Sea Frost DC 5000 Planning, Positioning The Rfd, Helpful Tools, Line Connection Plan

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.
