Commissioning the water heater
1. Filling the water heater
1. Open the hot water valve(s).
2. Open the cold water valve on the safety unit (make sure that the heater drain valve is in the closed position).
3. Once the water flows steadily from the hot water taps, close them. The water heater is full.
4. Check that tubing connections are not leaking, and check the door seal under the electrical cover. Retighten
it if necessary.
5. Check that tubing connections aure not leaking, and check the door seal under the electrical cover. Retighten
it if necessary.
2. Checking that the appliance works
1. Switch on the power.
2. If your electric board is fitted with a relay to take advantage of off-peak rates (reduced prices at night), set the
switch to
permanently on (I)
. You will see 3 positions in this switch.
• Off or
0
position
• Automatic or
Auto
position
• Forced operation or
1
position
3. After 15 to 30 minutes, 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 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 –
0,7 MPa. This flow may be about 2 to 3% of the capacity of the tank when it warms up from cold.
4. Check the tightness of the connections and the door seal once again.
For water heaters Steatite Magnesium:
u
When first powered up, smoke and odour may be released from the heating element. This is normal and
disappears after a few minutes.
u
While heating up, depending on the quality of the water, the water heater may make a quiet noise like a kettle.
This noise is normal and does not mean there is anything wrong with the appliance.
