4.2 Water discharge test
1.Before the test, make sure that the water discharge pipeline is smooth, and check that each connection is
sealed properly.
2.Conduct the water discharge test in the new room before the ceiling is paved.
• Use the water injection pipe to fill the drain pan with about 500ml of water through the drain pan outlet (high
side) or through the air outlet (if the air outlet duct is not installed).
• Connect the power supply, and set the air conditioner to operate in the cool mode. Check that the water
discharge piping outlet discharges water properly (based on the length of the pipe, the discharge may occur at
a delay of 1 minute or so), and check for water leakages at each joint. The water injection pipe is marked as
shown in the following figure.
4.3 Installation of water discharge piping of ODU
Put the seal ring on the water outlet joint, insert it from the bottom of the ODU into the hole of the chassis and
rotate it 90 degrees to make it fit firmly. Connect the water discharge piping (to be purchased by the customer)
to the water outlet joint to discharge condensation water from the ODU during heating.
