WARNING ABOUT HOT WATER

Heated water can be dangerous, especially for young children and the infirm.

Water temperatures above 50°C can cause severe burns instantly and may even result in death.

Those most at risk are children, disabled, elderly and the infirm.

Hot water at 65°C (a very common hot water temperature in Australia) can severely burn a child in less than half a second. At 50°C it takes five minutes.

ALWAYS......

Test the temperature of the water with your elbow before placing your child in the bath, also carefully feel water before bathing or showering yourself.

Supervise children whenever they are in the bathroom.

Make sure that the hot water tap is turned off tightly.

CONSIDER.....

Installing child proof tap covers or child resistant taps (both approaches will prevent a small hand being able to turn on the tap).

Setting your appliance at a maximum temperature of 50°C (Contact Rinnai Australia).

NEVER…..

Leave a toddler in the care of another child. They may not understand the need to have the water temperature set at a safe level.

Rinnai Australia 4 Operation Manual

FEATURES AND BENEFITS

Congratulations on purchasing the latest technology temperature controlled Rinnai continuous flow 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 infirm may be using the hot water.

• The Rinnai Continuous Flow water heater products are Fan-Assisted (power flued) appliances. This

makes them COMPACT, saving both floor 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.

• This Rinnai Continuous Flow water heater product 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.

• 'Deluxe' or 'Universal' Water Controllers are also available as an optional extra. Depending on the

models chosen, these offer the following features:

• Bath fill function (Deluxe Bathroom Control Only).

• Voice Prompting (Deluxe Control Only).

• Clock (Deluxe Control Only).

• Up to four water controllers can be fitted. See page 10 for details.

• The "Smartstart®" system when fitted 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”.

Kitchen

Bathroom

To clean your water controller(s) use a soft damp cloth with a mild detergent.

Do Not use solvents!

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.

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.

There is no need to turn the water controller(s) off after use. However, if you prefer to turn the water controller(s) off, 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 Controller's temperature is set above 50°C, transferring and then returning 'priority' to the Kitchen 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 Controller when the ‘Red’ 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 filling a bath.

Rinnai Australia 8 Operation Manual

GENERAL WATER CONTROL INFORMATION

NOTE NOTE

RADIO COMMUNICATIONS

Rinnai wireless water controllers are classified as short range radio communications devices and referred to as Low Interference Potential Devices (LIPD’s) in AS/NZS 4268*. As such, they operate in the same radio frequency spectrum as many other devices classified as LIPD’s such as garage door openers and keyless automobile entry systems. Although interference with other LIPD's is unlikely, it is not guaranteed interference will not occur.

Rinnai wireless water controllers must not be used in the vicinity of other devices if radio interference with such devices could result in a dangerous situation, unless it is verified that interference will not occur. Possible examples are medical devices and fire alarms.

*AS/NZS 4268 ‘Radio Equipment and systems – short range devices – Limits and methods of measurement’.

WATER RESISTANCE

The MC-503RC Wireless water controller is a water resistant device, however excessive exposure to water such as immersion may result in damage to the controller.

• DO NOT immerse the 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.

MAXIMUM DELIVERY TEMPERATURES

Rinnai continuous flow 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 preset 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.

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

Factory pre-set delivery temperatures for the various models are as follows:

MODEL NUMBER MODEL NAME FACTORY “PRE-SET”

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 flow is varied, or more than one tap is in use. 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:

Master Controller (used in kitchen):

37, 38, 39, 40, 41, 42, 43, 44, 45, 46, 48, 50, 55°C* 60°C*, 65°C*, 75°C*

Bathroom Controller (used in bathrooms, ensuites, toilets and laundry):

Hot Water Delivery: 37, 38, 39, 40, 41, 42, 43, 44, 45, 46, 48, 50°C

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

Rinnai Australia 9 Operation Manual

GENERAL WATER CONTROL INFORMATION

Suggested temperatures are:

Kitchen 50°C ~ 55°C*, Shower 37°C ~ 43°C

* Temperature may not be available on all installations. Rinnai water heaters can be programmed to deliver higher temperatures via the kitchen controller. Contact Rinnai for more details.

