12.1.3.5 Checking the Drainage
12.1.3.5.1 Horizontal Installation Only
After wiring and drain piping are completed, use the following procedure to check that the water will drain smoothly.
For this, prepare a bucket and wiping cloth to catch and wipe up spilled water.
(1) Connect power to the power terminal board (L/1, N/2 terminals) inside the electrical component box.
(2) Remove the tube cover and slowly pour about 1,200 cc of water through the opening into the drain pan to check
drainage.
(3) Short the check pin (CHK) (6P : 1-4) on the indoor unit control PCB and operate the drain pump. Check the water
flow through the transparent upper drain port and see if there is any leakage.
* If the check pin (CHK) (6P : 1-4) is shorted, the fan starts rotating at high speed and could cause injury.
(4) When the drainage check is complete, open the check pin (CHK) (6P : 1-4) and remount the insulator and the
cap onto the drain inspection port.
12.1.3.6 Connecting Duct to Air Intake Port Side
