We recommend to install the PRE horizontally or vertically with coil at the lower end.

If installed vertically upwards please consider changes of minimal regulated

pressure! Pay attention that no air is in the system. In some applications the coil-

support has to be bleed by the screw at the support. Line T has to be connected

directly to tank. Every counter-pressure on line T has to be added to the regulated

pressure. Maximal permitted counter-pressure at T: 2 bar.

The fixation of the valve will be done by screws or tension rods on a plane surface

which surface finish is equal or higher than the valves finish. If the surface finish is

not as specified above, leakages may occur.
