Cold-heat air, 3800fg, does not raise pressure.
The two valves open completely the pressure is kept below zero, corresponding to the vacuum, adding the refrigerant the vacuum does not break, when the equipment is turned on either, the equipment does not have gas, so the load that tries to carry it out. The evaporator does not change from room temperature, when adding a small jet of gas of about 5 seconds it is possible to cool the high pipe, so it occurs to me that an obstruction does not allow the gas to complete the circuit.
OK, I BELIEVE THAT I UNDERSTANDED YOU, I EXPLAIN HOW I LOAD IT WHAT I WAS TAUGHT AT SCHOOL (R22), TURN ON THE EQUIPMENT IN COLD MODE ONE TIMES IN OPERATION, OPEN THE GARRAFA AND LEAVE GAS FOR A MINUTE WITHOUT MISSING THE 60 PSI WHILE GAS IS ENTERING, CLOSE THE GARRAFA, THE PRESSURE WILL LOWER LEAVES A SECONDS TO BE STABILIZED TO REPETIS HOW MANY TIMES IT WILL BE NEEDED UNTIL REACHING A WORK PRESSURE BETWEEN 62 AND 65 PSI, YOU WILL KNOW THAT IT FREEZES COMPLETE THE HIGH PIPE IS NORMAL THAT, ONE ONCE THAT BEGINS TO FILL HIMSELF ONLY, GIVE IT WITH CONFIDENCE.
