Installation and Maintenance
(1) Take sufficient protective measures when installing the
outdoor unit.
(2) Make sure the support can withstand at least four times the
unit weight.
(3) The outdoor unit should be installed at least 1 3/16 inch
above the floor in order to install drain joint.(As show
n
in
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.
(1) After tightening the screw, pull the power cord slightly to
check if it is firm.
(2) Never cut the power connection wire to prolong or shorten
the distance.
(1) The through-wall height of
condensate
hose shouldn't be
higher than the outlet pipe hole of indoor unit.(As show
n
in
Fig.25)
(2) Slant the
condensate
hose slightly downwards. The
condensate
hose can't be curved, raised and fluctuant, etc.(As

screws.(As show
n
in Fig.23)
6. Neaten the Pipes
(1) The pipes should be placed along the wall, bent reasonably
and hidden
if
possibl
e
. 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
show
n
in Fig.24)
(2) Fix the power connection wire and power cord with wire clip.
(3) Fix the stopper on handle with screw.
