† Devices tested to ASSE 1069 or ASSE 1070
such as Watts Series LFUSG or LFMMV should
be used at fixture to prevent possible injury.
1. Let water flow for at least two minutes to allow
supply temperature to stabilize.
2. Calibrate the mixed water outlet temperature
by placing a thermometer in the mixed water
stream.
3. To adjust the setting of the valve, loosen locking
cap screw with hex wrench, see Figure 3. Cap
must be lifted 1/4" to adjust temperature. To
increase the temperature, turn counterclockwise.
To decrease temperature turn clockwise.
4. Lower handle and tighten screw.
5. Check outlet temperature.

Installation
Valve should be installed and adjusted by a licensed contractor in accordance with local
codes and ordinances. Further, this valve should be installed in a location where it is acces-
sible for cleaning, service or adjustment.
1. Close both the hot and cold water shutoff valves upstream nearest to the intended installation.
2. Bleed the remaining water from the system.
3. Connect the water supply to valve as shown in Figure 1, 2 or 3 depending on application.
Supply piping must be flushed clean before making connections to the valve.
4. Valve can be installed in any position. The inlet hot supply is to be connected to the “H” side
of the valve, the cold supply side to the “C” side and the mixed water outlet to the “M” side.
5. Make sure union nuts are placed over tailpieces prior to soldering threading to pipe or using w/press.
6. For valves with Quick-Connect tailpieces refer to "Quick-Connect Installation" instructions below
To prevent damage to valve from excessive heat during soldering, remove unions and gaskets
from valve body prior to soldering.
7. After soldering, flush piping and install valve using filter washer on hot and cold water inlet and
fiber washer on the mixed water outlet.
8. Start-up: Open cold water supply, then hot water supply. Inspect for leaks.
9.
Adjust temperature to desired setting (see Temperature Adjustment Section). Watts recom-
mends a maximum temperature of 105°F (41°C) for shower and bathing fixtures.

FAILURE TO COMPLY WITH PROPER INSTALLATION AND MAINTENANCE
INSTRUCTIONS COULD CONTRIBUTE TO THE VALVE FAILURE, RESULTING IN
INJURY AND/OR DEATH.
TO ENSURE THE ACCURATE AND RELIABLE OPERATION OF THIS PRODUCT,
IT IS ESSENTIAL TO:
• Properly design the system to minimize pressure and temperature variations.
• This valve is not factory preset and can be adjusted to deliver scalding tempera-
tures. Check outlet temperature to ensure it does not exceed 105°F (41°C).
Make sure temperature limit stop is properly re-set to maximum 105°F (41°C) fol-
lowing valve maintenance or repair. Tampering with limit stop in any way may result
in scalding temperature causing serious bodily harm and/or death.
WARNING
!
WARNING
!
Need for Periodic Inspection and Yearly Maintenance:
Periodic inspection and yearly maintenance by a licensed contractor is required.
Corrosive water conditions and/or unauthorized adjustments or repair could ren-
der the valve ineffective for service intended. Regular checking and cleaning of
the valve’s internal components and check stops helps assure maximum life and
proper product function. Frequency of cleaning and inspection depends upon
local water conditions.
You are required to consult the local building and plumbing codes prior to installation.
If the information in this manual is not consistent with local building or plumbing codes,
the local codes should be followed. Inquire with governing authorities for additional
local requirements.

NOTICE
To prolong the life of the series LFMMV
when used in an ASSE 1017 application,
it is recommended that it be trapped
as shown; i.e. the hot water inlet to the
LFMMV should be 8"-12" (200-305mm)
below the hot water supply feed.
Problem & Cause
A. Unable to reach required set point or set point difficult to set
A.1 Supply temperatures not within specified limits
A.2 Hot and cold supplies reversed
A.3 Filters are blocked by debris
B. Unable to achieve required flow
B.1 Too much pressure drop at fixture
B.2 Checks valve/filters blocked by debris
C. Valve does not maintain required temperature or tempera-
ture changes over time
C.1 Fluctuation in supply pressures
C.2 Check valve/filters blocked by debris
C.3 Recirculation loop not piped properly
