Maintenance
Occasionally, rinse debris and hard water build-up on cartridge filter screen with a toothbrush. Never take the thermostatic cartridge itself apart. Doing so will damage this precise instrument, generally make the cartridge inoperable, and void any warranty.
Frequency of maintenance varies with many factors, such as mineral content (hardness) of water supply, new construction/changes affecting any home water lines, age of property, use of well water, and so on.
Installation
The center cartridge affects only the mixed water temperature and must be βcalibratedβ to protect the end user while bathing. Calibration is simple and takes only a few additional minutes. The temperature range of mixed water is controlled through calibration setting the hot and cold limits. See Installation Guide for details.
Highly Recommended Tool: 17mm socket with long handle.
