Before You Begin (cont.)
The thermostatic mixing valves do not have an integral aspirator.
For installations that use a bath diverter spout, you must install a
twin ell (K-9663) with integral aspirator between the valve and
the bath spout. If these thermostatic mixing valves are installed
without an aspirator, it will cause water to flow from the shower
and bath spout at the same time.
Determine the correct drain size and capacity for your
installation. If two thermostatic mixing valves are used together,
water volumes between 18 and 30 gal/min (60 and 114 l/min) or
more are possible, depending upon the water supply pressure.
Determine the correct water heater size and capacity for your
installation. A typical shower installation uses an approximate
mix of 75% hot water and 25% cold. A custom shower application
using three 2.5 gal/min (9.5 l/min) showerheads can use about 45
gallons (170 liters) of hot water in 8 minutes. Choose a water
heater large enough for your installation.
The valve is calibrated to 104°F (40°C) at the first stop position.
The maximum temperature limit stop is positioned so the outlet
water temperature does not exceed 120°F (49°C).
The factory calibrated pressure for hot and cold water inlets is
43.5 psi (300 kPa). The factory calibrated hot water supply
temperature is 149°F (65°C) and the cold water supply
temperature is 59°F (15°C).
If the inlet conditions differ from those used during factory
calibration, it may be necessary to re-calibrate the valve after
installation. The installer must check the mixed flow
temperature after installation and adjust the valve as needed
according to the instructions.
If possible, flush all piping thoroughly before installing the valves
to prevent early clogging of filter screens.
