CAUTION!
Always use a wrench and counter-wrench for connection of the coil to the pipes (fig. 13). If the solenoid valve
is installed, suitably insulate the valve body with insulating material (fig. 14).
Connect the water inlet and outlet pipes, observing the indications given on the side of the unit. Correctly insulate the
water supply pipes to prevent dripping during the cooling mode of operation. A 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.

WATER CONNECTIONS
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 rising 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 pouring water into the tray. 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.
