!
CAUTION! If the valve is installed, suitably insulate the valve body with insulating
material (fig. 1 ).
Connect the water inlet and outlet pipes, observin the indications iven on the side of
the unit. Correctly insulate the water supply pipes to prevent drippin durin the coolin
mode of operation. A shutoff valve should be inserted on the water supply pipe and a
balancin valve on the outlet pipe. The valve body and balancin valve should also be
properly insulated to prevent drippin . 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 valve.
In the heatin mode of operation
the valve reduces consumption because upon reachin the set temperature the
circulation of water is stopped to avoid wastin ener y (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 valve stops the circulation of water when the set
temperature is reached, this 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.
!
CAUTION! Always use a wrench and counter-wrench for connection
of the coil to the pipes (fig. 11).
Fig. 1
Fig. 13
3 cm/m
The condensate drain pipe should slope downwards by at least 3 cm/m and
should not have ascendin or throttled sections in order to ensure a re ular flow
of water. It is advisable for a trap to be fitted. The condensate drain pipe should
be connected to a rainwater draina e system. Do not use sewa e systems to
avoid possible risin of odours in the event of evaporation of the water in the trap.
Upon completion of work, check that the condensate flows out properly by
pourin water into the tray. The condensate water draina e 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 valve or of periodic maintenance of the drainage system.
ELECTRICAL CONNECTIONS
!
RECOMMENDATIONS
Before carryin out electrical connections, ensure that the electricity supply to the
supply line has been cut off, checkin 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 sin le-phase 230 Vac/1/50 Hz (± 10%).
- Operatin the unit with volta es outside the above limits could cause malfunction
and renders the warranty null and void.
- The 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 providin not only the workin
current required by the unit, but also the necessary current for powerin household
and other electrical appliances already in use. Any electrical and mechanical
alterations or tamperin render the warranty null and void.
The cables should be sufficiently long so that they are not permanently
taut or create throttling or compression on metal parts.
The power cables should be sufficiently lon so that in the event of accidental
tu in the active wires are subjected to stress before the earth wire. Connect
the earth wire to the relative terminal marked with the symbol . Comply with
the safety re ulations in force in the country of installation.
CONNECTIONS TO THE TERMINAL BOARDS
The electrical connections should be made to the terminal boards on the side
of the appliance. Each terminal is identified by the label to be found on the terminal
boards.
