■ Air-purging and checking for leakage
Using the vacuum pump
• Use a hexagonal wrench (width across corners: 4 mm).
(1) Connect the gauge manifold and the vacuum pump as illustrated.
(2) Actuate the vacuum pump.
(3) Check that the gauge pointer stabilizes and reads a constant level, close the
gauge manifold, and then stop the vacuum pump.
(4) Open the gas stop valve for about 3 seconds, then quickly close it.
(5) Check the connections marked by
for gas leaks. To do this, apply soapsuds
to the connections and check carefully.
After checking, completely wipe off the soapsuds.
(6) After checking for gas leaks, completely open the liquid and gas stop valves.
(7) Disconnect the gauge manifold and the vacuum pump.
• For flare nut connections
- First, remove the smaller flare nut from the liquid pipe. Connect the
pipes, then fully tighten the flare nut as shown.
- Next, remove the larger flare nut from the gas pipe. Connect the pipes,
then fully tighten the flare nut as shown.
• Be sure to use both a spanner
and a torque wrench together,
as shown in the drawing, when
connecting pipes to or
disconnecting them from the
unit.
• When connecting the flare nut,
coat both the inside and
outside with refrigerent
machine oil. Then, tighten it 3
or 4 turns by hand before
tightening it firmly.
• Refer to Table 1 to determine
the power tightening torque.
(Overtightening may damage
the flare and cause leaks.)
• Check the pipe connections for
gas leaks.
• Install the insulation as shown in the drawing above.
(Install the insulation for the fittings attached to the pipe fixing plate.)
• Wrap the sealing pad 4 around only the union of the gas piping (over the
insulation for fitting 2 ).
Coat here with
refrigerating
machine oil.
