Powers 470 Series VisuGuard Pressure-Balancing Tempering Valve with LCD Temperature Display - Manual

Note: Installation should be in accordance with accepted
plumbing practices. Finish all piping thoroughly before
installation.
VALVE PIPING
1. Facing the front of the mixer, connect hot water supply to
the left side and cold water to the right side of the valve.
These supply inlets must be piped correctly or the valve
will not mix properly (inlets are labeled on the bonnet). If
supply lines are reversed, see “mixing plate rotation.”
2. All VisuGuard LCD mixers are supplied for 4-port applica-
tions and can be modified for 3-port applications by
using the included
5 ⁄
8
″ sweat plug. Refer to “Dimensional
Data” to determine proper installation.
3. Do not remove the rough-in guide; you will use it to posi-
tion mixer to the proper depth within the wall later.
4. If copper tubing is used, use flared fittings to connect tub-
ing to mixer. The heat generated during the solder opera-
tion could damage the internal parts of the mixer. Inlet
checkstops for direct sweat connections are available.
If flared fittings or checkstops cannot be used,
remove the balance chamber before soldering (see
balance chamber removal).
TRIM PLATE / HANDLE ASSEMBLY
Refer to exploded view to identify parts.
1. Using the rough-in guide to aid in cutting the proper
access hole into the finished wall.
2. Apply the adhesive trim plate gasket to the inside edge
of the trim plate. Proper application results in approxi-
mately
1 ⁄
4
″ gasket compression against finished wall.
3. Remove rough-in guide.
4. Locate and insert the thermistor (temperature probe)
into the supplied compression fitting at the mixer outlet.
See proper probe depth below (Figure 1). Improper
installation of depth probe can result in imprecise tem-
perature readings. Firmly tighten to prevent leakage.
5. Apply trim plate to wall (valve handle inserted through
trim). Do not hang trim plate on wall using temperature
probe wire as this could cause damage to probe.
6. At this point it is wise to pressurize and test the system
to verify zero leakage and set maximum temperature
settings prior to finishing the trim application.
7. Maximum temperature setting adjustment: To change
setting, remove splined stop by slipping O-ring up on
stem. Rotate temperature adjustment stem to desired
maximum temperature. Position splined stop on the
adjustment stem so that it contacts the bonnet stop.
Replace O-ring.
