Step 2 - Prepare Manifold Connections
•
It is essential that no fittings, other than those specified in the instructions, are
installed within the ‘expansion zone’. This is everything beyond the check valve,
located within the manifold. See Diagram 3.
•
Use Diagram 1 to establish suitable locations for each component which forms part
of the full installation.
•
Note the boiling tank must be located as close to the tap as practicable as it is not
possible to extend hoses provided.
•
Attach ½” M BSP to 15 mm compression fitting to offtake 1 of the manifold and
tighten with spanner, see Diagram 3. Connect desired length of copper pipe then
connect to pressure relief valve.
•
Pressure relief valve is a safety device which must be fitted and piped to drain via air
gap before commissioning.
•
From offtake 3 of the manifold attach hose labelled ‘manifold to exp vessel’ using 1
black washer.
