● 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 heater is
full of water.
● Check that tubing connections are not lea-
king, and check the door seal under the electri-
cal cover. Retighten it if necessary.
● Check that water control devices are working
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 anymo-
re.
■ 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 minu-
tes, water should start dripping through the
safety unit drain outlet (which must be connec-
ted to a waste water drain pipe).
This phenomenon is normal; it is due to expan-
sion 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 t a n k
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 electri-
cal panel is equipped with an Off-peak hours
(low night rate) servocontrol relay, put the
switch to the "automatic" position.
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 equip-
ped 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).
