resideo Braukmann 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.
FEATURES
- Designed to be installed directly on the water heater hot port.
- Dual purpose mixing or diverting valve.
- Constant water temperature under different operating conditions.
- Proportional valve (control of hot and cold water).
- Flow reduction in seconds if cold water supply is interrupted.
- Temperature adjustable using 3/16 in. Allen® wrench (included).
- Union coupled tailpiece connections included.
- Heat trapping not required.
- Recirculation connection for fast response.
- Integral check valve on cold water port.
- Bronze/stainless construction.
- Teflon® coated wear surfaces to prevent lime deposits.
- Maximum pressure differential between hot and cold ports is 7 psi (48 kPa).
- ASSE 1017 certified. CSA and IAPMO listed.
- Lead-Free.
- Patent Pending.
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.

Lead-free Plumbing Code Compliance: The wettable surface of lead-free models contain less than 0.25% of lead by weighted average
Temperature Selection
The AMX Series DirectConnect is made with a temperature range of 90 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 it requires a 3/16 in. Allen wrench, which is
included.
- Punch through the center of the temperature range label.
- Adjust temperature mix output by turning the screw clockwise to decrease the mix temperature and counterclockwise to increase the mix output temperature.
- Use a thermometer to verify mix output temperature.
IMPORTANT
Do not operate the valve at temperatures outside of its calibrated range.
TYPICAL INSTALLATION DIAGRAMS
Domestic Water Mixing
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
Recirculation Loop
The purpose of a recirculation loop is to supply immediate tempered water to
all hot water fixtures. This helps conserve water usage. In the recirculating
loop, the hot water supply returns from the furthest fixture from the heating
source andis connected to the AMX mixing valve recirculation port and the cold
supply line of the water heater, storage tank or boiler. The AMX Series
DirectConnect mixing valve allows easy recirculation connection through the
integral recirculation port. A temperature controlcirculating pump is required
to move the tempered water in the recirculation loop. The Resideo L6006C1018
Aquastat® Control is the recommended temperature control device for the
circulator. The Resideo Aquastat Controller should be set 5 to 10 °F (-15 to
-12 °C) below the set mixed outlet temperature.
CAUTION
Injury Hazard. Can cause severe burns. If the circulator pump is continuously
running and not temperature controlled by an Aquastat Controller, the
recirculating loop temperature could exceed the set mixed temperature and
reach scalding temperatures during no demand periods
Legend:
- Check Valve.
- Alternate pump location.
- V = Any device which turns the domestic water system into aclosed system, such as backflow preventers, check valves or pressure reducing valves.
- T = Recirculation pump thermostat control
NOTE : 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, dangerous high pressures could result or water heater safety relief valve will frequently expel water. If no V device is used, no thermal expansion tank is required
Space Heating
Boilers must operate at a water temperature higher than the desired
temperature in the heating system in order to perform at maximum efficiency.
Example: radiant floor heating.