These temperatures are suggestions only. You may find higher or lower temperatures more comfortable. Maintaining lower temperatures helps save energy. To obtain water temperatures lower than 37°C simply add cold water.

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, 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.

Wireless water controllers can be fitted along with wired 'Universal' and 'Deluxe' water controllers. Wireless and Universal water controllers allow temperature selection only. Deluxe water controllers allow temperature selection, have a clock function and on the Deluxe Bathroom water controller BC100V a shower saver / bath fill function is also available.

NOTE

TRANSFERRING PRIORITY BETWEEN WATER CONTROLLERS

To control the water delivery temperatures when using two or more controllers it is necessary to have priority transferred to the water controller you wish to use.

An illuminated Transfer indicator confirms that the desired water controller is in control of the water delivery temperature.

If the Transfer indicator is not illuminated press the ‘Transfer’ button to transfer priority to the desired water controller.

The Transfer indicator on the water controller will now illuminate to indicating that priority has been transferred and that the water heater is ready to supply hot water once a hot water tap is opened.

Whilst hot water taps are open transfer of 'priority' between controllers is not possible. This is a safety feature.

HOT WATER CONTROL Temperatures higher than 50°C should only be able to be selected on the controller labelled ‘Master’ controller (used in the kitchen), not on those labelled ‘Bathroom’ controllers. This helps minimise the risk of burns.

The wireless transceiver has been incorrectly assigned if temperatures in excess of 50°C are able to be selected on controllers used in bathrooms, ensuites, toilets and laundries. Re-assign the wireless transceiver if this is the case. See “UN-ASSIGNING AND RESETTING WIRELESS WATER CONTROLLERS” on page 36 and “INSTALLING WIRELESS WATER CONTROLLERS” on page 34

USING CHILD LOCK FUNCTION

The Child Lock function is designed to prevent small children or the infirm from operating the wireless controllers.

To Activate the Child Lock

To activate the Child Lock function press the button for 3 seconds. The Child Lock indicator will illuminate to confirm that the function is now active. Once activated only the initiating controller can then deactivate this function?

To Deactivate the Child Lock

To deactivate the Child Lock function press the button for 3 seconds. The Child Lock indicator will go out to show that the function is no longer active.

Child lock only applies to the water controller initiating the function and can be activated / de-activated regardless of priority status or whether the water heater is in the ‘On’ or ‘Off’ condition.

While the child lock is activated only the ‘Child Lock’ control and the ‘Off’ control are functional from that controller.

When the water heater is turned ‘Off’ while Child lock is activated it can not be turned ‘On’ again from a controller where the Child lock is activated.

If the water heater is turned ‘Off’ whilst hot water outlets are open it can not be turned back ‘On’ until all hot water outlets have been closed.

NOTE

ABOUT THE SMARTSTART® PRE-HEAT SYSTEM

Preheat Function

The “Preheat” function works in conjunction with various Rinnai water heater models and the separately installed and optional Rinnai “Smartstart®” module.

When the “Preheat” function is activated and used in accordance with these instructions, water in the pipework connected between the water heater and the hot water outlets in your house is warmed before any outlets are opened. This results in water savings and added convenience.

The preheat function is activated as follows:

1. Ensure that the hot water unit is on (temperature digits are displayed in the digital monitor ).

If more than one controller is fitted press the ‘Transfer’ button to pass on priority to your desired controller. The ‘Transfer’ indicator will illuminate to confirm that priority has been assigned to this controller and that the hot water unit is ready to deliver hot water.

2. Select the desired temperature using the 'Temperature' buttons until the required

temperature is displayed in the digital monitor .

3. Press the ‘Preheat’ button once. The ‘Preheat’ indicator and the ‘In Use’ indicator will

illuminate, signifying that the preheat system has been activated.

4. Wait approximately two minutes before opening an outlet. This will allow the water in the

pipework to be warmed.

The waiting time may be longer or shorter than two minutes depending on your particular installation configuration.

The preheat function is cancelled 5 minutes after activation and the ‘Preheat’ indicator will go out. This is to conserve energy. To reactivate, simply repeat steps 2-4 above.

