Defensor ABS2 Installation and Operating Instructions

4.3 Water connections
• Drill the 12 mm diameter holes and insert the supplied screw anchors.
• Screw in the screws until the heads are 8 mm away from the wall
surface.
• Hang the base unit on the screws and then tighten them completely. Use
the spirit level again to check horizontal alignment.
• Insert filter unit(s) (FU1 or FU2) from below in the retainers of the base
unit. Swing the filter unit(s) upwards and fasten with retaining latches.
Note: Since the filter units are square, their orientation is immaterial.
• Install the insert from the base unit from above (observe orientation).
• Carefully insert the atomizer unit into the base unit from above and turn
it to the desired position.
Important! Make sure that the electric cable of the atomizing unit is not
pinched.
• AU90: Mount the directing hood and then the aerosol discharge hood on
the atomizer unit. Also mount the ring filter (if used).
• Plug in the electric cable of the atomizer unit on the left side of the base
unit.
Water supply
Use 6 mm ID/8 mm OD pressure piping for feeding the pressurized water.
Connect piping to the pressurized-water connection on the base unit (outside
thread G3/4" or G1/2"). To prevent the inlet valve(s) from soiling, it is
mandatory to install a sieving filter valve (e.g. option Z261) in the water
supply. Install the supplied strainer valve in the pressurized-water tubing in
the vicinity of the appliance. This allows the interruption of the water supply
without shutting off the main valve.
Note: The reducing nipple (3/4" to 1/2") for direct connection of the optional
strainer valve “Z261” to the appliance is included in the delivery
schedule.
Admissible water pressure range: 1…6 bar (no pressure peaks)
Admissible water temperature: 3…35 °C
Note: Observe the local regulations regarding water connections!
