Safety information, installation and maintenance For full details see the Installation and Maintenance Instructions (IM-P123-13) supplied with the product. Installation note:
The AV45 is designed for installation with the element in a horizontal plane with the cover at the top. Positioned at the highest point of the main, or plant where air collects. For maximum air removal, the discharge should be as free as possible or piped to a safe location. When welding the trap into the line there is no need to remove the element providing the welding is done by the electric arc method. For ease and maintenance consideration should be given to fitting isolation valves upstream and downstream of the air vent. The air vent should not be insulated. Disposal The product is recyclable. No ecological hazard is anticipated with disposal of this product providing care is taken.
