13.5 Install the Panel
Caution:
Never put the panel face down on floor or against the wall, or on bulgy objects.
Never crash or strike it.
(1) Remove the air inlet grill.
a. Slide two grid switches toward the middle at the same time, and then pull them up. (Refer to fig. 9)
b. Draw the grid up to an angle of about 45o, and remove it. (Refer to fig. 10)
(2) Remove the installation covers at the four corners.
Wrench off the bolts, loose the rope of the installation covers, and remove them. (Refer to fig. 11)
(3) Install the panel
a. Align the swing motor on the panel to the tubing joints of the body properly.
b. Fix hooks of the panel at swing motor and its opposite sides to the hooks of corresponding water
receiver. Then hang the other two panel hooks onto corresponding hangers of the body.
Cautions:
Do not coil the wiring of the swing motor into the seal sponge.
c. Adjust the four panel hook screws to keep the panel horizontal, and screw them up to the ceiling evenly.
d. Regulate the panel in the direction of the arrow slightly to fit the panel's center to the center of the
ceiling's opening. Guarantee that hooks of four corners are fixed well.
e. Keep fastening the screws under the panel hooks, until the thickness of the sponge between the body
and the panel's outlet has been reduced to about 4~6mm. The edge of the panel should contact with the
ceiling well.
If the gap between the panel and ceiling still exists after fastening the screws, the height of the indoor unit
should be modified again.
You can modify the height of the indoor unit through the openings on the panel's four corners; if the lift of the
indoor unit and the drainpipe is not influenced.
(4) Hang the air-in grid to the panel, and then connect the lead terminator of the swing motor and
that of the control box with corresponding terminators on the body respectively.
(5) Relocate the air-in grid in the procedure of reversed order.
(6) Relocate the installation cover.
a. Fasten the rope of installation cover on the bolt of the installation cover.
b. Press the installation cover into the panel slightly.
13.6 Connect the Drain Pipe
Install the drainpipe of the indoor unit
 The drainpipe can use PVC pipe (external diameter about 37～39mm, inner diameter is 32mm).
 Joint drainpipe connector to the end side of water pumping pipe, and fix drainpipe together with water
outflow pipe and thermal insulation tube by clasp of water outflow pipe (attached).
Caution: Don't use forcing strength to crack the water-pumping pipe.
 Water-pumping pipe and drainpipe from main body must be wrapped by insulation tube evenly, and
bound by tighten band for obstructing air getting in and coagulation.
 Prevent from water backflow into unit inside during shutdown, the drain pipe shall place down side and
drain water to outdoor (drain side), the gradient of the drain pipe should be higher than (1/100), without
salient and water remain.(Refer to Fig.6-1 a)
 When connecting drainpipe, don't drag the pipe that would pull the main unit. For this, please arrange
bearing points every 0.8 to 1.0 meter to avoid pipe be bended (See Fig.6-1 b).
