INSTALLING THE INDOOR UNIT

USER

Before starting installation, decide on the position of the indoor and outdoor units, taking into account the minimum clearance required around the units (see technical data table).

Install the indoor unit in the room to be air conditioned, avoiding installations in corridors or communal areas.

Install the indoor unit at a height of at least 2.5m from the ground.

To install, proceed as follows: Installation of the mounting

• Drill 32mm deep holes in the wall for fixing the plate;
• insert the plastic anchors into the hole;
• fix the mounting plate using the self-tapping screws provided;
• check that the mounting plate is correctly fixed;
• using a spirit level, check that it is level.

Drilling a hole in the wall for the piping

• Decide where to drill the hole in the wall for the piping (if necessary) according to the position of the mounting plate;
• install a flexible flange through the hole in the wall to keep the latter intact and clean.

The hole must slope downwards towards the exterior.

Installing the refrigerant, electrical and condensate drainage pipes

Pass the pipe (for liquids and gas) through the hole in the wall from the exterior or install it from the indoor side, after having laid the pipes and connected the cables to the indoor unit, ready for connection to the outdoor unit.

Decide whether or not to remove the knockout according to the direction of the piping.

Water connections

Before installing the air conditioner, choose the direction for the pipes to exit; they may be arranged along any one of the 4 directions shown in the figure:

After having connected the pipe according to the instructions, install the drain hose. Now install the power cables. After connection, lag the pipe, cables and drain hose with the insulating material.

Lag the pipe joints with insulating material, securing it with vinyl tape.

Cover the through holes in the wall with elastic material that is also noise absorbing if possible.

Upon completion of installation, check that the condensate flows out regularly.

Lagging the pipes

Place the drain hose (not provided in the kit) below the piping, taking care not to create siphons.

Use polythene foam with thickness exceeding 6 mm to insulate the connections.

The drain hose must slant downwards to aid drainage.

Do not bend the drain hose or leave it protruding or twisted and do not put the end of it in water. If an extension is connected to the drain hose, ensure that it is lagged when it passes into the indoor unit.

If the piping is installed to the right, the pipes, power cable and drain hose must be lagged and secured onto the rear of the unit with a pipe connection.

I. Insert the pipe connection into the relative slot.
2. Press to join the pipe connection to the base.

Connecting the pipes

Use two wrenches to tighten the indoor unit pipe joints.

Pay particular attention to the torque recommended below in order not to risk deforming and damaging flared pipes, connectors and nuts.

Tighten the connections using two wrenches working in opposite directions (see technical data table).

Electrical connections

The terminal blocks on the units must be accessed to carry out the electrical connections.

See the pictures at the side.

To ensure correct size of the wires for the electrical connection and for connecting the units together, see the technical data table.

For the electrical connections, see the circuit diagram inside the access flap and refer to the information given in this manual.

The cable connecting the outdoor and indoor units must be suitable for outdoor use.

The plug must be accessible also after the appliance has been installed so that it can be pulled out if necessary.

Installation of an omnipolar thermomagnetic line-disconnecting switch to CEI-EN standards (with contact separation of at least 3mm ) near the appliance is compulsory.

An efficient earth connection must be ensured.

If the power cable is damaged, it must be replaced by an authorised Service Centre.

Under no circumstances should gas or water pipes be used for earthing the appliance.

Upon completion of connections, secure the cables with cable glands and replace the terminal block covers.

Failure to comply with these instructions and accident-prevention regulations relieves the manufacturer from all liability.

WIRING DIAGRAMS FOR

CONVERTER

MODELS

Ensure that when connecting the indoor and outdoor units, the numbering on the respective terminal blocks is observed.

We suggest the installation of RCD device with nominal differential current that doesn't exceed the 30mA

INSTALLING THE OUTDOOR UNIT

INSTALLER

Location

Use bolts to secure the unit to a flat, solid floor. When mounting the unit on a wall or the roof, make sure the support is firmly secured so that it cannot move in the event of intense vibrations or a strong wind.

Do not install the outdoor unit in pits or air vents

Installing the pipes

Use suitable connecting pipes and equipment for the refrigerant in the appliance (see rating plate).

The refrigerant pipes must not exceed the maximum lengths given in the technical data table.

Lag all the refrigerant pipes and joints.

Tighten the connections using two wrenches working in opposite directions.

Install the drain fitting and the drain hose (for model with heat pump only)

Condensation is produced and flows from the outdoor unit when the appliance is operating in the heating mode. In order not to disturb neighbours and to respect the environment, install a drain fitting and a drain hose to channel the condensate water. Install the drain fitting and rubber washer on the outdoor unit chassis and connect a drain hose to it as shown in the figure.

Do not install the outdoor unit where it is exposed to sunlight.

Ensure that the recommended space is left around the appliance.

Humid air left inside the refrigerant circuit can cause compressor malfunction. After having connected the indoor and outdoor units, bleed the air and humidity from the refrigerant circuit using a vacuum pump.

(1) Unscrew and remove the caps from the 2-way and 3-way valves.
(2) Unscrew and remove the cap from the service valve.
(3) Connect the vacuum pump hose to the service valve.
