Page 8: Pre-Installation Checklist
Pre - Installation Checklist • Does the unit fit through the loft hatch? • Check there are no obstructions in the hallway or landing where the diffuser is to be fitted and in the loft space above. • Ensure the loft has adequate cross-flow ventilation to provide a supply of fresh air to the unit. - Page 9 In conditions between 19°C - 25°C the units will increase air flow rate by 10%. Above 25°C the PIV & MIV airsource units automatically switch to bringing air directly from outside to avoid bringing hot air into the property from the loft space. The PIV unit uses a single 200mm diffuser to provide air into a hallway or landing area.
