Description
After finishing the wall or floor, remove the cover plate and simply screw the vacuum contact into the pre-mounted screw holes in the flush-mounted box. The vacuum contact – inlet valves can be mounted either with the hinge at the top or at the bottom.
Now also connect the 24-volt signal cable. Use only the original flat screws provided. It is important that on non-level surfaces (e.g., clean masonry), the vacuum contact is not warped by screws that are too tight. Hand-tightening prevents unnecessary leakage of suction.
