With the system still hot, turn off the gas, water andelectricity supplies to the boiler and drain down tocomplete the flushing process.Note. A flushing solution should be used during the flushingprocedure. Flushing solutions, Fernox Superfloc,Sentinel X300 (new systems) or X400 (existingsystems). Refer to Frame 6.4. Refill and vent the system, add inhibitor (see Frame 6),clear all air locks and again check for water soundness.Affix the water treatment warning label, supplied in thehardware pack, in a prominent position on the system, toprevent the use of incorrect water treatment additives.5. Reset the system initial pressure to the designrequirement.6. Balance the system. Refer to Frame 5.7. Finally, set the controls to the User's requirements.Note.
