Evacuating

E N G L I S H

Air Purge

With respect to the preservation of terrestrial environment, adopt “Vacuum pump” for air purge (Evacuate air in the connecting pipes) when installing the unit.

•Do not discharge the refrigerant gas to the atmosphere to preserve the terrestrial environment.

•Use a vacuum pump to discharge the air (nitrogen, etc.) remained in the set. If the air remains, the capacity may decrease.

For the vacuum pump, be sure to use one with backflow preventer so that the oil in the pump does not backflow into the pipe of the air conditioner when the pump stops.

(If oil in the vacuum pump is put in an air conditioner including R410A, it may cause trouble on the refrigeration cycle.)

Vacuum pump

•As shown in the right figure, connect the charge hose after the manifold valves are closed completely.

•Attach the connecting port of the charge hose with a projection to push the valve core (setting pin) to the charge port of the set.

•Open handle Low fully.

•Turn ON the vacuum pump.(*1)

•Loosen the flare nut of the packed valve (Gas side) a little to check the air passes through.(*2)

•Tighten the flare nut again.

•Execute vacuuming until the compound pressure gauge indicates –101kPa (–76cmHg). (*1)

•Close handle Low completely.

•Turn OFF the vacuum pump.

•Leave the vacuum pump as it is for 1 or 2 minutes, and check the indicator of the compound pressure gauge does not return.

•Open fully the valve stem or the valve handle. (First, at liquid side, then gas side)

•Disconnect the charge hose from the charge port.

•Tighten valve and caps of the charge port surely.

*1. Use the vacuum pump, vacuum pump adapters, and gauge manifold referring to the manuals attached to each tool before using them. For the vacuum pump, check oil is filled up to the specified line of the oil gauge.

*2. While the air is purged, check again that the connecting port of charge hose, which has a projection to push the valve core, is firmly connected to the charge port.
