2 INSTALLATION

2.1.1 INSTALLATION CONDITIONS

The unit must be installed according to national and local rules governing the use of electrical devices and according to the following guidelines:

- install the unit within residential buildings with ambient temperature between 0 ° C and 45 ° C;

- avoid areas in close proximity to sources of heat, steam, flammable and / or explosive and particularly dusty areas;

- install the unit in a place not subject to frost (the condensation water must be discharged not frozen, at a certain inclination, using a siphon);

- not install the unit in areas with a high relative humidity (such as the bathroom or toilet) to avoid condensation on the outer surface;

- choose an installation place where there is enough space around the unit for the air ducts and connections in order to perform maintenance;

- the consistency of the ceiling / wall / floor where the unit will be installed must be adapted to the weight of the unit and does not cause vibrations.

In the environment chosen for the installation must be present:

- connections of the air ducts;

- single-phase electrical connection 230V

- connection for the condensate discharge.

The unit is an integral part of a balanced ventilation system, with which the contaminated air is extracted from the kitchen, bathroom or any other local and introducing the same volume of fresh air in the living room or in the bedrooms. Gaps under the doors ensure a good circulation of air flow inside the home: make sure these gaps are never obstructed, such as para drafts or carpets, otherwise the system will not work optimally.

The simultaneous operation of the unit and a natural draft boiler (for example, Open fireplace) may cause a depression in the environment, which may occur due to a backflow of exhaust gas into the environment.


2.1.2 POSITIONING UNIT

VERSION H - Ceiling mount

For ceiling mounting unit, you must:

Place the 4 mounting brackets on the rear side of the unit and fix it with the screws supplied, after having carried out the holes with a drill (the holes must be drilled on the frame);

Attach to the ceiling unit, via the brackets, using appropriate anchoring systems (dowels, threaded rods, chains ...) and check the leveling with the aid of a spirit level.

Ensuring sufficient space for the performance of maintenance tasks: it must be guaranteed the opening of the cover of the unit (from the bottom).

Not mount the unit with the hips in direct contact with the walls to avoid possible noises from contact, insert strips of rubber or neoprene in this case.

Ceiling mount Brackets for ceiling mounting

2.1.3 DRAIN CONNECTION

Because of the heat recovery system (the hot exhaust air is cooled by placing inside the heat exchanger), the moisture contained in the indoor air will condense inside the unit.

For the proper functioning of the heat exchanger, it is therefore necessary to connect a condensate drain to the hydraulic system (exhaust) of the house. In addition, to enable the correct outflow of the condensate water, and avoid air eddies, the condensate drain must always be provided OF THE SPECIAL siphon supplied (on version V) units; on the H versions the installer to install a siphon;

To install the exhaust condensation adhere to the following standards:

• give a slope of at least 2% to the exhaust pipe;

• provide for the possibility to disconnect the drain pipe for maintenance (in particular in the case of ceiling installation);

• make sure that the discharge end of the tube is at least below the water level of the siphon;

• make sure that the siphon is always full of water.

Install the siphon condensate discharge of the unit ejection to avoid unpleasant odors in ambient air


3 AREAULICI CONNECTIONS

3.1.1 GUIDELINES AREAULICI

- Enter the password with the arrows (standard value 1) Scroll with the arrows up to the US parameter family: US 8 – Set Point Outdoor winter air US 15 – Outdoor summer air Set point

For example: If in winter the adjustment set point is at 20 ° the probe reads 16 °, the Unit should be activated with the compressor. But if the outside temperature is not below the US8 value the unit will still go in ventilation only. To exit the menu parameters PR1 Press Menu until the password insertion is reached and then press set and arrow with upward direction at the same time.
