The Hydroguard
®
XP MM430 and LFMM430 series is a tem-
perature actuated mixing valve designed for use in hot water
distribution systems, in compliance with ASSE 1017.
Description
n
Table 1, Capacity Tables, present the Hydroguard discharge capacity in gpm and l/m for various pressure differentials (the dif-
ference between the lowest inlet pressure and the discharge pressure at the Hydroguard).
Capacity
n
Maximum Operating Pressure ............................. 125 psi (861 kPa)
Maximum Hot Water Temperature ...................... 200°F (93°C)
Minimum Hot Water Supply Temp . ..................... 5°F (3°C) Above Set-Point*
Temp. Adjustment Ranges ** Standard: .............. 90 - 160°F (32 - 71°C)
Low: ......................... 60 - 90°F (16 - 32 C)
Hot Water Inlet Temperature Range ................... 120 -180°F (49 - 82°C)
Cold Water Inlet Temperature Range ................. 40 - 80°F (4 - 27°C)
Listing ........................................................................ ASSE 1017
Certified .................................................................... CSA B125
* With Equal Pressure
**
NOTE:
Low limit cannot be less than the cold water temperature.
For best operation, hot water should be at least 5°F (3°C) above desired set
point.

WARNING
!
TO ENSURE THE ACCURATE AND
RELIABLE OPERATION OF THIS PRODUCT,
IT IS ESSENTIAL TO:
• Properly size each valve based on the
individual application.
• Properly design the recirculation system
to minimize pressure and temperature
variations.
• Conduct an annual maintenance pro-
gram to ensure proper operation of all
critical components.
THIS VALVE MUST BE USED IN
CONJUNCTION WITH TEMPERATURE
ACTUATED POINT-OF-USE DEVICES
THAT COMPLY WITH ASSE 1016, 1069, OR
1070.
FAILURE TO COMPLY WITH PROPER
INSTALLATION INSTRUCTIONS COULD
CONTRIBUTE TO VALVE FAILURE,
RESULTING IN IN JURY OR DEATH.
