Assembly and disassembly of ARM ProClick actuators
The PrimoBox AZB unit is equipped with ARM ProClick electric actu-
ators. They can be easily disassembled and reassembled.
The ARM ProClick actuators are removed from the valve by pressing
the button on the side of the actuator housing and pulling the actuator
towards you.

To mount the ARM ProClick ac-
tuator on the mixing valve
of the AZB unit, the mixing
valve must be set to "50%
opening", i.e. the center of its valve is exactly halfway between the hot
water inlet and the cold water inlet. Then slide the actuator onto the
mixing valve until the ProClick mechanism locks on it. When mounting
the ProClick actuator on a rotary valve, pay attention to the current
position of the valve cover. The valve stem should be positioned
as in Figure 19, and the actuator position indicator should show half
the scale. If the valve is in a different position, set it manually (using
a flat screwdriver, for example) as shown in Fig-
ure 19. If the indicator on the actuator does not
indicate the center of the scale, switch it to man-
ual operation mode, set the actuator with the al-
len key so that the indicator is in the center of
the
scale.
After
putting
the
actuator
on the valve, switch back to automatic mode.
