Safety information, installation and maintenance This document does not contain sufficient information to install the product safely. See the Installation and Maintenance Instructions supplied with the product. Important Your attention is drawn to Safety Information Leaflet IM-GCM-10. Installation note The injectors are installed at a low level in a tank, ideally along the centre line, and discharging horizontally along the length. Pipework may be routed inside or outside the tank. In all cases, steam supply pipework must be firmly anchored to prevent vibration and stress in the tank wall. We recommend the use of a suitable thread locking compound on all threaded connections. Use the same size pipe as the injector, i.e. 25 mm (1") pipe for IN25M. Pipe sizes for multiple injector installations are as follows:- No. of injectors Type Minimum pipe size 2 IN15 20 mm (0.79") 2 IN40M 65 mm (2.6") 3 IN40M 80 mm (3.1") Allow a minimum of 150 mm (5.9") between the injector(s) and the sides and bottom of the tank, and as much as possible between the injector outlet and the end of the tank. See the IMI for the minimum limits. Space multiple injectors equally across the tank width.
