Select an appropriate location for the Pressure boosting unit.

    Note that the connecting tubes should be loose and not bent. The free sections of the tubes should be fixed so that they cannot be damaged by other objects. The water filter must be placed at a distance or isolated from any heat sources (kitchen ovens, boilers, hot water supply pipes, dishwashers or washing machines, etc.) and placed in a place that prevents water from entering the housing of the Pressure boosting unit and the power supply unit.

    Connecting the Tubes

    Remove the stopping clip from under the plastic sleeve, insert the pre-wetted end of the tube into the sleeve of the fitting until it stops at a depth of about 15 mm, and insert the clip. Check the strength of the fastening of the tube: at a force of 8-10 kgf, the tube should not be pulled out.

    Disconnecting the Tubes
