IMPORTANT

 Carbon filters / pellets are not to be ingested  

and hands are to be thoroughly washed after handling.

9.3 Replacing Particulate Filter

To ensure effective particulate filtration and low system resistance, 
optional air filters must be replaced every 12 months. Replacement 
filters are available for purchase direct from Nuaire, with the relevant 
part codes shown in this document.

There are two particulate filters per unit, these are located within Pod A 
and Pod B. 

Ensure unit is isolated from mains power supply. 

Unscrew the fixings securing the lid(s) in place and remove from 
unit.

Lift out and remove the filter(s).

Fit the replacement filter ensuring the airflow direction matches 
the air flow of the unit.

Refit lid(s) and restore power to the unit.

IMPORTANT

In the event of RF interference between 84MHz to 89MHz 

the fan speed may increase to full speed. Operation will return 

to normal when the interference stops.

8.0 HEATER CONTROL (Heater Versions Only)

When the orange LED on the diffuser control panel is illuminated, the heater is 
active in autoheat mode and is controlled by the temperature setpoint. When 
the orange LED is not lit, the heater is off.

In order to enable the heater, press the DOWN button for five seconds and 
release. The orange LED will illuminate indicating that the heater is active and in 
auto heat mode.

To turn the heater off, press the DOWN button for five seconds and release. The 
Orange LED will no longer be illuminated, indicating that the heater is off.

8.1 Setting the Temperature Set Point

A temperature sensor is fitted to the outlet of the heater and will control the 
heater output to maintain the set point. The set point ranges between 5˚C (fully 
anti-clockwise) and 15˚C (fully clockwise) and can be adjusted via the min/max 
commissioning pot located on the ceiling vent diffuser.

9.0 MAINTENANCE

IMPORTANT

Isolation - Before commencing work make sure that the unit and Nuaire 

control are electrically isolated from the mains supply and switched live 

supply.

Appropriate PPE (Personal Protective Equipment) should be worn 
during maintenance. Precautions may also be needed to protect the 
surrounding area from excess carbon residue.

To ensure the carbon filter maintains its high reduction of NO2 the 
filter must be replaced once the end of its lifespan has been reached. 

The lifespan of the carbon filter in normal circumstances is shown in 
the table below.
