Contents 1 PRECAUTIONS FOR SAFETY . This Installation Manual describes the installation method of the outdoor unit. For installation of indoor units, follow the Installation Manual supplied with the indoor unit. Moreover, as this installation manual includes the important articles concerning the "Machinery" Directive (Directive 2006/42/ EC), please read through the manual and make sure you understand it. [. . . ] When piping to outdoor units using Outdoor unit connection piping kits, intersect the pipes to the outdoor unit and those to indoor units at a right angle as shown in figure 1 on "6. INSTALLATION OF THE OUTDOOR UNIT". · Be sure to apply pressure from the service ports of the packed valves (or ball valves) at the liquid side, gas side and balance pipe side. · An airtight test can only be performed at the service ports at the liquid side, gas side and balance pipe side on header unit. · Close the valves fully at the gas side, liquid side and balance pipe side. As there is a possibility that the nitrogen gas will enter into the cycle of outdoor units, re-tighten the valve rods at the liquid side and balance pipe side before applying pressure. (When using MAP140 or MAP160, you do not have to re-tighten the liquid side valve rod as their valves at the liquid side are ball valves. ) · For each refrigerant line, apply pressure gradually in steps at the liquid side, gas side and balance pipe side. Be sure to apply pressure at the gas side, liquid side, and balance pipe side. WARNING Never use oxygen, flammable gases, or noxious gases in an airtight test.

Make the difference 50m or less if the height difference between indoor units (H2) is more than 3m. Make the difference 30m or less if the height difference between indoor units (H2) is more than 3m. Able to detect a serious leakage 1. · 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.
