• Tightening torque of flare pipe connections
The operating pressure of R32 is
higher than that of R22 (approx.
1.6 times). It is therefore necessary
to firmly tighten the flare pipe
connecting sections (which connect
the indoor and outdoor units) up to the
specified tightening torque. Incorrect
connections may cause not only a
gas leakage, but also damage to the
refrigeration cycle.
Evacuating
After the piping has been connected to the indoor unit, you can perform the
air purge together at once.
AIR PURGE
Evacuate the air in the connecting pipes and in the indoor unit using a
vacuum pump. Do not use the refrigerant in the outdoor unit.
For details, see the manual of the vacuum pump.
Be sure to use a vacuum pump with counter-flow prevention function so that
inside oil of the pump does not flow backward into pipes of the air conditioner
when the pump stops.
(If oil inside of the vacuum pump enters the air conditioner, which use R32,
refrigeration cycle trouble may result.)
1. Connect the charge hose from the manifold valve to the service port of the
packed valve at gas side.
2. Connect the charge hose to the port of the vacuum pump.
3. Open fully the low pressure side handle of the gauge manifold valve.
4. Operate the vacuum pump to start evacuating. Perform evacuating for
about 15 minutes if the piping length is 25 meters.
(15 minutes for
25 meters) (assuming a pump capacity of 27 liters per minute) Then confirm
that the compound pressure gauge reading is –101 kPa (–76 cmHg).
5. Close the low pressure side valve handle of the gauge manifold valve.
6. Open fully the valve stem of the packed valves (both gas and liquid sides).
7. Remove the charging hose from the service port.
8. Securely tighten the caps on the packed valves.
