TEMPERATURE ADJUSTMENT CONTINUED...
1. The Mixed Water Supply Temperature may require adjustment. The IMD is set at approximately
120°F when the arrow on the hand wheel and the arrow on the casting are aligned.
a. To Increase Mixed Water Supply Temperature: Depress and rotate the hand wheel
counter clockwise until the desired set point is reached (see Figure 9). Refer to thermostrip
temperature reading for desired set point (hot water must be flowing at a minimum of 1 gpm
to accurately read thermostrip). Ensure the hand wheel snaps back to the locked position
once desired set point is reached.
b. To Decrease Mixed Water Supply Temperature: Depress and rotate the hand wheel
clockwise until the desired set point is reached (see Figure 9). Refer to thermostrip
temperature reading for desired set point (hot water must be flowing at a minimum of 1 gpm
to accurately read thermostrip). Ensure the hand wheel snaps back to the locked position
once desired set point is reached.
2. Verify that the desired set point is reached by allowing an appropriate
amount of water to run from the nearest faucet supplied by the IMD.
CHECKING / SERVICING THIS DEVICE
It is recommended that the IMD is checked annually to ensure proper system capabilities.
Where adverse water conditions are applied, more frequent intervals are recommended.
In checking the mixed water supply temperature, use the same faucet used in the initial
installation temperature adjustment.
There may be some variation in the water temperature from the IMD due to seasonal
temperature variations in the cold water supply.
If the water supply is of poor quality, the internal components may jam requiring an
additional filter or strainer to be fitted to the system. Contact a plumbing professional for
appropriate materials and installation.
