Important! Since the coupling works with tapping
rings, it may leak if you undo and reconnect the lines.
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. If any bubbles form, the system
has a leak and the screw connectors must be
retightened using an open-ended spanner.
5. 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 now open.
If 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.
Important! The conical ring on the valve has an
important sealing function together with the sealing
seat in the caps. Ensure that you do not damage the
cone and that you keep the cap free of dirt and dust.
6. Now remove the cover on the bottom 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 now open.

7. After completing steps 1 – 6, check that all the
connections are sealed correctly using leak
detection spray or soap suds. If any bubbles
form, the system has a leak and the screw
connectors must be retightened using an open-
ended spanner.
8. Start the equipment so that the operating
pressures build up inside it. Check all the
connectors again for signs of leaks
a) during cooling mode
b) in heating mode.
If any bubbles form, the system has a leak and
the screw connectors must be retightened using
an open-ended spanner.
