INSTALLATION INSTRUCTIONS
The length could be calculated from Fig.17:
Length=210+L(in general, L is half of the whole
length of the installation hook)
c. Please adjust the hexangular nuts on the four
installation hooks evenly, to ensure the balance
of the body.
Use the transparent hose filled with water to check
the lever of the main body from the four sides or
diagonal line direction, the lever indicator also
can check the lever from four sides of the main
body .(Refer to Fig.18)
If the drainpipe is awry, leakage will be caused
by the malfunction of the water-level switch.
Adjust the position to ensure the gaps between
the body and the four sides of ceiling are even.
The body's lower part should sink into the ceiling
for 10~12mm (Refer to Fig.17).
Locate the air conditioner firmly by wrenching the
nuts after having adjusted the body's position well.
New built houses and ceilings

ation paper board onto the air conditioner with bolts
