OVERBUILT IS AN UNDERSTATEMENT
Failure to comply with all aspects of these instructions may result in unsafe performance.
All installations must comply with relevant State, Provincial and Local Authority requirements.
Check valves:
Check valves are integrated in the cold and hot water inlets of the valve. For correct and safe system function, ensure
that the check valve is clean of debris and functioning correctly.
Flush the system thoroughly before fitting Heatguard:
It is critical that all debris is flushed from the pipework prior to installing the valve. Not flushing the system properly is
the most common cause of system difficulties.
Delivery Temperature:
The temperature of the hot water supplying the mixing valve should be at least 27°F higher than the maximum
required valve setting. Every valve is factory set for 120.5 F outlet temperature, with a 150F hot water inlet
temperature.*
Check:
Measure and note all site parameters (pressure, temperature, etc.) and check against the specifications of the
chosen valve. If the site conditions are outside those specified for the valve then they must be rectified prior to
installing the valve.
Valve MUST NOT be subjected to heat during installation as this may damage the valve internals.
Valve MUST NOT be fitted on steam-supplied systems, but to water systems only.
Valve MUST NOT be frozen. If the valve is installed in a situation where freezing is a possibility, then suitable
insulation must be fitted to prevent damage to the valve.
DO NOT use excess thread sealant (in liquid, tape or other form) as this may cause the valve to fail.
*NOTE: To ensure delivery of the desired mixed water temperature at the outlet the installer must adjust and verify the temperature at the outlet by
carefully following instructions on the following page.
Preset outlet temperature:
Outlet temperature range:
Temperature, hot supply :
Temperature, cold supply :
Temperature stability (nominal) :
Temperature differential :
(between

Hydrostatic pressure
Permitted supply pressure variation :
Flow rate @ 45psi pressure loss :
Flow rate, minimum:
Notes :
1.
As tested in accordance with ASSE1017.
2.
This is the minimum difference required between the valve outlet
temperature and the hot supply temperature to enable the valve to function
correctly and ensure shut-off of outlet flow in the event of cold supply failure.
3.
Maximum permitted variation in either supply pressure in order to control the
outlet temperature to within ±5°F. Excessive changes in supply pressures
may cause changes in outlet temperature.
