Before turning water on during either rough-in or trim-out, make sure that the cartridge retainer nuts are in place. The cartridges
and retainer nuts were properly installed and tested before leaving the factor y. Although it is unlikely, it is nevertheless possible
that through the handling of the valve by any number of persons the car tridge retainer nuts may not be properly installed. This
should be carefully checked at time of rough-in and trim-out. If the retainer nuts are not properly installed, water pressure could
force the cartridge out of the casting. Personal injury or water damage to the premises could result.
Always turn water off before disassembling the valve. Open valve handle to releive water pressure and to insure that complete water shut-off has been accomplished.
CAUTION:
SPOUT INSTALLS THROUGH 1" MINIMUM DIAMETER HOLE.
VALVE INSTALLS THROUGH 1-1/8" MINIMUM DIAMETER HOLE.
Complies with ASME A112.18.1M and CSA B125
