pipeline - connecting stubs
has to be hold by wrench.
- The device is designed for operation inside buildings, at temperatures above 0
o
C. In low temperatures
(below 0ºC) there is a danger of freezing of the medium.
- The manufacturer bears no responsibility for damage of the heat exchanger resulting from freezing of
the medium in the exchanger. It is forbidden to place any objects on the heater or to hang any objects
on the connecting stubs.
- The device must be inspected periodically. In the case of incorrect operation of the device it should be
switched off immediately.
- It is forbidden to use a damaged device. The manufacturer bears no responsibility for damage
resulting from the use of a damaged device.
- If it is necessary to clean the exchanger, be careful not to damage the aluminium lamellas.
- For the time of performing inspection or cleaning the device, the electrical power supply should be
disconnected.
- In case water is drained from the device for a longer period of time, the exchanger tubes should be
emptied with compressed air.
