4.7 Using the appliance
A D B
C
- Make sure that the gas valve and all water taps are shut off.
- Turn on the gas meter/LPG cylinder valve.
- Turn on the valve immediately before the appliance on the gas inlet pipe.
- Ensure that the appliance is receiving power (check the phase, neutral
and earth wires).
- When the appliance is powered the green LED
(fig. 21 -
C
)
flashes on
for 1 second and remains off for 5 seconds; turn the dial
(fig. 21 -
A
) to
the “ ”
position: the green LED will flash with equal frequency. Turning on
the hot water dispensing tap starts the circuit board ignition sequence
once a flame has been detected; the green LED (fig. 21 -
C
) will switch
from flashing to remaining on
. When the tap is shut off, the appliance will
switch to stand-by mode and the green LED
(fig. 21 -
C
)
will flash to show
that the appliance is ready for further withdrawals.
- Should the burner not ignite within 10 seconds, the red LED
(fig. 21 -
D
)
will illuminate. To resume operation, turn the dial
(fig. 21 -
A
) manually to
the “ ” position and then the “ ” position.
b
Should the warning light continue to come on, please seek assis-
tance from a specialist technician at our Technical Support Centre.
b
Should the main burner accidently be switched off during normal op-
eration, try turning on once again.
b
If the appliance does not begin operating again within 10 seconds,
the red LED
(fig. 21 -
D
) will light up.
- Should the electricity supply be interrupted accidentally, the solenoid
valves will intercept the gas flow; when power is restored, the ignition
sequence is repeated.
- The air pressure switch monitors correct evacuation of the products of
combustion and intake of the combustion air.
In case of anomalies in the inlet and outlet pipes, the pressure switch stops
the flow of gas to the main burner. Once the anomaly has been rectified, the
appliance resumes normal operation.
USING THE WATER TEMPERATURE CONTROL POTENTIOMETER
Turn the dial
(fig. 21 -
B
) to select the hot water temperature requested.
The requested temperature can be provided with a tolerance of ±2°C with
respect to the value shown in the graph.
WATER OVER-TEMPERATURE CONTROL DEVICE
The appliance is fitted with a device which monitors the temperature of
the water as it leaves the heat exchanger. The device consists of a safety
thermostat which interrupts appliance operation by intercepting the flow of
gas to the main burner when the water flowing into it exceeds a preset
temperature.
Should the device be activated, the appliance will not work. The red warning
light
(fig. 21 -
D
)
will flash at intervals of 0.5 seconds
.
To resume operation, turn the dial
(fig. 21 -
A
) manually to the “ ” position
and then the “ ” position.
Should the device be activated frequently, please seek assistance from a
qualified professional at our Technical Support Centre.
If there is a chance that the temperature in the area where the appliance is
installed may fall below zero, drain the water from the appliance.
To do so, shut off the cold water supply tap and turn on the user hot and
cold water taps.
