4.1 CHANGING ACTUATOR ADAPTERS
The ECO 1
™
with actuator is factory set to fit a 3/4 in. brass manual anti-siphon
valve. To install the controller with actuator on a 1 in. manual anti-siphon valve
the 3/4 in. seat washer and adapter must be removed and replaced with the 1 in.
adapter and seat washer, which are included in this box.
1. Turn the actuator so that the seat washer and the 3/4 in. threaded adapter face up.
2. Using pliers, or a 5/18 in. wrench,
remove the seat washer screw by
turning counter clockwise
and pull off the 3/4 in. seat
washer assembly
(see Figure A).
3. Push the 3/4 in. threaded adapter
down towards the actuator to
ease the tension on the retainer
clip (see Figure B).
4. Next, place your thumb on one
side of the retainer clip and with
a pair of pliers grip the other
side of the retainer clip and pull
outwards, away from your thumb,
and upwards, removing it from
the base of the 3/4 in. threaded
adapter then, remove the adapter (see Figure C).
