Procedure for Operating the Potable (Drinking) Water System

The procedure for initiating the drinking water hydrophore is the same as for the fresh water hydrophore except that the suction is taken from the drinking water tank by one of the drinking water pump and FW mineraliser being in use.

Inlet and outlet valves on the mineraliser unit, FG12V and FG14V and line valve FG16V should be opened. The hydrophore outlet valve FG52V should be opened slowly and drinking water supplied to the domestic drinking water services via the FW mineraliser and line outlet valve FG16V which bypasses the line into the steriliser unit which has now been relocated onto the FWG outlet.
