Reference gure 3

■ Turn hot & cold supplies on.
Valve will not operate unless both hot

and cold water supply pressures are on.

■ Place handle over control spindle stem.

■ Adjust packing nut for positive
frictional resistance as handle is

7) Flush system and 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

8) Set Temp Limit stop screw

Reference gure 3

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

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

■ Turn limit stop screw clockwise until
it seats.

Note:
devices on control valve outlet or devices that
do not allow the valve to ow at least 1.5 gpm.

Do not install positive shut-o

Warning:

limit stop screw properly may
result in serious scalding.

Trouble Shooting Chart

Problem Cause Solution

Valve will not pass water.

Valve leaks when shut o.

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.

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.

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.

Service Instructions

Removing control spindle assembly

(Ref. parts assembly figure)

■ Shut o water supply to valve and
remove control valve handle 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.

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

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.

Same as above Same as above

Same as above Same as above

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

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

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.)

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.

■ Replace both seats even if only one
appears worn.

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

Control spindle washer repair kit

Order p/n TA-9.

■ Remove control spindle assembly.

■ Remove cold washer by holding spindle

■ 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.

using valve handle and unscrew cold
washer retainer using channel lock

pliers.

■ Remove hot washer by removing hot
washer screw.

Important:

Do not attempt

removal of the piston.

■ Unscrew both spindle cap and control

spindle assembly.

Checking water pressure
balancing piston

e perforated end of the control spindle

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.

assembly houses the water pressure­balancing 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.

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.
