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

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.

Symmons Industries, Inc. 31 Brooks Drive ■ Braintree, MA 02184 ■ (800)796-6667, (781)848-2250 ■ Fax (800)961-9621, (781)664-1300

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.
