ATTENZIONE! WARNING! To make sure to perform the procedure of emptying with the group in COLD MODE.

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.

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 noncondensing elements and humidity from the system.

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.

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.

This procedure is performed when the group must be moved or assistance is provided to the refrigerant circuit.

3.1 GENERAL

In choosing the installation position accurately respect the following indications:

- Make sure that the difference between INTERNAL

UNITS and the OUTDOOR UNIT is not greater than 5.0 m.

- The appliance must be installed so

that the influences of adjacent structures and / or i effects of particular climatic conditions (snow, wind etc ...), do not compromise the functioning of the product and / or the safety of people e of assets.

- Make sure the space in the back

unit is greater than 30 cm, the part front must have at least 150 cm of space completely free.

- Make sure there are no obstacles to the

free circulation of air through the heat exchangers: A) do not arrange plants or animals directly close to the stream air; B) avoid installation in the corners where it is used the depositing of dust, leaves and whatever can reduce the efficiency of the exchangers obstructing the passage of air (Fig 5).

Page 12

Fig. 5

- Avoid installation in tight and small spaces get away because they could be favored acoustic reverberations. Inquire about the any limits on expected noise emissions for the area of the municipal territory in which it is install the appliance. In case of doubt it is it is advisable to consult a acoustic technician, qualified for an evaluation of the impact, to prevent disputes from third party.

- Prevent the air expelled by the fans penetrate through adjacent doors and / or windows, causing disturbance to people.

- Install the external units on a rigid base equipped with special anti-vibration pads to avoid the increase of vibrations and noise, so as not to disturb the neighbours (Fig.6).

- If the appliance must be suspended on one external wall, the support must respect the Technical specifications. The wall where the unit should be installed, must be brick or material of similar consistency, otherwise it must be reinforced. Support brackets must be stable, durable and with adequate degree of protection against corrosion. WARNING! Make sure of bearing capacity of the part on which the shelves are placed and of the 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.

3.2 DISTANCES OF RESPECT (Fig. 7) Respect the spaces indicated in figure 8, in such a way to allow correct operation and all installation and maintenance operations.

Fig. 6

- Position the outdoor unit so that the air flow is not hindered in any way. In the case of strong winds, make sure the fan functions correctly, positioning the unit longitudinally, along a wall or using a shield.

3.3 ROOF INSTALLATION

- If the outdoor unit is installed above a roof, be sure to level the unit. Make sure that the roof structure is appropriate for mounting unit.

- Consult the local codes regarding the roof mounting.

- If the outdoor unit is installed on the roof or on the external walls, this could cause excessive noise and vibration and being classified as an unsuitable installation at service. on the ground, free installation + 3 dB (A) in a recessed corner of the facade + 9 dB (A) against the facade + 6 dB (A)

Fig. 7

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

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.

Page 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

Codice 75100021 Codice 75100018

N.B. . it is advisable to place the outdoor unit where possible, always resting on the ground.

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.
