INSTALLATION
Please follow the toilet manufacturer's installations instruction for installing the fixture. Note that the toilet
requires a minimum water supply line pressure of 20 psi for a 1.6 gpf and 25 psi for a 1 gpf fixture. Before
attaching, you should always flush the water supply lines.
After completing the installation, you are required to adjust the Cartridge Actuator (F). To adjust, make sure the
water is turned on and the vessel is completely charged. The Actuator needs to be set at the proper clearance,
1/8" from either the Flush Rod or push button. To make this adjustment, hold the Actuator while loosening the
Phillips setscrew in the center of the Actuator, and rotate the Actuator up (counterclockwise) or down (clockwise)
until the proper clearance is obtained. See Figure 1 for clearance required for flush-handle fixture. Tighten
setscrew after adjusting the Actuator.
Additional notes:
• Should your toilet continuously run-on after installing, refer to section #1 under Troubleshooting.
• You may be required to initially flush the toilet a few times to properly charge the system.
• Should your fixture develop a leak between the tank and bowl, please refer to the fixture manufacturer's
installation instructions.
