After some futzing around with the chiller, we have come to the tentative conclusion that the refrigeration unit is not working. Steve called facilities to try to get them to recharge the refrigerant (R-404a) tomorrow, and we're also calling around for a spare chiller somewhere in the project (without luck so far).

The repair man thinks it's a bad start capacitor, which is 240uF at 120V. Steve has ordered a new one which should be here tomorrow, and with luck we'll have lasing by tomorrow afternoon. |
