Indoor Unit Installation 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 flaring and flare torque requirements, technique, etc. 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.
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. Wrap the connection point firmly with Teflon tape to ensure a good seal and to prevent leaks. Fig. 4.
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. 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.
Indoor Unit Installation Step 6: Connect signal cable CHOOSE THE APPROPRIATE CABLE SIZE The size of the power supply cable, signal cable, fuse, and switch needed is determined by the maximum unit current. The maximum unit current is indicated on the nameplate located on the side panel of the unit. Refer to this nameplate to choose the right cable, fuse, or switch. NOTE: In North America, please choose the right cable size according to the Minimum Circuit Ampacity indicated on the nameplate of the unit. 4.
Indoor Unit Installation Step 8: Mount indoor unit Step 7: Wrap piping Before passing the piping and drain hose through the wall hole, you must bundle them together to protect them, insulate them, and save space. 1. Bundle the drain hose and refrigerant pipes according to Fig. 4.8. Indoor Unit Space behind unit Refrigerant piping Insulation tape Drain hose Fig. 4.8 DRAIN HOSE MUST BE ON BOTTOM Make sure that the drain hose is at the bottom of the bundle.
Indoor Unit Installation If refrigerant piping is already embedded in the wall, do the following: 3. Connect drain hose and refrigerant piping (refer to Refrigerant Piping Connection section of this manual for instructions). 1. Hook the top of the indoor unit on the upper hook of the mounting plate. 4. Keep piping connections exposed to perform the leak test (refer to Electrical Checks and Leak Checks section of this manual). 2.

The following standards will help you choose an appropriate location.
Outdoor Unit Installation SPECIAL CONSIDERATIONS FOR EXTREME WEATHER If the unit is exposed to heavy wind: Install unit so that air outlet fan is at a 90° angle to the direction of the wind. If needed, build a barrier in front of the unit to protect it from extremely heavy winds. Ensure the wind barrier does not block necessary airflow. See Fig. 5.2 and Fig. 5.3 below. If the drain joint comes with a rubber seal (see Fig. 5.4 - A), do the following: 1.
Outdoor Unit Installation A Air Inlet D H Air Inlet B Air Outlet W Fig. 5.5 Step 3: Anchor outdoor unit UNIT MOUNTING DIMENSIONS The outdoor unit can be anchored to the ground or to a wall-mounted bracket with bolts (M10). Prepare the installation base of the unit according to the dimensions below. The following is a list of different outdoor unit sizes and the distance between their mounting feet. Prepare the installation base of the unit according to the dimensions below.
Outdoor Unit Installation If you will install the unit on a wall-mounted bracket, do the following: BEFORE PERFORMING ELECTRICAL WORK, READ THESE REGULATIONS 1. All wiring must comply with local and Before installing a wall-mounted unit, make sure that the wall is made of solid brick, concrete, or of similarly strong material. The wall must be able to support at least FOUR times the weight of the unit. 1. Mark the position of bracket holes based on dimensions in the Unit Mounting Dimensions chart. 2.

66 Refrigerant Piping Connection When connecting the 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 could cause an explosion and/or injury. NOTE ON PIPE LENGTH The length of refrigerant piping will affect the performance and energy efficiency of the unit.
Refrigerant Piping Connection Flare nut DO NOT DEFORM PIPE WHILE CUTTING Be extra careful not to damage, dent, or deform the pipe while cutting. This will drastically reduce the heating efficiency of the unit. Copper pipe Step 2: Remove burrs Fig. 6.3 Burrs can affect the air-tight seal of refrigerant piping connection. They must be completely removed. 4. Remove PVC tape from ends of pipe when ready to perform flaring work. 1. Hold the pipe at a downward angle to prevent burrs from falling into the pipe.
Refrigerant Piping Connection Step 3: Flare pipe ends continued 6. Place flaring tool onto the form. 7. Turn the handle of the flaring tool clockwise until the pipe is fully flared. Radius ≥4 in (10 cm) 8. Remove the flaring tool and flare form, then inspect the end of the pipe for cracks and even flaring. Fig. 6.6 Step 4: Connect pipes When connecting refrigerant pipes, be careful not to use excessive torque or to deform the piping in any way.
Refrigerant Piping Connection Instructions for Connecting Piping to Indoor Unit 1. Align the center of the two pipes that you will connect. See Fig. 6.7. 2. Tighten the flare nut as tightly as possible by hand. 3. Using an adjustable wrench, 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. Loosen the flaring nut slightly, then tighten again.
7 Refrigerant Piping Connection Air Evacuation MC MC Preparations and Precautions Air and foreign matter in the refrigerant circuit can cause abnormal rises in pressure, which can damage the air conditioner, reduce its efficiency, and cause injury. Use a vacuum pump and manifold gauge to evacuate the refrigerant circuit, removing any non-condensable gas and moisture from the system. Evacuation should be performed upon initial installation and when unit is relocated.
Air Evacuation 3. Open the low-pressure side of the manifold gauge. Keep the high-pressure side closed. 4. Turn on the vacuum pump to evacuate the system. Flare nut 5. Run the vacuum for at least 15 minutes, or until the Compound Meter reads -76 cmHG (-105 Pa). Valve stem 6. Close the low-pressure side of the manifold gauge, and turn off the vacuum pump. Cap 7. Wait for 5 minutes, then check that there has been no change in system pressure. Fig. 7.2 Valve body 8.
88 Refrigerant Piping Connection Electrical andand GasGas LeakLeak Checks Electrical Checks Gas Leak Checks Electrical Safety Checks After installation, confirm that all electrical wiring is installed in accordance with local and national regulations, and according to the Installation Manual. BEFORE TEST RUN Check Grounding Work Measure grounding resistance by visual detection and with grounding resistance tester. Grounding resistance must be less than 4.
Test Run Refrigerant Piping Connection 9 Before Test Run Only perform test run after you have completed the following steps: List of Checks to Perform • Electrical Safety Checks – Confirm that the electrical system is safe and operating properly No electrical leakage • Gas Leak Checks – Check all flare nut connections and confirm that the system is not leaking Unit is properly grounded • Confirm that gas and liquid (high and low pressure) valves are fully open All electrical terminals properly covered
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 you confirm all check points in List of Checks to Perform have PASSED, do the following: a.
