 PLANNING 
 
1. Keep tube runs as short as possible. The suction (return) line should be as direct 
as possible with a minimum number of bends. 
 
2. Tape the 1/4" line and the 1/2" line together in the section between the V/U and 
the DC 5000.  This is for thermal exchange (sub cooling). 
 
 
 
POSITIONING THE RFD 
 
•  The RFD is fitted with a sight glass.  This glass must be visible for charging 
and servicing the system.  It can be viewed from the top at up to a 45-degree 
angle but not from the bottom or side.  A mirror installed above the glass is one 
way of saving a poorly planned installation.  Avoid this if possible.  Be sure the 
sight glass is easily visible! 
 
•  Observe the inlet/outlet on RFD when mounting it.  The glass is offset toward the 
outlet.  
 
•  The RFD should be unpacked and installed only after all the lines are run and all 
other fittings are made.   
 
HELPFUL TOOLS 
 
•  Coil spring-type tube benders are available for 3/8"-1/2" O.D. tube.  These springs 
are slid over the tube.  The bend is formed in the spring, and then the spring is 
removed by unscrewing. 
 
•  Lever benders for each size tube.  Lever benders will make the tightest possible 
bend without distorting the tube.  
 
•  Mini tube cutter:  "IMP" by Gould Imperial requires less than 1 1/2" radius 
clearance for the cut.  This is essential to trim the plate tubes. 
 
 
LINE CONNECTION PLAN 
 
Run 1/4" copper tube from the DC 5000 to the RFD.  From the RFD 1/4" copper tube 
continues to the V/U.   Run 1/2" copper tube from the large connection on the V/U to the 
DC 5000.  The two lines should be combined with tape and insulated together. See 
Insulating the Lines.
