Operating Instructions
* Damage can occur from frozen water within the device and pipes even in warm environments.
Be sure to read below for appropriate measures.
* Repairs for damage caused by freezing are not covered by the warranty.
Freezing cannot be prevented when the power plug is unplugged. Do not remove the power
plug from the wall outlet.
(Freezing will be prevented regardless of whether the operation switch is ON or OFF.)
* The freeze prevention heaters will not prevent the plumbing external to the unit from freezing.
Protect this plumbing with insulation, heat tape or electric heaters, solenoids, or pipe covers.

water piping and mixing valves.
1. Turn the unit off with the Operation Button on the Remote Controller.
2. Close the gas supply valve.
3. Open a hot water fixture, and keep a small amount of hot water running
(400cc / minute or about 4mm thick).
* If there is a mixing valve, set it to the highest level.
4. The flow may become unstable from time to time. Check the flow 30 minutes later.
If water will not flow because it is frozen
1. Close the gas and water valves.
2. Turn off the operation button.
3. Open the water supply valve from time to time to check whether water is running.
4. When the water is flowing again, check for water leaks from the equipment and piping before using.
If the heater or the piping is frozen, do not use the heater or it may get damaged.

* In general, it is not advisable to run water through the unit when it is OFF ( p. 6),
but in this case freeze prevention is more important.
