4.0 INDOOR UNIT INSTALLATION
• Indoor coils are supplied with a nitrogen holding charge ranging from 400kPa to 700kPa
•
Connect a suitable pressure gauge to the indoor coil valve to ensure the internal pressure is at least 400kPa
• If the measured pressure is less than 400kPa, check and if necessary repair any leaks found before proceeding
•
Remove the nitrogen holding charge by connecting a charging line with valve depressor
• For SWEAT connection: Sweat off the liquid & suction pipe blanking plates and proceed to pipe up in line with section
6.0 (Refrigeration Charge & Pipe-work)
• For FLARE connection: Un-screw the flare connection, remove the plastic seal and proceed with section 6.0
(Refrigeration Charge & Pipe-work)
• Some heaters may require a transition to modify its starting collar (pop) size to suit the inlet pop size of the ICE indoor
coil. DO NOT REDUCE POP SIZES ON INDOOR COIL or HEATER
•
Ensure minimum specified air quantity requirement passes through the ICE cooling coil at all times
• Ductwork and fittings must be sized to handle the total cooling airflow through the system on either whole home or
zoned basis
• 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
•
The electric box has standard 10 A power cord and plug , please do not cut or modify the cord
• 2 core shielded communication cable shall be installed from the indoor unit (Terminals Q, P) to the outdoor unit
(S1,S2). One end of the shield has to be earthed.
• If the Brivis Heater requires a remote thermistor installed in the supply air ductwork, position it in the supply air starting
collar (discharge pop) of the cooling coil (see Section 4.6)
