The  scroll  compressor  achieves  low  suc-
tion  pressure very quickly.  Do  not  use  the 
compressor  to  evacuate  the  system  below 
0 psig. Never operate the compressor with 
the  suction  or  discharge  service  valves 
closed  (frontseated).  Internal  damage  will 
result  from  operating  the  compressor  in  a 
deep vacuum. 
 
Do  not  direct  water  or  steam  into  the  gen-
erator openings. Do not allow any soap and 
water solutions to enter the generator. 
 
Under no circumstances should anyone at-
tempt  to  repair  the  Logic  or  Display

these  components,  contact  your  nearest
