Safety Warnings
Review the safety warnings in Section
before beginning any installation activities.

Installation Steps
5.2.1
Unpacking and Inspection
Once the equipment is received, inspect the exterior of the shipping carton for any signs of damage. Report any damage to
the shipping company immediately.
In addition, at least two “Tip-n-Tell” or “TiltWatch” labels are mounted on the exterior of the shipping carton. Inspect
these labels carefully before accepting the shipment. Any sign that the package has been mishandled during transit may
indicate that the compressor may be damaged due to oil migration within the system. This could cause the unit to
overheat and ultimately fail after a short period of operation. The compressor must be returned to the factory for service.
Report the mishandling of the package and file a damage claim with the shipping company immediately. Failure to do so
will void the warranty on the compressor. Please also contact Trillium US Inc. Technical Support using the contact
information found in Section 2.2.
Remove the straps and packaging materials on the compressor unit, then lift or roll the unit out of the carton carefully.
Inspect the exterior of the unit. If any damage is observed, inform the shipping company.
Keep the original packaging
materials in case the unit needs to be returned to the factory for service or other reasons.
Most shipping companies have a certain grace period for reporting damages due to shipping in order to process the
insurance information in a timely manner. Therefore, it is highly recommended that shipping carton be opened and the
unit inspected whether or not it will be put into operation right away.
Caution:
When transporting or storing the compressor unit, make certain it is not tilted by more than 45 degrees
to avoid the unit been tipped over.
5.2.2
Mounting the Compressor
It is highly recommended that the compressor unit be installed on a level and steady surface.
If the unit must be installed in a tilted manner, the maximum tilting angle is 10 degrees. Tilting the unit more than this
maximum allowable angle could result in damage and contamination in the system and may void the warranty on the unit.
5.2.3
Preparing the Compressor for Operation
1.
Check the voltage of the power source before connecting the main power cable to a suitable connector or
disconnect box, making sure that the compressor switch is off.
2.
For water-cooled Model 125 units, connect the cooling water:
a.
Typical municipal drinking water is acceptable; however, a closed loop chilled water source is
recommended.
b.
0.4 to 0.5 GPM (1.5 – 1.9 liters/min) is required to achieve a maximum discharge temperature of 100°F
(38°C) (with 80°F (26.7°C) considered ideal)
c.
Maximum inlet water pressure should not exceed 150 PSIG (10.3 Bar) (with less than 100 PSIG (6.9 Bar)
considered ideal).
3.
For air-cooled Model 125 units, make sure the front and rear grills have at least 12” (305 mm) of clearance from
the nearest objects.
4.
Verify that helium pressure is between 190 ± 5 PSIG (13.1 ± .35). If pressure is low, refer to Section 8.4.1 for
charging procedures.
5.
Start the compressor and run for about 15 minutes to stabilize the compressor oil inventory.
6.
The compressor is now ready to be connected to the cryopump.
