Installation manual

4

Prepare the installation of the fan coil unit

3.5.

Prepare the electrical wiring work

The unit must be connected to the power supply. All field wiring and 
components must be installed by an installer and must comply with the 
applicable legislation.

Before connecting the electrical wiring, check the following points:

Q

use copper wires only,

Q

all field wiring must be carried out in accordance with the wiring 
diagram delivered with the unit,

Q

never squeeze bundled cables and be sure that cables do not 
come in contact with the piping and sharp edges. Be sure no 
external pressure is applied to the terminal connections,

Q

be sure to establish an earth. Do not earth the unit to a utility pipe, 
surge absorber, or telephone earth. Incomplete earth may cause 
electrical shock,

Q

be sure to install an earth leakage detector in accordance with the 
applicable legislation. Failure to do so may cause electric shock 
or fire. The earth leakage detector is a field supplied part,

Q

be sure to install the required fuses or circuit breakers. The fuse 
or circuit breakers are field supplied parts.

Electrical characteristics

Table 3.2: Electrical characteristics

(a)

 In case of common power supply to more than one unit (as illustrated in figure 13: “Group 

control or use with 2 remote controllers”), keep total current of interconnection wiring 

between units less than 12 A. Branch the line outside the terminal block of the unit in 

accordance with electrical equipment standards, when using two power wires of a gauge 

greater than 2 mm². The branch must be sheathed in order to provide an equal or greater 

degree of insulation as power supply wiring itself.

Specifications for field wiring

Table 3.3: Field wiring specifications

(a)

 Only in case of protected pipes. Use H07RN-F in case of no protection.

(b)

 Run electrical wiring through a conduit to protect against external forces.

(c)

 Use double insulation wire for remote controller (sheath thickness: 

1 mm) or run wires 

through a wall or conduit so that the user cannot come in contact with them.

(d)

 This length is the total extended length in the system in case of group control. See figure 

13: “Group control or use with 2 remote controllers”.

Prepare the installation of the fan coil unit

3.6.

Prepare the installation of optional 

equipment

Air flow directions

For this unit you can select different air flow directions. It is necessary 
to purchase an optional blocking pad kit to limit the air discharge to 2, 
3 or 4 (closed corners) directions. 
Select the air flow directions best suited for the room and point of 
installation. For air discharge in 2 or 3 directions, it is necessary to 
make field settings by means of the remote controller and to close the 
air outlet(s) as illustrated in figure 1: “Airflow directions”. (

Unpack the unit

When receiving the unit, please check its state. Verify if any damage 
occurred during transport. If the unit and/or packing are damaged at 
delivery, report this immediately to the carrier’s claims agent. 
Identify model and version of the unit from the indications stated on 
the carton packing. 
Leave the unit inside its packing until you reach the installation site. 
Where unpacking is unavoidable, use a sling of soft material or 
protective plates together with a rope when lifting, this to avoid 
damage or scratches to the unit. 

When unpacking the unit or when moving the unit after unpacking, be 
sure to lift the unit by holding on to the hanger bracket without exerting 
any pressure on other parts. 

Warning

A main switch or other means for disconnection, having a 
contact separation in all poles, must be incorporated in the 
fixed wiring in accordance with the applicable legislation.

Information

The equipment described in this manual may cause 
electronic noise generated from radio-frequency energy. 
The equipment complies to specifications that are designed 
to provide reasonable protection against such interference. 
However, there is no guarantee that interference will not 
occur in a particular installation.
It is therefore recommended to install the equipment and 
electric wires keeping proper distances away from stereo 
equipment, personal computers, etc.
In extreme circumstances a distance of 3 m or more is 
required.
