WARNING: Explosion or Rupture Hazard. A relief valve must be installed to prevent pressure in excess of local code requirement or maximum working pressure designated in the Product Manual, whichever is less. Do not expose Series CRS Coalescing Removal Separator to freezing temperatures or temperatures in excess of 450°F. Failure to properly size the Product or follow these instructions may result in excessive strain on the system and may lead to Product failure, serious or fatal personal injury, leakage, and/or property damage. - Page 3 WARNING: System fluid under pressure and/or at high temperatures can be very hazardous. Before servicing, reduce system pressure to zero or isolate the vessel from the system. Allow system to cool below 100°F and above 35°F. Failure to follow this instruction may result in serious personal injury and/or property damage. B.
- Page 4 CAUTION: Use unit lifting lugs only to lift unit as shipped from factory. Unit must be empty and disconnected from pipe, and other restraints. Use proper rigging procedures. Failure to follow these instructions could result in injury or property damage. Be aware of water weight in the separator and connected piping when installing your system.
- Page 5 Operating Instructions fig. 3 - Series CRS Operation 1. The system water contains air bubbles, entrained air, and dirt particles. 2. Large air bubbles quickly rise to the top of the vessel and into the vent. Micro-bubbles coalesce and form larger bubbles.
- Page 6 The coalescing medium in the Series CRS separator may need to be cleaned periodically. This is true during the initial start-up period. The need to clean the coalescing medium will be evidenced by a high pressure drop across the separator or by pump cavitation problems. To clean the medium: 1.
- Page 7 5. Once the cover has been reassembled to the Series CRS separator and the bolts have been appropriately tightened, close the blowdown valve at the bottom of the separator and open the isolation valves to return the separator to normal operation. Service Instructions - Accessories The Series CRS separator may have optional accessories assembled at the factory, or by the installer at the job site.
- Page 8 7. Properly assembled separator components will immediately seal to moderate pressure (100 PSI or less). For maximum pressure resistance, allow the Loctite 567 or RectorSeal No. 5 thread sealant to cure for 24 hours. PTFE tape typically does not require curing to achieve maximum pressure resistance. NOTICE: Over application of torque may cause damage to the Separator or accessory component.
