- Caution keep in mind that if the phosphor copper brazing filler metal is used and the brazing temperature and the heating time exceed a certain point the phosphor changes into the gaseous state e g bcup 1 to 5 between 700 and 800c which causes pin holes and results in refrigerant leakage 41
- Caution to be taken when brazing refrigerant piping do not use flux when brazing copper to copper refrigerant piping particularly for the hfc refrigerant piping therefore use the phosphor copper brazing filler metal bcup which does not require flux flux has extremely harmful influence on refrigerant piping systems for instance if the chlorine based flux is used it will cause pipe corrosion or in particular if the flux contains fluorine it will damage the refrigerant oil the use of flux is strictly forbidden since the cleaning on site is impossible 41

- Caution be sure to ground the air conditioner do not connect the earth wire to a gas pipe water pipe lightning conductor or telephone earth wire use only copper wires 47
- Cautions as this unit is equipped with an inverter installing a phase advancing capacitor not only will deteriorate power factor improvement effect but also may cause a capacitor abnomal heating accident due to high fre quency waves therefore never install a phase advancing capacitor keep power imbalance to within 2 of the supply rating 1 large imbalance will shorten the life of the smoothing capacitor 2 as a protective measure the product will stop operating and an error indication will be made when power imbalance exceeds 4 of the supply rating when installing the leakage breaker make sure it is an inverter type high frequency high freq non sensing type breaker 47
- The wiring between the indoor unit and outdoor unit must be for 220v do not turn on the main switch until all the wiring is complated the resistance of the grounding must not exceed 500 when performing electrical wiring refer also to the wiring diagram affixed to the unit use the specified wires and fix them with clamps so that no external forces act on the terminals for clamp ing push the hook in tail end of the clamp to loosen it pass the wires through it then fasten the clamp clamp the wiring as shown below taking care that the wires do not touch the piping especially high pres sure piping never squeeze extra wires into the unit when leading out the wires to the front or side you can use a wire conduit passing through the knock out hole 34mm when you don t use a wire conduit be sure to protect the wires with vinyl tubes etc to pre vent the edge of the knock out hole from cutting the wires form the wires and fix the cover firmly so that the cover may be fit in properly 47

- Pump down residual operation 103
- A when cooling the indoor fan is operated with upper limit l until the low pressure reaches 0 mpa 104
- B hot startup control only in heating operation when startup or after defrosting has been completed in heating operation controls indoor unit fan to prevent cool air from blasting and secure the startup performance 104
- Following indoor fan control is conducted with instruction from outdoor unit 104
- Indoor fan control at compressor startup 104
- Indoor fan control before compressor startup 104
- Indoor fan control before compressor stop 104
- Indoor fan control during compressor stop 104
- Indoor unit fan control 104
- The residual operation of indoor unit fan is conducted before compressor stop during pump down residual operation to startup compressor smoothly next time cooling operation minimizes the residual refrigerant amount in indoor unit heat exchanger heating operation lowers the high pressure by discharging stagnant air around the indoor unit heat exchanger indoor fan control before compressor stop 104
- When the unit operation is turned off by remote controller the indoor fan stops once however if the 1 step up signal for indoor fan is received from outdoor unit rotates again with ll tap 104
- Outdoor unit low noise control 105
- Setting mode 105
- Test run control 105
- C setting by capacity precedence when setting dip switches ds1 4 on the outdoor unit pc board to on activates capacity precedence setting in both a and b if the air conditioning load increases the low noise operation stops to return to normal operation when setting the dip switches ds1 4 to off precedes the low noise operation even if the air conditioning load increases the low noise operation continues 106
- Emergency operation 106
- Since the night time judgement 22 8 o clock is made in accordance with outside temperature the night time is a target only 106
- Transmission between indoor and outdoor units is not conducted in cooling operation on for 20 minutes and off for 10 minutes are conducted in succession in heating operation defrosting is conducted once every 1 hour for 3 minutes in other conditions than the above mentioned the same control as normal control is conducted 106
