F) ELIMINATION OF AIR WITH THE PUMP
OF THE VACUUM (Fig 8)
Air and moisture in the refrigeration system can
cause side effects as shown below:
To avoid the above, the internal assembly and the
tubes, places between internal and external group,
must be tested for leaks and purged to remove non-
condensing elements and humidity from the system.
Check that each tube, (is the gas side tubes that of the
liquid) between internal group and external group, has
been connected in the correct way and that all wiring
necessary for testing have been carried out. Remove
the valve cap on the assembly external. Make sure that
both are now gas and liquid valves remain
closed.Check the length of the tube and its quantity of
the refrigerant for a correct charge, check the
overheating value.
Fig. 8 ATTENZIONE! WARNING!
To make sure to perform the
procedure of emptying with
the group in COLD MODE.
- Increased pressure in the system.
- Increased current consumption.
- Decreased refrigerant efficiency.
- Freezing and obstruction of the pipes
capillaries.
- Corrosion of the parts of the system of
refrigeration.
When you change places in the unit, carry it out
bleeding with the vacuum pump. Make sure the
refrigerant inside the conditioner is always
in liquid state.
External units are supplied with a charge of
R410A refrigerant gas suitable for guaranteeing
correct operation
operation up to a maximum distance of 5
meters from the indoor unit.
If you decide to install the 2 units at one
distance greater than 5 meters, be sure to add
20 g of refrigerant gas per meter more than
piping (Tab. 3).
For example, if there are external and internal units
7 meters of piping add 40 g of R410A gas.
In any case, never exceed 15 meters.
Do the addition only after making the
vacuum in the pipes that connect the 2 units, such
as illustrated in chapter 3.4, after which you can
proceed with the opening of the gas taps, mounted
on board machine.
G) EVACUATION
Connect the end of the charging hose to the
vacuum pump to evacuate the air from the pipes
of the internal unit. Check that the knob
"LO" of the pressure gauge valve is open.
Then run the vacuum pump. The time of
operation varies depending on the length of the
tubes and pump capacity.
When the desired vacuum is reached, close
the "LO" knob on the pressure gauge valve e
stop the vacuum pump. In conclusion, using
a wrench for service valves, rotate the stem
of the gas side valve counter clockwise for
open it completely.
Loosen the charging hose connected to the socket
gas side service to relieve pressure, then
remove the tube. Replace the cover nut on the
gas valve and service outlet and tighten
well with an adjustable wrench.
This procedure is very important to avoid
plant leaks Replace the service valve caps either
on the gas side than on the liquid side and tighten
well.
This completes the air purge procedure
with the vacuum pump, make sure all the pipes
are connected correctly and that the valves of
service of the gas and liquid sides are completely
open.

anchoring system to the wall itself, in function of the
weight of the appliance to be installed.
- Do not install the appliance near sources
of heat and / or areas with fire hazards.
- Installation in highly atmospheric areas
corrosive is not allowed; in condition particular
climatic conditions such as near the sea, it is
mandatory to provide for a duration of
lower life of the product and in any case more
frequent and accurate maintenance.
- In external units, from which it is eliminated
condensation water, provide a special one
drainage and / or channelling of the same, in
so as to avoid dangerous situations
due for example to ice formation
on transit areas.
- The outdoor unit is designed to be installed
outdoors and does not require a base
special, however it must be positioned
safely on a support surface
horizontal of adequate bearing capacity e
equipped with special anti-vibration pads.

