NOTES:

• “V” is optional depending on local codes. If a “V” type 

valve is used, it is mandatory that a thermal 

expansion tank be installed as shown. Otherwise, 

dangerously high pressure could result or water 

heater safety relief valve will frequently expel water. If 

no “V” device is used, the thermal expansion tank is 

not required.

• Install recirculation pump between last fixture and 

water heater, as shown in Figures 5 and 6.

• Use Honeywell Aquastat “T” where shown.

The AM-1 1070 Series valve provides for automatic operation 

through the use of a thermostatic element in the product. The 

element will control the mixing of the hot and cold supply water 

to provide mixed, tempered, water to connected fixtures. This 

provides constant water temperature under different working 

conditions.

Thermostrip temperature indicator easily indicates water 

temperature 110° - 140° F (43° - 60° C) for accurate control 

and quick set-ups.

Clean pipe to mix outlet of valve and firmly apply Thermostrip. 

Flow water and adjust mixed outlet temperature for desired 

setting range. Actual mixed water temperature is indicated in 

green with 2° F and 1° C increments. Blue means slightly lower 

and brown means slightly higher.

Thermal temperature indicator strip is One Time use only for 

initial system temperature setting. Check date code printed on 

temperature strip to ensure temperature reading accuracy.

Annually, the valve should be tested to determine that the 

internal parts are free to properly operate. Turn on the hot 

faucet and let run for a few minutes, until the hot inlet 

temperature is at its maximum. Loosen the screw on the cap 

with a Phillips screwdriver. Lift the cap until the bottom 

disengages from the brass hex. Adjust the hand wheel up or 

down one-half turn. Check the outlet temperature with a 

thermometer under the faucet and make sure that the 

temperature changed and the hand wheel turned without 

binding. Reset the correct outlet temperature, push the hand 

wheel down to lock the setting, and tighten the retaining screw.
