Refilling or Replenishing Air Conditioner System

The jobs for refilling and filling up of air-conditioning system are in principle alike. When refilling, evacuate system first.






Note: Filling requires a supply bottle (1) with refrigerant which is commercially available just like e.g. a supply bottle with oxygen or acetylene gas. In addition. there are small cans (2) (Frigen-Babies), containing approx. 1/2 liter R 12. If hard to obtain, contact one of the specialist companies manufacturing or operating refrigerating units.

Since the refrigerant in the supply bottle is under pressure and liquid. and will flow in the shape of gas when filling the air.conditioning system without a filling cylinder or when refilling, it is recommended (at least when the supply bottle is already partially empty) to place the supply bottle in a water bath of max. 40 CC. If the system is completely empty, the refrigerant can also be filled in liquid form via pressure end upon evacuation. Filling up can be done only in the form of gas with the system switched on.

When filling the system from a refrigerant bottle of 10 kg or 20 kg capacity, a scale with 100 g graduation for the bottle or a filling cylinder will be required.

Attention! If filling up in the form of gas, the supply bottle should always be set up with the lock in upward direction.
