• Select power level using switches on front of unit. The two
switches give 4 levels (including off). in Uk conditions the
unit should normally be switched to full power.
• Switch on electrical supply.
• Turn on tap. when the flow rate exceeds about 1.2 litres
per minute the unit will start to heat the water.
• as the flow rate is increased the temperature will start
to fall.
• if the flow rate is gradually reduced the temperature will
rise gain. if the temperature exceeds approximately
60 degrees the unit will switch off to prevent scalding.
it will restart again when the unit has cooled provided the
flow is maintained.
