CAUTION
To ensure the proper installation of the drain pump kit, please take note the following consideration when installing the indoor unit.
• Be sure that the suction side or drain socket side of the indoor unit is not at higher side of unit. Otherwise, the fl oat switch may
malfunction, causing water leakage or other failure.
3. INSTALLATION PROCEDURE
CAUTION
• Do not hold the drain pump kit by the drain socket when installing it to the indoor unit. Doing so may apply excessive force to the root
of the socket, resulting in water leakage.
• Do not give an excessive load up and down, when pulling and inserting the drain plug.
• Be sure to turn OFF the power to the indoor unit before starting the procedure below.
1. Assemble two hanging brackets (included) to the drain pump kit using mounting screw (included).
2. Pre-tighten mounting screw (included) at four prepared holes at unit side panel.
3. Mount the drain pump kit to the four pre-tightened screws at unit side panel, then tighten all the screws to fi x the drain pump kit to side panel.
