⑤ Cartridge clogged

      • Remedy: Remove and clean the cartridge

① Heater temperature set too low

      • Remedy: Turn up the heater temperature

② Temperature limited stop restriction

      • Remedy: Adjust the temperature limit stop

Warning

Setting the Adjustable Temperature Limit Stop in The Last Position or beyond The Last Position (counterclockwise) could result in scald injury. It is vital to adjust the Adjustable Temperature Limit Stop to avoid scald injury to the user when the handle of the valve is rotated to the hot side. Please check your local plumbing codes for maximum water mix temperature (normally should not exceed 120℉). If inlet water temperature changes seasonally, you may need to readjust the Adjustable Temperature Limit Stop. Recommended water temperature for bath or shower is between 90-110℉。 Run the water so that the cold water is as cold as it will get and hot water is as hot as it will get. Place the handle on the cartridge stem and rotate the handle clockwise until the handle stops. Place a thermometer in a plastic tumbler and hold in the water stream. If the water temperature is above 120℉ or the maximum temperature requirement of local plumbing codes (whichever is lower), the Rotational Limit Stop must be readjusted clockwise to decrease outlet water temperature.

MAKE SURE COLD WATER FLOWS FROM THE VALVE FIRST. MAKE SURE WATER FLOWING FROM THE VALVE AT THE HOTTEST FLOW POSSIBLE DOES NOT EXCEED 120℉ OR THE MAXIMUM ALLOWED BY YOUR LOCAL PLUMBING CODES.
