3. Install the Sleeve.
Attach the sleeve to the inside wall using 3 screws arranging the flange so that the marking

4. Install the Terminal.
Check that the terminal seal is in place. For weatherboard walls, add the second seal next to the
terminal seal to compensate for weather board angle. Adjust the second seal to make sure "Top"
marking of the second seal is located at the top or "Ʌ" marking is aligned with "V" marking on the
terminal.
From the outside insert the terminal into the sleeve with the marking "TOP" at the top. The left
hand side locking tie should be marked "LEFT".
