19.When filling a refrigerant cylinder, never com-

pletely fill it. Always leave space for expansion. If

the cylinder was completely filled and the tem-

peratures increases, the hydraulic pressure with

its tremendous force would result to cylinder

bursting accidents.

One of the most important requirements when filling

the air conditioning system is to use clean refriger-

ant. Any foreign substances – including air, moisture

and dirt - in the air conditioning circuit influence tem-

perature and pressure of the system. This will have

an adverse effect on the operation of the system. In

addition, these foreign substances can cause defects

such as failure of the compressor due to excessive

wear.
