Hey everyone,
Its just me again.. Well tomorow will be my first install of a ductless sanyo system . I just need some help with wiring info.. outside unit is 115 v and the inside unit is 240 v. Plus i have to install a disconnect box outside.. I have done many 240 air handlers and all but never ran any mini splits / ductless systems.. If any one has any helpfull schmatics that i can understand or links would be helpfull.. it is a sanyo
inside unit model number KHS0971
outdoor unit CH0971
All new to me electrican ran wire from breaker to outside.. i guess i have to run a wire to get back to indoor unit.. go figure..
thanks
ryan

Not familiar with Sanyo, but I believe you will need a disconnect for the condenser outside and another disconnect for the power running back to the inside unit. Can you not get diagrams off of the Sanyo website, or from the distributor? I would call their tech support and see if they would email something.

the sanyo unit is 115v both indoor and outdoor. do not power outdoor un it with 240v or you will blow both the board and power supply both very costly.
we install about 200 units a year, we had an electrican run 240v to a unit it was not pretty. sanyo model numbers indicate voltage units ending with a 1 are 115v, units ending with a 2 are 208/230v. hope this helps.

its me again...
just trying to get some more info... i know that the outdoor unit is 115volt
model number CH0971.... so does this mean that the inside unit has to be a 115 volt model number KHS0971 ..
i read that it has some kind of dc inverter with it built in i guess. What does that actually do.. Like i said before.. this is my first one i ever delt with.. WOW....????
Thanks again..

every sanyo i have installed has had the indoor unit powered from the outdoor unit, never seperate feeds never different voltages.:cool:
usually run 14-3 to indoor unit from outdoor unit and have a 3 pole disconnect at indoor unit.

Who's your distributor in the DC area?

Page 10 of the install manual clearly shows both 115 volts going to the outdoor unit and then from there to the indoor unit. Hope this helps.

I just bought the same unit for a home office that I'm putting together. I figured that the install should be a snap but I just got word from my wife that our contracter wants $1000 to do the install. (The outside unit will be placed next to the shed) I already have it wired, I've looked at the install instructions and, from an untrained eye, it looks pretty easy.
Any ideas why or what makes this so expensive? I'm ready to cancel my order and just put in a window unit.

I am thinking about the Sanyo Mini-Split as well and My electrician is confused too!
* When you go to Home Depot etc. 14-3 means 14 gauge and 3 wires (Wh, Bl, Red + ground; they don't count the ground!!!!). So I guess you meant 14-2 (Wh, Bl and bare copper ground).
* Re Disconnect Box:
I thought 2-pole disconnect for outside unit is good enough (similar to a central AC outdoor disconnect).
- Does indoor unit need a disconnect?
- Also why 3 pole disconnect?
Please help my electrician! He will wire the Outside disconnect as in the picture below, any opinion?

When it turned out the Fujuitsu I got for a job wouldn't work, thanks to Dice's advice I switched to that Sanyo in the low ambient version. 120V in & out.

Hey everyone
Im back from DC.. Install was easy.. i was just trying to see what voltages were. The guy i work with was saying that outdise was 115 volt and indoor was 240 volt. I set him straight first thing this morning when i showed him the manual / box the units came in.. Its just like wiring a normal a/c with disconnect box... Just need to get 14-3 wire for the terminal wires that go onto 1 2 3 .. Pretty much color coded... If i can find a resonable price i might get one for garage.. As far as our distributer customer / real esatate agent already had.. We just installed... Yea both units were 115 volts....
like someone said earlier if the number ends with a 1 its 115 volt
2 its 230 volt
Well thanks everyone for replys... I think there are pretty easy.. no brazing or nothing.. still have to vacuum line set but how hard is that..
Well again thanks everyone..

Just wondering, what would you have done if the unit did not work on start up?
The problem with these units is finding someone to repair them. I have taken to only working on the ones I have installed. The folks who call me for service who used the other guy must agree to buy a service, maintenace contract with the repair or I will not do the call.
I find these units installed in the most screwed up locations, some I will not venture to service. I kid you not, one was installed hanging from rope threaded through the holes in the mounting feet. The condenser was hanging out the side of a window the ropes were tied around a 2X4 nailed under the window sill. The line set and electric were coming through a wall sleeve from an old package terminal unit. The old units electric was connected to the condenser with the old power cord with a plug end.
I collected a service call after I told the HO to shove a couple of 2X4's behind the unit, condenser air is hard to suck through a brick wall.
Oh did I mention this unit is hanging out a 14th floor window over a busy center city sidewalk.
The HO told me he got the unit installed for $500 by a guy from the Craigslist.org nice!
I did instruct the HO to change the ropes every year, although I think the line set and wiring would save it from hitting the pavement. I bet the unit would work fine just hanging by the piping and wiring.
BTW how does one get the pictures off his new Nextel camera phone, into his computer? I got some real interesting pics saved on this phone.

sanyo does not want filter driers for the units. This will add a metering device to the system and cause the electronic metering device problems. If you need to dry out the lines install fliter dryer with bypass and ballvalves to isolate after cycling system. Hope this helps.
