English Safety Precautions • Read these Safety Precautions carefully to ensure correct installation. • This manual classifies the precautions into DANGER, WARNING and CAUTION. Be sure to follow all the precautions below: they are all important for ensuring safety. DANGER...........Indicates an imminently hazardous situation which, if not avoided, will result in death or serious injury. WARNING.........
Safety Precautions WARNING • After connecting all wiring be sure to shape the cables so that they do not put undue stress on the electrical covers, panels or terminals. Install covers over the wires. Incomplete cover installation may cause terminal overheating, electrical shock, fire or equipment damage. • When installing or relocating the system, be sure to keep the refrigerant circuit free from all substances other than the specified refrigerant (R410A), such as air.
English Choosing an Installation Site • Before choosing the installation site, obtain user approval. 1. Indoor unit CAUTION • When moving the unit during or after unpacking, make sure to lift it by holding its lifting lugs. Do not exert any pressure on other parts, especially the refrigerant piping, drain piping and flange parts. Wear protective gear (such as gloves) when installing the unit.
Choosing an Installation Site 2. Wireless remote controller • Turn on all the fluorescent lamps in the room, if any, and find the site where remote controller signals are properly received by the indoor unit (within 13ft (4m)). 3. Outdoor unit • For outdoor unit installation, see the installation manual supplied with the outdoor unit. Preparations before Installation ■■Relation of the unit to the suspension bolt positions.
Sealing pad (Small) (accessory) (3) English (3) Attach sealing pad as shown in the right figure. (Stored in outlet vent) (only for CDXS) (In order to take in the air inside the ceiling, and when not taking in air from outdoor air, it is not necessary to stick.) • Attach the sealing pad (accessory) to the plate metal sections which are not covered by anti-sweat material. • Make sure there are no gaps between the different pieces of sealing pad.
Indoor Unit Installation << As for the parts to be used for installation work, be sure to use the provided accessories and specified parts designated by our company. >> ■■Install the indoor unit temporarily. • Attach the hanger bracket to the suspension bolt. Be sure to fix it securely by using a nut and washer from the upper and lower sides of the hanger bracket. (Refer to Fig.
English Refrigerant Piping Work See the installation manual supplied with the outdoor unit. 1. Flaring the pipe end 1) Cut the pipe end with a pipe cutter. 2) Remove burrs with the cut surface facing downward so that the chips do not enter the pipe. 3) Put the flare nut on the pipe. 4) Flare the pipe. 5) Check that the flaring is properly made. (Cut exactly at right angles.) Set exactly at the position shown below.
Refrigerant Piping Work CAUTION Be sure to insulate any field piping all the way to the piping connection inside the unit. Any exposed piping may cause condensation or burns if touched. Cautions on Pipe Handling • Protect the open end of the pipe against dust and moisture. (Tighten both edges with clamp.) • All pipe bends should be as gentle as possible. Use a pipe bender for bending. (See the minimum bend radius in the table below.) Wall Be sure to place a cap.
English CAUTION • Water accumulating in the drain piping can cause the drain to clog. • To keep the drain tube from sagging, space hanging wires every 3 (1) to 5ft (1.5m). • Use the drain hose and the metal clamp. Insert the drain hose fully into the drain socket and firmly tighten the metal clamp with the upper part of the tape on the hose end. Tighten the metal clamp until the screw head is less than 1/8 inch (4mm) from the hose.
Installing the Duct Outlet side • Connect the duct according to the inside of the outlet-side flange. • Wrap the outlet-side flange and the duct connection area with aluminum tape or something similar to prevent air escaping. Flange (field supply) Flange Main unit Connection screw (accessory) Insulation material (field supply) Aluminum tape (field supply) Aluminum tape (field supply) Air inlet side Outlet side CAUTION • Be sure to insulate the duct to prevent condensation from forming.
• When doing the wiring, make sure the wiring is neat and does not cause the control box cover to stick up, then close the cover firmly. When attaching the control box cover, make sure you do not pinch any wires. • Outside the unit, separate the low voltage wiring (remote controller wiring) and high voltage wiring (ground wire and power supply wiring) at least 5in so that they do not pass through the same place together. Proximity may cause electrical interference, malfunctions, and breakage.
Trial Operation and Testing 1. Trial operation and testing (1) Measure the supply voltage and make sure that it falls in the specified range. (2) Trial operation should be carried out in either cooling or heating mode. Trial operation from remote controller (1) Press ON/OFF button to turn on the system. (2) Simultaneously press center of TEMP button and MODE button. (3) Press MODE button twice. (“ ” will appear on the display to indicate that Trial Operation mode is selected.
