If mounting the unit on a concrete wall, use anchor bolts. • Mount the installation plate horizontally by aligning the centerline using a level. Installation Plate Chassis Hook Type "A" screw 2. Measure the wall and mark the centerline.
Flaring Work and Connection of Piping Flaring Work and Connection of Piping Flaring work Main cause for gas leakage is due to defect in flaring work. Carry out correct flaring work in the following procedure. Cut the pipes and the cable. 1. Use the piping kit accessory or the pipes purchased locally. 2. Measure the distance between the indoor and the outdoor unit. Copper pipe Slanted Uneven Rough 90° 3. Cut the pipes a little longer than measured distance. 4. Cut the cable 1.5m (5.
Flaring Work and Connection of Piping Check 1. Compare the flared work with the figure by. Smooth all round Inside is shiny without scratches 2. If a flared section is defective, cut it off and do flaring work again. = Improper flaring = Even length all round Inclined Surface Cracked Uneven damaged thickness Connecting the Piping Indoor 1. Prepare the indoor unit's piping and drain hose for installation through the wall. 2.
Flaring Work and Connection of Piping 4. Indoor unit installation Hook the indoor unit onto the upper portion of the installation plate.(Engage the two hooks of the rear top of the indoor unit with the upper edge of the installation plate.) Ensure that the hooks are properly seated on the installation plate by moving it left and right. Connecting cable Drain hose Press the lower left and right sides of the unit against the installation plate until the hooks engage into their slots(clicking sound).
Flaring Work and Connection of Piping For left rear piping 1. Route the indoor tubing and the drain hose to the required piping hole position. 1 2 Connecting cable 2. Insert the piping, drain hose, and the connecting cable into the piping hole. 3. Insert the connecting cable into the indoor unit. • Don't connect the cable to the indoor unit. • Make a small loop with the cable for easy connection later. Drain pipe 4. Tape the drain hose and the connecting cables. 5.
Flaring Work and Connection of Piping Wrap the insulation material around the connecting portion. 1. Overlap the connection pipe heat insulation and the indoor unit pipe heat insulation material. Bind them together with vinyl tape so that there may be no gap. 2. Wrap the area which accommodates the rear piping housing section with vinyl tape. Plastic bands Insulation material Indoor unit piping Connection pipe Vinyl tape (wide) Wrap with vinyl tape Pipe Vinyl tape(narrow) Connecting cable 3.
Flaring Work and Connection of Piping Installation Information. For left piping. Follow the instruction below. Good case • Press on the upper side of clamp and unfold the tubing to downward slowly. Bad case • Following bending type from right to left may cause damage to the tubing.
Flaring Work and Connection of Piping Outdoor Align the center of the pipings and sufficiently tighten the flare nut by hand. Finally, tighten the flare nut with torque wrench until the wrench clicks. • When tightening the flare nut with torque wrench, ensure the direction for tightening follows the arrow on the wrench.

Connecting the Cable between Indoor Unit and Outdoor Unit Connecting the Cable between Indoor Unit and Outdoor Unit Connect the cable to the Indoor unit. Connect the cable to the indoor unit by connecting the wires to the terminals on the control board individually according to the outdoor unit connection. (Ensure that the color of the wires of the outdoor unit and the terminal No. are the same as those of the indoor unit.) The earth wire should be longer than the common wires.
Connecting the Cable between Indoor Unit and Outdoor Unit Connect the cable to the Outdoor unit. 1. Remove the cover control from the unit by loosening the screw. Connect the wires to the terminals on the control board individually as the following. Outdoor unit Terminal block Over 5mm 2. Secure the cable into the control board with the strain relief clamp. Holder for power supply cord 3. Refix the cover control to the original position with the screw.
Connecting the Cable between Indoor Unit and Outdoor Unit Connection method of the connecting cable(Example) (1) Remove two-caps on the conduit panel. (2) Make a hole appropriate for the passage of connection cable through on cap by tool. (for low voltage line) (3) Pass the connecting cable through the hole. (4) Properly connect the cable on the terminal block.
Connecting the Cable between Indoor Unit and Outdoor Unit CAUTION! Provide a circuit breaker between the power source and the outdoor unit as shown below. Size breaker per the Maximum Fuse or Circuit Breaker (MOC) rating on the unit rating plate. Main power source Air Conditioner Circuit Breaker Use a circuit breaker or time delay fuse. Model Power source 24k 36k 1ø,230/208V 1ø,230/208V Connect the cable to the indoor unit 1.
Checking the Drainage, Forming the Pipings and Long Pipe Setting Checking the Drainage, Forming the Pipings and Long Pipe Setting Checking the drainage To check the drainage. 1. Pour a glass of water on the evaporator. 2. Ensure the water flows through the drain hose of the indoor unit without any leakage and goes out the drain exit. Drain piping 1. The drain hose should point downward for easy drain flow. Downward slope 2. Examples of incorrect drain piping.
Checking the Drainage, Forming the Pipings and Long Pipe Setting Forming the piping Form the piping by wrapping the connecting portion of the indoor unit with insulation material and secure it with two kinds of vinyl tape. • If you want to connect an additional drain hose, the end of the drain outlet should be routed above the ground. Secure the drain hose appropriately. Seal a small opening around the pipings with gum type sealer.
Air Purging and Evacuation Air Purging and Evacuation Air and moisture remaining in the refrigerant system have undesirable effects as indicated below. 1. Pressure in the system rises. 2. Operating current rises. 3. Cooling(or heating) efficiency drops. 4. Moisture in the refrigerant circuit may freeze and block capillary tubing. 5. Water may lead to corrosion of parts in the refrigeration system.
Air Purging and Evacuation Evacuation 1. Connect the charge hose end described in the preceding steps to the vacuum pump to evacuate the tubing and indoor unit. Confirm the "Lo" knob of the manifold valve is open. Then, run the vacuum pump. The operation time for evacuation varies with tubing length and capacity of the pump. The following table shows the time required for evacuation.
Charging Charging ■ Each outdoor unit is factory charged (nameplate charge) for the evaporator as well as a 7.5m(25ft) line set for each indoor line. Any time total line set is used either shorter or longer then the nominal 22.5m(75ft: for tri-zone) line set length the refrigerant charge has to be adjusted. ■ Whether the line set is made shorter or longer you must adjust the charge based on how many ft of tubing are either added or removed based on 20g(0.22oz) of R-410A per meter(foot).
Test Running Test Running 1. Check that all tubing and wiring have been properly connected. 2. Check that the gas and liquid side service valves are fully open. Prepare remote control Remove the battery cover by pulling it according to the arrow direction. Insert new batteries making sure that the (+) and (–) of battery are installed correctly. Reattach the cover by pushing it back into position. Bolt : • Use 2 AAA(1.5volt) batteries. Do not use rechargeable batteries.
