4.4 DRAIN PIPE
For condense draining (2 locations), prepare a polyvinyl chloride
pipe with a Ø25mm. OD (outer diameter).
Fasten the field supplied pipe to the Drain Hose with adhesive.
The drain piping should be performed with a down-slope pitch of
1/25 to 1/100.
Connect a syphon, as shown at the figure below.

It is very important the syphon installation in order to guarantee
the proper condensate draining.

5.1 GENERAL CHECK
• Make sure that the following conditions related to power sup-
ply installation are satisfied:
-
The power capacity of the electrical installation is large
enough to support the power demand of the indoor unit.
-
The power supply voltage is within ±10% of the rated volt-
age.
-
The impedance of the power supply line is low enough
to avoid any voltage drop of more than 15% of the rated
voltage.
• Following the Council Directive 2004/108/EC, relating to elec-
tromagnetic compatibility, the table below indicates the Maxi-
mum permitted system impedance Z
max
at the interface point
of the user’s supply, in accordance with EN61000-3-11.

• Check to ensure that existing installation (mains power switch-
es, circuit breakers, wires, connectors and wire terminals) al-
ready complies with the national and local regulations.
