Installation Process Installation Process Determination of division work Preparation of contract drawings Sleeve and insert work Installation of indoor unit Refrigerant piping work Drain pipe work Duct work Heat insulation work Electrical work (connection circuits and drive circuits) Outdoor unit foundation work Installation of outdoor unit All tight test Vacuum drying Additional charge of refrigerant Fit facing panels Automatic addressing of indoor unit Test run adjustment Transfer to customer with explanation 10 Outdoor Unit Indicate clearly who is to be responsible for switch settings. Make relationship between outdoor, indoor, remote controller, and option connections clear.(Prepare control circuit diagram) Take account of gradient of drain piping. Check model name to make sure the fitting is made correctly. Special attention to dryness, cleanness and tightness. Adjust to downward gradient. Make sure airflow is sufficient. Make sure no gaps are left where the insulating materials are joined. Multiple core cable must not be used.(suitable cable should be selected) The foundation must be level. Avoid short circuits and ensure sufficient space is allowed for service. In the final check for 24hours at 3MPa(30.0 kg/cm 2 ) there must be no drop in pressure. The vacuum pump must have a capacity of reaching at least 5mmHg, 3hours Recharge correctly as calculated in this manual, and record the amount of additional refrigerant. Make sure there are no gaps left between the facing materials used on the ceiling. Refer to automatic addressing flowchart. Run each indoor unit in turn to make sure the pipe work has been fitted correctly. Explain the use of the system as clearly as possible to your customer and make sure all relevant documentation is in order. The above list indicates the order in which the individual work operations are normally carried out but this order may be varied where local conditions warrants such change.
