WARNING ABOUT HOT WATER

Hot water can cause scalding. Those most at risk are children and disabled, elderly and

inrm persons. (65°C water can severely burn a child in half a second).

Rinnai have water heater models which limit the delivery temperature to 50°C which signicantly reduces the scald hazard. Temperature limiting devices may also be able to be tted. Contact Rinnai for further information.

Always test the water temperature before use, such as when lling a bath or basin or entering a shower, to ensure it is suitable for the application and will not cause scald injury.

Always supervise children whenever they are in the bathroom or near other sources of hot water. Ensure any hot water taps are closed rmly after use.

WARNINGS & IMPORTANT INFORMATION

Operational Safety Information

IMPORTANT

This appliance is not intended for use by persons (including children) with reduced physical, sensory or mental capabilities, or lack of experience and knowledge, unless they have been given supervision or instruction concerning use of the appliance by a person responsible for their safety� Children should be supervised to ensure that they do not play with the appliance�

To clean your water controller(s) use a soft damp cloth

with a mild detergent�

DO NOT use solvents!

Whilst hot water outlets are open the set temperature may be lowered� However they cannot then be raised above 43°C� In addition transfer of 'priority' between controllers is not possible� These are safety features�

Depending on the weather conditions and the length of the pipe between the hot water unit and the outlet in use, there may be a variation between the

temperatures displayed at the water controller(s) and

the temperature of the water at the outlet�

There is no need to turn the water controller(s) off

after use� However, if you prefer to turn the water

controller(s) off, your selected temperatures to a

maximum of 50°C will be stored in the system memory at all times whilst mains power remains connected�

As a safety precaution, if a Kitchen Water Controller's temperature is set above 50°C, transferring and then returning 'priority' to the Kitchen Water Controller will result in a default set temperature of 50°C being selected� This is a safety feature�

DO NOT push the On/Off button on any Water Controller when the water heater ‘In Use’ indicator is illuminated as this will turn off the water heater causing the water to go cold� Someone maybe in the middle of

having a shower or lling a bath.

FEATURES & BENEFITS

Congratulations on purchasing the latest technology temperature controlled Rinnai continuous ow water heating

system�

•

The Rinnai Continuous Flow water heater products NEVER RUN OUT of hot water� Whilst electricity, water and gas supplies are connected, hot water is available whenever hot water taps are open�

•

Built into the main micro-processor is the facility to LIMIT THE MAXIMUM TEMPERATURE of the hot water supplied� The water temperature may be limited to various values� This is particularly useful when the hot

water unit is installed where young children or the inrm may be using the hot water.

•

The Rinnai Continuous Flow water heater products are Fan-Assisted (power ued) appliances. This makes

them COMPACT, saving both oor and wall space.

•

The temperature of hot water is CONSTANTLY MONITORED by a BUILT-IN SENSOR� If the temperature of the hot water rises to more than 3°C above the selected temperature the burner is turned OFF and only turned ON again when the temperature falls below the selected temperature�

•

The burner lights automatically when the hot water tap is opened, and goes out when the tap is closed� IGNITION IS ELECTRONIC, so there is no pilot light� When the hot water tap is off, no gas is used�

•

'Deluxe' or 'Universal' Water Controllers are available as an optional extra� Depending on the models chosen, these offer the following features:

Bath ll function (Deluxe Bathroom Control Only).

Voice Prompting (Deluxe Control Only).

Clock (Deluxe Control Only).

Up to four water controllers can be tted. See page 9 for details.

 For further information regarding Wireless and Deluxe water controllers please contact Rinnai or visit

www�rinnai�com�au�

•

The "Smartstart®" system when tted can pre-heat the water in the pipe-work between the water heater and

the hot water outlets� This results in water savings and reduces waiting time for heated water at the outlets�

•

Operating NOISE LEVEL IS VERY LOW�

•

ERROR MESSAGES ARE DISPLAYED on the Water Controllers and Status Monitor*, assisting with service� *All models in the range covered by this manual have a “Status Monitor”, except B16,B20 & B26�

•

The Innity 26 Touch (REU-AM2626WDL) water heater model is supplied with one “MC-503” wireless water controller that is pre-programmed as a master controller� Additional ‘MC-503’ wireless water controllers are available as an optional extra� Please refer the separate wireless operation manual for instructions on how to use the supplied wireless water controller�

