Sea Frost BG 2000 Installation, Tube Handling, Tube Cutting, Tube Bending

INSTALLATION

Installer's care should be stressed. No matter how good SEA FROST equipment is, its performance and life are in the hands of the installer. To insure your work:

1.Read this manual.

2.Reread any aspect you don't understand.

3.Follow Swagelok fitting instructions carefully.

4.Spend enough time leak-checking to be sure there are no leaks.

5.Thanks from all of us who have to guarantee your work.

There are two contaminants that will give you problems in any refrigeration system. They are WATER and DIRT. Moisture is always present and cannot be eliminated, water in this case refers to puddles and drops. Dirt is any solid. The installer's habits will be most important in ensuring a trouble-free start-up. We have added a large receiver filter dryer (RFD) to take care of all dirt and moisture that might get into the system during a careful installation. Moisture in the system is boiled off when the system is evacuated, or it is captured in the desiccant. There is a screen in the expansion valve to prevent dirt from plugging it.

Excess moisture that the RFD can't handle will plug the expansion valve with ice. This ice stops the cycle. The only cure is to discharge the refrigerant, replace the RFD, re- evacuate the system, and recharge it. This remedy takes time and is somewhat costly. Keep the system clean when installing it to save time for something more fun.

TUBE HANDLING

Installation is quite simple. All the copper tube comes to you with the ends capped. Any routing of the tube must be done with the tube either taped or capped. Cap both tube ends after each cut. (Spare caps have been included). Work with only one line at a time, and only uncap one end at a time.

TUBE CUTTING

Use only a tube cutter; hacksawing or any other method will introduce chips to the system and also distort the tube, making connections difficult and leak-prone. A miniature cutter is essential for this work. CUT SLOWLY to avoid a ridge on the inside of the tube. We do not recommend reaming or dressing the cut, as it is very easy to get chips of copper in the system, which may cause trouble.

TUBE BENDING

Make all but the long sweep bends with a spring bender; one kink and the line must be rerun. Don't add any more fittings than are absolutely necessary. Route all lines in such a way that they are most direct but out of the way. Again, keep everything sealed until you are ready to make that connection.
