• If the appliance is set up in a suspended ceiling or attic, or above
living space, a drain pan must be installed underneath the water
heater. A drainage device connected to the sewer system is required.
• This product is intended for use at a maximum altitude of 2000 m.
• This water heater is fitted with a thermostat with an operating
temperature of more than 60 °C at its maximum position, capable of
reducing the growth of legionella bacteria in the tank.
Caution! Above 50 °C, water could cause immediate burns. Check
the water temperature before taking a bath or shower.
HYDRAULIC CONNECTION
• A new safety device which conforms to current standards (EN 1487
in Europe), pressure 0.8 MPa (8 bar) and size 1/2" in diameter must
be tted. The safety valve must be protected from frost.
• The pressure relief valve drainage device must be activated on a
regular basis in order to remove limescale deposits and to check that
it is not blocked.
• A pressure reducer (not supplied) is required if the supply pressure
is greater than 0.5 MPa (5 bar) and will be installed on the main
supply pipe.
• Connect the safety unit to a discharge pipe, kept in the open air, in
a frost-free environment, continuously sloping downwards to drain off
the heat-expanded water or to allow for drainage of the water heater.
• The working pressure of the heat exchanger circuit must not
exceed 0.3 MPa (3 bar), its temperature must not exceed 100 °C.
• DRAIN: Turn o the power and cold water supply, open the hot
water taps then operate the drainage valve of the safety device.
• NOTE: For water heaters under sinks, disconnect the hydraulic unit
and turn it upside down to drain.
