Installation
2. Inspect the following:
2.1 Check the Tip-N-Tell Sensor mounted on the compressor. (Some compressors also
have a Tip-N-Tell mounted on the outside of the shipping container.) If the Tip-N-
Tell Sensor shows no mishandling and there is no apparent physical damage,
proceed to the sections Compressor Position and Compressor Checkout.
If the Tip-N-Tell sensor indicates mishandling (arrow point is blue), read the
equalization pressure. Proceed to either Step 2.2 or 2.3.
2.2 The equalization pressure is within the specifications. Refer to the Compressor
manual.
ELECTRIC SHOCK. All electrical supply equipment must meet applicable codes
and be installed by qualified personnel.
ELECTRIC SHOCK. Permit only qualified electrical technicians to open
electrical enclosures, to perform electrical checks or to perform tests with the
power supply connected and wiring exposed. Failure to observe this warning can
result in serious injury or death.
AVOID CONTAMINATION. When checking the compressor for shipping
damage, do not connect gas lines and cryopump. The components may become
contaminated with compressor oil.
Connect power and water to the compressor. See the next sections Compressor
Positioning and Compressor Checkout. Test run the compressor for two (2) hours
minimum. If there are no problems during this time, stop the compressor and
proceed to assemble the system.
If the compressor shuts down during the two (2) hour test, contact the nearest SCAI
Service Center.
2.3 If the equalization pressure is outside the specified range or there is physical
damage to the compressor housing or the compressor has been on its side or
upside down for an extended period of time (more than one hour), contact the
nearest SCAI Service Center.
If the compressor has been momentarily tipped (less than one hour) and the
equalization pressure is with specifications, allow it to stand upright for two hours
before running the two-hour test in Step 2.2.
3. Remove the plastic wrapper from the cryopump.
4. Remove the cover from the mounting flange.
