The Return Air grille is where your system draws the air back into the fan coil to re-condition the air, and pass it out your outlets. Your air con will naturally create a circular airflow out of your outlets, back towards the return air grille and circulate it back around the house through the ductwork.
The Return Air filter needs to be cleaned regularly. To do so, you must find the small pins at one of the long ends, and pull them away from the framework. The face will then hinge on the opposite end, allowing you to access the filter and slide it in and out of its housing behind the grille.
Every 3-6 months you must check this filter, and if required, bang or hose out the filter gently to clean it of the built up dust.
If your Purtech Return Air grille comes with the optional Alarm, you must still check the filter on occasion- the alarm acts as a failsafe only.

Generally, we request that you keep your doors open at all times whilst you are operating your air conditioning. This is to assist in the circulation of the air, reduce the resistance in the air pressure that is created by putting too much conditioned air into a sealed room and efficiency of the system. As a minimum, we require at least a finger width gap under the door when closed.
If this can't be done, please request an additional return air grill in the sealed room or order an SSRV- a pressure relief vent to release air into your ceiling cavity.
