3
Insulate the liquid piping (a, see above) and the gas piping (b,
see above).
4
Wind heat insulation around the curves, and then cover it with
vinyl tape (c, see above).
5
Make sure the field piping does not touch any compressor
components.
6
Seal the insulation ends (sealant etc.) (d, see above).
7
Wrap the field piping with vinyl tape (e, see above) to protect it
against sharp edges
8
If the outdoor unit is installed above the indoor unit, cover the
stop valves (f, see above) with sealing material to prevent
condensed water on the stop valves from moving to the indoor
unit.
NOTICE
Any exposed piping might cause condensation.
9
Reattach the service cover and the piping intake plate.
10

About making field settings
To configure the heat pump system, you must give input to the
outdoor unit's main PCB (A1P). This involves the following field
setting components:
▪ Push buttons to give input to the PCB
▪ A display to read feedback from the PCB
▪ DIP switches (only change the factory settings if you install a cool/
heat selector switch).
