[. . . ] Ce manuel dcrit la procdure d'installation de l'unit intrieure. Pour installer l'unit extrieure, reportez-vous au Manuel d'installation fourni avec l'unit extrieure. Bitte lesen Sie dieses Handbuch sorgfltig, bevor Sie mit der Installation des Klimagertes beginnen. In diesem Handbuch wird die Installation der Raumeinheit beschrieben. [. . . ] For connection with the drain pipe connecting port, be sure to use/fix the attached flexible hose with the hose band, otherwise a damage or water leak is caused on the drain pipe connecting port. Attached hose band Drain pipe connecting port (Hard socket) VP25 vinyl chloride pipe (To be local procure) Attached flexible hose Drain pipe connecting port (Transparent) Indoor unit body Align the attached hose band to the end of hose, set the tightening position upward, and then tighten it. Flexible hose (Accessory) VP25 vinyl chloride pipe (To be local procure) Soft socket Socket for VP25 (To be local procure) Hard socket Socket for VP25 vinyl chloride pipe (To be local procure) Adhesive inhibited : Use the attached flexible hose and hose band for connecting the drain hose to the clear drain socket. If applying the adhesive, socket will be damaged and cause water leakage. Flexible hose Use the attached flexible hose to adjust core discrepancy of the hard vinyl chloride pipe or to adjust the angle. Do not use the flexible hose as stretched, or do not deform it more extent than that in the following figure. Be sure to fix the soft end of the flexible hose with the attached hose band. Use the flexible hose on a horizontal level. OK max 45 max 45 NO GOOD Riser (Trap) 90 Bend 9 Connection procedure Connect a socket and a hard vinyl chloride pipe. Using adhesive agent for vinyl chloride pipe, connect the drain pipes certainly so that water does not leak. 10 hours to dry and harden the adhesive agent. During this period, do not apply force to the connecting part with the drain pipe. Check the draining In the test run, check that water drain is properly performed and water does not leak from the connecting part of the pipes. Be sure to check draining also when installed in heating period. Using a pitcher or hose, pour water (1500 to 2000cc) into the discharge port before installation of the ceiling panel. Otherwise, the nut may crack depending on the conditions. of copper pipe Tightening torque 14 to 18 (1. 4 to 1. 8 kgfm) 33 to 42 (3. 3 to 4. 2 kgfm) 50 to 62 (5. 0 to 6. 2 kgfm) 63 to 77 (6. 3 to 7. 7 kgfm) Permissible Piping Length and Heat They vary according to the outdoor unit. For details, refer to the Installation Manual attached to the outdoor unit. 6. 4 mm (diam. ) 9. 5 mm (diam. ) 12. 7 mm (diam. ) 15. 9 mm (diam. ) Flaring Insert a flare nut into the pipe, and flare the pipe. As the flaring sizes of R410A differ from those of refrigerant R22, the flare tools newly manufactured for R410A are recommended. B However, the conventional tools can be used by adjusting projection margin of the copper pipe. Tightening torque of flare pipe connections Pressure of R410A is higher than that of R22. 1. 6 times) Therefore, using a torque wrench, tighten the flare pipe connecting sections Flare at which connect the indoor indoor and outdoor units of the unit side specified tightening torque. Incorrect connections may cause not only a gas leak, but also a trouble of the refrigeration cycle.

Then tighten the nut with a spanner and torque wrench as shown in the figure. Half union Flare nut Internally threaded side Use a torque wrench to tighten.
