Before You Begin (cont.)

NOTICE: Risk of product damage. This valve contains plastic and

rubber components. Do not sweat or braze directly to the valve

body. Do not apply excessive heat to the valve body when you

make solder connections. Do not apply ﬂux or acids directly to the

valve, as damage to the seals, plastic components, and trim ﬁnish

may result.

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.
