the conditions and regulations applicable to each installation site. Refer to the electrical drawings and specifications for
electrical data.
The electrical controls are housed in the outdoor unit. The electrical installation requirements are generally as follows:
•
The outdoor unit shall be supplied directly from a distribution board
•
An external isolating switch shall be installed adjacent to the outdoor unit
•
Short circuit protection for the unit shall be supplied at the main switchboard using either a ‘D-Curve’ type circuit
breaker (or equivalent), or HRC fuse. Wire fuses shall not be used - check SAA Wiring Rules for “Protection”
sizing and cable sizes. Refer to specification sheet for circuit breaker sizing
•
Do not drill into the cabinet as critical internal components may be damaged during this process
•
24 volt control wiring shall be installed from the outdoor unit to the Heater and or thermostat controller as required
•
Avoid running the control/communication cable near sources of electromagnetic interference such as electrical
motors, transformers, high current cables etc. Use shielded cable if necessary
•
Ensure that power supply is adequate, and phase rotation is correct
5.3 Thermostat Control Wiring
•
All control wiring is 24 Volt, and is required to be installed between the outdoor unit and the Gas Ducted Heater /
Controller in accordance with the wiring instructions supplied with the Brivis Gas Ducted Heater.
•
For any other make of heater (Non- Brivis) contact the heater’s manufacturer.
•
Minimum control circuit wire size is 1.0mm

Note: There is no time delay built into the outdoor condensing unit to prevent compressor short cycling on rapid calls from
the thermostat for cooling. Time delays providing this protection are built into the recommended Brivis Controllers.
When adding Brivis ICE to a system where a non-Brivis heater is installed, it is the installer’s responsibility to ensure that
some form of time delay or other protection is installed to prevent the compressor from short cycling.
Failure to do so may
void warranty.
