INSTALLATION OF OUTDOOR UNIT (Cont.)
1. Check that the pipeline connections have
been properly connected. Remove the
charging port cap, then connect the
manifold gauge and the vacuum pump to
the charging valve by the service hoses,
(shown in drawing).
2.Open the valve on the low pressure side
of the manifold gauge, then run the
vacuum pump. Vacuum the indoor unit
and the connecting pipes until the
pressure in them lowers to below
1.5mmGH (the operation time for this
should be about 10 minutes).
When the desired vacuum level is reached,
close the low pressure valve on the
manifold, then stop the vacuum pump.
3.Disconnect the service hoses, then fit
the cap to the charging valve.
4.Remove the blank caps, then fully open
the spindles on the 2-way and 3-way
valves with a service valve wrench.
5. Tighten the blank caps on the 2-way
and 3-way valves, according to the
previous torque Table 1.
