4.0 COMMISSIONING 4.1 PLUMBING WARNING: Water that is left standing in a stainless steel water cylinder for long periods without draw-off will become de-oxygenated and potentially corrode the vessel material. If the installation is to be left unused following installation and com- missioning, the water cylinder must be drained or regularly flushed (once a week) through with fresh mains water. -
Page 15: Explanation To Customer
IF WATER DISCHARGES FROM ANY SAFETY VALVE FITTED SWITCH OFF THE ELECTRICAL SUPPLY TO THE UNIT IMMEDIATELY. CONTACT THE SANTON SERVICE TEAM (TEL: 0844 8711530) OR AN APPROVED INSTALLER. DO NOT TURN THE ELECTRICAL SUPPLY ON AGAIN UNTIL THE UNIT HAS BEEN CHECKED AND APPROVED BY A QUALIFIED INSTALLER. - Page 16 6.1 DESCALING Little maintenance is required, however in hard water areas the unit will require periodic descaling to ensure efficient operation. To descale the unit: Switch off and disconnect the electrical supply. Turn off the water supply to the unit. Open a hot tap to relieve any system pressure.
- Page 17 6.3 EXPANSION VESSEL PRECHARGE PRESSURE The Expansion Vessel should have a precharge pressure of 3.5 bar (51p.s.i.). This can reduce over time and eventually require re-charging. To do this: Turn off water supply to the unit; open a hot tap to relieve system pressure. Remove dust cap from top of Expansion Vessel.
