Now tighten the bottom screw connector first and then the top screw connector using the
open-ended spanner. Hold the points marked "1'' using an open-ended spanner and turn the nuts
only at the points marked "2" using an open-ended spanner (Select the appropriate
spanner according to the dimensions of the connector), see Fig.6.4
•
Ensure that the screw connectors do not skew as you tighten them and work quickly. See the next
page for the proper torque.
IMPORTANT: Since the coupling works with tapping rings, it may leak if you undo and reconnect
the pipes. This will also void the warranty.

After completing steps 1- 4, check that all the connections are sealed correctly using leak detection spray
or soap suds. lf any bubbles form, the system has a leak and the screw connectors must be retightened
using an open-ended spanner.

Now remove the cover on the top valve using a 19 mm open-ended spanner. Open the valve by
turning it counter-clockwise as far as it will go using a 5 mm Allen key. The valve is naw open. lf
the valve is not opened fully, the system may malfunction and suffer damage. Screw the cover back
on to the top valve and tighten it well to ensure that it is properly sealed. See Fig.6.5.
