Guidelines for System Connection
The connection should be executed in a way which does not
induce stresses.
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.
Start Up
Before connecting the power supply check the correctness of
connection of the fan motor and the controllers. 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
plate.
Before starting the device check the correctness of connection
of the heating medium conduits and the tightness of the
system.
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.
Operation
The device is designed for operation inside buildings, at
o
temperatures above 0 C. In low
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. If operation of the device is expected at
temperatures l
used as the heating medium, or special automatic systems
should be used for protecting against 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.
It is not allowed to make any modification in the unit. Any
modification causes in warranty loss.
