5. START-UP AND OPERATION
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
cooling/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 temperatures
above 0
o
C. In low temperatures (below 0ºC) there is a danger of freezing
of the fluid.
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 lower than 0º, then
glycol solution should be used as the cooling/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 to the unit. Any modification
results in warranty loss.
Periodic inspections
To keep proper technical parameters Salvador Escoda SA recommends
periodic service (every 6 months) of fan heaters on behalf of the user.
During inspections user should:
Check heat exchanger, if is it filled dirty or dusty. If necessary - use
pressurized air stream to clean the exchanger’s lamellas,
Check fan blades, in case of dirt use damp cloth and remove dirt,
Check bracket installation,
Check heat exchanger and if the hydraulic connection has benn done
properly,
Check wires insulation,
Check power supply,
Check medium flow,
Check levelling of the unit.
Guidelines for System Connection
In the case of devices intended for cooling, control valves cutting off the
flow
of
the fluid
through
the
exchanger
should
be
used.
In
the
absence
of
a
cooling
signal,
the
valve
should
be
closed
to
avoid
overcooling the device.
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 near the device.
The system with the cooling/heating medium must be
protected against
an increase of the pressure above the permissible value (1.6 MPa).
While screwing exchanger to pipeline - connecting stubs has to be held.
