8) Flush the Pipework
Flush out the pipework in accordance with Water Bylaws 2000 (Scotland) and BS 6700:1997 (England
& Wales). The use of a Horne flushing kit is strongly recommended, because this connects directly to
the water inlets on the mixing valve. Access to the flushing points is gained from underneath the
casing through the lower end cap. Using the supplied 4mm hex key, isolate the cold and hot water
supplies at the low level servicing valves. Remove the strainer cap and strainer basket and screw in
the flushing adapter. Place the end of the flushing hose in an appropriate drain or container and turn
on the supply to flush as required. Remove the flushing adapter and replace the strainer cap. Repeat
for both hot and cold supplies. See Figs 6 & 7.
NOTE THAT IF THERE IS ANY DANGER OF FREEZING THEN THE PIPES AND TSV1-3 MUST BE
DRAINED TO AVOID DAMAGE.
