Thank you very much for purchasing TOSHIBA Air Conditioner. Please read this owner's manual carefully before using your Air Conditioner.

For an airtight test, connect a nitrogen gas bomb as shown in the figure below, and apply pressure. · Be sure to apply pressure from the service ports of the packed valves (or ball valves) at liquid side, discharge gas side, balance pipe and suction gas side. · An air tight test can be only performed to the service ports at liquid side, discharge gas side, and suction gas side of the outdoor unit. · Close fully valves at liquid side, discharge gas side, balance pipe and suction gas side. As there is possibility that nitrogen gas enters in the refrigerant cycle, re-tighten the valve rods before applying pressure. (Re-tightening of the valve rods are unnecessary for valves at discharge gas side because they are ball valves. ) · For each refrigerant line, apply pressure gradually with steps at liquid side, discharge gas side, balance pipe and suction gas side. Be sure to apply pressure to suction gas side, discharge gas side, liquid side and balance pipe. REQUIREMENT Never use "Oxygen", "Flammable gas" and "Noxious gas" in an airtight test.

Available to detect a gross leakage STEP 2 : Apply pressure 1. 5MPa (15kg/cm2G) for 3 minutes or more. STEP 3 : Apply pressure 3. 73MPa (38kg/cm2G) for approx. Available to detect slow leakage · Check pressure down. No pressure down: Accepted Pressure down: Check the leaked position. However, if there is difference of ambient temp. between when pressure has been applied and when 24 hours passed, pressure changes by approx. Leaked position check When a pressure-down is detected in STEP 1, STEP 2, or STEP 3, check the leakage at the connecting points. Check leakage with hearing sense, feeler, foaming agent, etc, and perform re-brazing or re-tightening of flare if leakage is detected. 39 Air purge For the air purge at installation time (Discharge of air in connecting pipes), use "Vacuum pump method" from viewpoint of protection of earth environment. · For protection of earth environment, do not discharge the flon gas in the air. · Using a vacuum pump, eliminate the remained air (nitrogen gas, etc. ) in the unit. If gas remains, an absence of faculties may be caused. After the airtight test, discharge nitrogen gas. Then connect the gauge manifold to the service ports at suction gas side, discharge gas side and liquid side, and connect the vacuum pump as shown in the following figure. Be sure to perform vacuuming for suction gas side, discharge gas side, liquid side and balance pipe. · Be sure to perform vacuuming from both suction gas side, discharge gas side, liquid side and balance pipe.
