IMPORTANT
Please read all of the instructions before installation
Avoid restrictive piping, fittings or sharp angled bends when plumbing the mixer.
Do not hydrostatic test the installation with this mixer installed. Damage to the ceramic
headworks may occur.
All pipe-work must be thoroughly flushed prior to installation of the mixer. In-line filters must
be installed on both hot and cold supplies to prevent foreign particles damaging the ceramic
headworks.
NOTE: It is the responsibility of the installer to ensure a water proof seal is achieved
between the faceplate and finished surface of the wall. If in any doubt about the quality
of the seal the faceplate should be removed and then reinstalled using silicon to ensure a
seal is achieved.
