AMX Series DirectConnect™
APPLICATION
Any application requiring accurate control of water
temperature based on mixing of hot and cold water, such as:
• Domestic water for residents designed to be mounted
directly on the water heater.
• Hotels, schools, hospitals, or nursing homes.
• Space heating.
• Radiant floor heating.
• Central distribution systems.
• Combo systems.
• Heat pump systems.
• Industrial applications.
Benefits
AMX Series DirectConnect
™
Mixing Valve provides energy
savings, increased comfort and safety for the user.
Operation
Automatic operation is provided by thermostatic element.
Element will control hot and cold supply based on valve
setting. If cold water is shut off, valve reduces mixed flow rate
in seconds.
CAUTION
Injury Hazard.
Exceeding mix temperature can cause burns.
For domestic water applications the AMX Series
DirectConnect Mixing Valve temperature should not
exceed 120° F (49° C).
Service
To remove dirt, flush valve. To remove calcium deposits, soak
valve in vinegar for 24 hours and flush, or contact
factory.Temperature Selection
The AMX Series is made with a temperature range of 90° F to
130° F (32° to 54° C). The factory mix output setting is at
120° F (49° C), using the following normal conditions: 140° F
(60° C) hot water input and 60° F (16° C) cold water input.
Conditions different than the normal setting may require
readjustment to achieve the 120° F (49° C) mix output
temperature.
To change the output mix temperature requires a 3/16 in.
Allen
®
wrench, which is included.
1. Punch through the center of the temperature range
label.
2. . Adjust temperature mix output by turning the screw
clockwise to decrease the mix temperature and
counterclockwise to increase the mix output
temperature.
3. Use a thermometer to verify mix output temperature.
IMPORTANT
Do not operate the valve at temperatures outside of
its calibrated range.

and 4)
Use when water temperature produced by heater is hotter
than desired at point of use. Many codes require that water
supplied to the system be limited to 120° F (49° C) maximum.
