LP-314 REV. 3.24.14
This appliance can deliver scalding temperature water at any faucet in the system. Be careful whenever using hot water to avoid
scalding injury. By setting the thermostat on this appliance to obtain increased water temperature, you may create a higher potential for
scald injury. To protect against injury, you should install an ASSE approved thermostatic mixing valve (a device to limit the temperature
of water to protect against scald injury by mixing hot and cold water supply) in the system. This valve will reduce point of discharge
temperature in branch supply lines. This appliance was shipped with an ASSE approved thermostatic mixing valve. Install this valve
according to the directions in the mixing device container. DO NOT OPERATE THIS APPLIANCE WITHOUT AN ASSE APPROVED
THERMOSTATIC MIXING DEVICE. If this appliance was shipped without an ASSE approved thermostatic mixing valve, contact the
manufacturer.
The mixing valve is certified to ASSE 1017. It is not to be used to provide anti-scald service resulting from system pressure fluctuations,
and should not be used where more sophisticated compensating temperature controls are required.

Notes:
1
Maximum permissible temperature in accordance with ASSE 1070. The limit locking ring may be adjusted for applications not requiring
ASSE 1070 valves.
2
Maximum allowable variation in either supply pressure in order to control the outlet temperature to within +/- 3
o
F. Warning: Pressure
variations outside of this range may cause changes in the outlet temperature.
NOTE: At low flow operation, the outlet temperature may vary slightly more.
Differential pressure at the valve inlet should be within a 2 to 1 ratio under normal flow conditions.
Inline fittings, pipe work, layout and sizing must be taken into consideration. In installations where the valve is supplied with unbalanced
hot cold pressures greater than a 2 to 1 ratio, please call HTP Technical Support Department.
Installation of the Mixing Valve
1. Flush all pipe work thoroughly (with water only) before installing the mixing valve.
2. The mixing valve comes complete with union type connections for ease of installation and service.
3. The mixing valve must be removed from the pipe work prior to soldering the end connections. It is recommended to use a spacer
piece while soldering.
Do not solder unions while attached to the valve body. Solder connections prior to connecting unions to the valve body to avoid
damaging the valve and its function.
