Rinnai Australia 36 Installation Manual
WATER CONTROLLER INSTALLATION
CONNECTING COMMUNICATION CABLES TO THE WATER HEATER
Communication cables connect the water heater to water controllers and operate at an extra low
voltage (12 Volts DC) which is supplied from the water heater. Communication cables are supplied
with the water controllers (15m) and are fitted with spade terminals for connection to water heater. Up
to two cables can be connected directly to the ‘Ezi connect’ cable connector at the water heater.
Extension cables are available from Rinnai. Alternatively, two core sheathed (double insulated) flex
with minimum cross sectional area of 0.5mm² may be used. Cable lengths must not exceed 20 metres.
To connect up to two cables to the 'Ezi connect' cable connector
DO NOT attempt to connect cables to the 'Ezi connect' cable connector at the water
heater unless the electric power to the water heater is switched ‘off’ otherwise damage
to electrical components may occur.
1. Isolate the electric power supply by switching the power point off and removing the power plug of
the water heater from the electric power socket.
2. Remove the retaining screw of the 'Ezi connect' cable connector at the base of the appliance.
3. Swing the 'Ezi connect' cable connector door open and thread the cable through the weather seal
of the cable access hole in the direction shown allowing sufficient cable length so that the
sheath of the cable can be secured with cable clamp supplied with the transceiver.
4. Loosen screw terminals & and connect the cable spade connectors to these terminals and
re-tighten. Polarity is not important, either wire colour can be connected to either terminal.
5. Return the 'Ezi connect' cable connector to the original position taking care not to damage cable
wires in the process and replace the retaining screw .
Connecting Three or Four Controllers
Repeat steps 1, 2 and 3 above.
To connect three or four cables, separate all the cables to be fitted into
pairs. Cut off the existing spade connectors from each pair and re-
terminate each pair into a new spade connector (available from your
local electrical component retailer) so that there are only two sets
of spade connectors (4 spade connectors in total) to be terminated.
Repeat steps 4 and 5 above.
