INSTALLATION INSTRUCTIONS
THESE INSTRUCTIONS MUST BE
LEFT WITH HOMEOWNER
Always turn water OFF before disassembling the faucet. Open faucet handles to relieve water
pressure and to insure that COMPLETE water shut-off has been accomplished.
Before turning water on during either rough-in or trim-out, make sure the cartridge retainer nuts are in place. The cartridges and
cartridge retainer nuts were properly installed and tested before leaving the factory. Although it is unlikely, it is nevertheless pos-
sible that through the handling of the faucet by any number of persons the cartridge retainer nuts may not be properly installed.
This should be carefully checked at time of rough-in and trim-out. If the cartridge retainer nuts are not properly installed, water
pressure could force the cartridge out of the faucet body. Personal injury or water damage to the premises could result.
