10.0 STARTING
10.1 INSPECTIONS
Before starting operation, make sure that the rules
and regulations on the installation of these devices,
especially with respect to the correct sizing of the
water supply pipes have been complied with.
Before proceeding with the commissioning of the
device must ensure that:
- security conditions and all the instructions contained
in this manual have been complied with;
- securing the support bracket to the wall is stable and
clear zones are free from any obstacle or materials,
which hinder the easy accessibility of the apparatus;
- plumbing and electrical connections, with particular
attention to the ground, they have been properly
executed;
- the devices for loading, unloading and vent the
system are in the correct operating conditions and
have been adequately controlled;
- was made a thorough bleed air from inside of water
pipes and the heat exchanger unit
10.2 CHECKS
Dare tensione tramite l'interruttore omnipolare di
cui al precedente punto 3.3. Se l'apparecchio è
comandato da un termostato ambiente, posizionare
il dispositivo di regolazione dello stesso sul valore di
temperatura che si desidera raggiungere in ambiente
e, se il termostato è completo di commutatore delle
tre velocità di ventilazione, controllarne il corretto
funzionamento.
10.3 INFORMAZIONI ALL'UTENTE
Powering through the pole switch referred to in
paragraph 3.3. If the unit is controlled by a room
thermostat, set the adjustment device of the same
on the temperature value you want to achieve in the
environment and, if the thermostat is complete switch
of the three-speed fan, check its correct functioning.
11.0 FAULTS OF OPERATION
11.1 PRELIMINARY CHECKS
Before performing specific tests, make sure:
A) power supply is properly connected and any
external regulation bodies such as the room
thermostat or timer, are operating properly;
B) the shut-off valves, mounted on the water pipes,
are in the open position.
11.2 POSSIBLE DEFECTS
Here are the possible faults with the list of possible
causes. In italics are briefly indicated repair or restore
operations, which are the responsibility of skilled
technical personnel.
11.3 FANS DO NOT WORK
A) The control systems and external control of the
equipment are dead (thermostats, on / off and the
like);
- Verify correct operation.
B) The connection of power cables fan is damaged
or broken;
- Restore the wiring correctly. Verify that the
motor is not burned and in case replace it.
11.4 LOSS OF WATER FROM THE BATTERY
A) Water connections are not made correctly;
- Restore the hydraulic connections ensuring
the tightness of suitable materials.
B) The exchanger has corrosion and / or lost estate;
- Replace the heat exchanger with a new one,
still looking for any external cause of the
problem (presence of corrosive atmosphere or
aggressive substances in the environment)
11.5 FAN STOPS EVEN IN THE SITUATION
OF OPERATING REQUESTA)
The motor thermal protection activated
- Verify, through the use of an ammeter, that
the absorptions of the motor does not move
too much from the rated values, identify the
cause of overheating and possibly replace the
fan.
11.6 NOISE OR VIBRATIONS DURING
OPERATION
A) The fan is noisy and / or vibrating
- Check the correct rotation of the fan blades
and the presence of possible frictions. Remove
any dust deposits. Check the tightening of the
screws that secure the motor to the grid and
the grid itself appliance.
12.0 REPLACEMENT PARTS
For the replacement of components is required
specific technical skills, so it is recommended
to alert the user to always contact an authorized
Technical Service Centre.
