IMPORTANT NOTE: BRUSHLESS MOTOR
The electrical connection for CIAT Comfort Units must be made in compliance with
international standard IEC 60364 (Electrical Installations for Buildings).
The leakage current for all our Comfort Units complies with the requirements of standard IEC
60335-2-40 (Household and similar electrical appliances - Safety):
- Complete comfort unit (with electrical heaters) equipped with a multi-speed motor: maximum
leakage current = 2mA
- Complete comfort unit (with electrical heaters) equipped with an HEE motor (Brushless
technology): maximum leakage current = 4.5mA
CONDENSATE DRAIN PAN
The MAJOR LINE is equipped with a sloping polymer pan which does not retain water, fitted
with a Ø22mm external drain end piece and a plug.
When the unit is delivered, the pan is blocked on both sides (2 plugs), so it is therefore
imperative that the plug is removed from the side where the hydraulic connection is to be made.
If the hydraulic connection side is switched, do not forget to refit
the plug to the side not used.
The connection can be made on the left or right-hand side of the unit.
The drain hose can be separate for each unit or corrected to a main drain hose. Use a clear
and/or rigid drain hose for a minimum slope of 1 cm/m, with a constant level along its whole
length. Install a trap measuring at least 5 cm to prevent unpleasant gases or odours
exiting the hose.
An auxiliary pan must be installed on the connection side using the 2 screws (fig. 11, a).
CONDENSATE DRAIN PUMP
The MAJOR LINE can be equipped with a condensate drain pump.
Its technical specifications are as follows:
●
Maximum flow of 7l/hr for a drain height of 1 metre and a maximum pipe length
of 5 metres.
●
Maximum flow of 6l/hr for a drain height of 1 metre and a maximum pipe length
of 10 metres.

Important: check that the flow rate of the water to be evacuated in thermal selection corresponds to
your particular case
