A. Place a bucket underneath the coach, where the
Aqua-Hot’s Drain Valve is located.
B. Remove the Aqua-Hot’s Radiator Cap and pour 15
gallons of a 50/50 solution of water and antifreeze,
reference figure B1.
C. Place the radiator cap back onto the Aqua-Hot and tight-
en.
D. Close both pump and return manifold valves, reference
Figure B2
E. Activate the Bedroom Zone Pump.
F. Pressurize the system by applying air pressure to the
filler neck overflow tube, reference figure B3. Pressur-
ize until the pressure release tab releases (blows out the
excess air pressure).
G. Open the pump manifold valve (upper valve). Refer-
ence Figure B2. This will allow the solution to enter
into the heating system (i.e. zone pumps, heat exchang-
ers and plumbing lines).
H. Slowly open the drain valve to allow the air to escape.
Reference Figure B2.
I. Close the Drain Valve.
J. Close the pump manifold valve.
K. Repeat steps B-J for all three zone pumps (i.e. Bedroom,
Bathroom, and Living Room).
L. Once all air had been bled from the system, be sure that
both the return manifold valve (lower), located on the
left side of the diesel burner and the pump manifold
valve (upper) are completely opened. Reference
Figure B2.
M. Once all air has been bled from the system, be sure to
connect and clamp the overflow tubing to the Aqua-
Hot’s Expansion tank.
NOTE:
Be sure to check that the drain valve is com-
pletely closed.
NOTE:
1. Depending on the plumbing lines diameter and total
length it may be necessary to repeat B-J several times
before any of the solution appears.
2. Be sure to close both the drain valve and the pump
manifold valve each time that the boiler tank is refilled
and pressurized.
3. Make sure that the Aqua-Hot’s boiler tank has a mini-
mum of 11 gallons of solution in it at all times while
bleeding the heating system. If the capacity should
drop below the 11 gallon minimum, air will enter back
into the heating system and the bleeding process will
need to be repeated.
NOTE:
The system may also be pressurized using a
Cooling System Tester. Reference Figure B4
