Installation Instructions

Rough-in Installation

Control valve assembly, piping
and fittings (Note: Illustrations below

show valve model without stops)

Reference as required: Page

Visual guide ....................................1

Dimensions illustration ................4

1) Determine wall thickness

■

Determine type of wall and wall
thickness where valve will be
mounted.

■ Consider whether to use mounting
plate by reviewing gure 2 below.

■ Skip ahead to Step 3 if mounting
plate is not used.

2) Attach valve mounting plate

Seat mounting plate against valve
assembly as illustrated in gure 1.

Figure 1 Mounting plate

3) Attach protective shield

■ Reference gure 2 to determine
whether shield is required.

■ Attach protective shield by snap
tting over end of valve spindle.

4) Install piping, fittings and

control valve

Piping and ttings not supplied

■ Control Valve
Install through cutout hole in wall
as specied in gure 2 below and
dimension illustration on page 4.

■ Showerhead (S on valve)
Pipe from outlet port on valve
marked S to showerhead
mounting arm location.

■ Hot & Cold Supply (H & C)
Pipe hot water supply to valve
inlet marked H and cold water
supply to valve inlet marked C.

■ Tub Spout (T on valve)
Pipe from outlet port on valve
marked T to tub spout.

Important! Do not
substitute Tub Spout with
restrictive ttings such as

PEX, CPVC or outlet accessories such

as a ledge spout, hose and spray that
would subject the valve to excessive
internal back pressure, otherwise
operation will be compromised.

5) Remove protective shield

If protective shield was attached
in Step 3 then remove shield
snap tted over the end of valve
spindle once valve is securely
installed and wall nish work
has been completed.

6) Adjust valve packing nut

Reference gure 3 below

■ Turn hot & cold supplies on.
Valve will not operate unless
both hot and cold water supply
pressures are turned on.

■ Place handle over end of control
spindle stem.

■ Adjust packing nut for positive
frictional resistance as handle
is rotated from shuto position
across adjustment range.

7) Flush system, check for leaks

■ Turn valve to the warm position
and run for a few minutes.

■ If system is dirty, remove valve
spindle in center of valve to
ensure proper ushing. (See
service instructions.)

■ Check for leaks around valve
assembly and all pipe ttings.

8) Set Temp Limit stop screw

Reference page 2, gure 3

e temperature limit stop screw
limits valve handle from being
turned to maximum position
resulting in excessive hot water
discharge temperatures.

Warning: Failure to
adjust Temp Limit stop
screw properly may result
in serious scalding.

■ Place handle on control spindle
stem and open valve to maximum
desired temperature.

■ Turn Temp Limit stop screw
clockwise until it seats.

Trouble Shooting Chart

Problem Cause Solution

Valve will not pass water.

Valve leaks when shut o.

Temperature control handle is
turned from cold to hot (or hot
back to cold) and volume from
spout or head is not constant.

Valve delivers sucient quantity of
cold, but little hot, or the reverse.

Temperature varies without
moving handle.

Valve delivery temperature reduces
gradually during use; handle must
be turned to hotter positions to
maintain constant temperature.

Valve delivers hot water when
initially opened. Water turns
colder as handle is rotated in
a counter-clockwise direction
toward the hot position.

When tub-shower valve’s diverter
handle is set in shower position a
pencil width stream of water runs
from the tub spout.

Both hot and cold water supplies are
not turned on.

Hot and cold washers are worn or
foreign matter (dirt, chips) is lodged
between washers and seat surfaces.

Pressure-balancing piston housed in
spindle assembly is restricted from free
movement by foreign matter.

Same as above Same as above

Same as above Same as above

Overdraw on hot water supply
(i.e. running out of hot water).

Valve is piped incorrectly (i.e. the hot
supply is piped to the valve’s cold inlet
and the cold supply is piped to the hot
inlet.)

Up to a pencil width stream of water
may ow from the tub spout to ensure
the water has been shut o at the main
valve only.

Turn on both supplies. Valve will not operate
unless both hot and cold water pressure is on.

1) Replace washers using control spindle
washer repair kit, p/n TA-9.

2) Replace hot & cold seats using hot/cold
seat repair kit, p/n TA-4.

1) Open valve halfway, remove handle and
tap spindle with plastic hammer.

2) Check water pressure balancing piston in
control spindle. See service instructions.

3) Replace control spindle, p/n TA-10.

Reduce maximum ow by using volume
control adjustment on valve or showerhead.
is will allow longer period of use before
overdrawing hot water supply.

If piping is accessible, correct connections to
the valve. If piping is not accessible, order
a reverse seat and tool kit, p/n T-108. Older
installations may also require replacing the
hot seat, hot/cold seat repair kit, p/n TA-4.

Service Instructions

Removing control spindle assembly

(Ref. parts assembly figure)

■ Shut o water supply to valve
and remove control valve handle

■ Replace both seats even if only
one appears worn.

■ Install and tighten both seats to
15 foot pounds of torque.

and dome cover.

■ Remove escutcheon plate by rst
removing escutcheon screws.

■ Turn valve’s control spindle to half
way position between minimum
and maximum rotation.

Important: Failure to

do this can damage
control spindle assembly.

■ Unscrew both spindle cap and

control spindle assembly.

Hot/Cold seat repair kit

Order p/n TA-4, T-35A and T-35B.

Installation requires both hot & cold
removal tools, p/n T-35A & T-35B.

■ Remove control spindle assembly.

■ Remove both seats with removal
tools.

Control spindle washer repair kit

Order p/n TA-9.

■ Remove control spindle assembly.

■ Remove cold washer by holding
spindle using valve handle and
unscrew cold washer retainer
using channel lock pliers.

■ Remove hot washer by removing
hot washer screw.

Checking water pressure
balancing piston

e perforated end of the control
spindle assembly houses the water

pressure-balancing piston which is
the heart of the valve.

■ Remove control spindle assembly.

■ Shake spindle assembly and listen
for clicking noise. Piston should
be free to slide back and forth the
full length of its travel.

■ If piston appears restricted then
do the following:

(1) Tap the handle or stem end of
the spindle against a solid object
to free the piston.

(2) Try soaking in household
vinegar and repeat step (1).

■ If unable to free piston, replace

control spindle, p/n TA-10.

Important:

Do not

attempt removal of
the piston.

Valve re-assembly

Reassemble by reversing above
procedures.

Aer the control spindle assembly
(TA-10) is threaded back into the
spindle cap assembly (T-12A)
ensure control spindle is rotated 1/2
turn clockwise from its maximum
counter clockwise rotational
position. Failure to do this will
damage assembly.
