01_EN_3PN14093-12A.fm Page 2 Friday, September 16, 2011 6:40 PM • Before touching electrical parts, turn off the unit. • Be sure to install a ground fault circuit interrupter if one is not already available. This helps prevent electrical shocks or fire. • Securely fasten the outdoor unit terminal cover (panel). If the terminal cover/panel is not installed properly, dust or water may enter the outdoor unit causing fire or electric shock.
01_EN_3PN14093-12A.fm Page 3 Friday, September 16, 2011 6:40 PM 2. BEFORE INSTALLATION • When moving the unit while removing it from the carton box, be sure to lift it by holding on to the four lifting lugs without exerting any pressure on other parts, especially, the refrigerant piping, drain piping, flanges and other resin parts. • Be sure to check the type of R410A refrigerant to be used before installing the unit. (Using an incorrect refrigerant will prevent normal operation of the unit.
01_EN_3PN14093-12A.fm Page 4 Friday, September 16, 2011 6:40 PM 2-3 OPTIONAL ACCESSORIES b. Items to be checked at time of delivery • These is one type of remote controller: wired. Items to be checked NOTE Are you sure the control box cover, air filter, air inlet grille, and air outlet grille are mounted? • If you wish to use a remote controller that is different from the above, select a suitable remote controller after consulting catalogs and technical materials.

01_EN_3PN14093-12A.fm Page 6 Friday, September 16, 2011 6:40 PM (2) Mount the canvas ducts to the air outlet and inlet so that the vibration of the air conditioner will not be transmitted to the duct or ceiling. Apply a sound-absorbing material (insulation material) to the inner wall of the duct and vibration insulation rubber to the suspension bolts (refer to 8. DUCT WORK). (3) Open installation holes (if the ceiling already exists). • Open the installation holes on the ceiling.
01_EN_3PN14093-12A.fm Page 7 Friday, September 16, 2011 6:40 PM CAUTION • Use the level and check that the unit is installed horizontally. (4-directions) • In the case of using a vinyl tube (filled with water) in place of the level, align the bottom of the unit to the water surface at both edges of the vinyl tube to make levelness adjustment. If the unit is installed at a slant with the drain pipe side set high, in particular, the float switch will not operate normally and water leakage may result.

01_EN_3PN14093-12A.fm Page 9 Friday, September 16, 2011 6:40 PM • The drain piping will be clogged with water and water leakage may result if the water is accumulated in the drain piping. • Select the diameter of the concentrated drain piping to suit the capacity of equipment connecting to the concentrated drain piping (see the equipment design sheet). Ceiling slab 12 in. max. • Conduct drain-up piping work if the gradient is insufficient. • Attach a support bracket at 3.3 to 4.
01_EN_3PN14093-12A.fm Page 10 Friday, September 16, 2011 6:40 PM The drainage can be checked with the water level change in the drain pan through the water inlet. CAUTION • Do not touch the drain pump. Otherwise, an electric shock may be received. • Do not impose external force on the float switch. Otherwise, a failure may result. 5. On completion of the drainage check, shut off the power supply and disconnect the power supply line. 6. Put the control box cover to the original position.
