IMPORTANT! Please Read Before Starting When Installing… This air conditioning system meets strict safety and operating standards. As the installer or service person, it is an important part of your job to install or service the system so it operates safely and efficiently. …In a Room Properly insulate any tubing run inside a room to prevent “sweating” that can cause dripping and water damage to walls and floors.
2. The standards for minimum room volume are as follows. Check of Density Limit The room in which the air conditioner is to be installed requires a design that in the event of refrigerant gas leaking out, its density will not exceed a set limit. The refrigerant (R410A), which is used in the air conditioner, is safe, without the toxicity or combustibility of ammonia, and is not restricted by laws imposed to protect the ozone layer.

2. HOW TO INSTALL THE INDOOR UNIT Hole-in-anchor Hole-in-plug 2-1. Suspending the Indoor Unit Concrete Insert This unit uses a drain pump. Use a carpenter’s level to check that the unit is level. 2-2. Preparation for Suspending (1) Fix the suspension bolts securely in the ceiling using the method shown in the diagrams (Figs. 2-1 and 2-2), by attaching them to the ceiling support structure, or by any other method that ensures that the unit will be securely and safely suspended.
2-3. Placing the Unit Inside the Ceiling (2) (3) Full-scale installation diagram (printed on a cardboard packing) 48 mm When placing the unit inside the ceiling, determine the pitch of the suspension bolts using the supplied full-scale installation diagram. (Fig. 2-4) The size of the opening for the indoor unit can be confirmed by attaching the full-scale installation diagram beneath the unit. (Fig. 2-4) Tubing and wiring must be laid inside the ceiling when suspending the unit.
2-4. Installing the Drain Piping (1) Transparent part for checking drainage Prepare standard hard PVC pipe for the drain and use the supplied drain hose and hose band to prevent water leaks. The PVC pipe must be purchased separately. The transparent part allows you to check drainage. (Fig. 2-6) CAUTION (2) Packing (supplied) Tighten the hose clamps so their locking nuts face upward. (Fig. 2-6) Hard PVC pipe (not supplied) Drain hose adapter (supplied) Drain hose (supplied) 0964_X_I Fig.
2-5. Checking the Drainage After wiring and piping are completed, use the following procedure to check that the water will drain smoothly. For this, prepare a bucket and wiping cloth ready to catch and wipe up spilled water. Do not supply power to the unit until the tubing and wiring to the outdoor unit are completed. (1) Take off the tube cover and through the opening, slowly pour about 1,200 cc of water into the drain pan to check drainage.
■ Ceiling Panel CAUTION Never touch or attempt to move the air direction louver by hand or you may damage the unit. Instead, use the remote control unit if you want to change the direction or air flow. 2-6. Before Installing the Ceiling Panel (1) (2) Remove the air-intake grille and air filter from the ceiling panel. (Figs. 2-13 and 2-14) (a) Remove the 2 screws on the latch of the airintake grille. (Fig.
2-7. Installing the Ceiling Panel (1) Lift the ceiling panel and position it to align the (5) panel hook with the panel catch of the indoor unit. NOTE The ceiling panel must be mounted in the correct direction. Note that the 2 catches of the panel differ in size. Confirm that the catches are correctly matched between the ceiling panel and the indoor unit body. (2) Next, check to see that the ceiling panel is properly aligned with the seamline of the ceiling.
2-9. Duct for Fresh Air For fresh air intake 25 CMB-GSJ140U 36, 48 4ø3 . Type CMB-GSJ80U 60 Air-intake plenum 1 ho le ● There is a duct connection part on sideface of the indoor unit. (Fig. 2-16) ● Optional air-intake plenum (including duct connection box and flange) can be attached to the indoor unit. ø1 12 55 (1) Accessories ● Check that the following parts are in the box when unpacking. NAME QT’Y Detail of fresh air intake 2264_X_S Fig.
(e) Installing the ceiling panel ● Attach the ceiling panel to the chamber. Drawing the panel downwards sets the panel in position temporarily with the panel catch (at 2 locations). ● Remove the socket cover of the air-intake plenum and pass the 8P sockets through it. (Fix the panel lead wire to chamber side clamper.) (Fig. 2-17) ● Connect the 8P socket (electrical component box side) to the 8P socket (ceiling panel side) of the indoor unit electrical component box. ● Reattach the socket cover.
3. ELECTRICAL WIRING 3-1. General Precautions on Wiring (1) Before wiring, confirm the rated voltage of the unit as shown on its nameplate, then carry out the wiring closely following the wiring diagram. (7) Regulations on wire diameters differ from locality to locality. For field wiring rules, please refer to your LOCAL ELECTRICAL CODES before beginning.

CAUTION (1) When linking outdoor units in a network (S-net link system), disconnect the terminal extended from the short plug (CN003, 2P Black, location: right bottom on the outdoor main control PCB) from all outdoor units except any one of the outdoor units. (When shipping: In shorted condition.) Otherwise the communication of S-net link system is not performed. For a system without link (no connection wiring between outdoor units), do not remove the short plug.
(5) Use shielded wires for inter-unit control wiring (c) and ground the shield on both sides, otherwise misoperation from noise may occur. (Fig. 3-4) Connect wiring as shown in Section “3-3. Wiring System Diagrams.” WARNING Shielded wire Ground Loose wiring may cause the terminal to overheat or result in unit malfunction. A fire hazard may also exist. Therefore, ensure that all wiring is tightly connected. Ground Fig.
4. HOW TO PROCESS TUBING Deburring The narrow tubing side is connected by a flare nut, and the wide tubing side is connected by brazing. After Before 4-1. Connecting the Refrigerant Tubing Use of the Flaring Method Many of 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. Fig.
Caution Before Connecting Tubes Tightly (1) Apply a sealing cap or water-proof tape to prevent dust or water from entering the tubes before they are used. Apply refrigerant lubricant here and here (2) Be sure to apply refrigerant lubricant to the matching surfaces of the flare and union before connecting them together. This is effective for reducing gas leaks. (Fig. 4-4) Fig.
● ● Do not use a spanner to tighten the valve stem caps. Doing so may damage the valves. Packed valve Depending on the installation conditions, applying excessive torque may cause the nuts to crack. Charging port Valve stem Precautions for Packed Valve Operation ● ● ● If the packed valve is left for a long time with the valve stem cap removed, refrigerant will leak from the valve. Therefore, do not leave the valve stem cap removed.
4-4. Taping the Tubes (1) At this time, the refrigerant tubes (and electrical wiring if local codes permit) should be taped together with armoring tape in 1 bundle. To prevent the condensation from overflowing the drain pan, keep the drain hose separate from the refrigerant tubing. Clamp (2) Wrap the armoring tape from the bottom of the outdoor unit to the top of the tubing where it enters the wall. As you wrap the tubing, overlap half of each previous tape turn.
