QI am looking to mount this to the outlet face of an air con unit (rectangle) and fit flexible ducting to the round face to deflect the flow of air. What is the best way to mount the rectangle face to the flat face of the air con unit? This unit is a Friedrich Chill+ Series EP12G33Banswer nowA Hello James I have looked at the installation instructions for the Chill series and there does not appear to be any reference to diverting airflow with ducting or, for that matter, a detailed diagram or dimensions of the exhaust? Are you sure it is suitable for this application?Any adaptation or modification to the equipment will most likely ify the guarantee. The product referenced is a converter for rectangular duct to round and does not have any part that would fix it to the flat face of your machine?
Hi. Id like to glue this product to the pvc pipe DUCVKC660. Will using pvc solvent cement be ok? as the fitting is Polypropylene and it seems that these two materials cant be bonded to each other.
Many thanks

This item was used to cover piping in a wc. Worked okbut obviously not what the unit was intended for.
Ray Whalley (verified owner) –
This critical component made the transition from 150mm diameter to the equivalent in rectangular form via a short length of flexible round aluminium duct to the fan outlet. Seal to straight ducting with 50mm wide Duck Tape USA white.
