FastCCD chiller¶
The CRYOMECH CP830 cryo-chiller is located near the FastCCD electronics rack. Below are intructions to start ip up and shut it down.
Start up:¶
 |
make sure that the power is connected and the interlock allows the chiller operation (red LED on front panel under interlock connector is on) | |
 |
check that the two Helium lines are connected both to the chiller body and to the chiller head (on the beamline) | |
|
check that the motor power cord is connected both to the chiller body and to the chiller head | |
 |
Turn the cooling water outflow red valve (right of the green valve marked “FastCCD”) anti-clockwise all the way | |
|
Open the cooling water inflow green valve marked “FastCCD” | |
|
close the circuit breaker on the chiller front panel | |
|
press the large green button on the front panel, the button will lighten up | |
| the chiller should make a regular (~1Hz) loud ‘chick’ noise | ||
| the FastCCD temperature shoud start decreasing after ~1/2 hour |
Potential DANGER with wall water line:¶
Never close the cooling water outflow red valve while leaving the water cooling inflow green valve open, as this may lead to a water leak in the chiller.
