Manual for SCC-C

Warranty Information
None
Normal Operation: The SCC-C sample gas cooler cools sample gas and separates/removes condensate. It is not for use in hazardous areas unless it features stainless-steel heat exchangers for flammable gases.
Installation: Install close to the gas analyzer with adequate air circulation, protected from adverse environmental conditions. Connect sample gas and condensate pipes, and electrical lines.
Start-Up: Activate power supply after a 15-minute lead time. Sample gas supply should only start when the outlet temperature is below +6 °C.
Maintenance: Regular cleaning of condenser fins and potential replacement of peristaltic pump hoses and rollers are described. Heat exchangers can be removed for cleaning.
Shutdown: Disconnect power and gas supplies, purge paths with inert gas, and tighten connections.

Troubleshooting and error codes
| Problem | Cause | Remedy |
|---|---|---|
| Condensate in the Sample Gas Outlet | Ambient temperature < 5 °C | • Heat the downstream assemblies. |
| Sample gas cooler overloaded | • Ensure sample gas inlet conditions (see page 7) and operating specifications (see page 27) are followed. | |
| Defective peristaltic pump | • Replace the peristaltic pump. | |
| Defective pump hose | • Replace hose (see page 16). | |
| Cooling performance inadequate although sample gas cooler not overloaded | • Provide adequate cooling air flow. | |
| • The fan should operate. | ||
| • Maintain the minimum clearance with respect to adjacent units or walls (see page 8). | ||
| • Clean condenser fins (see page 20). | ||
| Compressor motor breaker tripped | • Eliminate the thermal overload caused by the sample gas flow or excessive ambient temperature. | |
| • Clean condenser fins (see page 20). | ||
| • Ensure sample gas inlet conditions (see page 7) and operating specifications (see page 27) are followed. | ||
| • Allow the compressor to cool before the next run. | ||
| Sample Gas Flow Blocked | Sample gas paths contaminated | • Contamination can result from the failure to remove dust or sublimates. Ensure dust is removed before the sample gas enters the sample gas cooler; eliminate sublimates prior to this point. |
| • Clean the sample gas lines and cooling system; consider the effects of corrosion and reduced service life when using chemical cleaners and flush with an inert gas in order to avoid any cleaning agent influence on measurement results. | ||
| Inaccurate Temperature Indication | Defective temperature controller | • Replace temperature controller. |
| Refrigerant escaping | • Send the sample gas cooler to the service department for service. | |
| Defective Sample Gas Cooler | Power supply disconnected | • Reconnect the sample gas cooler power supply. |
| Defective motor breaker or winding, i.e. the compressor motor is not running | • Measure the electrical resistance of the motor winding (guide value is approx. 40 Ω). | |
| • If the difference is considerable (with measuring circuit open or short-circuited), then the motor breaker should be replaced. | ||
| • If the motor winding is defective, send the sample gas cooler to the service department for repair. |
