Figure 7.
1.
Connect gauges and equipment as shown in Figure 7.
2.
Set the recovery machine for liquid recovery and start
the recovery machine. Open the gauge set valves to
allow the recovery machine to pull a vacuum on the
existing system line set and indoor unit coil.
3. Position the cylinder of clean R-410A for delivery of
liquid refrigerant and open its valve to allow liquid
refrigerant to flow into the system through the vapor
line valve. Allow the refrigerant to pass from the
cylinder and through the line set and the indoor unit
coil before it enters the recovery machine.
4.
After all of the liquid refrigerant has been recovered,
switch the recovery machine to vapor recovery so
that all of the R-410A vapor is recovered. Allow the
recovery machine to pull the system down to 0.
5.
Close the valve on the inverted R-410A drum and the
gauge set valves. Pump the remaining refrigerant out
of the recovery machine and turn the machine off.
