In order to ensure that you have ample room to mount the indoor unit, the diagrams to the right Right rear side refrigerant pipe hole refrigerant pipe hole 2.6in/65mm with the following dimensions: 2.
Indoor Unit Installation 3. 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 insulating sleeve to reveal about 6 in (15 cm) of the refrigerant piping.
Indoor Unit Installation Make sure there are NO kinks or dents in the hose to ensure proper drainage. Step 5: Connect drain hose By default, the drain hose is attached to the left-hand side of unit (when you’re facing the back of the unit). However, it can also be attached to the right-hand side. 1. To ensure proper drainage, the drain hose must exit the unit on the same side as the refrigerant piping. 2. Fig. 3.6a to ensure a good seal and to prevent leaks. 3.
Indoor Unit Installation 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.

Press the "check switch" on the outdoor unit PCB board for 5 seconds until LED displays "CE". Approximately 5 to10 minutes after the switch is pressed, the "CE" will disappear when the wiring and piping are reassociated and the error is corrected.
Test Run Refrigerant Piping Connection 8 Before Test Run List of Checks to Perform Only perform test run after you have completed the following steps: No electrical leakage • Electrical Safety Checks the electrical system is safe and operating properly • Gas Leak Checks All electrical terminals properly covered not leaking Indoor and outdoor units are solidly installed pressure) valves are fully open All pipe connection points do not leak Test Run Instructions You should perform the Test Run for
Testing DOUBLE-CHECK PIPE CONNECTIONS During operation, the pressure of the refrigerant circuit will increase. This may reveal leaks that were not present during your initial leak check. Take time during the Test Run to double-check that all refrigerant pipe connection points do not have leaks. Refer to Gas Leak Check section for instructions. 5. After the Test Run is successfully complete, and Perform have PASSED, do the following: a. operating temperature. Manual control button b.
