NOTICE
Precautions when making knockout holes:
▪ Avoid damaging the casing and underlying piping.
▪ After making the knockout holes, we recommend to remove the burrs and paint
the edges and areas around the edges using repair paint to prevent rusting.
▪ When passing electrical wiring through the knockout holes, wrap the wiring with
protective tape to prevent damage.
3 Do the following:
▪ Connect the liquid pipe (a) to the liquid stop valve.
▪ Connect the gas pipe (b) to the gas stop valve.
4 Do the following:
▪ Insulate the liquid piping (a) and the gas piping (b).
▪ Wind heat insulation around the curves, and then cover it with vinyl tape (c).
▪ Make sure the field piping does not touch any compressor components.
▪ Seal the insulation ends (sealant etc.) (d).
▪ Wrap the field piping with vinyl tape (e) to protect it against sharp edges
5 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.
6 Reattach the service cover and the piping intake plate.
7 Seal all gaps (example: a) to prevent snow and small animals from entering the
system.
