 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.6-2).
 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.
a
Drainage test
 Check whether the drainpipe is unhindered
 New built house should have this test done before paving the ceiling.
1. Remove the test cover, and stow water of about 2000ml to the water receiver through the stow tube.
2. Turn on the power, and operate the air conditioner under the "COOLING" mode. Listen to the sound of
the drain pump. Check whether the water is discharged well (a lag of 1min is allowed before discharging,
according to the length of the drain pipe), and check whether water leaks from the joints.
Cautions: If there is any malfunction, please resolve it immediately.
3. Stop the air conditioner for three minutes, check if everything is ok. If the drain hose is located
unreasonable, water overflow will cause the Alarm indicator lamp flashing (For both cooling and heating
type or cooling only type), even the water leak out from the water receiver.
4. Check the drain pump whether drain water immediately when alarm sound for the high water lever. If
