valve.
2 Connect the micron gauge between vacuum pump and service port of outdoor units.
3 Turn on the power switch of the vacuum pump and make sure that connect digital micron gauge and to pull
down to a value of 500 microns.
4 To make sure micron gauge a value 500 microns and close the low side valve of the charging set and turn off
the vacuum pump.
5 Disconnect the vacuum pump house from the service port of the 3-way valve.
6 Tighten the service port caps of the 3-way valve at a torque of 13.3 Ibf.ft (18 N•m) with a torque wrench.
7 Remove the valve caps of both of the 2-way valve and 3-way valve. Position both of the valves to “Open”
using a hexagonal wrench (5/32" (4 mm)).
8 Mount valve caps onto the 2-way valve and the 3-way valve.
oBe sure to check for gas leakage.
If micron gauge value does not descend 500 microns, take the following measures:
- If the leak stops when the piping connections are tightened further, continue working from step .
- If the leak does not stop when the connections are retightened, repair location of leak.
- Do not release refrigerant during piping work for installation and reinstallation.
