Start-up
● Open the hot water valve(s).
● Open the cold water valve on the safety
unit (make sure that the heater drain valve
is in the closed position).
● After water starts to flow through the hot
water taps, close them and you water hea-
ter is full of water.
● Check that tubing connections are not
leaking, and check the door seal under the
electrical cover. Retighten it if necessary.
● Check that water control devices are wor-
king correctly by turning the safety valve
from the drain position to the off position
and vice versa, in order to eliminate any
waste.
IMPORTANT
A direct connection to the elements (without passing through the thermostat) is
prohibited in all circumstances because it is dangerous, since there is no control
over the water temperature anymore.
■ FILL THE WATER HEATER
■ CHECKING CORRECT OPERATION
● Switch the heater on.
● Put the switch on the electrical panel into
the forced operation position. After 15 to
30 minutes, water should start dripping
through the safety unit drain outlet (which
must be connected to a waste water drain
pipe).
This phenomenon is normal; it is due to
expansion of water due to heating.
Consequently, the safety valve will allow a
certain amount of water to escape so that
internal pressure in the tank does not
exceed 7 bars. This flow may be about 2 to
3% of the capacity of the tank when it
warms up from cold.
Check the tightness of the connections and
the door seal once again.
If the check result is positive and if your
electrical panel is equipped with an Off-
peak hours (low night rate) servocontrol
relay, put the switch to the "automatic" posi-
tion.
You will see 3 positions in this switch :
- Off or "0" position
- Automatic or "AUTO" position
- Forced operation or "1" position.
After switching on the water heater check the indicator light on the casing.
- When operating normally, it should be permanently lit (24 hours a day):
- Orange: heating + ACI protection
- Green: ACI protection only
NOTE
The water heater can make a slight noise like a boiler while heating, depending on the water
quality. This noise is normal and does not mean that anything is wrong with your heater.
■ RECOMMENDATIONS
● Provide sufficiently long cables to avoid
contact with heating elements.
● A direct connection onto a power outlet
is prohibited, since the water heater is not
equipped with a cable clamp.
● An earthing connection is compulsory for
safety reasons.
● Before making the final connection for
the heater, make sure that it is full of water.
If not, it is impossible to supply electrical
power to the water heater (Dry heating
protection).
