Failure to comply with all aspects of these instructions may result in
unsafe performance.
All installations must comply with relevant state and local authority
requirements.
Flush the system thoroughly before fitting the valve:
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.
Commission the valve:
Every valve is factory-set to a nominal temperature of 105°F. Every
must be adjusted on-site to ensure correct delivery of the
desired mixed water temperature , as installation conditions can vary
from site to site.
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 used on low pressure or instantaneous
heating systems.
• 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.
Leave a copy of these instructions with the client for future reference.
Recommend to the client that the valve be checked annually to ensure
its continued function.

Notes:
1. As tested in accordance with ASSE 1070.
2. This is the minimum difference required between the valve outlet
temperature and the hot supply temperature to ensure shut-off of outlet
flow in the event of cold supply failure, in accordance with ASSE 1070.
3.Maximum permitted variation in either supply pressure in order to
control the outlet temperature to with ±5°F .Excessive changes in supply
pressure may cause changes in outlet temperature, that exceed ±5°F.
