Fig.18)
(4) For the unit with cooling capacity of 2300W~5000W,
six expansion screws are needed; for the unit with cooling
capacity of 6000W~8000W, eight expansion screws are
needed; for the unit with cooling capacity of
10000W~16000W, 10 expansion screws are needed.

6. Neaten the Pipes
(1) The pipes should be placed along the wall, bent reasonably
and hidden if possible. Min. semidiameter of bending the pipe
is 3 15/16inch.
(2) If the outdoor unit is higher than the wall hole, you must set
a U-shaped curve in the pipe before pipe goes into the
room, in order to prevent rain from getting into the room.(As
shown in Fig.24)
