OPERATION OF THE VALVE

1. Position of the knob with scale

Once the valve has been correctly set and the scale was selected, position "0" will mean that the valve is fully closed

(hot water supply is closed) and position "10" will mean the valve is fully open (hot water supply is open). Any other

position on the scale will indicate the percentage of valve opening (e.g. position "4" will mean the valve is 40% open).

2. Position of closing element

The closing element is located on the opposite side of the flattening on the adapter. To check the correct operation

of the valve, remove the knob from the adapter and check the location of the flattening.

3. Installation of the ProClick electric actuator or controller

Under the knob of the ARV Vario ProClick valve, there is always an adapter for mounting the ProClick electric actuator

or the controller. With the ProClick mounting system (fig. 5), simply remove the knob and blue limiting ring from

the valve and then slide the ProClick actuator or controller into position until the mounting mechanism engages

on the valve. When using the valve in the mixing function, ACT/ARC ProClick controller or a 3-point actuator must

be used (e.g. AFRISO ARM 343 ProClick). In order to automate the valve in the switching function, a 2-point actuator

(e.g. AFRISO ARM 703 ProClick) must be used.

APPROVALS AND CERTIFICATES

ARV Vario ProClick 3-way rotary mixing valves are subject to the Pressure Directive 2014/ 6 8/EU and are not CE marked

in accordance with Article 4.3 (recognised engineering practice).

The products have been marked with the B construction mark, in accordance with the regulations in force in Poland.
