OPERATING INSTRUCTIONS

Your new Instant Water Heater is flow-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 flow of water through the appliance. You will need to allow at least 2.1 liters per minute to flow through the unit in order to activate the Instant Heating System. Run water through the heater for a few minutes.
Be sure to every so often clean the spray head to assure a smooth water flow.
Be sure to every so often clean the incoming water filter.
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.
The user can adjust the hot water temperature regulating the setting power on the unit. the user can choose from 4 different power settings:
– O – The heating element is off
– 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.

Troubleshooting

SYMPTOM	POSSIBLE CAUSE	SOLUTION
The water is not hot enough	Too much water flowing through the heater

Reduction In the ambient temperature
Water Pressure below 100 kPa
Electrical Malfunction| Reduce the flow rate of the water via the outlet tap.
Switch to a higher temperature setting.
Check if the mains stop valve is fully open and that there are no other restrictions in the supply line.
Have the Heater unit checked by a qualified electrician or contact your local authorized distributor.
Water too hot| Not enough water flowing through the heater
Increase in the ambient temperature| Increase the flow rate via the outlet tap Switch to the lower temperature setting
The heater switched Off during use| Interruption of mains electrical supply
ELSD trip, possible earth leakage| Check incoming power supply, MCB, switches, and supply cabling. Check earth leakage and reset ELSD
If the problem persists, call your local authorized distributor for assistance.
Water ceases to flow| Blockage of spray head twisted or blocked flexible shower hose.
No water supply.| Clean or replace the spray head, and check for free passage of water through a hose. Replace as necessary.
Check water supply, stop valve Open? and no blockage.
Water temperature varies from hot to cold during use| Water pressure has dropped below min. level.| Increase hot water supply,
No hot water despite a fully open hot water outlet| No electrical power
The activation flow rate needed to turn on the heating element has not been reached.| Check the circuit breaker and check the voltage at the wiring block.
Clean filter screen
•Turn the circuit breaker off
•Open the hot valve to release pressure from the unit.
•Turn circuit breaker on.
