Casing removal
Remove the screws that keep the casing fastened.
2.11
Remove the casing from the structure.
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.
The installer must always test the tightness of the
valve kit connections, also when it is provided fitted
on the unit.
In case of coil water leakage during the pressuriza-
tion of the installation, it is mandatory to isolate hy-
draulically the unit and contact the Sabiana Assis-
tance Service.
Coil maximum working pressure: 16 bars.
Always use two spanners to connect the coil
to the pipes.
2.12
Always fit a lockshield 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.
2.13
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.
