Before You Begin (cont.)
NOTICE: Risk of product damage. Do not apply petroleum-based
lubricants to the valve components, as damage may result.
NOTICE: Risk of product damage. Inlet and outlet threaded joint
connections should be made with plumbers PTFE tape or liquid
sealant. Oil-based, non-setting compounds should not be used.
NOTICE:
Do not force the handle in any direction. Forcing the
handle will damage the valve.
Observe all local plumbing and building codes.
Shut off the main water supply.
Inspect the supply piping for damage. Replace as necessary.
The bottom port of the thermostatic mixing valve is intended for
use as a bath filler only. If a bath spout is not used with this
product, cap the bottom port.
The K-2972 and K-2975 thermostatic mixing valves do not contain
an integral volume control/shut-off valve. You must install a
separate volume control/shut-off valve (K-2974 or K-2977)
downstream of any used valve outlet.
The K-2973 and K-2976 thermostatic mixing valves contain a
single volume control shut-off valve for controlling the water flow
through the shower outlet. When plumbing to the valve’s bath
outlet, you must install a separate volume control shut-off valve
(K-2974 or K-2977) downstream from the bath outlet.
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 gpm (60 and 114 lpm) or more
are possible, depending upon the water supply pressure.
