I guess that I would be wondering if you are vacuuming and charging the unit correctly....it would seem that maybe the unit has an incorrect charge...
have you vacuumed the entire unit and carefully weighed in the charge???

Gas leak is due to loose valve or cracked gas pipe.Check out both.Also reconnect the settings as follows:--
Connect each assembly pipe to the appropriate valve
on the outdoor unit and tighten the flare nut.
Connect the charging hose of low pressure side of
manifold gauge to the packed valve having a service
Open the valve of the low pressure side of
manifold gauge counter-clockwise.
Purge the air from the system using vacuum pump
for about 20 minutes.
– Make sure that pressure gauge show
-14.5psi(-0.1MPa, -76cmHg) after about 20 minutes.
– This procedure is very important in order to avoid
– Turn off the vacuum pump.
– Close the valve of the low pressure side of
manifold gauge clockwise.
– Remove the hose of the low pressure side
of manifold gauge.
Set valve cork of both liquid side and gas side of
packed valve to the open position.
Mount the valve stem nuts and the service port cap
to the valve, and tighten them at the torque of
183kgf•cm with a torque wrench.
Check for gas leakage.
- At this time, especially check for gas leakage from
the 3 way valve’s stem nuts, and from the service
