Compressor Unit Safety Instructions
Read this manual and follow these safety guidelines before installing, operating, or
servicing the compressor unit.
Our Cryo-U
®
cryopump and Super trap refrigerator systems make a refrigeration cycle by
circulating high pressure helium gas. Filling helium gas more than the defined amount
does not improve refrigeration capacity
appreciably. Instead, if excessive helium gas is
filled and pressure becomes higher than the defined value, gas will release from the safety
valve and its sheet may become clogged with dirt. This may even cause a leak as well as
overloading of the compressor motor.
Never charge helium gas more than specified in Table 1-5.
When charging helium gas or performing helium line decontamination, please read the
“Maintenance” section carefully and follow the instruction.
Please supply the equipments (regulators, charging hoses, adopters, etc.) that can be used
at the pressure of 2.0MPaG or above.
Switching between ON and OFF should be less than 6 times per hour, and ON and/or OFF
condition should be maintained longer than 3 minutes.
Frequent starting/stopping shortens the insulation life of the compressor motor and may
cause a failure of the product. When operating multiple refrigerators, the refrigerator
motors must be started / stopped into 6 times or less per hour also.
Do not turn on and off the compressor to control the temperature of super trap.
Please contact us when controlling the temperature of super trap is required.
1. Do not Charge Compressor with Excessive Helium
2. Adding Helium Gas and Charging Equipments
3. Do Not Switch between ON and OFF Frequently
