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.
12.6 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.12.11a)
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 (refer to fig.12.11b).
When connect a lengthen drainpipe, apply protective tube to wrap its indoor parts for ensuring the lengthen part
connected tightly.
In case the drainpipe outlet is higher than pumping connective pipe of the main body, the drainpipe must be
arranged upwards vertically by using connective assembly of the water outlet for vertical bending, and the height
of the drainpipe shall set to the defrosting pan surface no more than 1000mm, otherwise, too much backflow
while shutdown would leads to overflow (refer to fig.12.12).
Base on the actual requirement to bend piping, and use connective assembly of water outlet in terminal box for
pipe layout.
Caution:
The joints in drain system must be sealed to avoid water leakage.
The height from floor to the end of drainpipe or the bottom of drain slot must more than 50 mm. Don’t immerse
the end of drainpipe or the bottom of drain slot into water. When drain condensate liquid to raceway, please bend
the drainpipe to a U-sharped hydroseal for avoiding stench transmitted by drainpipe to indoor.
Note:
All the pictures in this manual are for explanation purpose only. They may be slightly different from the air-conditioner you purchased
(depend on model).The actual shape shall prevail.
