How to Drain Hot Water Storage Cylinder
Isolate mains water supply at stop valve on Inlet Control Group and close
-turn valve (handle at 90° to valve body) on
double check valve - see Fig. 14.
Fit a hosepipe to the tail of the drain valve (secure with “Jubilee” clip), and run open end to a low level where water
can be safely drained.
Open nearest tap(s) fully (to allow air to enter cylinder) before opening the drain valve above hose.
Note:
The lower
the open end of the hose, the faster will be the draining effect.
When refilling: check that the secondary expansion vessel pre-charge pressure is between 2.5 to 2.7 bar and allow
water to flow freely before closing tap(s).
