1. All installations must be done out by licensed professionals.
2. You must ensure compatibility of the installation. Example: temperature of hot water- Marked “H“,
cold water inlet –marked “C” and mixed outlet – marked with a directional arrow.
3. The mixing valve may be installed in any position.
4. Any inconsistency between these instructions and any specific instruction, bylaw or code issued
by local authorities must be referred back to Heat Transfer Products Technical Support Department
prior to any installation taking place.
5. During startup; you must ensure that the valve is set to the desired temperature (The mixing valve
is preset to 130°F). If the valve temperature needs to be adjusted, please refer to the mixing valve
Instructions and/or the following settings.
Mixing Valve Specification
Max. Hot Water Inlet Temperature 210°F
Min. Cold Water Inlet Temperature 39°F
Inlet Pressure 200 PSI
Outlet Water Temperature Range 85°F – 150°F
Min Temperature Differential 20°F
(Between Hot Supply and Outlet)
Performance –
CV – 1/2” 3.3
Max Flow – 1” 24 gpm
The mixing valve maintains a constant outlet temperature of +/– 5˚ F given limited variation of water
inlet temperature and pressure.
Note: At low flow operation, the outlet temperature may vary slightly more.
Differential pressure at the valve inlet should be within a 5 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 5 to 1 ratio please call Heat
Transfer Products Technical Support Department.
