CONNECTIONS – ELECTRICAL

All electrical work and permanent wiring must be carried out by a qualified person and in accordance with the Wiring Rules AS/NZS 3000 and local authority requirements.

The water heater is supplied with a 1.8 metre lead and plug and requires a 240 V 50 Hz general purpose outlet (GPO) to be located within 1.0 metre of the installation. NOTE: For outdoor installations the GPO must be weatherproof. The GPO must be clear of the flue exhaust, draining water, gas supply pipe and water connections.

The water heater must be properly earthed and the installation of a Residual Current Device (RCD) is recommended for added electrical safety

CAUTION: DO NOT LOCATE CABLES IN FRONT OF OR UNDERNEATH THE BURNER.

Where conduit is mounted to the water heater a 10mm air gap must be maintained from the water heater casing to eliminate possible overheating. DO NOT locate conduits or cables where they will obstruct or restrict removal of panels, access doors etc.

The water heater must NOT be able to operate without the pump running.

The water heater and pump may be supplied from the same electrical circuit, alternatively the 240 volt supply to the water heater may be provided via auxiliary contacts of the pump contactor or relay (if fitted).

Where additional control wiring is connected to the water heater, which is not isolated by the GPO, a suitable warning label must be affixed to the water heater identifying the isolation point for that particular wiring (e.g. by circuit breaker or fuse number and switchboard identification number or location).

THERMOSTAT SETTING

The thermostat is adjustable; the range varies according to the capacity and operation type (refer to the table opposite).

109

147

On/Off

25°C - 95°C

20°C - 80°C

Hi/Lo

45°C - 85°C

0°C - 95°C

For reasons of safety and economy, we recommend that the thermostat is set at the lowest temperature that will provide sufficient hot water. Discuss the thermostat setting requirements with the householder or responsible officer. Refer to “Temperature Control” on page 35.

INTERMITTENT PUMP OPERATION

For applications utilising intermittent pump operation a pump run on timer is fitted as standard equipment to the water heater and must be utilised to prevent nuisance tripping of the high limit thermostat due to heat build up in the heat exchanger. The timer should be set to allow the pump to operate for at least ten (10) minutes.

EXTERNAL CONTROLS

The water heater can be wired for use with an external flow switch, remote control thermostat or a remote time switch.

To connect an external switch, time clock or thermostat to the water heater it is necessary to remove the bridging wire between terminals 1 and 2 of the water heater terminal block and connect the external control across these two terminals(refer to the diagram opposite and to the wiring diagrams on pages 24 to 27).

To connect a flow switch to the water heater it is necessary to remove the bridging wire from between terminals 3 and 4 of the water heater terminal block and connect the flow switch across these two terminals (refer to the diagram opposite and to the wiring diagrams on pages 24 to 27).

Where an external thermostat is utilised the water heater thermostat should be adjusted to a temperature higher than the setting on the remote thermostat (Refer to "Temperature Control" on page 35.
