Screw for load control
Note: The flow switch is factory-calibrated with reference to the minimum cut-out value. To increase this value,
turn the adjustment screw clockwise. The cut-out value must be >= the minimum flow necessary to ensure the
protection of the system. The units without fittings will be supplied with 4 paddles (see drawing palette), which
must be cut according to the pipe. On request they can be supplied to all devices with the T-piece.
CAUTION! In case the unit is used as a minimum flow controller must be placed downstream of a further control
device for the activation of the alarm condition.
Installing the filter
To ensure proper operation of the heat exchanger, it is mandatory to install a filter on the input of the evaporator
near the unit (max 2 meters). The component is required and must be mounted before making circular adequate
flow of water through.
