Storage Procedure

IGRINS should remain cold while being stored at McDonald

1. After removing IGRINS from the telescope and placing in the proper place on the dome floor, connect the A/B/C cables for the temperature sensors.
2. Attach the pressure gauge cable.
3. Reconnect the coldhead power and helium lines, and start the helium compressor. 
4. The fiber optic network cable must be connected so the instrument can be monitored remotely.
5. Do not:  
   1. Connect detector power and USB unless requested.
   2. Press the power button on the three black Windows computers in the electronics cabinet.
6. Flip the power switch on the back of the electronics rack and then press the red button inside the rack, at the very top.
7. The first four buttons on the EATON power supply (ThAr,THL,UNe, Motor) need to be turned off.
8. The Lakeshore heaters should be set to normal operating temperatures.   
9. Housekeeping Package should be started and verified by looking at the webpage: https://igrins-hk.firebaseapp.com
10.  Note:
    1. Large jolts and impacts can harm the optics and the detectors are sensitive to power fluctuations.        
    2. As part of Fduty please ensure that heaters are operating normally, that the dewar pressure is lower than 1E-7 torr, and that the CTI Coldhead is making the appropriate maraca noises.
