You forgot the first part.M]314.2.4.1Ductless mini-split system traps.
Ductless mini-split equipment that produces condensation shall be provided with an in-line check valve located in the drain line or a trap.

So which is it, does 314.2.4.1 trump 314.2.4 ???You forgot the first part.
[M]314.2.4Traps.
Condensate drains shall be trapped as required by the equipment or appliance manufacturer.
[M]314.2.4.1Ductless mini-split system traps.
Ductless mini-split equipment that produces condensation shall be provided with an in-line check valve located in the drain line or a trap.
I thought the same. Totally ambiguous and open to interpretationSo which is it, does 314.2.4.1 trump 314.2.4 ??
Manufacturer trumps all. Pretty simple, they designed it and know what it contains internally. Some units have a P trap internally. So whatever the manufacturer specifies, just like UL listed trumps NEC.So which is it, does 314.2.4.1 trump 314.2.4 ???
Gotta love regulations, they can mean anything anyone want's them to.
I'm curious how the answer to this plays outIf the array for this unit were to be installed on a house then what would be the best way to install rapid shutdown when there is no inverter? I have a 12k btu unit on the way. I'm debating on having the array ground mounted or on the roof. The roof would be idea, but I'm not entirely sure about the rapid shut down requirements.
Traps are required in split systems when the evap coil is in the negative side of the systems airflow, for example an air handler with the evap coil below the fan. If the evap sits on top of the furnace or air handler (in the positive side) it does not require a trap. The reasoning behind it is because if the coil sits in the negative side, air will be pulled in through the drain port of the coils drain pan and prevent water from draining, gurgling action coming into the pan. In the positive side it's forcing air out through the drain port and the water goes with it. Traps on mini split drains are functionally not required but are enforced by some municipal codes.So can someone explain to me why a mini split does not require a u trap but a regular split system does.
Its at the my "local" shippers dock. They'll be bring it out here next Thursday.FYI
My DIY 24k warranty replacement is supposedly in cue for shipment. Guess SS got or is now expecting soon some stock.
Never in my life have I seen teflon tape put around the outside of any fitting......pretty good video other than that. You notice they did not show her putting the head unit up while guiding the tubes/wire through the hole....almost impossible by yourself.And the video reveals two things. I noticed, well, either Kelly is hobbit-sized, or the indoor unit looks REALLY big like my 24k.
So I looked it up, the non solar 9 and 12k featured in the video use the 42" inch wide head unit / indoor coil like the solar 24k (the solar 12k uses a 33" inch wide head). I guess that contributes to their higher SEER2.
Second, why there is no non-solar 24k in the line up - the SEER2 would be the same / don't hook up solar to a 24k and boom you have it ?
I did it. I first taped the refrigerant lines, com/power wires and drain hose together to make feeding easier. I pre-fed the long drain and com/power cable through the hole, and then lifted the unit up and guided everything through the wall hole, while holding the air handler unit up near the bracket. The weight of the cable and hose helped draw themselves through the hole. Once everything was through the hole, I hung the air handler on the top of the bracket, wiggled it around to get everything seated where it belonged, and it snapped it into the bottom clips.Never in my life have I seen teflon tape put around the outside of any fitting......pretty good video other than that.
