2.0. Instructions Before Start-up
This appliance is designed to heat water below boiling temperature at
atmospheric pressure. It shall be connected to a domestic water system
suitable for its performance and output power. The appliance shall be
attached to a wall that is strong and in a stable condition so that the faste-
ners can support the weight of the appliance. The connection base and
hanger holes shall be marked precisely using the installation template
supplied with the appliance. Always check that the appliance is level.
The appliance shall be grounded as per TSE standards. NYAF cable with a
cross section of 3x0.75 mm2 approved by TSE shall be used for the elect-
rical connection.
(Always have your electrician install a 2 ampere fuse.)
The cold water inlet shall not exceed the operating pressure (8 bar)
specified on the rating plate of the appliance. If the mains pressure is
higher than 6.5 bar, always install a pressure reducer. No danger of
freezing shall be present in the environment where the appliance is
installed.
Ball valves shall be connected to the cold water inlet (1/2"), hot water
outlet (1/2") and gas inlet (3/4") of the appliance. A filter shall be installed
before the cold water inlet A.
The appliance shall be connected to a 220-230 V single-phase, grounded
power supply.
Your appliance has been designed to perform its normal functions between
a minimum of 195 V and a maximum of 253 V in line with the standards.
We recommend you to use a voltage regulator if the power network to
which the appliance shall be connected cannot provide this range
(195-253 V).
Protect your appliance from external physical and chemical effects.
Carry out the handling and transportation operations with the original
packaging of the appliance, taking into account the markings on the
packaging of the appliance. Protect your appliance from factors that can
damage the packaging and the appliance itself (moisture, water, impact,

by the gas installation available. Check the labels on the packaging and the
appliance.
You shall not intervene with the components and elements that are sealed
on the appliance.
