Page 5: How Does A Ventilation System With Heat Recovery Work
Ventilation is necessary to provide a healthy and comfortable internal environment for a building's occupants. The main task of ventilation is to remove polluted indoor air from a building and replace it with fresh outdoor air. 3. How Does A Ventilation System With Heat Recovery Work? Heat Recovery is a process of continuously heating incoming fresh air, by using the heat energy from outgoing stale, warm air and transferring a percentage of it to the incoming fresh air. -

Page 10: Operating Instructions
9. Operating Instructions Continuous ventilation is necessary to ensure a healthy indoor air quality and to maintain the building fabric in good condition at all times. Even with prolonged absence of residents (i.e. holiday) it is not recommended to switch off the ventilation unit since indoor contaminants are still being produced and entering the air, causing the air to get stuffy and a high possibility of moisture damage due to excess humidity during the heating season. -

Page 19: Fan Speed Adjustment
The installer is responsible for setting the required air volume rates for every room in compliance with the Domestic Ventilation Compliance Guide 2010. The Duplexvent BV400 unit has a 3-speed control switch which is supplied as standard. The low and high speed levels can be adjusted by manual potentiometers for commissioning purposes. - Page 20 Summer Bypass The Duplexvent BV400 unit is fitted with a bypass facility as standard. This can be used for keeping indoor air temperature at a comfortable level. If the house indoor air temperature is hotter than the unit temperature sensor setting (factory set at 22°C), with the incoming air temperature lower than the indoor air temperature, the bypass...
- Page 21 At other times the unit will recover heat as long as the related dip switch in the control box is activated. The bypass function is activated from “dip switch 3” in the control box on top of the unit. This can be switched off in the heating season to have heat recovery at all times.
- Page 22 Heating Coil Function (Optional) This function is used in units which have duct type hot water coils. It controls the hot water coil which helps to increase supply air temperature and works due to set and return air temperature. It can control 230V on/off valve connected to water coil. Note: To activate this function, following must be applied: -Turn electric heater function on.

Page 25: Maintenance Instructions
10.1 Filter Maintenance In the Duplexvent BV400, both supply and exhaust air streams are filtered through G4 class course filters. The filters should always be kept in place when the ventilation unit is in operation. To prevent the contamination of this ventilation system, to guarantee years of trouble-free operation and ensure that clean air is supplied into your home the filters must be periodically cleaned or replaced (depending on contamination of the outdoor air). -
Page 26: Heat Exchanger Maintenance
Note: The G4 filters should be replaced once every six months or after a maximum of two cleaning cycles. If an optional F7 filter is used please replace these filters after every maintenance cycle (replacement filters are available on www.airflow.com, see page 15 for part numbers). -
Page 27: Sensor Replacing Instruction
Step 3: Remove the dirt from the outside walls of the heat exchanger with a vacuum cleaner. Vacuum Cleaner Caution: Never use water or any other cleaning materials. 10.3 Sensor Replacing Instruction Return air and humidity sensor location. Outdoor air sensor location. WARNING THE FAN AND ANCILLARY CONTROL EQUIPMENT MUST BE ISOLATED FROM THE POWER SUPPLY DURING MAINTENANCE. -
