Installation and Maintenance

Installation Requirements

1. The product must be installed on horizontal pipework with the drain outlet pointing directly downward to ensure proper drainage of separated liquid
2. A suitable steam trap must be connected to the drain outlet to ensure rapid liquid discharge
3. For detailed installation steps, refer to the Installation and Maintenance Instructions (IM-P023-55) provided with the product

Caution

The drain outlet must be connected to a steam trap to ensure timely discharge of separated liquid, otherwise separation efficiency will be affected.
