Hydraulic connections

on open system (e.g. when using well water), the wa-
ter used should be cleaned from suspended matter
by means of a filter which should be located in the
inlet. otherwise there is a risk of erosion due to sus-
pended matter.
You must also ensure that the unit is protected from
dust and other substances that cause an acid or al-
kali reaction when combined with water (aluminum
corrosion).
If the unit is equipped with a valve, connect the con-
nection pipes to the valve.
Maximum working pressure: 10 bar.
Always use two spanners to connect the coil
to the pipes.
2.11
Always fit a gate valve in the water circuit.
Please make sure that no leakage occurred.
To avoid leakage please insulate the threated ends
of the tubes with hamp and tighten them with care.
If the unit is used for cooling, insulate the pipes and
valve to avoid drops of condensate forming.
during the summer and when the fan is inactive for
long periods, you are recommended to shut off the
water supply to the coil to avoid condensation form-
ing on the outside of the unit.
Connect the siphon to the drain according to the
figure.

2.12
Install a condensate drain pipe with a slope of
at least 3 cm/metre.
Pour a few litres of water into the condensate collec-
tion tray to make sure it is properly evacuated. In case
of problems, check the sizing of the siphon, slopes or
possible obstructions.
Valves

tor can be found at p. 26.

General warnings

Perform electrical connections in accordance
with laws and regulations in force in the country
concerned.
The wiring diagrams do not address protective
grounding or other electrical protection which will
be required under local rules, regulations, codes and
standards or by the local electricity supplier.
Before installing the fan coil, check that the nominal
supply voltage is 230-240 V / 50-60 Hz.
The power supply is always connected to terminals L,
N and PE on the board.
The maximum power consumption for operation at
230-240 V AC is shown in the table below:
