Selecting the Installation Location Basic Requirements Installing the unit in the following places may cause malfunctions. If installation in one of these locations is unavoidable, please consult the retailer from which you purchased the split air conditioner. Do not install the indoor or outdoor unit in a location exposed to strong heat sources, vapors, or flammable and/or explosive gasses.
Electrical Connection Requirements Safety Precautions You must follow electric safety regulations when installing the unit. Use a qualified electrical supply and circuit breaker that is properly grounded in accordance with the National Electrical Code (NEC) and all state and local codes and ordinances. Make sure that the power supply fulfills the requirements of the air conditioner. Avoid unstable power supplies and incorrect wiring that can lead to malfunctions.
Installing the Indoor Unit Step One: Choose the Installation Location Choose a suitable installation location according to the specifications for indoor and outdoor unit placement listed earlier in this document. Step Two: Install the Wall-mounting Frame Note: Use a stud finder to locate studs in order to prevent unnecessary damage to the wall. 1. Position the wall-mounting frame using a carpenter’s level, then mark the location of the screw holes on the wall. 2.
2. Open a piping hole in the wall with a diameter of ϕ55mm (ϕ2 5/32”) on the selected rear piping hole position. To ensure smooth drainage, slant the piping hole slightly downward towards the outdoor side at an angle of 5°-10°. Note: Take precautions to ensure that dust and other particles do not enter the open end of the outlet pipe. Step Four: Install the Outlet Pipe 1. The pipe can be routed in one of the following directions: right (1), rear right (2), rear left (3), or left (4). 2.
Step Five: Connect the Pipe of the Indoor Unit 1. Aim the pipe joint at the corresponding bell mouth. 2. Pre-tighten the union nut by hand. 3. Refer to the following table to adjust the torque force. Place the open-end wrench on the pipe joint and place the torque wrench on the union nut. Tighten the union nut with the torque wrench. 4. Wrap the indoor pipe and the joint of the connection pipe with an insulating pipe (not supplied), and then wrap that with tape.
2. Bind the joint with the provided tape. Note: Add an insulating pipe to the indoor drain hose in order to prevent condensation. Step Seven: Connect the Wiring of the Indoor Unit 1. Open the panel, remove the screw on the wiring cover, and then take off the cover.
2. Feed the power connection wire through the cable-cross hole at the back of the indoor unit and then pull it through the front side of the unit. 3. Remove the wire clip. Connect the power connection wire to the wiring terminal according to the color. Tighten the screw and then fix the power connection wire in place with the wire clip. 4. Replace the wiring cover and then tighten the screw. 5. Close the front panel.
Step Eight: Wrap the Pipes and Wires 1. Bind the connection pipe, power cord, and drain hose with the included pipe wrapping tape. Binding Tips: Be sure to keep the indoor power cord and the drain hose separate when you begin binding, and then add them to the binding bundle when you have enough length left aside. Bind all components evenly. The liquid pipe and the gas pipe should be bound separately at the end. Note: The power cord and control wire cannot be crossed or wound around each other.
Step Nine: Hang the Indoor Unit 1. 2. 3. 4. 5. Place the bound pipes and cords inside the wall pipe and pass them through the wall hole. Hang the indoor unit on the wall-mounting frame. Seal the gap between the pipes and the wall hole with an appropriate sealant. Fix the wall pipe in place. Check whether the indoor unit is installed firmly and sealed to the wall. Note: Do not bend the drain hose excessively in order to prevent blocking.
Installing the Outdoor Unit Step One: Install Support Structure for the Outdoor Unit 1. Select a suitable installation location following the guidelines specified in the “Selecting the Installation Location” section earlier in this document. 2. Follow all instructions provided by manufacturer for installing a ground pad, verifying it is properly leveled by using a carpenter’s level. 3. Secure the unit to the ground pad with concrete bolts, expansion screws, or other suitable anchors.
Step Two: Install the Drain Joint 1. Connect the outdoor drain joint into the hole on the chassis, as shown in the figure below. 2. Connect the drain hose onto the drain vent. Step Three: Secure the Outdoor Unit 1. Place the outdoor unit on the support structure. 2. Attach fasteners, which are not included with the outdoor unit, through the foot holes of the outdoor unit to secure it in place. Step Four: Connect Indoor and Outdoor Pipes 1.
2. Remove the screw cap of the valve and aim the pipe joint at the bell mouth of the pipe. 3. Pre-tighten the union nut by hand. 4. Use a torque wrench to tighten the union nut. Refer to the table below. Hex Nut Diameter (inches / mm) Φ15/64” / Φ6mm Φ3/8” / Φ9.
Step Five: Connect Outdoor Electric Wire 1. Remove the wire clip. Connect the power connection wire and the signal control wire to the wiring terminal according to the color. Secure these wires in place with screws. 2. Secure the power connection wire and the signal control wire in place with a wire clip. Note: After you tighten the screw, pull on the power cord gently to check whether the connection is firm. Never cut the power connection wire in an attempt to alter its length.
2. If the outdoor unit is placed higher than the hole in the wall, you must set a U-shaped curve in the outdoor segment of the pipe. This prevents rain or other outside moisture from running inside. 3. Secure the pipes to the wall using pipe hangers (not included). Vacuum Pumping 1. Remove the valve caps on the liquid valve and gas valve. Remove the nut of the refrigerant charging vent. 2. Connect one of the piezometer’s charging hoses to the refrigerant charging vent of the gas valve.
Leakage Detection 1. Using a leakage detector: Check for leaks with the leakage detector. 2. Using soapy water: If you do not have access to a leakage detector, use soapy water for leakage detection. Apply soapy water at the suspected source of the leak for three (3) minutes. If you see bubbles coming out of the suspected source of the leak, then a leak is present. Test Operation 23 Connect the unit to a power supply and press the ON / OFF button on the remote control to begin operation.
Configuration of the Connection Pipe The standard length of the connection pipe is 16.4 feet. The minimum length of the connection pipe is 10 feet. The maximum length of the connection pipe is 65 feet. If you extend the connection pipe, the unit will require additional refrigerant oil. If the length of the connection pipe is extended 32.8 feet beyond the standard length (16.4 feet), you must add 0.17 oz (5ml) of refrigerant oil for each additional 16.4 ft of connection pipe.
Pipe Expanding Method Note: Improper pipe expanding is the main cause of refrigerant leakage. Please expand the pipe in accordance with the following steps. 1. Cut the Pipe. Confirm the desired pipe length based on the distance between the indoor unit and the outdoor unit. Cut the pipe to the required length with a pipe cutter. 2. Remove the burrs. Use a shaper to remove the burrs from the pipe. Prevent the burrs from getting inside of the pipe. 3. Attach a suitable insulating pipe.
4. Attach the union nut. Remove the union nut on the indoor connection pipe and the outdoor valve. Install the union nut on the pipe. 5. Expand the port. Use an expander to increase the diameter of the port. Note: The “A” measurement varies according to the diameter. Refer to the table below. A (inches / mm) Outer Diameter (inches / mm) Φ1/4” / Φ6.mm - Φ6.35mm Max Min 3 /64” / 1.3mm 1 /64” / 0.7mm 1 /16” / 1.6mm 1 /32” / 1.0mm Φ1/2” / Φ12mm - Φ12.7mm 5 /64” / 1.8mm 1 /32” / 1.
Post Installation Checklist Items to be Checked Have the indoor and outdoor units been installed firmly? Have you performed the refrigerant leakage test? Is the pipeline sufficiently insulated? Does the water drain efficiently? Does the power supply match the electrical requirements on the rating label? Are the electric wiring and pipeline installed correctly? Is the unit securely grounded? Does the power cord meet the specifications noted on the rating label? Is the power supply cord properly rated for use
