Hi Guy's,

Most ductless split mfg's won't recommend mobile installations for 2 reasons.

1) as stated above, the copper lines and connections are not designed to resist the stress of movement.

2) The evaporators are built with very shallow condensate pans which could spill and damage furniture and walls.

This doesn't mean that you can't.... Just don't ever tell them what you installed it in! Lol

Also to answer the DC compressor question, the inverter boards within the units are very elabrate. They control

a very wide range of compressor speeds as well as fan speeds to optomize efficency. It would be very hard to mimmic

this range with straight DC current within your coach.

This year has been a record breaker for us with Ductless Split installs! 98% of them in homes and and 2 so far in an

Ice Cream truck.. Next Monday we start a quad Sanyo install for a home owner in Cape May.  A 9,000 btu and 3- 7,000 btu's.

utilizing one 30,000 btu quad condencer. Each zone is self controlable and all the evaporators have UV air cleaners within.

So far this year all the Sanyo's we installed were 19 SEER+ too.

Bobby, Glad to hear your happy with your Ductless Split!

Good Luck

Larry, can you clarify what "takes itself off-line" means?  5 minute wait to auto reset, hard reset by a technician, buy  a new control board...

thanks, Brian

sorry, been travelin'

I believe the last of these mini's we specified were Carrier. They went into a auto reset that was more like 45 minute. I will have to go into the manual. My point was that these do like a steady voltage with no surges. In the instance I mentioned, city power, then generator power, then city power again, then city power again. All with a large commercial genset (250 KW) but in the middle of an ice storm. Everything was automatic.

Holy S*** I open one of the Sanyo's  man the electronics on those are out of this world why would anyone even consider installing one in a bus, are all the inverter type made that way it blew me away all the circuitry on it I'll pass I don't care how much cool air they make that looks like a fortune to have one fixed 

good luck

You don't fix them you replace them

Kind of like the light bulb in your tail light

They really are pretty cheap and when properly installed they pretty much don't need any thing to keep running

We are after all a disposable society

last report. Hottest day of year yesterday. weather man said was and hopefully will be one or twice a year occurrence.  Got up to 76 in coach with one unit (9000 ); 0n kicked 2ND on and minutes later down to 70.  parked in steel building no ac or heat for that matter ; building in the sun. 97 degrees and humidity in 80's.Heat index 117      Time will tell on durability..   I still like mags and spark plugs or basic diesel non electronic  but that's not here anymore. so let's go for the ride with new technology: probably disposable.  Bob

Still see no pictures from anyone on their installations. What's up with that?

I'll go first.  I was digging to see if I had some good pics.  I'll post a few tonight as I find them.  I will also make an effort to get some better shots for your critique.  This one is a Sanyo 12K BTU mounted over the table which is built over the wheel well.  It is not in the way at all and has been in operation for 3 years.

I would be quite interested in seeing pictures of where folks have installed the condenser units to get proper airflow.

Darrel found some evaporators you can conceal for the Sanyo's has anyone here used those ? he is not going with the evaporator that go on the wall for some reason and the ceiling units take up to much room on the top

good luck

Bob from the back woods; soft ref grade copper with attention paid to any place it might rub through insulation with a little extra rubber padding to prevent damage to copper. Anchor well to prevent movement;spray foam tight inaccessible areas. Just my way.  Bob
