independently drained
D. Working Platform (field supplied)
E. Unit Supports (field supplied)
F. P Trap Assembly (supplied) on primary
condensate drain – fit as close as possible to
unit
G. Condensate drain pipe to be pitched down

I.
Electric box with standard 10 A power plug
•
Run 3 core
shielded
communication cable
from indoor coil electric box (Terminals Q
,P, E) to the outdoor unit
•
Run 24VAC from the heater into the indoor
coil electric box (Terminals A1, A2)
3.0 TYPICAL INSTALLATION
Fig. 6 - Typical Indoor Unit Installation
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
•
3 core
shielded
communication cable shall be installed from the indoor unit (Terminals Q, P, E) to the outdoor
unit. One end of the cable 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)
.
