Contents 1 PRECAUTIONS FOR SAFETY . 4 3 INSTALLATION OF NEW REFRIGERANT AIR CONDITIONER . 32 Thank you for purchasing this Toshiba air conditioner. This Installation Manual describes the installation method of the outdoor unit. [. . . ] Apply pressure 0. 3MPa (3. 0kg/cm²G) for 5 minutes or more. Apply pressure 1. 5MPa (15kg/cm²G) for 5 minutes or more. Apply pressure 3. 73MPa (38kg/cm²G) for approx. · If there is no pressure decrease after 24 hours, the test is passed. EN 27-EN ­ 14 ­ 28-EN 29-EN ­ 15 ­ SMMS-i Installation Manual SMMS-i Installation Manual 30-EN NOTE However, if the environmental temperature changes from the moment of applying pressure to 24 hours after that, the pressure will change by about 0. 01MPa (0. 1kg/cm²G) per 1°C. Consider the pressure change when checking the test result. Vacuum drying · Be sure to perform vacuuming from both liquid and gas sides. · Be sure to use a vacuum pump equipped with the counter-flow prevention function so that oil in the pump will not flow back into piping for air conditioners. (If oil in the vacuum pump enters in the air conditioner with R410A refrigerant, a problem may be caused in the refrigerating cycle. ) After finishing the airtight test and discharging nitrogen gas, connect the gauge manifold to the service ports of the liquid side, gas side, and balance pipe side and connect a vacuum pump as shown in the figure below. Be sure to perform vacuuming for the liquid, gas, and balance pipe sides. Low pressure High pressure gauge gauge REQUIREMENT When pressure decrease is detected in steps 1-3, check the leakage at the connecting points. Check the leakage using a foaming agent or other measures and seal the leak with re-brazing, flare retightening or other methods. After sealing, execute an airtight test again.

Check that all the packed valves at the liquid side, gas side, and balance pipe side are fully closed. · If the pressure does not reach -100. 7kPa or less, continue vacuuming for 1 hour or more. If the pressure does not reach -100. 7kPa after 3 hours of vacuuming, stop vacuuming and check for air leakage. · If the pressure reaches -100. 7kPa or less after vacuuming for 2 hours or more, close the valves VL and VH on the gauge manifold fully and stop the vacuum pump. Leave it as it is for 1 hour to confirm that the vacuuming degree does not change. If the degree of vacuum loss is large, moisture may remain in the pipes. In that case, inject dry nitrogen gas and apply pressure to 0. 05MPa and perform vacuuming again. · After finishing the above procedure of vacuuming, exchange the vacuum pump with a refrigerant canister and advance to the additional charging of refrigerant.
