Cooling water

Requirements
The closed cooling-water circuit must be filled with
approximately 350 l of potable water. The water is filled in the
tank automatically by the re-fill valve on the side of the tank.
Water refill of the tank is automatically controlled during normal
operation.
Ensuring anti-freeze protection
If ambient temperatures fall below +5 °C use approximately 33%
of anti-freeze depending on manufacturer specification in
relation to wanted temperature protection. ABB recommends
Glycol as anti-freeze. Anti-freeze with anti-corrosive additive is
not permitted. A tank heater is provided as an option to lower
the risk of damage to the cooling system during cold weather.
Instructions
1. Remove the probe from the hot process to the service
position S2 in manual operation
2. Close the water supply of potable water to the water tank
3. Open the water tank top cover to a side to allow anti-freeze
to be filled in tank
4. Release approximately 33% of the water tank capacity
5. Add the 33% of anti-freeze to the water tank
6. Close the water tank top cover
7. Open the water supply of cooling water to the tank
8. Check cooling water circuit for leaks. Remedy any leaks
before continuing with start-up.
9. Reset and make sure that all alarms and maintenance
requests are cleared
10. Introduce the probe to measuring position S3 and enter
probe gas sampling system into Automatic Mode

Air supply

Requirements
The compressed-air must meet the following minimum
requirements:
Dew point
0°C (below 0°C make sure that the compressed-air supply
cannot freeze).
Pressure
Minimum 5 bar
Maximum 8 bar
Default operating pressure at 6 bar
Consumption
3 m /h
3
Quality
The compressed-air must be free of dirt and oil/water
droplets. Check the quality of the compressed air at the
connection to the customer-side compressed-air system
using a white cloth. If you observe any oil, moisture or other
impurities, abort start-up and do not continue until these
residues have been permanently eliminated.
