Installation Manual

1.8 Air Tight Test and Vacuum Drying

Note:

!

Always use nitrogen gas for the airtightness test.

!

Absolutely do not open the shutoff valve until the main power circuit insulation measurement
has been completed. (measuring after the shutoff valve is opened will cause the insulation
value to drop.)

1.8.1 Preparations

<Needed tools>

<The system for air tight test and vacuum drying>

!

Referring to figure 28, connect an nitrogen tank, refrigerant tank, and a vacuum pump to the
outdoor unit.
The refrigerant tank and the charge hose connection to refrigerant charge port or the valve
A, C in figure 28 are needed in “1-11. Additional Refrigerant Charge and Check Operation”.

!

The shutoff valve and valve A~C in figure 28 should be open or closed as shown in the table
below.

Note:

!

The airtightness test and vacuum drying should be done using the liquid
side and gas side shutoff valve service ports.
See the [R-410A] Label attached to the front plate of the outdoor unit for
details on the location of the service port (see figure at right).

!

See

[Shutoff valve operation procedure]

in “1-11-1 Before working” for

details on handling the shutoff valve.

!

The refrigerant charge port is connected to unit pipe.
When shipped, the unit contains the refrigerant, so use caution when
attaching the charge hose.

Gauge manifold

Charge hose valve

!

To prevent entry of any impurities and insure sufficient pressure resistance,

always use the special tools dedicated for R-410A.

!

Use charge hose that have pushing stick for connecting to service port of

shutoff valves or refrigerant charge port.

Vacuum pump

!

The vacuum pump for vacuum drying should be able to lower the pressure

to –100.7kPa (5 Torr –755mm Hg).

!

Take care the pump oil never flow backward into the refrigerant pipe during

the pump stops.
