B.Drainage test
● Check whether the drainpipe is unhindered.
● New built house should have this test done before paving the ceiling.
● For VRF system please do drainage test after finishing all installations, wiring and piping included, and doing ITEST (Installation test )
sucessfully:
1) Refer to chart 18.
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 long of 1 min 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, turn off the power, and reset the test cover to its original position.
● Imposition at all times during operation to avoid leakage.

● Use the correct screwdriver for tightening the terminal screws.If the blade of screwdriver is too small, the head of the screw might be damaged, and
the screw will not be properly tightened.
● If the terminal screws are tightened too hard, screws might be damage.
● Refer to the table below for the tightening torque of the terminal screws.
