CONTENTS 1. SAFETY CONSIDERATIONS........................................... 1 2. BEFORE INSTALLATION................................................. 3 • Safely dispose all packing and transportation materials in accordance with federal/state/local laws or ordinances. Packing materials such as nails and other metal or wood parts, including plastic packing materials used for transportation may cause injuries or death by suffocation. 3. CHOOSING AN INSTALLATION SITE............................. 4 4.
• Do not touch the switch with wet fingers. Touching a switch with wet fingers can cause electric shock. • Do not allow children to play on or around the unit to prevent injury. • The heat exchanger fins are sharp enough to cut. To avoid injury wear gloves or cover the fins while working around them.
2. BEFORE INSTALLATION 2-2 OPTIONAL ACCESSORIES When unpacking the indoor unit or moving the unit after unpacked, hold the hangers (4 places) and do not apply force to other parts (particularly refrigerant piping, drain piping). • For installation of the outdoor unit, refer to the installation manual attached to the outdoor unit. • Do not throw away the accessories until the installation work is completed.
Items to be checked Check Have you carried out field setting? (if necessary) Are the electrical wiring box cover, air filter, suction grille attached? Does the cool air discharge during the COOL operation and the warm air discharge during the HEAT operation? Does the indoor unit makes unpleasant sound of air discharge? Did you explain about operations while showing the operation manual to your user? Have you explained the description of COOL, HEAT, DRY and AUTOMATIC (cooling/heating) given in the operatio

(5) Install the suspension bolts. • Use M8 or M10 bolts for hanging the indoor unit. Use hole-in-anchors for the existing bolts and embedded inserts or foundation bolts for new bolts, and fix the indoor unit firmly to the building so that it may withstand the mass of the unit. In addition, adjust clearance (1-15/16 inch (50mm) 3-15/16 inch (100mm)) from the ceiling in advance. 5. INDOOR UNIT INSTALLATION Depending on the optional parts, it may be easier to attach them before installing the indoor unit.
CAUTION WARNING • Install the indoor unit leveled. If the indoor unit is inclined and the drain piping side gets high, it may cause malfunction of float switch and result in water leakage. • Attach nuts on the upper and lower side of hanger. If there is no upper nut and the lower nut is over-tightened, the hanger and the top plate will deform and cause abnormal sound. • Do not insert materials other than that specified into the clearance between the hanger and the washer for hanger bracket (11).
Tighten Gas Piping Insulation Procedure Fitting insulation (5) Torque wrench Spanner Piping union Flare nut connection Piping insulating material (unit) Bring the seam to the top. Do not leave clearance. Flare nut Wind around the piping until top of the flare nut connection, beginning at the base. Unit Fig. 9 Apply oil Do not apply refrigeration oil to the outer surface. English • The refrigerant is pre-charged in the outdoor unit. Apply refrigeration oil only to the inner surface of the flare.
7. DRAIN PIPING WORK 40-60 inch (1000-1500mm) Tightened part approx. 90° (1) Carry out drain piping. Carry out drain piping so that drainage is ensured. • Select the piping diameter equal to or larger than (except for riser) that of the connection piping (polyvinyl chloride piping, nominal diameter 1 inch (25mm), outside diameter 1-1/4 inch (32mm)).
29-9/16 inch (675mm) • T o avoid the attached drain hose (2) getting excessive force, do not bend nor twist it. It may cause water leakage. • As for drain piping connection, do not connect the drain hose directly to a sewage that gives off ammonia odor. (The ammonia in the sewage may go through the drain piping and corrode the heat exchanger of the indoor unit.) • In case of centralized drain piping, carry out piping work according to the procedure shown in the following Fig. 16.
8. DUCT WORK 9. ELECTRIC WIRING WORK Pay the utmost attention to the following items and conduct the duct work. 9-1 GENERAL INSTRUCTIONS • Check that the duct is not in excess of the setting range of external static pressure for the unit. (Refer to the technical datasheet for the setting range.) • Attach a canvas duct each to the air outlet and air inlet so that the vibration of the equipment will not be transmitted to the duct or ceiling.
For the wiring of outdoor units, refer to the installation manual attached to the outdoor units. Confirm the system type. • Multi system: 2 through 6 (The number of connectable units will vary according to model) indoor units connect to 1 outdoor unit. The indoor unit is controlled by remote controller connected to each indoor unit. Multi system • Connect the terminal as shown in Fig. 22. When installing a single core wire. • Do not carry out soldering finish when stranded wirings are used.
(2) Attach the conduit to the conduit mounting plate (12). Conduit mounting plate (12) Lock nut (field supply) Fig. 24-1 • Attach the wire sealing pad (small) (10) to the conduit, the wiring between the indoor and outdoor units, and the ground wiring.

CAUTION Before carrying out field setting, check the items mentioned in 1. Items to be checked after the installation work is completed on page 3. • Check if all the installation and piping works for the air conditioner are completed. • Check that the outside panel and piping cover of the indoor and outdoor units are closed. < FIELD SETTINGS > After turning on the power supply, carry out field setting from the remote controller according to the installation state. • Carry out setting at 3 places, “Mode No.
(b) Select external static pressure with the remote controller. Check with Mode No. [21] per indoor unit that the SECOND CODE No. for the above “Air volume adjustment” is set to “01” (OFF). (The SECOND CODE No. is factory set to “01” (OFF).) Change the SECOND CODE No. by referring to the table below according to the external static pressure of the duct to be connected. Table 5 30Pa 40Pa 50Pa 60Pa 70Pa 80Pa 90Pa 100Pa 110Pa 120Pa 130Pa 140Pa 150Pa Table 5 FIRST CODE No. Mode No.
1) Set to COOL or HEAT operation using the remote controller. 2) Press and hold Cancel button for 4 seconds or longer. Service settings menu is displayed. 3) Select Test Operation in the service settings menu, and press Menu/OK button. Basic screen returns and “Test Operation” is displayed at the bottom. 4) Press On/Off button within 10 seconds, and the test operation starts. Monitor the operation of the indoor unit for a minimum of 10 minutes.
For wireless remote controller 1) Press MODE /TEST 2) Press and select the COOL or HEAT operation. twice. “Test” is displayed. ON OFF 3) Press starts. within 10 seconds, and the test operation Monitor the operation of the indoor unit for a minimum of 10 minutes. During test operation, the indoor unit will continue to cool/heat regardless of the temperature setpoint and room temperature. • In the case of above-mentioned procedures 1) and 2) in reverse order, test operation can start as well.
• For places where the malfunction code is written in white, the “ ” indication is not displayed. Though the system continues operating, be sure to inspect the system and make repairs as necessary. • Depending on the type of indoor or outdoor unit, the malfunction code may or may not be displayed.
