Operation 

6.1

 

Standard liquid/vapor recovery procedure

 

1.

 

Make sure this recovery machine is in good operating 
condition. 

2.

 

Make sure all connections are correct and tight . 

3.

 

Open the liquid port of the storage tank. 

4.

 

Make sure the MODE valve is set on RECOVER. 

5.

 

Open the output port of the recovery machine. 

6.

 

Open  the  liquid  port  on  your  manifold  gauge  set; 
opening the liquid port will remove the liquid from the 
system  first.  After  the  liquid  has  been  removed,  open 
the  manifold  vapor  port  to  finish  evacuating  the 
system. 

7.

 

Connect  the  recovery  unit  to  an  appropriate  outlet. 
(See the nameplate on the machine) Switch the power 
switch to the ON position to start the compressor. 

8.

 

Slowly open the input port on the machine. 
A)  If  the  compressor  starts  to  knock,  slowly  throttle 
back the input valve until the knocking stops. 
B)  If  the  input  valve  was  throttled  back,  it  should  be 
fully  opened  once  the  liquid  has  been  removed  from 
the system (the manifold gauge set vapor port should 
also be opened at this time). 

9.

 

Run until desired vacuum is achieved. 
A)  Close  the  manifold  gauge  sets  vapor  and  liquid 
ports. 
B) Turn off the machine. 
C)  Close  the  unit's  input  port  and  proceed  with  the 
SELF–PURGE PROCEDURE on the next page.
