3. INSTALLATION

CONSTRUCT FRAMING AND INSTALL

ROUGH PLUMBING

Determine the desired location for the valve according to

the rough-in information on Page 3, and construct

suitable stud and support framing.

Use 3/4” nominal copper tubing and fittings throughout

this installation. Smaller diameter piping upstream or

downstream of the valve will reduce the performance of

the valve.

INSTALL VALVE

Flush the hot and cold water supply lines to remove any

debris.

CAUTION: Risk of product damage. This valve

contains plastic and rubber components. 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 and

plastic components may result. Do not apply

petroleum-based lubricants to the valve components,

as damage may result.

Use thread sealant, and connect the 3/4” hot and cold wa-

ter supply lines to the valve inlet ports. Install water ham-

mer arrestors in the supply lines. The inlet ports are

marked “HOT” and “COLD”, and must be connected to

the correct water supply lines to ensure proper valve func-

tion. Make sure the integral volume control/shut-off valve

on the K-401 is on top.

Connect the water outlet lines to the valve ports. Use a

3/4” plug for any unused outlet port.

The plaster guard is attached to the face of the mixing

valve with two screws. Do not remove the plaster guard

until instructed. Use the plaster guard to determine the

depth of the valve in the wall, and to trace the cut-out line

in the wall material. The finished wall surface must be

within the MIN. – MAX. depth shown on the plaster guard.

Secure the water supply piping to the support framing.
