1. The ECO is mounted on the lower left
outlet water pipe. (See figure C)
a. Remove one lead connecting to ECO
terminal, it does not matter which one is
disconnected.
b. Attach 1/4" quick connect terminal end of
linear spill switch cable to now exposed
terminal of the ECO.
c. Remove the eyelet ended terminal from
the other spill switch cable. Affix the push on
male spade connector, which is provided with
the AQ1, to this spill switch cable.
d. Connect this male spade connector to the
removed lead wire from step 3.a.
The linear spill switch should be attached to the upper
right-hand side on the draft hood diverter (see figure D),
on the Model 425HN and 125HX the linear spill switch
should be attached to the upper left-hand side of the
draft hood diverter. There are two holes provided for
attachment on this diverter and only the front most hole
should need to be used. With the provided #12 self
tapping sheet metal screw securely mount the spill
switch bracket to the diverter. For ease of access
position it so the reset button faces outward and then
bend the bracket so the switch can stand vertically.
The copper capillary sensing tube should then be di-
rected to the opposite end of the draft hood diverter, by
laying it in front of the 5" diameter vent pipe opening, and
down the other side of the draft hood diverter.
DISCONNECT EITHER WIRE FROM ECO
TERMINALS ON HOT WATER PIPE. PUSH ON
