IMPORTANT INFORMATION

INSTALLATION AND SERVICING

Rinnai Wireless Transceivers can be connected to the water heater models listed on the cover page
by the end user in accordance with these Instructions. A qualified tradesperson is not required.

Rinnai Wireless Transceivers are also compatible with some older water heater models not listed on
the cover page of these Instructions. In this case they must be installed and commissioned by a
suitably qualified trades person. Contact Rinnai for information regarding compatibility with older
water heaters.

Regardless of water controller or transceiver installation, all Rinnai water heaters must only be
installed by an Authorised person.

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

Keep this manual in a safe place for future reference. 

All dimensions referred to in this manual are in millimetres, unless otherwise specified.

A WARNING ABOUT HOT WATER

RADIO COMMUNICATIONS

Rinnai wireless controllers are classified as short range radio communications devices and referred
to as Low Interference Potential Devices (LIPD’s) in AS/NZS 4268:2003*. 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 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 4268:2003 ‘Radio Equipment and systems – short range devices – Limits and methods of
measurement’.

Excessively hot water is dangerous, especially for young
children and the infirm. Rinnai water controllers allow you to
control the temperature of hot water to safe levels.

High water temperatures can cause severe burns. Those most
at risk are children, disabled, elderly and the infirm.

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).

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.
