3 .0 Use Infomation The HR04 (Fig. ) and HR05 (Fig. ) ae whole house ventilation units. This appliance must e installed in accodance with the manufactues instuctions and the egulations in foce. HR04 Duct systems must e installed in accodance with CIBSE guides and BRE Digest 398. HR05 Fig. Read the instuctions fully efoe installing o using the appliance. Waning : The ventilation fo any open flued appliance must always e consideed efoe siting the extact and inlet vents, the vents must also e sited away fom othe flue teminals, ventilatos etc. on the outside of the dwelling. In addition thee shall e adequate ventilation of the oom when the cooke hood is used at the same time as appliances uning gas o othe fuel. The exhaust ai duct must not e dischaged into a flue which is used fo exhausting fumes fom appliances uning gas o othe fuels.

4 .0 Use Infomation HR04 Impotant: The HR04 is not suitale fo installation aove any cooking appliance. HR04 The HR04 is a mechanical ventilation with heat ecovey (MVHR) unit. The unit povides continuous extaction of stale ai fom the dwelling typically fom the athoom and fom the kitchen. The stale ai passes though the heat exchange efoe eing ducted to outside. Fesh ai fom the outside is continuously dawn into the unit and passed though a filte and then into the heat exchange. In the heat exchange the fesh ai is pewamed and ducted into the dwelling typically to living ooms/ edooms. HR05 HR05 The HR05 is a mechanical ventilation with heat ecovey (MVHR) unit, designed solely to opeate with the Vent-Axia telescopic cooke hood. The unit povides continuous extaction of stale ai fom the dwelling typically fom the athoom and the kitchen. The stale ai passes though the heat exchange efoe eing ducted to outside. WHC0005A Fesh ai fom the outside is continuously dawn into the unit, passed though a filte and then into the heat exchange. In the heat exchange the fesh ai is pewamed and ducted into the dwelling typically to living ooms/ edooms. When the telescopic hood is extended the MVHR unit switches automatically to oost. The hood daws steam and fumes fom cooking though metal filtes and diect to outside. Impotant: The cooke hood must always e fully opened when the cooke /ho is in use. Waning: Do not flamé unde the cooke hood 4
