Subject to alterations Page 10 of 33Water connectionThe inner tank surface is enamelled and the tank is equipped with a sacrificial anode.All connectors have 3/4” threads, with the exception of the anode access which is a 5/4” sleeve.All water pipes are connected to the bottom of the unit.If required, hot water circulation can be established by fitting a non-return valve to the recirculationconnector of the tank after inserting a 80cm long circulation pipe (optional accessory) into the tank.See figure 3 below.If hot water circulation is not required, the connector and fitted blanking plug should be left un-touched.Hot water circulation may result in considerable heat loss within the piping system. A large propor-tion of heat pump output may therefore be lost. To prevent heat loss, circulation and hot waterpipes must be insulated with at least 30mm of mineral wool or other type of pipe insulating materi-al.12: Cold water13: Hot water14: Return supplementary coil15: Inlet supplementary coilFigur 6: Water connectionsNote: The water tank must be filled with water before the unit start up.Supplementary heating element DHWThe hot water tank has a supplementary heating element of 1,5kW.
