3.0 HYDRAULIC CONNECTIONS
Connect the heat exchanger using a 1/2” GF attachment to the water
supply, using a spanner and counter-spanner to avoid damage to
the battery connections. The pipes can come from the floor, wall or
ceiling. To bleed any air in the circuit, use a fiat screwdriver to open the
valve on the top at the side of the attachments. If the fan-coil heater is
also used for air conditioning, connect the condensation outlet to the
collection circuit; if the additional external tray has not been requested,
the cooling water pipes must be insulated against condensation. It is
advisable to make a water trap on the condensation outlet pipe to avoid
intake of evil-smelling air. When the connections are terminated, check
there are no water leaks from the exchanger or tray. The exchangers
are supplied to work with a maximum pressure of 10 bar. The battery
attachments on the tandard unit are on the left but if needed they can be
moved to the tight (refer to the inverting battery attachments chapter). To
instali the valves on the two or four pipe versions, follow the instruetions
given in the technical manual or included in the valve kit.
- IN COOLING FUNCTION (TO AVOID WATER CONDENSING) WE
SUGGEST EV2, EV4.
4.0 ELECTRIC CONNECTIONS
Turn the power of at the mains before beginning the electric connections.
The connections must be made in conformity with current standards in
force following the enclosed wiring diagram with each fan-coil heater. Ali
the fan-coil heaters are supplied with a connection box (standard fitting on
the right), which contains ali the regulation components and the grounding
terminal. To reach the components, unscrew the two screws in the cover
next to the lead outlets. Each fan-coil heater must be power ed with single
phase 230 volts (tolerance of-51+10) 50 Hzfrequency. A bipolar motor-ci
cuit switch must be installed upstream from the fan-coil heater.
