CAUTION!

Always use a wrench and nose key for connection of the coil to the pipes (fig. 29). If the solenoid valve is installed, suitably insulate the valve body with insulating material (fig. 30).

Connect the water inlet and outlet pipes, observing the indications given on the side of the appliance. Correctly insulate the water supply pipes to prevent dripping during the cooling mode of operation. An shutoff valve should be inserted on the water supply pipe and a balancing valve on the outlet pipe. The valve body and balancing valve should also be properly insulated to prevent dripping. It is the installer's responsibility to insulate properly and the manufacturer cannot be held liable for any insulation work.

N.B.: It is always advisable to install the solenoid valve. In the heating mode of operation the solenoid valve reduces consumption because upon reaching the set temperature the circulation of water is stopped to avoid wasting energy (the fan coil would otherwise continue to heat like a radiator, even with the motor at a standstill). In the cooling mode of operation the solenoid valve stops the circulation of water when the set temperature is reached, thus stopping the internal exchanger from continuing to condense water with possible undesirable dripping onto the floor. It also reduces chiller operation with consequent energy saving.

CONNECTION TO THE WATER MAINS

CONDENSATE WATER DRAINAGE

The condensate drain pipe should slope downwards by at least 3 cm/m and should not have ascending or throttled sections in order to ensure a regular flow of water. It is advisable for a trap to be fitted. The condensate drain pipe should be connected to a rainwater drainage system. Do not use sewage systems to avoid possible odours in the event of evaporation of the water in the trap. Upon completion of work, check that the condensate flows out properly by pouring water into the tray (see figs. 31 and 32). The condensate water drainage system should be fabricated in a workmanlike manner and should be periodically checked.

The manufacturer cannot be held liable for any damage caused by dripping in the absence of a solenoid valve or of periodic maintenance of the drainage system.

The cables should be sufficiently long so that they are not permanently taut or create throttling or pressure on metal parts (see fig. 33).

The power cables should be sufficiently long so that in the event of accidental tugging the active wires are subjected to stress before the earth wire. Connect the earth wire to the relative terminal marked with the symbol

Check the earth connection.

Comply with the safety regulations in force in the country of installation.

ELECTRICAL CONNECTIONS

RECOMMENDATIONS

Before carrying out electrical connections, ensure that the electricity supply to the supply line has been cut off, checking that the on-off switch is in the OFF position. Only qualified electricians should carry out the electrical connections. Check that the mains supply is single-phase 230 Vac/1/50 Hz (± 10%). Operating the appliance with voltages outside the above limits could cause malfunction and renders the warranty null and void. The fan coil power supply line should be fitted with at least a switch isolator in conformity with European standard EN60947-3. Make sure that the electrical system is suitable for providing not only the working current required by the appliance, but also the necessary current for powering household and other electrical appliances already in use. Any electrical and mechanical alterations or tampering render the warranty null and void. The motor and accessories power cables in channels or ducts should remain inside the same until they are inside the appliances.

CONNECTIONS TO THE TERMINAL BLOCKS

Models without control panel

The electrical connections should be made to the terminal block on the side of the appliance. Each terminal is identified by the label to be found on the terminal block.

Page 13

Models with control panel

The electrical connections should be made directly to the control panel, as shown by the relative wiring diagram. If the control panel has an electronic temperature sensor (NTC), this sensor will be powered by mains voltage (230Vac/1/50 Hz) and is therefore provided with double insulation.

CAUTION! FAILURE TO COMPLY WITH THE INDICATED CONNECTIONS MAY CAUSE

MOTOR BURNOUT!

CHANGING THE MOTOR SPEEDS OF ROTATION

The fan coil motor has 6 speed settings, 3 of which are connected in the factory (red, blue and black wires connected to the motor auto-transformer). To use other speeds than those wired up in the factory, the red (minimum), blue (medium) and black (maximum) wires may be connected onto 3 of the 6 numbered terminals (16), taking into account

that the speeds follow a sequence as shown in fig. 35.

* CAUTION! UNDER NO CIRCUMSTANCES SHOULD THE CONNECTIONS TO THE TERMINALS L, M, M BE CHANGED!

TESTING THE FAN COIL

Upon completion of installation, scrupulously check both the water and the electrical connections before switching on the appliance. Before mounting the housing (if present), fill the system, bring it up to pressure and bleed. Make the water circulate and check for leaks. Check correct operation of the fan

coil at the 3 speeds, of the solenoid valves and of the minimum temperature thermostat (if installed). The housing is covered by a protective film: remove it before fixing the housing to the appliance.

Remount the housing (if present), otherwise the customer has the responsibility of concealing the appliance.

CAUTION! Protect the appliance with a cardboard box if building works are still being carried out (Fig.

36).

USING THE APPLIANCE WITH CONTROL PANEL

If the appliance has a built-in control panel, raise the flap and proceed as follows.

Heating mode

Put the season selector switch from the off position ( ) to the winter position ( ). The fan starts. In models with minimum temperature thermostat (optional), the fan starts when the internal heat exchanger is sufficiently hot. If the water is not hot enough, the fan does not start.

Cooling mode

Put the season selector switch from the off position ( ) to the summer position ( ). The fan starts immediately.

Selecting the fan speed

Put the selector switch to the required speed. The higher the speed the quicker the room will be heated/cooled, although appliance operation will be noisier (fig. 40).

Automatic temperature adjustment (for control panel with built-in thermostat) This control panel has a built-in temperature sensor, which measures the room air temperature. This information is used for the automatic control of the fan or introduction of water into the internal exchanger through the solenoid valve (optional). The appliance thus keeps the room at the temperature set by the user.