Fig. 7
In this regard, we advise, if necessary, to do
install a kit made of a compressor cover
complete with upper headphone, sound-absorbing
insulation
on the inside of the compressor compartment and
up
all the inside of the top cover (see
accessory cod. 75100001)
Very important, then, is the installation of systems
that
is combined with the heat pump for this purpose
the following aspects must be considered.
1) POSITIONING OF THE EXTERNAL UNIT
Positioning has an important influence
on sound emission, not to mention cases
in which the outdoor unit is positioned in a loggia
or in a porch, in these cases we have 14 dB (A)
extra that add up to the normal
machine emission.
3.4 ACOUSTIC REQUIREMENTS
During the installation phase of a HUB heat pump
RADIATOR is to be evaluated very carefully where
the external unit is positioned in order to avoid
induced noise that goes beyond the tolerability
threshold. The external evaporating motor unit
during work phase generates external sound
emissions and requires appropriate measures to
reduce the incidence of noise produced by the
compressor and / or fan.
1)POSITIONING OF THE EXTERNAL UNIT

14
2) CHOICE OF ANTI-VIBRATION SUPPORTS TO MAKE OBLIGATORY ON THE ARMS
OF SUPPORTING THE OUTDOOR UNIT, OR ON THE FLOOR IF STORED TO THE GROUND WITH
ANTI-VIBRATION FLOOR BASE
N.B. . it is advisable to place the outdoor unit where possible, always resting on the ground.
Anti-vibration mount on shelf
anti-vibration kit
Anti-vibration support on the floor
anti-vibration floor base
Codice 75100021 Codice 75100018
3) IN THE POSITION OF INSTALLATION ON A SHELF, AVOID FIXING ON
EXTERNAL WALLS OF THE NIGHT AREA AND AVOID FIXING THE SHELF IN
PROXIMITY OF BEAMS OR PILLARS THAT MAY GENERATE ALSO VIBRATIONS
INSIDE THE BUILDING.
YOU MUST ALWAYS APPLY RUBBER BANDS (THICKNESS 3 mm) HOW
ANTI-VIBRATION BETWEEN THE SHELF AND THE WALL OF THE EXTERNAL WALL.
THE SUPPORT BRACKETS MUST ALWAYS BE INSTALLED IN PERFECT
LEVELING DISTANCE FROM THE BOTTOM WALL OF ABOUT 15 cm.
4) APPLICATION OF DAMPING MASSES ON REFRIGERANT GAS PIPES THAT
THEY MAY GENERATE VIBRATIONS BY SENDING THE SYSTEM TO RESONANCE.
IN RELATION TO THE REFRIGERANT GAS PIPE, MAKE SURE THAT THE CHARGE
DI GAS IS ALWAYS CORRECT AS SHOWN ON TARGA DATA.
THE EXTERNAL UNIT TOO MUCH OF GAS GENERATES AN INCREASE OF ABSORPTION
ELECTRIC AND AN INCREASE OF NOISE INDUCED INDIVIDUAL COMPRESSOR.
5) IT IS NECESSARY TO REMEMBER THAT THE PERCEPTION OF THE NOISE DEPENDS VERY MUCH
NOISE LEVEL PRESENT IN THE AREA.
FROM SPECIFIC STUDIES MADE BETWEEN THE DAY AND THE NIGHT PERIOD LA
PERCEPTION OF THE SAME NOISE INCREASES BY 10 dB (A) WHEN THE OUTDOOR UNIT
WORK IN NIGHT HOURS.
IT IS RECOMMENDED FOR THIS PURPOSE TO INSTALL A CLOCK KIT THAT ALLOWS YOU TO
AVOID THE OPERATION OF THE EXTERNAL UNIT AT FULL NIGHT
(SEE CODE 35639900 ACCORRONI TECHNOLOGY).
6) THE PERCEPTION OF THE NOISE IS SUBJECTIVE AND VARIES ACCORDING TO THE THRESHOLD OF
INDIVIDUAL TOLERABILITY AND BASED ON THE DISTANCE BETWEEN THE ISSUE SOURCE
AND THE RECEIVER.

7) ON THE 2017 TECHNOLOGY IN EXIT IN NEXT MARCH WE HAVE REPORTED
AS NEW IN THE ACCESSORIES, ABOUT NOISE, THE FOLLOWING DEVICES
ACTI TO ALSO AVOID NOISE TRANSMISSION INDUCED BY IN PIPES
