Flaring Work and Connection of Piping ENGLISH Flaring Work and Connection of Piping Flaring work Main cause of gas leakage is defect in flaring work. Carry out correct flaring work in the following procedure. Copper tube Slanted Uneven Rough 90 1) Cut the pipes and the cable. ■ Use the accessory piping kit or the pipes purchased locally. ■ Measure the distance between the indoor and the outdoor unit. ■ Cut the pipes a little longer than measured distance. ■ Cut the cable 1.5m(4.
Flaring Work and Connection of Piping Connection of piping - Outdoor Align the center of the piping and sufficiently tighten the flare nut by hand. Connecting pipe order 1) A~D-UNIT gas side pipe 2) A~D-UNIT liquid side pipe (Only Indoor Units 18 kBtu/h class ) 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 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 ground wire should be longer than the common wires. The circuit diagram is not subject to change without notice.
Connecting the Cable between Indoor Unit and Outdoor Unit Connect the cable to the Outdoor unit. 1. Remove the control cover from the unit by loosening the screw. Connect the wires to the terminals on the control board individually as the following. Outdoor unit Cover control 2. Secure the cable onto the control board with the Terminal holder (clamper). block Screw 3. Re-attach the cover control to the original position using the screws.
Connecting the Cable between Indoor Unit and Outdoor Unit (1) Remove the side panel and knockouts of conduit panel. (for low voltage line) (2) Pull out connection cable through conduit. (3) After conduit to the panel, fix nut to the opposite side of panel. (4) Pass the connection cabel through the hole. (5) Properly connect the cable on the terminal block.
Checking the Drainage, Insulating the Pipe and Special Piping Applications Checking the Drainage, Insulating the Pipe and Special Piping Applications Checking the drainage 1. Remove the Air Filter. 2. Check the drainage. • Spray one or two glasses of water upon the evaporator. • Ensure that water flows drain hose of indoor unit without any leakage. ❈ The figure can be changed according to model.
Long Pipe Setting ENGLISH Long Pipe Setting 1. Open the top cover of outdoor unit. 2. Select one of the two selectable modes as follows. 3. Set the Zone as shown in Fig. 4. Close the top cover and check whether the product works normally. WARNING: Do not open the top cover or Set the pipe length when operating the product.
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 ENGLISH 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. [Each Room] The vacuum pump must be operated less than 0.8torr of the gage pressure. Indoor unit Outdoor unit 2.
Charging Charging n If installed total piping length is more than standard total length, additional refrigerant charging is necessary. Below standard total piping length, additional refrigerant charging is not required.
