If water pipes are frozen, there would not be water flow in the system. Use a heat source (e.g. hair dryer) to unfreeze the frozen components and pipes. Before using the appliance after defrosting contact the Rinnai service to verify possible damages.
1.3.2 OPERATION WITHOUT WATER CONTROLLERS Rinnai continuous flow water heater products do not use a pilot light. When installed and operated, the opening of any hot water tap will automatically start the appliance. Once water is flowing through the appliance the burner will be ignited by electronic ignition.
Water resistance The MC-601 universal water controller is a water resistant device, however excessive exposure to water such as immersion may result in damage to the water controller. Durability of water controllers is improved when positioned outside of the shower recess. Controllers must be installed at least 400 mm above the highest part of a sink, basin or bath.
1.3.5 UNIVERSAL WATER CONTROLLER (MC-601) OPERATION WATE HEATE 'IN USE' INDICATO Indicates that a water heater is delivering hot water. DIGITAL MONITO Indicates the temperature selected. Error messages flash in event of a fault. °C TEMPE ATU E CONT OL BUTTONS CONTROLLE P IO ITY INDICATO Used to select water temperature.

Lock function To prevent tampering and increase the safety level of the product, °C especially for children, it is possible to lock the control panel. To lock the panel it is necessary to press, and keep pressed for about five seconds, the ‘Priority’ keys and the key to increase the temperature (up arrow) (Fig.1).
1.4 TROUBLE SHOOTING Rinnai continuous flow water heaters have a self diagnostic capability. If a fault occurs, an error code will flash on the digital monitor of your water controllers. This assists with diagnosing the fault, and may enable you to overcome a problem without a service call.

2.5 GENERAL SCHEME AND OPERATION PRINCIPLES *Only for REU-E2426W-E model. 2.5.1 OPERATION PRINCIPLES Ignition Press ON/OFF Button of Remote Controller to turn on unit and the remote controller display and priority LED will light up. When a hot water tap is opened the water flow Sensor revolves and sends a pulse signal to the printed circuit board (PCB).
The unit will operate at lower supply pressures but the maximum flow rate may not be achieved. Most installations will use high temperature setpoints which will reduce the available flow rate and heat exchanger pressure drop, and therefore less pressure will be required at the inlet. Contact Rinnai or your supplier for further instruction.
III. The appliance is equipped with power cord and plug: if the cable has to be replaced contact qualified professionals and use original Rinnai parts only not to invalidate the warranty. Do not use adaptors, multiple socket or extension cords.
