Installation
CAUTION
When these installation, operation and service
instructions are not followed, TempControl functionality
and service life will be greatly impaired.
All TempControl installations must have a
thermometer and shut off valve in the tempered water
outlet (as shown in diagrams) for proper trouble
shooting service.
Technical Assistance and Sizing
For assistance and technical support in sizing and
selection of the proper TempControl valve or system,
consult the Symmons TempSize™ computer sizing
software, your local representative or Symmons
Customer Service Department at 1-800-SYMMONS.
TempControl Location
An underlying premise of thermostatic water controller
installations is an acknowledgement that thermostatic
mixing valves will not operate properly when the hot
and cold supplies serving such valves are subjected
to pressure disturbances when owing less than full
capacity. In a correctly designed mechanical room, the
supply pressures are stable and not subject to pressure
disturbances. As a result, when a TempControl valve is
indicated as being located in the mechanical room, a
Hi-Low system will not be recommended.
When the valve’s location is indicated as being outside
of the mechanical room, it is assumed that there is
a potential for pressure uctuations in the hot and
cold supply lines servicing a TempControl valve and a
Hi-Low system will automatically be recommended.
Note: If the system is designed so that the TempControl
valve is not subjected to high-low ow demand, even
though it is located outside the mechanical room, a
single TempControl valve will operate properly.
Installation Tips
All piping should be thoroughly ushed before TempCon-
trol is installed. The TempControl can be installed in any
position as long as Hot Water is connected to “H” port
and Cold Water is connected to “C” port. Close service
stops on TempControl, remove cartridge, (see page 11
for Cartridge Removal & Replacement section), turn on
water supply and open stops wide to thoroughly ush
piping before putting valve in service. TempControl is set
at factory to deliver approximately 100° F.
