Care should be taken when replacing the cartridge. The water supply must be switched off and any residual pres­sure relieved before starting work. Once the new cartridge is fitted the date ring should be reset and the instal­la­tion checked for leaks. Max working temper­a­ture 30 c. Please note: These units will be affected by hot water transfer back down the system, there­fore they must be installed as far away from the boiler as possible (minimum 1m).
