4 GENERAL INFORMATION. Specific features () The long piping makes the location of the inside and units flexible. No need for additional charge of refrigerant : 45 type 20m, 60 type 0m, 80 type 40m Maximum piping length : 45 type 0m, 60 type 40m, 80 type 60m (2) Connectable indoor capacity Number of connectable units : 45 type 2 units, 60 type units, 80 type 4 units Total of indoor units (class kw) : 45 type 7.0kw, 60 type 0.6kw, 80 type kw () Indoor units are available with 5 capacities. 5 capacities... 22, 25, 28, 5, 50, 60 Types... Wall mounted type (SKM). 4way ceiling cassette type (STM). Ducted type (SRRM). (4) Inverter (Frequency converter) for multisteps power control Heating / Cooling The rotational speed of a compressor is changed in step in relation to varying load, to interlock with the indoor and outdoor unit fans controlled to changes in frequency, thus controlling the power. Allowing quick heating/cooling operation during startup period. Constant room temperature by finetuned control after the unit has stabilized. (5) Fuzzy control Fuzzy control calculates the amount of variation in the difference between the suction air temperature and the setting temperature in compliance with the fuzzy rules in order to control the air capacity and the inverter frequency. (6) Self diagnosis function We are constantly trying to do better service to our customers by installing such judges that show abnormality of operation as follows..2 How to read the model name Example : ST M 25 Z D S R40A models Series No. Inverter and Heat pump type Product capacity Multiple system Model name SK : Wall mounted type ST : 4 way ceiling cassette type SRR : Ducted type SC : Outdoor unit

36 5 INSTALLATION R40A refrigerant is used for this airconditioner. Execute the installation work while taking care of the following points in addition tothe general caution items. 5. Installation tools Prepare the following special tools for R40A in addition to the generalpurpose tools. Flare tool Gauge manifold Charge hose Vacuum pump adaptor Leak detector 5.2 Refrigerant piping Use the copper pipe that has less than 40 mg/0 m of oil adhesion and 0.8 mm of wall thickness. Never use the thin walled pipe thethickness of which is less than 0.8 mm. Use the flare nut attached to the airconditioner. 5. Pipe connection () Pipe working Copper pipe dia.

Usethe special charge hose for R40A. Use the vacuum pump adapter for reverse flow prevention to check the reverse flow of vacuum pump oil. If oil flows back tothe airconditioner, it causes failure of refrigerant cycle. 0kPa (76cmHg) Handle Lo Charge Hose (Special for R40A) Compound pressure gauge Pressure gauge Gauge manifold (Special for R40A) Handle Hi Charge hose (Special for R40A) Vacuum pump adaptor (For reverse flow prevention) (Special for R40A) Vacuum Pump
