Overview
A poor duct installation (duct compressed, length or number of bends too high...) can reduce the
performance. Thus the use of flexible ducts is not recommended.

In case of installation without ducts, it is possible to change the
position of the grids in order to guide the air flow. In order to do
this, it is necessary to unscrew the grids and to re-screw it on one of
the two allowed positions. It is forbidden to place both grids
towards each other.
8. Electric connection
Refer to the electric connections diagram below and on last page.
The water heater must not be switched on before complete filling with water.
The water heater must be connected to electricity supply permanently.
The water heater has to be connected on single phase 230 V alternative current. Connect the water heater
with a cable with rigid conductors with section of 1,5 mm². The installation is composed of :
• A 16A omni-polar circuit breaker with contacts opening at minimum 3mm,
• A 30mA differential circuit breaker.
If the power cable is damaged, the manufacturer, the after-sales service or similarly qualified people must
replace it, to avoid danger.
Never supply power directly to the heating element.
The security thermostat fitted to the auxiliary electric heating element must not be repaired in other places
as our factory. Failure to respect this clause invalidates the warranty.
The device must be installed in accordance with the national electrical installation rules.
