CAUTION:
Before turning water on during either rough-in or trim-out, make sure that the cartridge retainer clip is in place. The cartridge
and retainer clip were properly installed and tested before leaving the factory. Although it is unlikely, it is nevertheless possible
that through the handling of the valve by any number of persons the retainer clip may not be properly installed. This should
be carefully checked at time of rough-in and trim-out. If the retainer clip is not properly installed, water pressure could force
the cartridge out of the casting. Personal injury or water damage to the premises could result.