Other Water Controller Functions

Water controller functions such as temperature control and transfer of priority between multiple controllers are not affected by the operation of the preheat. Such functions are described in the applicable sections of this manual.

Rinnai Australia 14 Operation Manual

* If the ‘Preheat’ button is pressed and the ‘Smartstart®’ preheat unit is not

RINNAI WIRELESS WATER CONTROLLERS

A wireless water controller installation utilises a 'transceiver' and up to 4 wireless water controllers. Unlike most remote control systems, there is 'two way' communication between the transceiver and controllers. The 'transceiver' is connected by electrical cable to the water heater. The 'transceiver' transmits control signals received from the wireless controllers operated by the user to the water heater. The 'transceiver' transmits operational 'status' signals from the water heater which are received by individual wireless controllers to ensure controller displays reflect the operational status of the water heater.

Fittings

Wireless water controllers can be installed in conjunction with Universal and Deluxe wired water controllers and will function as described in the Operation Section of this manual. Refer to page 10 to confirm the maximum number and combination of water controllers that can be fitted.

Master and Sub controllers and temperatures

Only one wireless or wired controller can be designated the 'Master Controller' (MC). This controller is normally used in the kitchen and usually has a maximum temperature of 55°C, is sufficient for almost all kitchen applications. Temperatures higher than 55°C are possible but usually unnecessary and will result in higher gas use and increase the risk of burns. Some conditions regarding Master Controller maximum temperatures are as follows:

• Temperatures of 55°C or higher can only be selected on the controller designated as Master

Controller (MC) if the transceiver 'Max Temp' is also programmed to 55°C or higher.

• The temperature of hot water delivered is always limited to the maximum temperature programmed

into the water heater itself. For example, if the transceiver maximum temperature is programmed to 55°C and the water heater is limited to 50°C, the maximum temperature that the water heater will deliver is 50°C. In this case 55°C will be displayed on the wireless Master Controller until a tap is opened after which the display will revert to 50°C.

The water heater maximum temperature cannot be adjusted by the user.

These adjustments can only be carried out by a qualified and licensed tradesperson.

The remaining controllers are designated 'sub' controllers and are for use in bathrooms, toilets and laundries. The temperature limit for all 'Sub' controllers is always 50°C to minimise the risk of burns in these areas.

Adhesive labels are included for individual identification of wireless controllers as master (Kitchen) or sub (Bathroom No.) controllers. These labels are usually placed on the top back of the wireless water controller body.

Water controllers, transceivers and water heaters do not contain user serviceable parts and must only be serviced and repaired by an authorised person.

POSITIONING OF TRANSCEIVER AND WIRELESS WATER CONTROLLERS

The water controllers must be installed in shaded and clean locations. The water controllers and the transceiver should be fitted out of reach of children (suggested height from floor to be at least 1500 mm).

The water controllers are water resistant, however, durability is improved when positioned outside the shower recess. The water controllers must be installed at least 400 mm above the highest part of a sink, basin or bath.

The MC-503RC Wireless water controller is a water resistant device, however excessive exposure to water such as immersion may result in damage to the controller.

• DO NOT immerse the 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.

The transceiver comes supplied with a 1.5m length of communications cable. The transceiver’s antenna is located in the top. For the best results mount the transceiver so the top of the transceiver is higher than the top of the water heater.

In some cases building construction and design can reduce signal strength and it may be necessary to locate the transceiver in a central location inside the building. Take the signal strength into consideration when determining the best location for both the transceiver and the wireless water controllers.

HORIZONTAL OBSTRUCTIONS

AS/NZS 5601 ‘Gas Installations’ stipulates a minimum horizontal clearance of 500 mm between a building structure and obstruction facing the terminal. For Rinnai external continuous flow water heaters such a building structure must ‘obstruct’ the full front cover height of the appliance, or extend vertically above and below the front cover. There must be no partial obstructions to the front cover of the appliance or any other parts of the appliance casing. This will avoid the appliance failing to operate under windy conditions.

MULTIPLE INSTALLATIONS

Dimension ‘h’ above does not apply when multiple Rinnai external water heaters of the same model are installed on the same vertical face with flue terminals at the same height. Under these conditions appliances can abut each other as shown. The total gas consumption of all appliances applies when determining other clearances.

