2.1 Installing The Flush Valve Assembly
•
Identify that all components are in the packaging. Three components are included
in the packaging:
i)
An isolating ball valve and strainer combination c/w fi tted Nautilus Solenoid;
ii)
Connecting nut and vacuum breaker assembly;
iii)
PVC loose nut cap and lining.
•
Flush the water supply lines thoroughly to remove any dirt or debris that could
foul the fl ush valve.
•
Fit the fl ush valve in the required position maintaining a minimum 700mm
distance between the outlet of the vacuum breaker and the centre line of the
lush pipe connected to the WC pan inlet.
Note:
Contact RBA for performance
assessment
•
It is recommended that a loose nut or union connection be used at the inlet ball
valve to facilitate ease of assembly removal should this be required.
•
Once installation heights have been established, fi t the Connecting Nut and
vacuum breaker assembly to the ball valve and Nautilus Solenoid.
•
Fit the PVC cap and lining to the fl ush pipe, tightening the loose nut onto the
male outlet thread of the vacuum breaker.
• Connect
fl ush pipe to the WC fi xture.
•
Turn water supply on and check for leaks. Note: A small amount of water may
pass through the Nautilus Solenoid valve when power is not connected to it. The
correct function of the Nautilus solenoid should see pressure equalise across the
diaphragm causing the valve to remain closed.
•
Connection of the Nautilus Solenoid to the piezo’s for half and full fl ush along
with Electronic Controller and Power Pack is required to complete the installation
•
Once commissioning has been completed, test the system by pressing the half
fl ush piezo checking that the valve closes off after the fl ush has been actuated.
•
Test the system by pressing the full fl ush piezo checking that the valve closes off
after the fl ush has been actuated.
•
Visually inspect the WC pan during full fl ush for correct operation
