MCI-9, Coach Heater and Blowers

[Kwajdiver]

Hello,

I want to remove my coach blowers, to make room to install my used ProHeat that I bought at Aracdia.

It appears that the coach blowers are independent of the defroster. Is this true?  If I'm correct, them removing the blowers will have no effect on the defroster.

Is there a water cut off value that I need to close?  Should I remove the condenser?  If so, do I need to connect the water hoses together?

Any thing else I've missed?

As always, thanks for the help.

Bill, you can remove the blowers and leave the heater core if you want.  That's what I did.  The defroster has it's own blower up under the dash.  My Proheat is in the tank bay, but the old Propane furnace is in the blower compartment.  I'm leaving the heater core alone incase I ever want to remove the propane furnace and rig up some OTR heat.  If you want to remove the heater core, just replace it with a piece of hose.  Removing it will give you lots more space.  There are two shut off valves at the rear of the bus to shut off water to the front of the bus.  Shutting those off also suts off water to your defroster.  You won't need to shut off anything.  Just insert a piece of hose if you remove the heater core.

Ross,

Thanks, if it's not raining, I'm going to play around with it tomorrow.

I have an AMGeneral transit that I removed the heater/AC from under the floor (what was really strange [and a waste of money] was that the bus did not have AC, but the gigantic evaporator and receiver dryer were there-do figure?).  The heater core is about 6ft by 16" by 4" thick.  I had it pressure tested and cleaned.  I now have it installed inside the bus on the floor going length wise under my closet/washer dryer with two 14" radiator fans.  I have a ball valve I can get to through a small door in the base of the closet to turn off in summer, but still have the radiator water going to the defroster.  While the radiator fans are a bit noisy, going down the road isn't bad.  The heater is not ducted, just dumps into the hallway through 4 vent registers aimed either way.  When it comes on you can count to 10 a feel heat-very effective.  Keeping the over the road heater element is a good way for going down the road heat, since you don't have the pressures like you do with AC.  Good Luck, TomC
