Safety information, installation and maintenance For full details see the Installation and Maintenance Instructions (IM-P125-10) supplied with the product. Installation note:

The trap is intended for installation in a vertical line with flow vertically downwards. For tracing applications observe the direction of the red arrow on the trap body. For fixed discharge temperature applications observe the direction of the black arrow on the trap body. This will ensure that the trap is self-draining. When the trap is installed in its fixed discharge temperature mode it must discharge to atmosphere. The trap has not been designed to operate when discharging into a pressurised return main - under such conditions its operation will be erratic and unpredictable. Disposal The product is recyclable. No ecological hazard is anticipated with disposal of this product, providing due care is taken.
