External Chiller Use
For liquid-cooled cameras, an external chiller provides a vibration-free method of heat
removal. Perform the following procedure to connect an external chiller to a
liquid-cooled Lansis camera:
NOTE:
For specific configuration information, refer to the
manufacturer-supplied documentation included with the
external chiller.
1. Verify the camera and the circulator power switches are turned off.
2. Verify the chiller is positioned a minimum of 6 inches (150 mm) below the Lansis
camera. The vertical distance should not exceed 10 feet (3 m).
Typically, the camera is at table height and the circulator is on the floor.
3. Using the supplied cooling hoses, connect the two coolant ports on the external
chiller to the two coolant ports on Lansis.
CAUTION!
!
Verify there are no kinks in hoses that may impede coolant
flow. Lack of sufficient flow can seriously harm the detector.
Any resulting damage is not covered under warranty.
NOTE:
Although there are no dedicated IN or OUT coolant ports on
a Lansis camera, Teledyne Princeton Instruments
recommends that the lower port (depending on the
camera’s physical orientation,) be used for the coolant inlet
for best efficiency.
NOTE:
Damage caused by water leaking into the Lansis voids the
warranty.
4. Verify that the reservoir on the external chiller contains sufficient coolant as
specified by it manufacturer. If additional coolant is required, use a 50:50 mixture of
water and ethylene glycol based commercial antifreeze to add sufficient coolant.
5. Replace the reservoir cap.
6. Plug the external circulator into a 100-240 V
AC
, 47-63 Hz power source.
7. Turn the chiller on.
CAUTION!
!
When configuring an external chiller, adhere to the
following:
•
Coolant flow-rate should be at least 3 1/min (0.8
gpm)
•
Coolant pressure should never exceed 137kPa (20
psi).
•
Never set the circulator temperature below the dew
point.
