   Recovery equipment and cylinders conform to the appropriate standards.

  d)   Pump down refrigerant system, if possible.

  e)   If a vacuum is not possible, make a manifold so that refrigerant can be removed 

from various parts of the system.

  f)   Make sure that cylinder is situated on the scales before recovery takes place.

  g)   Start the recovery machine and operate in accordance with instructions.

  h)   Do not overfill cylinders. (No more than 80% volume liquid charge).

  i)   Do not exceed the maximum working pressure of the cylinder, even temporarily.

  j)   When the cylinders have been filled correctly and the process completed, make 

sure that the cylinders and the equipment are removed from site promptly and 

all isolation valves on the equipment are closed off.

  k)   Recovered refrigerant shall not be charged into another refrigerating system 

unless it has been cleaned and checked.

    Electrostatic charge may accumulate and create a hazardous condition when 

charging or discharging the refrigerant.

   To avoid fire or explosion, dissipate static electricity during transfer by grounding 

and bonding containers and equipment before charging / discharging.

RECOVERY
