9.4. Pipework and taps
The pipe runs should be executed as short as possible. Unused pipework should be re-
moved and all remaining lagged in accordance with regulatory requirements to prevent
heat loss and condensation. All pipework connections must be made according to Fig 6. A
drain cock (not supplied) should be fitted in the position shown in Fig 6. All taps and fittings
should have a rated operating pressure of 0.6 Mpa (bar) or above.
9.5. Pressure reducing valve
The pressure reducing valve should be installed in the cold water supply to the product,
above the tundish and pointing in the direction as shown in Fig 6. The pressure reducing
valve can be connected to a maximum supply pressure of 0.9 Mpa.
