General warnings
• This water heater is fitted with a thermostat with an operating temperature of more
than 60°C at its maximum position, capable of reducing growth of legionella bacteria in
the tank.
Caution! Above 50°C, water could cause immediate scalds. Check the water temperature
before taking a bath or shower.
HYDRAULIC CONNECTION
• A new safety device which conforms to current standards (in Europe EN 1487),
pressure 0.8MPa (8 bar) and size 1/2" in diameter must be fitted. The safety valve must
be protected from frost.
• A pressure reducer (not supplied) is required when the water supply pressure exceeds
0,5MPa (5 bar).
• Your pipes must be rigid (copper) or fl exible (stainless steel woven hoses) and be able
to withstand 100 °C and 1 MPa (10 bar). Otherwise, a temperature limiter must be used.
• Connect the safety device to an unpressurised outlet pipe in a frost free environment,
with a continuous slope for the evacuation of the water during heating up or draining
the water heater.
• Operate once a month the discharge of the safety device to prevent scaling and verify
that it is not blocked.
• To drain the appliance : Turn off the power and the supply of cold water, open the
hot water faucets and manipulate the safety valve before performing these operations.
• Check that the water heater is fi lled correctly before it is powered on; when a HOT
WATER tap is turned on, COLD WATER should flow out.
• A small amount of smoke may be emitted when heating starts; this is completely
normal
