OPERATION
WATER FLOW AND TEMPERATURE ADJUSTMENT
Water fixtures with a rated water flow rate of 7.5 litres per minute or higher are recommended.
A water flow adjustment lever is fitted to adjust the maximum water flow from the appliance. Such adjustment may
be useful to compensate for seasonal variations in the temperature of the cold water supply.
•
Turning the water flow adjustment lever towards the left (Clockwise) will decrease the water flow and
increase the hot water temperature. This setting is recommended during winter.
•
Turning the water flow adjustment lever towards the right (Anti-clockwise) will increase the water flow and
decrease the hot water temperature. This setting is recommended during summer.
•
If the heated water temperature delivered from an outlet is not hot enough it can normally be increased to
the desired temperature by closing the tap a little as this will reduce the water flow rate.
•
The appliance has a minimum water flow rate that is required for operation. If the water heater does not
activate when opening a tap, the flow rate may be too low. Open the tap a little more to increase the water
flow rate.
FREEZING WEATHER
This water heater MUST NOT be installed in areas where the temperature remains below 0°C for
extended periods.
WARNING
If freezing conditions are expected (drop below 0°C), turn off water and gas and drain all water from the appliance
to prevent damage by expansion of freezing water.
For appliances installed in locations where the temperature falls below 0°C for short periods, the installation of an
Anti Freezing Relief Valve (Exogel or equivalent brand) will minimise the possibility of damage to the appliance.
This is not supplied with the water heater.
