Page 4: About Your Water Heater
The Rheem Water Star water heater you have chosen can be installed indoor or outdoor. The Water Star has been designed to be installed with a continuous flow gas water heater. Where the water heater is installed with a continuous flow gas water heater and a hot tap is turned on, the Water Star commences to deliver hot water immediately from its outlet. - Page 5 We recommend and it may also be required by regulations that an approved temperature limiting device be fitted into the hot water pipe work to the bathroom and ensuite when a Water Star 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 still allow hotter water to the kitchen and laundry.
- Page 6 The thermostat is fully automatic and power is only used when heating is required. The thermostat on a Water Star has a fixed setting at 70°C. This cannot be adjusted. TO TURN OFF THE WATER HEATER If you plan to be away from home for only a few nights, we suggest you leave the water heater switched on.
- Page 7 Open the cold water isolation valve fully on the cold water line to the water heater. If not already connected to the Water Star or to another power outlet, plug in the power supply cord of the continuous flow water heater at the electrical socket on the underside of the Water Star.

13. WATER TEMPERATURE TOO HIGH A Water Star has a fixed thermostat setting of 70°C. When a hot tap is turned on, hot water delivered from the Water Star will be up to this temperature. The water temperature will decrease to the outlet temperature setting of the continuous flow water heater when the hot water from the continuous flow water heater reaches the tap. - Page 13 Heavy flows of hot water until water heater is cold - then stops until water reheats The water heater must be switched off at the isolating switch.
