Security information, installation and maintenance

For detailed information, refer to the Installation and Maintenance Guide (IM-P181-03) supplied with the product. It is best to install horizontally with a section of drop pipe in front of the trap. The BTD52L can also be installed vertically where it is freezing or where horizontal installation is not possible, but this may affect its service life. Shut-off valves should be provided at the front and rear of the trap for ease of maintenance and replacement. If the trap discharges into a closed recovery system, a check valve should be provided downstream of the trap to prevent fluid return.
