Adjusting the Rotational Limit Stop

IMPORTANT:

The Rotational Limit Stop is used to limit the

amount of hot water available such that, if set

properly, the user will not be scalded if the han-

dle accidentally is rotated all the way to “hot”

when a person is showering or ﬁlling a tub. The

ﬁrst position allows the LEAST amount of hot

water to mix with the cold water in the system.

In the ﬁrst position the water will be the coldest

possible when the handle is turned all the way

to hot. As you move the Rotational Limit Stop

clockwise, you progressively add more and

more hot water in the mix. The last position will

result in the greatest amount of hot water to

the mix, and the greatest risk of scald injury if

someone accidentally turns the valve handle

all the way to the hot side while showering or

ﬁlling a tub.

WARNING: In some instances, setting the

Rotational Limit Stop in the hottest position

(full clockwise) could result in scald injury.

It is necessary to adjust the Rotational

Limit Stop so that the water coming out

of the valve will not scald the user when

the handle of the valve is rotated to the

hot side.

• According to the majority of industry stan-

dards, the maximum allowable temperature of

the water exiting the valve is 120°F (Your local

plumbing codes may require a water tempera-

ture less than 120°F).

• The Rotational Limit Stop may need to be re-

adjusted seasonally if the inlet water tempera-

ture changes. For example, during the winter,

the cold water temperature is colder than it is

during the summer which could result in vary-

ing outlet temperatures. A water temperature

for a comfortable bath or shower is typically

between 90°F - 110°F.

• Use a thermometer to set the rotational limit

stop. Do not rely on the digital display tempera-

ture. There may be up to a 7° F difference in

temperature of the water coming out of the

spout or showerhead as compared to the

reading on the display.

• Run the water so that the cold water is as

cold as it will get and hot water is as hot as

it will get. Place the handle on the stem and

rotate the handle counterclockwise until the

handle stops.

• Place a thermometer in a plastic tumbler

and hold in the water stream. If the water

temperature is above 120°F, the Rotational

Limit Stop must be repositioned

counterclockwise to decrease valve outlet

water temperature to be less than 120°F

or to meet the requirements of your local

plumbing codes.

• To adjust the temperature of the water

coming out of the valve, remove the o-ring

and pull the disc back to a position where it is

possible to remove the Rotational Limit Stop

and readjust the teeth engagement position to

the desired temperature. Counterclockwise will

decrease the outlet temperature, clockwise will

increase the outlet temperature. Temperature

change per tooth (notch) could be 4° - 16°F

based on inlet water conditions. Repeat as

necessary. Push disc until fully seated and

replace o-ring.

WARNING: Failure to re-install disc and

o-ring after setting Rotational Limit Stop

could result in scald injury.

• MAKE SURE COLD WATER FLOWS

FROM THE VALVE FIRST. MAKE SURE

WATER FLOWING FROM THE VALVE

AT THE HOTTEST FLOW POSSIBLE

DOES NOT EXCEED 120°F OR THE

MAXIMUM ALLOWED BY YOUR LOCAL

PLUMBING CODE.

Disc

Faucet leaks from tub spout/showerhead:

SHUT OFF WATER SUPPLIES.

Replace seats and springs–Repair

Kit RP4993. Check condition of lower O-rings and

replace if necessary RP14414. See Helpful Hints

1, 2, & 3.

If leak persists:

SHUT OFF WATER SUPPLIES.

Replace valve cartridge RP46074.

See Helpful Hints 1, 2, 3 & 5.

Unable to maintain constant water temperature:

Replace valve cartridge RP46074 or follow

instructions in Helpful Hints 1, 2, 4 & 5.

Helpful Hints:

1. Before removing valve cartridge assembly for any

maintenance, be sure to note the position of the

rotational limit stop on the cap. The valve cartridge

assembly must always be put back in the same

position. BE SAFE! After you have ﬁnished the

installation, turn on valve to make sure COLD WATER

FLOWS FIRST.

2. To remove valve cartridge from body, shut off

water supplies and remove handle and bonnet

nut. Do not pry the valve cartridge out of the body

with a screwdriver. Place handle on stem and rotate

counterclockwise approximately 1/4 turn after the stop

has been contacted. Lift valve cartridge out of body.

3. To remove seats and springs, remove valve

cartridge. Separate cap assembly from the

housing assembly by rotating the cap assembly

counterclockwise 90

(degrees). Separate cap and

housing assemblies. Remove seats and springs and

replace. Place the largest diameter of the spring

into the seat pocket ﬁrst and then press the tapered

end of the seal over the spring. Reassemble valve

cartridge and replace in body following instructions

given in 1 above.

4. If the water in your area has lime, rust, sand or

other contaminants in it, your pressure balance

valve will require periodic inspection. The frequency

of the inspection will depend on the amount of

contaminants in the water. To inspect valve cartridge

remove it and follow the steps in note 1 above.

Turn the valve to the full mix position and shake the

cartridge vigorously. If there is a rattling sound, the

unit is functional and can be reinstalled following

instructions given in note 1 above. If there is no rattle,

replace valve cartridge EP78407.

5. Push disc until fully seated. See page 10 for

more details.
