Refrigerant charging process in case of exceeding the recommended limit
– Charge the liquid refrigerant into the condenser, by means of a “T” piece
(fi g. 1)
, or through the fi lter
(fi g. 2)
.
– Charge in different steps through the compressor service tube, each step no more than 350 grams. The compres-
sor must be switched on between each step in order to move the liquid to the condenser.
– Use an intermediate charging cylinder. The refrigerant is weighted in liquid phase from the charging station and
injected into this intermediate cylinder. Part of it is charged into the compressor in liquid phase and the compressor
is switched on (never start the compressor while the system is under vacuum). The compressor will suction the rest
of the charge remaining in the intermediate cylinder in vapor phase.