INSTALLING WIRED AND WIRELESS WATER CONTROLLERS

As supplied the water heater is not pre-wired for the installation of wired controllers or smartstart systems, however it can be modified to do so, contact Rinnai for the parts and procedures to enable these options.

When installing combinations of both wired and wireless controllers, all wired water controllers MUST BE connected before the wireless water controllers are assigned to a transceiver channel.

Refer to page 10 to confirm the maximum number and combination of water controllers that can be fitted

Wired water controllers can ONLY be added to an existing wireless installation when:

• All wireless transceiver channels have been un-assigned.

• All wireless controllers have been reset.

See “UN-ASSIGNING AND RESETTING WIRELESS WATER CONTROLLERS” above.

When the wireless transceiver is installed it automatically detects any wired water controllers already connected to the water heater.

The LEDs of the channels assigned to wired controllers will slow flash. The channels for wired water controllers are assigned in sequence as follows:

MC100V or MC91 (programmed as a Master Controller) will automatically be assigned to the MC channel.

BC100V or MC91 (not programmed as a Master Controller) will automatically be assigned to an available channel other than the MC channel.

Install the wireless water controllers to any of the unassigned channels following steps 1 to 8 on page 35.

COMMISSIONING

TESTING

1. Before final connection of the water heater purge gas, hot water and cold water supply lines. Swarf in either the gas or water supplies may cause damage.

2. Turn on gas and cold water supplies.

3. Test for water leaks and gas escapes near the unit.

4. Isolate gas supply. Remove test point screw located on the gas inlet connection and attach pressure gauge.

5. Turn the power 'on' at the power point socket and turn on gas.

6. Ensure controllers are 'ON', select the maximum delivery temperature and open ALL available hot water taps including the shower. If water controllers are not fitted, simply open all available hot water taps. (CAUTION: Ensure building occupants do not have access to hot water outlets during this procedure.)

7. Operate ALL other gas appliances at their maximum gas rate, in accordance with manufacturers instructions.

8. With all gas appliances in operation at maximum gas rate, the pressure should read between

1.13 - 3.0 kPa on Natural Gas. On LPG the pressure should be 2.75 - 3.0 kPa. If the pressure is lower, the gas supply is inadequate and the appliance will not operate to specification. It is the Installers responsibility to check the gas meter, service regulator and pipe work for correct operation/sizing and rectify as required. Note that the gas regulator on the appliance is electronically controlled and factory pre-set. Under normal circumstances it DOES NOT need adjustment during installation.

9. Close hot water taps including the shower.

10. Inspect and clean the strainer located on the cold water inlet connection. This procedure may need to be repeated to ensure the strainer remains clear, especially on new installations.

11. If water controllers are fitted, it is necessary to test their operation through the complete range of functions (refer to the Operation sections of this manual).

12. Confirm the hot water delivery temperature(s) using a thermometer. If controllers are fitted, ensure temperatures exceeding 50°C cannot be selected on bathroom or ensuite controllers. Refer to the section ‘Delivery Temperature’ below for more details.

13. After testing is completed, explain to the householder the functions and operation of the water heater and water controllers (if fitted). Ensure the “PRODUCT RECORDS” on page 42 of this manual is filled in and that the booklet is handed to the customer. Reminding the customer to complete the Warranty Card and forward to Rinnai.

DELIVERY TEMPERATURE

"50°C Compliant" appliances are 'factory set' to deliver a maximum temperature not exceeding 50°C. However, they have an incremental adjustment mechanism that allows the installer to increase the appliance delivery temperature incrementally from the 'Factory Set’ value to temperatures exceeding 50°C. This is intended to enable compensation for temperature losses in the pipe-work between the water heater and any outlets and achieve the required temperature at the outlet. Instructions for incremental temperature adjustment are located in the instruction pocket inside the appliance front cover.

For all other models

Rinnai continuous flow 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 preset temperature is appropriate. In the unlikely event it is not this setting can be increased or decreased by the installer. Instructions for changing the maximum delivery temperature are located in the instruction pocket inside the appliance front cover.
