Page 5: Safety
SAFETY GENERAL SCAI equipment is designed to operate safely when the installation, operation and servicing are performed in accordance with the instructions in this technical manual. For Service Center locations, see the Service section of this manual. SPECIAL NOTICES Three types of special notices -- WARNINGS, CAUTIONS and NOTES are used in this technical manual. - Page 6 Safety WARNINGS AVOID ELECTRIC SHOCK. This equipment must only be connected to a supply mains switch with protective earth. All electrical supply equipment must meet applicable codes and be installed by qualified personnel. If this equipment is modified, appropriate inspection and testing must be conducted to ensure safe use of equipment.
- Page 7 Safety CAUTIONS PRESERVE YOUR WARRANTY. Modification to equipment without the consent of the manufacturer will void the warranty. Specifications require the use of 99.995% pure helium gas. Using a lesser quality of helium can damage the system and void the warranty. AVOID GAS LEAKS.
- Page 8 Safety AVOID EQUIPMENT FAILURE, CONTAMINATION OR A NUISANCE SHUTDOWN. Do not tip the compressor greater than 5 degrees from horizontal, to avoid flowing oil into unwanted places. Use SHIG adsorber P/N F300138A only. Use of non-SHIG spare parts will void the warranty.

Page 11: Introduction
Self-sealing gas couplings allow for easy connection to and disconnection from the rest of the closed-cycle cryogenic refrigeration system. The information in this manual pertains only to the F-20L (low voltage model) Compressor. Other components used to form an operating system are described in separate technical manuals. - Page 12 (This page is intentionally blank.)

Page 13: Principles Of Operation
PRINCIPLES of OPERATION Figure 1 Compressor Flow Diagram Helium discharge temperature switch Atmospheric relief valve Internal relief valve Solenoid valve Pressure gauge Oil discharge temperature switch Water-out temperature switch The compressor continuously draws low-pressure helium from the system return line. It compresses, cools and cleans the gas, then delivers it through the system gas supply line to the cold head. - Page 14 Principles of Operation When helium gas leaves the compressor capsule, the gas contains heat and compressor lubricant. Both must be removed. From the compressor capsule, the hot gas with its entrained oil flows out of the shell and through the bulk oil separator. The gas next flows through one circuit of a three-circuit, water cooled, heat exchanger, where it is cooled.

Page 15: Description
DESCRIPTION Components 50/60 Hz Toggle Switch - This switch on the front electrical panel is used to select different phasing circuits for RDK-101D cold head operations at 50 or 60 Hz. Accessory Receptacle and optional Remote ON/OFF cable - The accessory receptacle on the front electrical panel is a 4-socket connector for supplying remote ON/OFF capability. - Page 16 Description Gas Equalization Solenoid Valve – This solenoid valve opens when the compressor shuts down, allowing helium gas pressure to equalize and prevent oil from moving into low pressure side of compressor. Gas Supply and Return Couplings - Located on the compressor front electrical panel, both are self-sealing, size #8, male bulkhead couplings and are the points of connection for system gas lines.

Installation 2.2 Look through the “peep hole” on the container. View the pressure gauge on the Compressor Unit front panel. The pressure gauge should indicate equalization pressure shown in specification section. 2.3 If the gauge indicates 0 PSIG (0 MPa), the Compressor Unit cannot be used. Contact the nearest SHIG Service Center. - Page 27 Installation 2. Inspect the Tip-N-Tell Sensor on Compressor Unit for Activation. 2.1 Check the Tip-N-Tell sensor mounted on the compressor rear panel. If the Tip-N- Tell sensor shows no mishandling and there is no apparent physical damage, skip Steps 2.2 and 2.3 and proceed to the section Compressor Location. If the Tip-N-Tell sensor indicates mishandling (arrow dot is red), proceed to either Step 2.2 or 2.3: 2.2 The equalization pressure is within specifications:...