WARNINGS & IMPORTANT INFORMATION

Rinnai 8 HW_CF OIM

MAXIMUM DELIVERY TEMPERATURES

Rinnai continuous ow water heaters are factory pre-set to various maximum delivery temperatures depending on

model and their intended application� For the majority of applications, the factory pre-set temperature is appropriate�

In the unlikely event this is not the case this setting can be increased or decreased by an authorised person such as a licensed plumber�

NOTE

This does not apply to “50 degree compliant” models� To meet the regulatory requirements the maximum delivery temperature is factory set and sealed�

For model specic information in regards to the factory pre-set temperature of your appliance

refer to "Table 3� Maximum Delivery Temperatures" on page 27� The appliance model number can be found on the dataplate, which is located on the left hand side of appliance�

OPERATION WITHOUT WATER CONTROLLERS

Rinnai Continuous Flow water heater products do not use a pilot light� When installed and operated without water

controllers, the opening of any hot water tap will automatically start the appliance. Once water is owing through the appliance the burner will be ignited by electronic ignition. When the hot water tap is closed and water owing through the appliance has stopped the burner ame will extinguish.

RINNAI WATER CONTROLLERS

NOTE

Other manufacturers water controllers are NOT compatible with Rinnai water heaters� Rinnai water controllers brought in from other countries are also NOT compatible with Rinnai appliances sold in Australia�

Water controllers MUST NOT be used with any Solar Boost water heater�

Water controllers are available as an optional extra� Wireless, Universal and Deluxe water controllers can be used together and will function as described in the Operation Sections of this manual� Refer to "Water Controller

Combinations & Congurations" on page 9 to conrm the maximum number and combination of water controllers that can be tted to your water heater model.

Location

Water controllers must be installed in shaded and clean locations. They should be tted out of reach of children (suggested height from oor to be at least 1500 mm).

Water Resistance

The MC-601Q 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�

NOTE

Controllers MUST BE installed at least 400 mm above the highest part of a sink, basin or bath�

DO NOT immerse the water controller into water�

AVOID direct exposure to water or steam as these conditions may cause a malfunction�

ALWAYS AVOID exposure to water when the battery compartment is open�

When cleaning your water controller use ONLY a damp cloth and a mild detergent�

WATER TEMPERATURE CONTROL

Rinnai 9 HW_CF OIM

Temperature Control

Water controllers allow precise temperature control by the user� When used correctly, the hot water unit will deliver

the selected temperature, even when the water ow is varied, or more than one tap is in use.

Only one MC model water controller can be designated as a ‘Master’ water controller and this is normally used in the kitchen� All the remaining water controllers are designated as ‘Sub’ water controllers and are for use in bathrooms, toilets and laundries� The maximum temperature limit for all ‘Sub’ water controllers is restricted to 50°C to minimise the risk of burns in these areas�

Each water controller can be individually programmed, however the water heater can only deliver one set

temperature at any time. The available temperatures (°C) are as follows:

Water Controller

Temperatures (°C)**

Master (MC) 37, 38, 39, 40, 41, 42, 43, 44, 45, 46, 48, 50, 55*, 60*, 65*

Sub (MC or BC) 37, 38, 39, 40, 41, 42, 43, 44, 45, 46, 48, 50

For hygiene in sanitary areas such as bathrooms, the suggested temperature should be 37°C ~ 43°C�

The above is a suggestion only, as you may nd higher or lower temperatures more comfortable, however

maintaining lower temperatures also helps to save energy�

To obtain water temperatures lower than 37°C, simply open the cold water tap and add cold water until the desired lower temperature is reached�

NOTE

The temperature of outgoing hot water is constantly monitored by a built-in sensor� If the temperature of the outgoing hot water rises to more than 3°C above the selected temperature

shown on the digital monitor or the pre-set limit when water controllers are not tted, the burner

will automatically go out� The ‘in use’ indicator will also go out� The burner will ignite again once the outgoing hot water temperature falls to that shown on the digital monitor (or the pre-set limit of the appliance)

* Temperature may not be available on all installations� Some Rinnai Continuous Flow water heaters can be programmed to deliver higher temperatures from the master water controller, or may be programmed to restrict the maximum available delivery temperature� Contact Rinnai for more details�

** Temperature limiting devices (where tted) may further control what maximum delivery

temperature is available to outlets�

Universal and Wireless and water controllers allow temperature selection only� Deluxe water controllers allow temperature selection, have a clock function and the Deluxe Bathroom water controller has a shower saver / bath

ll function is also available, contact Rinnai for further information regarding Wireless and Deluxe water controllers

or visit www�rinnai�com�au�
