4. OPENING THE SHUT-OFF VALVES

Ball valves are used for the shut-off valves on the outdoor unit. Each can be opened and closed by rotating
the tab 90 degrees.
Follow the procedure below to securely open the valves.
1. Remove the cap.
2. Slowly and securely turn the tab to the left
(counterclockwise) 90 degrees.
The valve is fully open when the tab has
been rotated 90 degrees (when it contacts
the stopper). Do not forcefully attempt to
turn the tab past this point.
Be sure to open the shut-off valve all the way.
3. Reattach and tighten the cap.
