WIRING & PULLING
Current IEE Regulations: AT-WM should be installed by a competent installer, in accordance with the recommendations
laid down by the HVCA and sound engineering practice.
D. PLUMBING INSTALLATION
The diagrams will serve as a visual aid, but it is recommended that a competent plumber carries out the assembly and
installation. Connect the pipe to the water meter / valve according to markings on the valve body. Apply pipe compound
sparingly to male threads only. Ensure compound does not enter valve. Avoid pipe strain by proper support and align-
ment. Type PN16 mating flanges will be required on some models over 50mm.
E. HELPFUL HINTS
We recommend that AT-WM is installed with a maintenance by-pass. The water meter can be fitted vertically or horizon-
tally. Note the direction of the flow arrows marked on the water meter and valve to ensure they are fitted correctly.
F. MAINTENANCE
Clean periodically depending on conditions. Keep the medium flowing through the water meter / valve as free from dirt
as possible. While in service, the Solenoid Valve should be operated at least once a month to ensure proper cleaning and
closing. We strongly recommend a strainer is fitted prior to any meters or valves to prevent debris fouling the mecha-
nism.
