Storage request - PIR extractor fan for arch 2 WC

On snug shelf. Until required for Arch 2 WC. It’s a good unit £120, please don’t throw away.

Often wondered what exactly ‘delayed shutter opening’ means, and why you’d want it.

They use an expanding-wax actuator for the shutter, which is very very reliable (one moving part) but slow (the wax in the cylinder has to heat up)
