The rooftop package units are factory pre-charged with suf

fi

 cient refrigerant. However, there may be a need for charge recovery 

during service and maintenance works. Therefore, some precautions must be taken to ensure optimum and trouble-free system 
operation:
(i)  The system should be throughly vacuumed to ensure no incompressible gas and moisture in the system. 
(ii)  Use a vacuum pump for R22 or R407C exclusively. Using the same vacuum pump for different refrigerants may damage 

the vacuum pump or the unit.

(iii) The refrigerant should never be released directly into the environment.
(iv)  When charging R407C, ensure that only liquid is being withdrawn from the cylinder or can.

Normally, the R407C cylinder or can is being equipped with a dip-pipe for liquid withdrawal. However, if the dip-pipe is 
not available, invert the cylinder or can so as to withdraw liquid from the valve at the bottom.
