cooling water flow if measurement is stopped and T

of sample gas

may be higher than the cooling water temperature.

Connecting the Cooling Liquid

Figure 15 DMP501 Back Panel, Connectors for Cooling

Liquid

The following numbers refer to Figure 15 above:

1 = Water In (WI)

2 = Water Out (WO)

1. Remove the Swagelok fittings from Water In (WI) and Water

Out (WO) connections.

2. Attach the tubes (diameter of 8 mm) to the Swagelok fittings

(diameter of 8 mm or 5/16"). Plastic tubes are recommended.

3. Connect the water inflow tubing to the connector WI. And

similarly the water outflow tubing to connector WO. Reverse

water flow can be used as well.

4. Replace the Swagelok fittings to the back panel connectors.

5. Let the water flow with the flow rate of 5...20 l/min, temperature

of water shall be <+15 ºC (50 ºF). Check for leaks and tighten if

necessary.

Once the water tube connections have been tightened, the water tubing

should be disconnected from the Swagelok fittings.
