•
Icebox coils are supplied with a nitrogen holding charge ranging from 400kPa to 700kPa.
•
Connect a suitable pressure gauge to the Icebox 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 connection to condenser refer to the installation manual supplied with the condenser.
•
Ensure minimum specified air quantity requirement passes through the Icebox 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 Icebox electric box (Terminals A1, A2) to the Heater
(StarPro series) or to Brivis Thermostat as required.
•
The electric box has standard 10A power cord and plug, please do not cut or modify the cord.
•
2-core shielded communication cable shall be installed from the Icebox unit (Terminals Q, P, E) to the
outdoor condenser unit (Terminals S1 & S2) with the shield earthed at condenser end only.
.
4.1 Location
•
Choose a location that is suitable for refrigeration piping and condensate drainage.
•
Adequate provision shall be made available for service access.
•
Where the unit is installed the wall of the building shall be capable of effectively anchoring the heater.
•
Never put the Icebox coil unit in the return air part of the duct system, this may result in condensation
forming in the Heater, causing corrosion and damage to vital components.
•
Ensure a minimum of 1m, or preferably 2½ times the duct diameter of straight ductwork, is installed
immediately downstream of the Icebox unit before any divergence or branch-take-offs occur.
Failure
to do so may compromise airflow, system performance and reliability.
•
Icebox shall be mounted on a solid level foundation, i.e. concrete base, to enable proper condensate
removal.
4.2 Area to cut into the wall
Prior to installing the Icebox create a hole in the building wall all the way to ground level to suit location of
the supply and return air pops, refer to ‘Icebox Dimensions’ for cut out requirements. There shall be no
impediment to the structural integrity of the dwelling.

Note:
For the communication cable use 2-Core Shielded Cable only and earth the shield at condenser
end.
