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.

Thermistor Assembly
7. Locate and insert the thermistor (temperature probe) into the supplied compression outlet. See Figure 3 for the probe depth. Improper
installation of depth probe can result in imprecise temperature readings. Firmly tighten to prevent leakage. Do not hang trim plate on
wall using temperature probe wire as this could cause damage to
probe. Pressurize and test the system to verify zero leakage.
8. When piping installation is completed and before doing the finished
wall, slide rough-in guide on to the valve stem and press fit into place
(Figure 4). The rough-in guide will ensure the proper size opening for
valve, shutting off checkstops and and repair accessibility.
9. Attach indicator gasket to the back of the trim plate making sure
diagonal holes on the gasket matches diagonal holes on the trim
plate and locator hole matches the top hole on the trim plate. Peel
off backing of the trim plate gasket and attach to the inside top edge
of the trim plate.
10. Install trim plate.

Safety Guidelines n
Adherence to these guidelines and recommendations promotes safe
product use and ensures proper valve performance.
1. Thermostatic valves are control devices which must be cleaned
and maintained on a regular basis. Powers specifies periodic maintenance at least once a year or immediately after any changes are
made to the plumbing system. Annual cleaning is recommended,
however, frequency of cleaning depends on quality of local water
conditions.
2. 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.

Troubleshooting n
What to look for if:
• The maximum temperature cannot be obtained:
1) Lime deposits may have accumulated in the hot water pipes,
restricting the hot water supply.
2) The hot water supply temperature may be too low.
3) The temperature limit stop may be set too low. Remove handle
and re-adjust temperature limit stop (refer to step 9 of installation
instruction section).
• Flow of water is less than desired:
1) The upstream supply valves may not be fully open.
2) The inlet supply pressure(s) may be low.
3) The showerhead may be clogged.
• The valve opens with hot water ow rather than cold water ow:
1) The inlet water supplies are connected to the wrong ports or cartridge is installed improperly (see section on reversed inlets).
Parts List n
4
The tempered water is too cold, although cartridge has been replaced,
or the hot water temperature is below 115°F:
1) Raise the temperature of the hot water supply.
Flow of water is completely shut off:
1) The upstream supply valve may be completely closed.
2) The hot or cold water pressure may be failed. The valve is
designed to close down upon cold water supply pressure failure.
3) The checkstops may be closed. Open checkstops by turning the
adjustment screw fully counterclockwise.
Temperature does not display:
1) Replace battery
