( Unless of course the indoor unit already has a disconnect installed from the factory)
tyrap your UF's to the lineset down to the outdoor unit and call it a day...
I have outdoor unit MH080FXCA4A and two of the indoor units MH052FNCA
Here is wiring diagram provided my manufacture
so, I need to run 3 type of cables
#10/2 (2 hot + ground) to power outdoor unit from main electrical panel
#14/2 (2 hot + ground) to power indoor unit from outdoor unit
#16/2 communication cable between indoor- outdoor unit
Also I am planning to use lineset cover to protect my insulated copper, something like this
With your guys help I think i have figured how to run #10/2 cable
electrical panel - double pole 220V 30A breaker - #10/2 armored cable - disconnect switch/box on outside wall - and this 4" peace of cable between disconnect box and outdoor unit
but how about #14/2 and #16/2 between my outdoor unit and two indoor units?
do I install another disconnect box to make transaction between armored 14/2 and UF 14/2, or I just just strip metal wrap from armored cable where it's leaving my exterior wall and put it in UF liquid based conduit and run alone with my lineset in lineset cover
any advice would be greatlly appreciated.
