Installing the Expansion Tank:
Select a mounting location that allows for easy access
and clear visibility whenever the particular storage bay
door is open.
NOTE:
The top of the expansion tank should always be
mounted at least 4 inches higher than the highest point
on the Aqua-Hot’s boiler tank. Reference Figure 11.
1.
Mount the expansion tank as illustrated in Figure 11.
2.
Connect and clamp the overflow tubing from the
Figure 11
expansion tank to the Aqua-Hot’s expansion tank con-
nection. Reference Figure 11.
NOTE:
Avoid any dips and bends in the overflow tubing from
the Aqua-Hot to the expansion tank as air can become
trapped in these dips and bends, preventing the expan-
sion of the heating solution from properly depositing
in the expansion tank.
3.
Drill a hole in the bay floor and connect (secure with a
clamp) a long enough piece of overflow tubing so that
it can be connected to the top of the expansion tank
and extend through the bay floor.
