Please note: the existing ball valve must be in
good working order. It must open and close
smoothly, with minimal effort, and it must close
fully, shutting off the water completely. The
Bulldog Valve Robot is not able to correct
mechanical issues of the ball valve.
Your Valve Controller connects to the internet via
a YoLink Hub or SpeakerHub, and it does not
directly connect to your WiFi or local network. In
order for remote access to the device from the
app, and for full-functionality, a YoLink hub is
required. This guide assumes the YoLink app
has been installed on your phone, and a YoLink
Hub or SpeakerHub is installed and online.
If installing the Valve Controller and Bulldog
Valve Robot outdoors, please refer to the
environmental range specifications found on the
Valve Controller product support page. While
these devices can be installed outdoors, it
should be protected from rain and direct sunlight
by an enclosure or overhead cover, such as a
rain hood.

Preparing for installation:
Determine where you will mount the valve
controller. The Valve Controller 1 was designed
to be wall-mounted, at an indoor or outdoor
location.
If installing your Valve Controller 1 and/or valve
device at an outdoor location, please first refer to
the environmental range specifications, found on
the Valve Controller 1 product support page of
our website. Also, while the Valve Controller 1,
the Bulldog Valve Controller and our motorized
valves are rated for outdoor use, to ensure years
of dependable operation, provide protection from
rain and direct sunlight with overhead cover, in
the form of an enclosure or rain hood.�
Do not install your valve controller or valve
device at a location where it will be submerged
in water.
With the use of optional extension cables, the
valve controller can be installed remotely from
the Bulldog or motorized valve. In some cases
this may allow placing the controller at a more
convenient or more accessible location (for
battery replacement, etc.). The location of the
valve controller must be within the limits of the
cables. If in doubt, connect all applicable cables
between the controller and the valve device and
choose an appropriate location for the controller.
(Extension cables can be purchased on our
website.)

Install the Valve Controller 1,
Continued
I
Determine how you will mount the valve
controller to the wall, and ensure you have the
appropriate mounting hardware (screws,
anchors, etc.) for the wall surface.
Install the Valve Controller 1:
1. Holding the valve controller at the desired
location, and using a marker or pencil, transfer
the valve controller’s top mounting hole location
to the wall surface.
2. If using wall anchors, install one at the top
mounting hole location, per the manufacturer’s
instructions (drill a pilot hole first, etc.)
3. Insert a screw in the top mounting hole
location, but do not screw it flush with the wall;
leave space on the end of the screw for the valve
controller.
4. Hang the valve controller on this screw, and it
should be level on the wall. Optionally, you can
verify the valve controller is level with a level tool
at this time.
5. Tighten the screw, and confirm the valve
controller is secured to the wall surface.
To install a motorized valve, go to page 28. To
install a Bulldog Valve Robot, proceed to the next
page.

1. Select the appropriate bracket for your
application. The appropriate bracket fits over the
ball valve (where it is connected to the pipe) and
can subsequently be tightened securely to the
ball valve. If the bracket does not fit over the ball
valve, or seems to be too loose, try the other
bracket.
2. Loosen the two screws on the bracket, to
allow for separating it into two pieces, as shown.

3. Place the upper bracket and lower bracket on
the valve, as shown, and loosely tighten the
screws.
Important! The bracket must be mounted to the
ball valve, not to the pipe. The ball valve should
have at least one side shaped like a nut or bolt
head. The brackets will not tighten to pipe or to a
round portion of the ball valve.

4. Position the bracket so that it is aligned with
the pivot point of the ball valve, by visualizing a
line between the tab slot and the pivot point, as
shown.
5. Remove the screw from the tab slot, then
attach the Valve Robot to the bracket.
