Open the Valve at the lower part of charge cylinder.
When charging
HFC-134a
to
inside Cylinder
Charge, the Valve at top Cylinder Charge must be
small open to let out HFC-134a.
Find the scale which is the nearest to pressure
reading at the cylinder gauge. And place the scale in
the center of the glass tube.
Confirm the set amount of glass to be charged in the
refrigerator be refering to the wiring diagram or the
name plate of the unit. And put a mark at the
division indicating the amount of HFC-134a which
should be left in the charge cylinder glass tube after
the set amount of gas is charged.
When HFC-134a cylinder is put upside down, as refrigerant discharge as liquid, never loosen the
valve at cylinder charge and the adaptor charge.
Do not touch gaseous Refrigerant directly, cause burn skin by "freezer burn" due to low temperature.
Slowly open the valve on the lower sie of cylinder
and charge the unit with HFC-134a.
When the set amount is amount charge, close the valve. After liquid surface in the glass tube is
stabilized, open the valve a little to charge the gas slowly.
Close the valve at Cylinder charge and adaptor charge when charging refrigerant is finished.
When to disconnect the charge hose, plce HFC-134a cylinder at proper position and loosen the
charge adaptor to let liquid escape.
When refrigerant discharge completely, close the valve of HFC-134a cylinder.
Put the HFC-134a cylinder upside down (so that
HFC-134a can be put in the Charge Cylinder as
liquid).
Before vacuum pumping process, it should charging the refrigerant from Cylinder HFC-134a to inside
of Cylinder Charge.
Fit the Adaptor Charge at Cylinder HFC-134a.
Connect the Valve at bottom side of Cylinder Charge
and Adaptor Charge from Cylinder HFC-134a with
Charge Hose.
Open the HFC-134a Valve and slack the Charge
Hose at Cylinder Charge to let out the air, then
connect the Charge hose firmly.
