INSTALLATION
OPERATING INSTRUCTIONS
1. Your new Instant Water Heater is ow activated. Regulate the knob in one of the 3 setting power (I, II,
III) the product will switch ON once the hot water tap is turned on, the heating element will work and
warm the water only when there is a ow of water through the appliance.. You will need to allow at least
2.1 litres per minute to ow through the unit in order to activate the Instant Heating System. Run water
through the heater for a few minutes.
2. Be sure to every so often clean the spray head to assure a smooth water ow.
3. Be sure to every so often clean the incoming water lter.
4. Be sure to install your Instant Water Heater in a heated location. The appliance cannot be installed in
areas where the temperature may drop critically and there may be a risk that ice may form.
5. The user can adjust the hot water temperature regulating the setting power on the unit. the user can
choose from 4 dierent power settings:
- O - Heating element is o
- I - Only the 1st Heating element switches on.
- II - Only the 2nd heating element switches on.
- III - 1st and 2nd heating elements switch on, working together.
INSTALLATION REQUIREMENTS
A. A separate electrical supply is required.
B. The device must be connected to a separate circuit breaker.
C. The recommended electrical cable for supplying the device, see table I (next page)

Troubleshooting
SYMPTOM POSSIBLE CAUSE SOLUTION
Water not hot
enough
Too much water owing through
the heater
Reduction In the ambient
temperature
Water Pressure below of 100 kPa
Electrical Malfunction
Reduce the ow rate of the water via the
outlet tap.
Switch to higher temperature setting.
Check if the mains stop valve is fully open
and that the there are no other restriction
in the supply line.
Have the Heater unit checked by a
qualied eIectrician or contact your local
authorised distributor.
