Description n

The Series e700 HydroGuard T/P automatically mixes hot and
cold water to deliver blended water within a specified range.
Using an advanced thermal actuator, the Series e700 quickly
compensates for temperature fluctuations induced by water
temperature and pressure changes. In the event of cold
water failure, the thermostatic motor virtually shuts off the
flow of hot water. HydroGuard T/P meets the most stringest
performance criteria for temperature and pressure changes,
defined by ASSE 1016 (Type T/P).

Featuring heavy, cast-brass construction and an adjustable
brass to brass high limit temperature stop, self-contained

cartridge, corrosion resistant internal component, integral
checks, and back to back shallow wall installation capabil­ity. All parts of the e700 Series valve are accessible from
the front of the valve. All Series e700 valves open in the cold
water position to ensure maximum bather safety and comfort.

The accuracy, reliability and water economy of the Series
e700 HydroGuard T/P make it preferable for applications that
require precise, consistent water
control: showers, baths, hospital hydrotherapy and
residential areas. All e700 valves meet the Americans with
Disabilities Act (ADA).

All HydroGuard T/P Series e700 combination mixing valves
meet above performance specifications based on typical
operating conditions as stated in ASSE 1016 (45 psi pressure
differential, hot water supply between 140°-180°F (60°-82°C),
cold water supply less than 70°F (21°C).

If your operating conditions vary from those stated in the
standard, performance may vary as well. Consult your local
sales representative or a Powers factory engineer to discuss
your specific application. All Powers thermostatic mixing
valves perform to the requirements of standards ASSE 1016
and CSA B125.

Operation n

Hot and cold water enter respective ports in the valve and mix
in a chamber containing an advanced thermal actuator (refer to
cutaway view). This actuator controls the position of the plunger
and temperature.

Rotating the adjustment handle repositions the plunger in the
cartridge assembly to produce the desired temperature. The
mixed water passes over the shut-off disc to the outlet. If the
hot or cold supply water temperature or pressure changes, the
thermal actuator will contract or expand. This movement reposi­tions the plunger to maintain the desired temperature. With the
adjustment handle in full clockwise (OFF) position, the shut-off
disc closes the mixing chamber from the outlet.

A high temperature limit stop restricts the movement of the
control handle. All HydroGuard T/P e700 valves are factory set
to deliver tempered water up to 110°F [43°C] with equal supply
pressures, with hot water temperature 140°F [60°C], cold water
temperature 60°F [15.6°C].

NOTICE

The handle rotation stop must be adjusted by the installer.

!

WARNING

Maximum Temperature Setting/Handle Rotation Stop
The handle rotation setting must be adjusted to limit the distance

the user can rotate the handle towards the full hot water posi­tion.

!

CAUTION

Any repair or modification of the valve may affect the high tem­perature setting. The maximum

temperature setting must be checked by the installer before use.

1. Remove the valve handle and sleeve.

2. Adjust the valve to the desired maximum outlet temperature
[110°F (43°C) max]. Screw on the high temp. limit stop until it
touches the stem shoulder.

3. Turn the stem clockwise until the water stops.
Open valve to full hot position and verify maximum outlet
temperature setting.

4. Place sleeve "O" Ring on the bonnet shoulder.
Slide sleeve over the "O" Ring until it stops.

5. Replace handle.

Reversed Inlets
Valve is factory-set for standard inlets If reversed inlets are

required due to back-to-back installation (Cold water supply on
the left and Hot water supply on the right), follow instructions a
through d below:

a. Connect cold inlet to hot port (“H”) and hot inlet to cold port

(“C”).

NOTICE

Do not turn valve upside down. If valve is upside down, water
will not flow properly through tub spout or showerhead.

b. Turn water off with checkstops, remove bonnet and

cartridge.

c. Reinstall cartridge. “H” on the cold side of the valve body

and “C” should be on the hot side of the valve body.

d. Reinstall bonnet with high temperature limit stop on it.

NOTICE

Be certain that valve opens in full cold!
e. Hot and Cold inlets should be re-identified for reversed inlets

to avoid confusion during future maintenance.

Safety Requirement - All Models n

!

WARNING

Need for Periodic Inspection: Periodic inspection by a licensed
contractor is recommended. Corrosive water conditions, tempera­tures over 200°F, unauthorized adjustments or repair could render
the valve ineffective for service intended. Regular checking and
cleaning of thermostat assembly helps to assure maximum life
and proper product function. Frequency of cleaning depends upon
local water conditions.

Adherence to these guidelines and recommendations promotes
safe product use and ensures proper valve performance.

Troubleshooting n

What to look for if:

• The maximum temperature cannot be obtained...

a. Lime deposits may have accumulated in the hot water pipes,

restricting the hot water supply.
b. The hot water supply temperature may be too low.
c. The handle rotation setting may be too low. Remove valve

handle, and readjust the high temperature limit stop (see

page 2).

• Flow of water is less than desired…

a. The upstream supply valves may not be fully open.
b. The inlet supply pressure(s) may be low.
c. The showerhead may be clogged. Remove and clean the

showerhead.
d. The checkstops may be clogged. Refer to Preventive

Maintenance section.

!

CAUTION

The high temperature limit stop setting must be adjusted to limit
the distance the user can rotate the handle towards the full hot
water position.

NOTICE

Position the e700 valve as close as possible to outlet fixture to
avoid waste of energy and water.

• The valve opens with hot water ow rather than cold water
ow...

a. The inlet water supplies are connected to the wrong ports

or cartridge is installed improperly. See section on “Reverse
Inlets”.

• The tempered water is too cold, although cartridge has been
replaced, 0R the hot water temperature is below 115°F...

a. Raise the temperature of the hot water supply.

• Flow of water is completely shut off...

a. The upstream supply valves may be completely closed.
b. The hot or cold water supply pressure may have failed. The

e700 valve is designed to close down upon cold water supply
pressure failure.

c. The checkstops may be closed. Access the checkstops and

open by turning the adjustment screw fully counterclockwise.
