Hey guys, installing a 24k Ideal Air mini-split system. I have lots of questions as this is my first time working with an ac unit, so I will continue adding to this thread as I get further into the install. My first 2 questions are:
1. Should I drain the water from the inside unit to the outside, or should I drain it into a reservoir and use it? I am not sure how much water one of these units can produce, but I am in a 10x22 garage without a dehumidifier at the moment.
2. I see the outdoor condensing unit need its own dedicated 15amp breaker. Do I connect the inside unit to this same circuit or should it be wired up to an existing circuit?

Thanks for taking the time to help out!

Well first off it should have come with instalation instructions, the condensate will be constant flow of water as long as the unit is running ok ready

1. location of your airhandler, drill the hole ,if came with sleve put it in hole

2. go outside unroll the tubing( LINESET) ( both lines ) step on end and roll out

3. take electrical tape or duct tape and tape the lines together along with your thermostat wire

4. now run your tubing in the hole to inside, leave enough for your connections and play so when you set the airhandler on the bracts you dont kink the tubing

5 run your drain.if P trap is required make sure you install one

6. now run your electric yes you must use 2 dedicated circs.

7. now hang your A/H and install tubing/drain /electric to unit.

8. set the condenser on a pad ,make sure you set it at least 1 ft from the buidling and have access to the service ports and electric.also if the fan is pointed in the up direction it can not be installed over a window , and it needs at lest 8ft high unabstructed airflow

9. install service disconnect on building at least 2ft high

10. install copper lineset to condenser unit. after that install your t/stat wires

11. now take your whip ( sealtight) line voltage and hook it up.

12 I will give you start up prceedure when you are ready if you dont have a vacum pump ,I will explain how you will bleed the system (get the air out)

Oh FYI the copper lineset is very soft copper so when bending ,take your time make big bends and form them small a little at a tim , KINK in lineset will screw you up big time

Hey thanks for all the help. Should I run the drain tube outside somewhere? I dont have a drain in the garage, dont know how far to have it go from the outside and wondering if it will freeze in the winter. Also, should both the air handler and condensor be on 220v circuits?

the 220 volts go into the condensor, the condensor has 3 -4 control wires which go into the evaporator(head) unit. should be a L1 and L2 for power, then a side for your control wires.

the drain can be ran straight outside, if you live in a place that gets cold enough, yes it can freeze. Draining into a plumbing drain is ideal, or you can use a condensation pump.

yes the condensate has bad exhaust fumes trapped in it it will be bad for your plants. if you dont want to go outside with it you may be able to add a wye adapter to a drain and stick it in there.
i thought mini splits had their own condensate pump built in, all i think needed may be some vinyl tubing . The P-trap is usually used with air handlers]
edit: im thinking of a ductable ductless, the minisplits you need to gravity drain or if your in a basement you run it down into the condensate and then run vinyl tubing from the pump to wherever. the thing fills up and then hits a float switch and pumps it outside. you may be able to use the condensate pump to get rid of waste water too, they usually have 4 holes one on each corner.
dont buy a cheap crap one because if it fails you will have lots of water, consider putting a pan under it if you get a cheap crap one. (harbor freight has shitty ones)

they don't usually come with a pump, you just run the drain out the back and let it drain if you can. But yeah, The water that comes off the evaporator has ran over copper and aluminum before you collect it, also a film will build up on the drain pan. Bad microbes breed in that environment, so that water is no good to use. There is no exhaust, so no exhaust fumes,FYI

my b thinking about high efficiency boilers; new to the hvac/r scene :) you are right though!
some places now require a neutralizing trap to change the condensate pH to be more enviro-friendly :P

would not tie drain into exsisting plumbing waste line, unless you do a indirect tie witch is still a NO NO, gases created by waste line might not let the line drain , this is why there is a strict boca drain code .\,yes it will freeze and make mounds of ice,I suggest you dig a 2x2 fill with drainage stone , cut line above your snow line and use heat tape on the exposed portion of your condensate line , , and yes if your mini is powerd first through the evap(inside) then one circut (breaker) but dono you should scan the units wire schematic if you want better help.not every system is wired the same. and I never heard of that brand.

Ok have everything ran and installed except electrical. Theres a line with the other hoses from indoor unit to outdoor unit, and then a seperate whip with wires on both ends. It looks like in the manual I am supposed to hook up the power to the indoor unit (the 220v one) and the outdoor unit is powered by the indoor one. Is this right?

dono need wire diagram to help. but witch ever unit outdoor or indoor has 2x L1 and L2 that is your feed comming in to witch ever unit has all 4 ,So L1- L2 In that is your line voltage in then L1-L2 out goes to what ever unit has only 1x L1- L2. that as much as I can help good luck, or might sat L1- L2 Load 1 Load 2
