Cooling Water Configuration 3
Fluid Circulator Supplying Peltier, Mains Water Supplying Upper Heated Plate
Alternative configurations, not shown here, are for the Upper Heated Plate and Peltier to be supplied by sepa-
rate fluid circulators, and for the Upper Heated Plate to be supplied by a fluid circulator, the Peltier by mains
water. The non-return valve is not required for either of these configurations.
Connecting the Cooling Control Unit
This unit may be free standing, or wall mounted using the clearance holes on top of the unit (see Figure 7.11 to
the right below).
1. Connect the air supply to the GAS IN port on the CCU
using the 8-mm outer diameter tubing (white). If it is
necessary to split the air line to provide a source for
both the instrument air bearing and the CCU, this
should be done upstream of the instrument filter
regulator system.
2. Connect the water supply to the LIQUID IN port on the
CCU using the 6-mm outer diameter tubing (blue). If
mains water is used as the supply, then the non-return
valve (see Figure 7.9 below) should be placed in the line
upstream of the CCU.
Important: Note the direction of flow through this
valve.
Important: Notez la direction d’écoulement à
travers de la valve.
