In order to avoid the above, the indoor assembly and pipes, placed
between the indoor and outdoor assemblies, must be tested
for leaks and purged to remove non-condensing elements and
moisture from the system. Check that each pipe (both the gas and
liquid side pipes) between the internal and external groups has
been connected correctly and that all the wiring required for testing
has been carried out.
- Remove the valve cap on the outdoor assembly.
- Make sure that at this point both the gas valves and the
liquid remain closed.
- Check the length of the hose and the relative amount of
refrigerant, for correct charging, check the superheat value.
When changing the location of the unit, bleed with the vacuum
pump.
Make sure that the refrigerant inside the air conditioner is always in
a liquid state.
The outdoor unit is supplied with a charge of R410A refrigerant gas
suitable for ensuring proper operation up to a maximum distance of
5 meters from the indoor unit.
If you decide to install the 2 units at a distance greater than 5 meters,
be sure to add 20 g of refrigerant gas for each additional meter of
piping (table 4).
For example, if there are 7 meters of piping between the outdoor
and indoor units, add 40 g of R410A gas.
In any case, never exceed 15 meters.
Add only after vacuuming the pipes connecting the 2 units, after
which you can proceed with opening the gas taps, mounted on the
machine.

3.5 EVACUATION
Connect the end of the charging hose to the vacuum pump to
evacuate the air from the pipes of the indoor unit. Check that the
“LOW” knob of the pressure gauge valve is open.
Then run the vacuum pump.
The running time varies depending on the length of the pipes
andthe capacity of the pump.
When the desired vacuum is reached, close the “LOW” knob of
the pressure gauge valve and stop the vacuum pump.
Finally, using a service valve wrench, turn the gas side valve
stem counterclockwise to fully open.
Loosen the charging hose connected to the gas side service port
to relieve the pressure, then remove the hose.
Replace the gas valve and service plug cover nut and tighten
securely with an adjustable wrench.
This procedure is very important to avoid system leaks.
Replace the service valve caps on both the gas and liquid side
and tighten well. This completes the air purge procedure with the
vacuum pump, make sure that all pipes are connected correctly
and that the service valves on the gas and liquid sides are
completely open.

3.7 PUMP DOWN
This procedure is carried out when the unit needs to be moved or
assistance is carried out on the refrigerant circuit.
Emptying allows all the refrigerant to be collected in the outdoor
unit without leaks.
3.8 RECOVERY PROCEDURE
- Connect a low pressure gauge with a hose to the gas valve
service socket.
- Half open the gas valve and empty the air from the pipeline
pressure gauge using refrigerant gas.
- Close the liquid valve completely.
- Turn on the machine in cooling mode.

4.4 AIR INTAKE / SMOKE EXHAUST SYSTEM
A modulating high efciency condensing boiler is located in the
indoor unit of the HUB RADIATOR PACK CF hybrid system.
As regards the discharge of fumes into the atmosphere and the
air intake / fumes exhaust systems, comply with the laws and
regulations in force, which are understood to be fully transcribed
here.
Safety devices are installed on the boiler to control the evacuation
of combustion products.
In the event of a malfunction of the air intake / ue gas exhaust
system, the devices put the boiler in safety and the code E14
ashes on the LCD display.
Tampering with and / or exclusion of these safety devices is
strictly prohibited.
In the event of repeated shutdowns of the boiler, it is necessary
to have the air intake / ue gas exhaust ducts checked, which
could be obstructed or inadequate for the disposal of fumes into
the atmosphere.
For the air intake / ue gas discharge, the specic ducts and
systems for original condensing boilers must be used, resistant
to the attack of condensate acids.
The exhaust pipes must be installed with a slope towards the
boiler such as to guarantee the reux of the condensate towards
the combustion chamber which is built to collect and discharge
the condensate.
If this is not possible, it is necessary to install systems capable
of collecting and conveying the condensate to the condensate
drainage system in the condensate stagnation points.
It is necessary to avoid condensation stagnation points in the
combustion products evacuation system, with the exception
of the liquid head of any siphon connected to the combustion
products evacuation system.
The manufacturer declines all responsibility for damage caused
as a result of installation, use or transformation errors
of the appliance or for failure to comply with the instructions
provided by the manufacturer or the installation standards in
force concerning.

autonomously performs a cycle at minimum power “P0”,
ignition “P1” and at maximum power “P2” to obtain good ame
stability, then goes into mode CO2 modication to allow manual
calibration.
The setting of the type of mode (AUTO or MANU) is entered in
the activation code for parameter “P14” in the TSP Parameters
menu.
TSP parameters that can be set from the interface and from the
Remote Control.
The AUTO mode is the recommended one and which allows the
greatest freedom to modify the CO2.
OPERATIONS TO BE PERFORMED
Enter the chimney sweep function and check that the CO2 value
is within the limits of Table 11 both at maximum (Hi) and minimum
(Lo) power (if the system temperature rises excessively, it is
possible to open the DHW cocks to dispose of the heat; it is not
possible to start the procedure with the DHW open).
If not, proceed as described below.
Press the keys simultaneously for the cycle time “
MODE
” and
“
RESET
”. Release then immediately (within 2 seconds) press one
turn the button “ ”.
The card conrms the activation of the function and shows on
the display “Au-to” or “Ma-nu” depending on the dened setting
mode.
The board will internally generate a request for operation in
“calibration” mode and will start the power-up sequence.
If the function is active “Au-to”, the ashing of the “radiator”
symbol is also activated.
Once ignition has been completed, the boiler will perform a
parameter storage cycle at maximum power, then at ignition
power and, nally, at minimum power.
During this phase, the LCD display cyclically shows the cycle
time and the ow temperature.
At this point, the ue gas analyzer probe can be inserted into the
exhaust duct.
4.7 ADAPTATION TO THE USE OF OTHER GASES AND ADJUSTMENT OF THE BURNER
The boilers are produced for the type of gas specically
requested when ordering, which is shown on the packaging
plate and on the boiler technical data plate.
Any subsequent transformations must be carried out
strictly by qualied personnel, who will use the accessories
appropriately prepared by the manufacturer and will carry
