GENERAL INFORMATION
1.1 Specific features The “Mitsubishi Daiya” room air-conditioner: SRK series are of split and wall mounted type and the unit consists of indoor unit and outdoor unit with refrigerant precharged in factory. The indoor unit is composed of room air cooling or heating equipment with operation control switch and the outdoor unit is composed of condensing unit with compressor. (1) Inverter (Frequency converter) for multi-steps 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 start-up period. Constant room temperature by fine-tuned control after the unit has stabilized. (2) Fuzzy control ¡ Fuzzy control calculates the amount of variation in the difference between the return air temperature and the setting temperature in compliance with the fuzzy rules in order to control the air capacity and the inverter frequency. (3) Remote control flap & louver The Flap & louver can be automatically controlled by operating wireless remote control. ¡ Flap swing : The flaps swing up and down successively. ¡ Louver swing : The louvers swing left and right successively. ¡ Multi-directional Air Flow : Activating both up/down air swing and left/right air swing at the same time results in a multidirectional air flow. ¡ Memory flap : Once the Flap & louver position is set, the unit memorizes the position and continues to operate at the same position from the next time. (4) 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.

INSTALLATION
R410A refrigerant is used for this air-conditioner. Execute the installation work while taking care of the following points in addition to the general caution items.
5.1 Installation tools Prepare the following special tools for R410A in addition to the general-purpose tools. ¡Flare tool
¡Vacuum pump adaptor
¡Gauge manifold
¡Leak detector
¡Charge hose
5.2 Refrigerant piping ¡Use the copper pipe that has less than 40 mg/10 m of oil adhesion and 0.8 mm of wall thickness. Never use the thin walled pipe the thickness of which is less than 0.8 mm. ¡Use the flare nut attached to the air-conditioner.

(3) Vacuuming ¡
The charge hose for R22 cannot be connected because the service port diameter is different from the conventional one. Use the special charge hose for R410A.
¡
Use the vacuum pump adapter for reverse flow prevention to check the reverse flow of vacuum pump oil. If oil flows back to the air-conditioner, it causes failure of refrigerant cycle. Service valve (Two-way)
