Brian,
You have a Liberty that will have systems and bay layouts like a lot of the newer ones. There have been changes over the years and improvements, but their systems have been robust and worked well so the fundamentals are good. Ask away if you have questions. The Prevost web site http://prevostparts.volvo.com/technicalpublications/en/wiring.asp is a good place to start although the documentation on older coaches is not as good as later models for chassis questions.
Your coach when originally built may have had a motor driven AC electric generator in place of an inverter, it likely had a converter or pair of converters for battery charging, and maybe some DC electric panels located in three or four places in the house portion of the bus instead of all located in bay 2 driver’s side, but the rest of the systems are likely to be the same or similar to the Liberty coaches built for decades
Looks good.

I will got camera out to take pictures. off charger. Batteries shot. So another run to get batteries. Side note: They make a inside unit that looks like a picture that hangs on wall. I plan on enclosing mine in the cabinets. Rite now they are free hanging as I am still under construction. That time is fast aproaching. Enclosing that is. Condensors are located in spare tire compartment and old condensor bay. They make condensors that will handle multiple evaporators. Up to 4. Bob

just ran a serial # last week showed 99 model . My brain said impossible. Was corrected to find out Detroit built the engine thru 2000 in both mechanical and even DDEC IV. My lesson of the day. Was in a friends 92 Prevost he needed help on and it is mechanical not DDEC. go figure. Bob

Welcome Brian and all new members. Invite your friends and get them to participate.
We are still working out the bugs and anticipating getting the other modules up and running so be patient with us.

Bob – thanks for sending the message through!
Tom – thanks for resetting my registation!
I have been perusing the site for a couple of days and it looks nice.
Glad to be aboard,
Brian

Bob,
Tom and I have to get with the web guru to figure out if we can use PMs. If a member allows his email to be used he can receive messages via email. All anyone has to do is clickon their name on a post.
If a member does not allow an email address to be used right now we have no option unless Tom knows of one.
I am still not satisfied with the workings of the system that supposedly gets us to the latest posts so we know we still have glitches to address. Keep reminding us of needed improvements or fixes. Especially Tom. He is old and can’t remember stuff.

Mini-split are inverter technology. so 7amp rating is max rating. no start up to like 20 amps roof tops. The fan and compressor speed adjust to load requirements. Actually on Ac the 9000 16 ser unit max draw is 6.5 amps no start up surge. They are hard to get use to. when you turn them on the fan does not start on high. It gradually ramps up over a couple minute when freon (cooling ability) becomes available. If we ran everything in our coach cooling. 2 each 9000 units and 1 each 12000 units zoned tne maximun load would be 21 amps max or equal to start up load of one large roof top that would run at 15 amps and not near cool coach. $$$ I have $1450. fourteen hundred fifty dollars in my zoned system. Ser is the efficiency rating of the units placed on the by federal agencys. the lowest is eleven (worst) least efficient. It is the concensus of hvac guys most roof tops would be a 9 if there were such a number. Roof tops are easy to install. Easy source for general info. E-bay just put in mini-split read spec… By the way same unit = same amout of heat. one does it all. Have friend in Alaska using in his coach. Good down to single didgets-due to use of 410A refrigerant. Have tested to 20’s my self and to 100 on high side. so far 3rd unit would not have been needed. Good to have it if you need it. Bob

That would make a great postcard John.

Bob,
Pictures? Links to manufacturer’s site?
Just to offer some Cruise Air data…….We have 4 units, and on 100 degree days 2 units will NOT pull the coach below 85 or so. Just to be sure I am not misunderstood, 100 degrees is the outside temp and adding to the ambient outside is the impact of the sun also working against the AC units.
Current draw (run, not start) is about 13 amps per unit.
Three Cruise Airs will get the temps into the 70’s, but to get to 70 and to get all units cycling at that temp in the above conditions requires all 4 units. Once there, 3 units will maintain the temp. Windows will be sweating outside.
