4.4 Electrical Connection
The electric box has standard 3 m, 10 A power cord and plug; do not cut or modify the cord
•
24 Volt control wiring shall be installed from the indoor coil electric box (Terminals A1, A2) to the Heater (StarPro
•
series) or to Brivis Thermostat as required
•
2 core shielded communication cable shall be installed from the indoor unit to the outdoor unit. One end of the cable
has to be earthed. See Fig.14.
The unit is pre-wired with a 3-pin plug and lead, and should be plugged into a standard 10 Amp 220 to 240 Volt fixed
switched socket outlet adjacent to the unit, in a convenient location so it can be turned OFF quickly and easily.
Note: A qualified electrician must install the 220 to 240 Volt wiring according to local regulations.
The electricity supply must be 220 to 240 Volts at 50 Hz, and from an authorised power supplier. Generators should never
be used, as their output may be incompatible with, or prone to damage the unit's electronic components.
4.5 System and Ductwork Design
Good duct design and sizing are essential to every Brivis ICE cooling system. Use the Brivis "SuperSizeGuide", Brivis size,
or HB276 for guidance. In general:
The ductwork system shall be designed to ensure the minimum recommended cooling airflow as specified in the
•
technical data, is capable of being supplied at all times.
Ductwork should be airtight and have a minimum insulation rating as specified by local codes; under no
•
circumstances should it be less than a rating of R1.0
•
It should also be properly sized, and curves and bends should be smooth enough to ensure that the air flows through
efficiently, quietly and with minimal resistance
The registers and diffusers should be large enough and of good design. They should minimise noise, while providing
•
the correct distribution pattern
The positive return air system should be fitted with a grille large enough to accept the full air capacity of the system at
•
low noise levels
Adequate air filtration must be provided
•
If the system uses high level outlets (e.g. ceiling diffusers), then the return air inlet should be at a low level
•
Note: It is important that all ductwork and fittings be insulated. It is mandatory under some building codes to also install
fire rated duct. Check with your local authority.
4.6 Brivis Heater Thermistor position (if applicable)
Mount heater thermistor in the discharge (outlet) pop of the cooling coil
•
•
Drill a 3/4" (20mm) diameter hole through the top of the evaporator coil's outlet pop
•
Carefully insert the thermistor assembly (probe end first) into this hole and secure using the two screws provided
Ensure that the thermistor plug is facing upwards and is accessible for servicing
•
Connect the thermistor extension lead from the heater to the thermistor assembly and ensure that the plug is
•
connected securely
Ensure that the thermistor extension lead is secured to timbers or duct outer casing to prevent damage
•
4.7 Filtration
A filter must be fitted into the system, and should be easily accessible for regular cleaning. Please refer to the guidelines
for return air filter grilles accompanying the Gas Ducted Heater.
