Description n
The VisuGuard LCD T/P series automatically mixes hot and cold water to deliver blended
water within a specified range. Powerful advanced thermal actuator quickly compensates
for both temperature and pressure fluctuation. In the event of cold water failure, the thermostatic actuator virtually shuts off the flow of hot water. The VisuGuard LCD T/P meets the
most stringent performance defined in ASSE 1016 Type T/P standard. The VisuGuard LCD
T/P comes complete with battery operated LCD temperature display in Farenheit or Celsius
for use in bath & shower applications.
Battery and temperature display are housed in an easy-access, watertight enclosure. The
accuracy and reliability of the F727 & C727 VisuGuard LCD T/P make it preferable for applications that require precise, consistent water control for showers, baths, hospital hydrotherapy and residential areas. Both the F727 & C727 VisuGuard LCD T/P meet the American
with Disabilities Act (ADA).

Operation n
Hot and cold water enter respective ports in the valve and mix in a chamber containing
an advanced thermal actuator (see Figure 1). This actuator controls the position of the
plunger and temperature. Rotating the handle repositions the plunger in the cartridge
assembly to produce the desired temperature. The mixed water passes over the shutoff
disc to the outlet. If the hot or cold supply water pressure or temperature changes,
the thermal actuator will contract or expand. The movement repositions the plunger to
maintain the desired temperature.
A high temperature limit stop restricts the movement of the handle. All F727 & C727
VisuGuard LCD T/P valves are factory set to deliver tempered water up to 110°F (43°C)
with equal pressure, with hot water temperature 140°F (60°C) and cold water temperature 60°F (16°C).

FAILURE TO COMPLY WITH PROPER INSTALLATION AND
MAINTENANCE INSTRUCTIONS COULD CONTRIBUTE TO
THE VALVE FAILURE, RESULTING IN INJURY AND/OR DEATH.
TO ENSURE THE ACCURATE AND RELIABLE OPERATION OF
THIS PRODUCT, IT IS ESSENTIAL TO:
• Properly size each valve based on the individual application.
• Properly design the recirculation system to minimize pres-
sure and temperature variations.
• Conduct an annual maintenance program to ensure proper
operation of all critical components.
• Check outlet temperature to ensure it does not exceed 110°F
(43°C). Make sure temperature limit stop is properly re-set
to maximum 110°F (43°C) following valve maintenance or
repair. Tampering with limit stop in any way may result in
scalding temperature causing serious bodily harm and/or
death.
Periodic Inspection: Corrosive water conditions, temperatures over 210°F, unauthorized adjustments or repair could
render the valve ineffective for the service intended. Regular
checking and cleaning of the valve's internal components
and checkstops helps assure maximum life and proper
product function.

1. Flush all piping before installation
2. Installation and field adjustment are the responsibility of the installer
and shall be carried out in accordance to the following steps.
3. Position mixer 1-5/8" +/- 1/4" (41mm +/- 6mm) from inlet center of fin-

ish valve surface. The tub outlet port is marked "TUB" and should
face down. Facing front of the mixer, connect hot water to left side
and cold water to right side. The valve has "C" and "H" cast into the
body at the appropriate inlets ports.
!
CAUTION
When soldering during installation process, do not heat the valve any
higher than the temperature required to flow solder. Excessive overheating of the valve may cause damage to the cartridge and the checkstop internals. If either brazing or resistance (electric) solder is to be
used, all valve and checkstop internals must be removed.

WARNING
Figure 3
Use caution when soldering. Protect yourself and others. FUMES
AND GASES can be hazardous to your health. HEAT RAYS (INFRARED RADIATION) from flame or hot metal can injure eyes.
4. 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 1 to 5 below:
1) Connect cold inlet to hot port (H) and hot inlet to cold port (C).
Note: Do not turn valve upside down, water will not flow properly
through tub spout or showerhead.

2) Turn water off with checkstops, remove bonnet and cartridge.
3) Reinstall cartridge. "H" on the cold side of the valve body and "C"
should be on the hot side of the valve body.

4) Reinstall bonnet with the high temperature limit stop on it.
Note: Be certain that valve opens in full cold.
5) Hot and cold inlets should be re-identified for reversed inlets to
avoid confusion during future maintenance.
5. See Figure 2, for proper piping arrangement.
6. For both shower only and shower/tub arrangements, top outlet "S" is
plugged.
