Indoor Unit Installation Installation Instructions – Indoor unit PRIOR TO INSTALLATION Before installing the indoor unit, refer to the label on the product box to make sure that the model number of the indoor unit matches the model number of the outdoor unit. Step 1: Select installation location Before installing the indoor unit, you must choose an appropriate location. The following are standards that will help you choose an appropriate location for the unit.

Determine the location of the wall hole based on the position of the mounting plate. Refer to Mounting Plate Dimensions. 2. Using a 2.5in (65mm) or 3.54in (90mm) (depending on models) core drill, drill a hole in the wall.
Step 4: Prepare refrigerant piping and Features 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. 1. Based on the position of the wall hole relative to the mounting plate, choose the side from which the piping will exit the unit. 2. If the wall hole is behind the unit, keep the knock-out panel in place.
BEFORE PERFORMING ANY ELECTRICAL WORK, READ THESE REGULATIONS 1. All wiring must comply with local and national electrical codes and regulations 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.
1. Open front panel of the indoor unit. 2. Using a screwdriver, open the wire box cover on the right side of the unit. This will reveal the terminal block. NOTE ABOUT WIRING THE WIRING CONNECTION PROCESS MAY DIFFER SLIGHTLY BETWEEN UNITS AND REGIONS. Step 7: Wrappiping and cables Before passing the piping, drain hose, and the signal cable through the wall hole, you must bundle them together to save space, protect them, and insulate them (Not applicable in North America). 1.
Step 8: Mount indoor unit If you installed new connective piping to the outdoor unit, do the following: 1. If you have already passed the refrigerant 2. 3. 4. 5. 6. 7. piping through the hole in the wall, proceed to Step 4. Otherwise, double-check that the ends of the refrigerant pipes are sealed to prevent dirt or foreign materials from entering the pipes. Slowly pass the wrapped bundle of refrigerant pipes, drain hose, and signal wire through the hole in the wall.

Step 2: Install drain joint (Heat pump unit only) Before bolting the outdoor unit in place, you must install the drain joint at the bottom of the unit. Note that there are two different types of drain joints depending on the type of outdoor unit. If the drain joint comes with a rubber seal (see Fig. A ), do the following: 1. Fit the rubber seal on the end of the drain joint that will connect to the outdoor unit. 2. pan of the unit. 3.

Step 4: Connect signal and power cables The outside unit’s terminal block is protected by an electrical wiring cover on the side of the unit. A comprehensive wiring diagram is printed on the inside of the wiring cover. WARNING BEFORE PERFORMING ANY ELECTRICAL OR WIRING WORK, TURN OFF THE MAIN POWER TO THE SYSTEM. 1.
Refrigerant Piping Connection When connecting refrigerant piping, do not let substances or gases other than the specified refrigerant enter the unit. The presence of other gases or substances will lower the unit’s capacity, and can cause abnormally high pressure in the refrigeration cycle. This can cause explosion and injury. Note on Pipe Length The length of refrigerant piping will affect the performance and energy efficiency of the unit. Nominal efficiency is tested on units with a pipe length of 16.
Step 2: Remove burrs Burrs can affect the air-tight seal of refrigerant piping connection. They must be completely removed. 1. Hold the pipe at a downward angle to prevent burrs from falling into the pipe. 2. Using a reamer or deburring tool, remove all burrs from the cut section of the pipe.

2. Tighten the flare nut as tightly as possible by hand. 3. Using a spanner, grip the nut on the unit tubing. 4. While firmly gripping the nut on the unit tubing, use a torque wrench to tighten the flare nut according to the torque values in the Torque Requirements table below. Loosen the flaring nut slightly, then tighten again. TORQUE REQUIREMENTS Outer Diameter of Pipe (in/mm) Tightening Torque (lb•ft/N•cm) Add.

Air Evacuation If there is a change in system pressure, refer to Gas Leak Check section for information Air and foreign matter in the refrigerant circuit can on how to check for leaks. If there is no change in system pressure, unscrew the cap cause abnormal rises in pressure, which can damage the air conditioner, reduce its efficiency, and cause 9. from the packed valve (high pressure valve). Insert hexagonal wrench into the packed valve injury.
Note on Adding Refrigerant Some systems require additional charging depending on pipe lengths. The standard pipe length varies according to local regulations. For example, in North America, the standard pipe length is 25 ft (7.5m). In other areas, the standard pipe length is 16 ft (5m). The refrigerant should be charged from the service port on the outdoor unit’s low pressure valve.
Electrical and Gas Leak Checks Before Test Run Only perform test run after you have completed the following steps: Electrical Safety Checks – Confirm that the unit’s electrical system is safe and operating properly Gas Leak Checks – Check all flare nut connections and confirm that the system is not leaking Confirm that gas and liquid (high and low pressure) valves are fully open Electrical Safety Checks After installation, confirm that all electrical wiring is installed in accordance with local and national reg
Test Run Test Run Instructions You should perform the Test Run for at least 30 minutes. 1. Connect power to the unit. 2. Press the ON/OFF button on the remote controller to turn it on. 3. Press the MODE button to scroll through the following functions, one at a time: COOL – Select lowest possible temperature HEAT – Select highest possible temperature 4.
