Page 4: About Your Water Heater
Solar heated water can reach temperatures up to 75°C for an Everhot solar direct or indirect pumped system and possibly higher for some other models of solar water heaters. The in-series gas booster operates automatically. - Page 5 We recommend and it may be required by regulations that an approved temperature limiting device be fitted into the hot water piping to the bathroom and ensuite when a 271 series water heater is installed. This will keep the water temperature below 50°C at the bathroom and ensuite. The risk of scald injury will be reduced and if no controllers are installed and the preset outlet temperature setting has not been adjusted below 55°C or if a Kitchen controller is installed, still allow hotter water to the kitchen and laundry.
- Page 6 Warning: For continued safety of this water heater it must be installed, operated and maintained in accordance with the Owner’s Guide and Installation Instructions. The Everhot warranty may not cover faults if relief valves or other safety devices are tampered with or if the installation is not in accordance with these instructions.
- Page 7 ABOUT YOUR WATER HEATER PRECAUTIONS Where damage to property can occur in the event of the water heater leaking, the water heater must be installed over a safe tray.

In a corrosive water supply, the water can attack copper parts and cause them to fail. Where the saturation index is less than –1.0, the water is very corrosive and the Everhot warranty does not apply to a copper heat exchanger in a continuous flow water heater. -
Page 23: Save A Service Call
Check the items below before making a service call. You will be charged for attending to any condition or fault, which is not related to manufacture or failure of a part (refer to “Terms of the Everhot Warranty” page 55). - Page 24 • Collector area is too small For most installations, the number of solar collectors recommended in Everhot literature has been proven to provide the required solar energy to meet the average family needs. However, in some circumstances, it may be necessary to install an additional solar collector.
