The Nuaire Drimaster DRI ECO HC provides whole-home ventilation using the Positive Input Ventilation (PIV) principle. It introduces fresh, filtered air into the dwelling at a continuous rate, promoting air movement from inside to outside. The unit is mounted in the loft space, drawing air through filters and inputting it at ceiling level into the property.
The unit includes an internal sensor to regulate the fan speed according to the loft temperature. The sensor increases airflow to the dwelling when the loft is warmer than the house. The Fixed Temperature Heat Recovery strategy, achieved via the internal sensor, improves energy performance.
All controls for the fan are in the ceiling vent, allowing the user to control, program, and monitor the unit from inside the property. The airflow can be set to suit the house size and its response to temperature changes.
Ensure the loft has adequate ventilation. Cover and seal all water tanks and lag water pipes. Ensure any extract fans discharge outside, not into the loft. Seal the loft hatch tightly and ensure all ceiling holes, such as light fittings, are sealed. Conduct a visual inspection of flues or chimneys for leakage. If leakage points are found or if there is any doubt, advise the house owner/provider before proceeding with the installation.
Place the diffuser in the central hallway of single-storey properties or the ceiling of the top floor landing in multi-storey dwellings. The diffuser discharges air evenly in all directions along the underside of the ceiling.
Speed Setting 1: 100mm
Speed Setting 2: 155mm
Speed Setting 3: 400mm
Speed Setting 4: 625mm
Speed Setting 5: 850mm
Speed Setting 6: 1000mm
Smoke Alarms: Ensure the diffuser is not placed within 1 metre of a smoke alarm. If repositioning is not possible, close off two sides of the diffuser using the air dams supplied to guide airflow away from the smoke alarm.
Fit air dams where needed to alter the direction of airflow. Two air dams are supplied and fit on any of the diffuser sides to guide airflow away from smoke detectors or obstructions.
Use the tear-out template from the unit packaging lid and trace the shape onto the ceiling between two convenient joists.
Cut out the shape and position the ceiling vent.
Secure the vent using the 4 screws and plugs provided.
Connect the fan unit to the diffuser using the loom provided.
Attach the diffuser cap to the frame using the four built-in press-on clips provided.
Attach the filter to the main body of the unit by pressing the filter's rim by hand until it clips into place. Attach the unit to the roof via the cord provided or fix it to the floor joists using the optional anti-vibration mounting kit.
Suspend the unit from a convenient roof beam via the cord supplied. Insert the flexible duct (maximum length 2M) over the fan outlet and secure it with a cable tie. Repeat the process for connecting the duct to the ceiling vent. Ensure all duct joints are airtight and avoid installing the flexible duct in a compressive state.
Purchase the AV kit direct from Nuaire (code number: 771393) if required. Attach battens (not supplied) to the joists, mark, and drill 12mm diameter clearance holes in the ends of the battens. Place anti-vibration mounts above and below each batten fixing point. Use the 4 large screws and special washers to fix the unit to the joists. Do not overtighten the fixings.
Note: Electrical connection must be carried out by a qualified electrician.
Voltage: 230V 1ph 50Hz

The three-core mains cable from the unit should be connected to a fixed wiring installation via the supplied fused spur, in accordance with current IEE wiring regulations. Incorporate disconnection from mains within the fixed wiring with a maximum contact separation of 3mm.
EMC Engineering Practice: Ensure the power supply output cable and any sensor cables are not placed within 50mm of other cables or each other.
For units installed in 3-storey properties, install alarms with separate relay bases to ensure the unit switches off in the event of smoke/CO detection. Recommended suppliers include Kidde (www.kiddesafetyeurope.co.uk) and Aico Ltd (www.aico.co.uk).
The unit has 6 airflow rate settings, controlled via switches on the underside of the diffuser.
