Step 4: Prepare refrigerant piping The refrigerant piping is inside an insulating sleeve attached to the back of the unit. You must prepare the piping before passing it through the hole in the wall. Refer to the Refrigerant Piping Connection section of this manual for detailed instructions on pipe faring and fare torque requirements, technique, etc. NOTE ON PIPING ANGLE Refrigerant piping can exit the indoor unit from two different angles: Left-hand side Right-hand side Refer to Fig. 4.4 for details.
Step 5: Connect drain hose PLUG THE UNUSED DRAIN HOLE By default, the drain hose is attached to the left, hand side of unit (when you re facing the back of the unit). To prevent leaks you must plug the excess space in the drain hole with the rubber plug. . 1. To ensure proper drainage, attach the drain hose on the same side that your refrigerant piping exits the unit. CORRECT 2. Attach drain hose extension (purchased separately) to the end of drain hose.
BEFORE PERFORMING ELECTRICAL WORK, READ THESE REGULATIONS 1. All wiring must comply with local and national electrical codes, and must be installed by a licensed electrician. 2. All electrical connections must be made according to the Electrical Connection Diagram located on the panels of the indoor and outdoor units. 3. If there is a serious safety issue with the power supply, stop work immediately.
Step 6: Connect indoor power wire TAKE NOTE OF FUSE SPECIFICATIONS The cable enables communication between the indoor and outdoor units. You must first choose the right cable size before preparing it for connection. The air conditioner s circuit board (PCB) is designed with a fuse to provide overcurrent protection. The specifcations of the fuse are printed on the circuit board, such as: T3.15A/250VAC, T5A/250VAC, etc.
NOTE ABOUT WIRING THE WIRING CONNECTION PROCESS MAY DIFFER SLIGHTLY BETWEEN UNITS Step 7: Wrap piping and cables Before passing the piping, drain hose, and the signal cable through the wall hole, you must bundle them together to protect them, insulate them, and save space. Indoor Unit When wrapping the bundle, keep the ends of the piping unwrapped. You need to access them to test for leaks at the end of the installation process (refer to Electrical Checks and Leak Checks section of this manual).
