• Before doing repair work, please read the " SAFETY PRECA UTIONS" carefully and fully understand them. • The precautionary items here are divided into " W ar ning" and " Caution" items.
W arning If refrigerant gas blows off during the work, do not touch the refrigerant gas as it may cause frostbite . If refrigerant gas leaks during the wor k, v entilate the room. If refrigerant gas catches fire, harmful gas may be generated. Do not mix any gas other than the specified refrigerant gas in the refrigerating cycle.

15 3-4. Removing and Installing the Grille Basically , these models can be installed and wired with- out removing the grille. If access to any internal part is needed, follow the steps as given below .
16 3-5. Shape the Indoor Side T ubing (1) Arrangement of tubing by direction a) Right or left tubing Cut out the corner of the right/left frame with a hacksaw or the like. (Figs. 20 and 21) b) Right-rear or left-rear tubing In this case, the corner of the frame need not be cut.
17 3-7. Wire Size and Length Regulations on wiring diameter differ from locality to locality . For field wiring requirements, please refer to your local elec - trical codes. Carefully observe these regulations when carrying out the installation. Refer to the wiring system diagram (Fig.
18 3-8. Wiring Instructions for Inter-unit Connections (1) Insert the inter-unit wiring (according to local codes) into the through-the-wall PVC pipe. Run the wiring toward the indoor side allowing approx. 10" (25 cm) to extend from the wall face.
19 When connecting each power wire to the corresponding terminal, follow the instructions “How to connect wiring to the terminal” and fasten the wire securely tight with the fixing screw of the terminal plate.
20 3-9. Mounting (1) T o install the indoor unit, mount the indoor unit onto the 3 tabs on the upper part of the rear plate. (2) Hold down the air discharge outlet and press the lower part of the indoor unit until it clicks to securely fasten to the 2 tabs on the lower part of the rear plate.
21 Hole in wall Bent part Narrow tube Wide tube Rear panel Fig. 38 Drain cap Drain hose Clamp Fig. 39 Left-side tubing (1) Lead the tubing and drain hose through the wall, allowing sufficient length for connection. Then bend the tubing using a tube bender to make the attach- ment.
22 T o unmount indoor unit Press the 2 marks on the lower part of the indoor unit and unlatch the tabs. Then lift the indoor unit and unmount. (Fig.
23 4. How to Install the Outdoor Unit First refer to Section 2. Installation Site Selection. 4-1. Wiring Instructions for the Outdoor Unit Regulations on wire size differ from locality to locality . For field wiring requirements, please refer to your local elec- trical codes.
24 5. Refrigerant T ubing 5-1. Use of the Flaring Method Many of the conventional split system air conditioners employ the flaring method to connect refrigerant tubes which run between indoor and outdoor units. In this method, the copper tubes are flared at each end and connected with flare nuts.
25 5-4. Connecting T ubing between Indoor and Outdoor Units a) T ightly connect the indoor side refrigerant tubing exten- ded from the wall with the outdoor side tubing.
26 6. Air Purging Air and moisture remaining in the refrigerant system have undesirable effects as indicated below . Therefore, they must be purged completely .
27 (5) With the vacuum pump still running, close the “Lo” knob of the manifold valve. Then stop the vacuum pump. (6) With the hex wrench, turn the valve stem on the nar- row tube service valve counter-clockwise by 90 degrees (1/4 turn) for 10 seconds, and then turn the stem clockwise to close it again.
28 How to T est Run the Air Conditioner After turning on the power of the air conditioner , use the remote controller and follow the steps below to conduct the test run. (1) Set the remote controller in T est Run mode. (Fig. 59a) a) Press and hold the QUIET button and the 1HR.
29 Pump Down Pump down means collecting all refrigerant gas in the system back into the outdoor unit without losing any of the gas.
