. 

 

 

 

•

 With the DEFROST 

CYCLE highlighted, 
press ENTER to start the 
defrost cycle. 

 

•

 This will automatically 

open the defrost valve. 

 

•

  Open the manual drain 

valve to drain the 
condenser when 
prompted. 

 

•

 Drain the condenser 

after every run and at the 
end of the day. 

 

•

  A defrosted and drained 

condenser will operate 
more efficiently. 

 

•

 Periodically check the 

level of solvent in the 
containers attached to 
the drains. 

 
Screens similar to this are
