Hi,
I have an installer coming tomorrow to commission up my 3.5kW Mitsubishi Electric inverter.
Thanks to the help on here, I've pretty much done all the preparatory work, so just the strength/leak testing, vac, refrigerant top up, etc, needs doing.
I have one final question though. As the pipes will run behind the unit, the tech guys at Mitsu suggested cutting off the thick grey insulation which came with the unit and wrapping in Armaflex tape. Together with brazing the connection, the idea was that this would help the unit fit flush against the wall without compressing the insulation.
I've got the tape but I didn't check what thickness I need to achieve on the pipes to avoid (I guess) condensation. As per the attached photo, its pretty tight to wrap the pipes individually but I think I can get at least 2 warps of the tape, about 6mm thickness.
I just wanted to check that this thickness was sufficient. I wanted to get the bulk of the wrapping done and just leave the tails for the braze..
On a separate note, do you guys use the appropriate cable glands when terminating the SY interconnecting cable between the outdoor/indoor units. I've currently just took the steel braiding and attached it to the earth point just in case.
Any advice appreciated.
Many thanks,
Damian
