Powers PB410 Series Pressure Balancing Mixing Valves - Pressure Balancing Mixing Valve - Manual (Page 2)

Note: Installation should be in accordance with
accepted plumbing practices. Flush all piping thor-
oughly before installation.
1. Position mixer 1
15 ⁄
16
" ± 1 ⁄
2
" [49mm ± 13mm] from inlet center to
finished wall surface. The tub outlet port is marked "TUB" and
should face down. Facing front of mixer, connect hot water to
left side and connect cold water to right side. The valve has
"C" and "H" cast into the body near the appropriate inlet ports.
2. 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 instruc-
tions a–f below:
a. Connect cold inlet to hot port ("H") and hot inlet to cold port
("C"). Note: 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 check stops.
c. Loosen both temperature limit screws.
d. Remove bonnet & stem
e. Turn stem 180º, making sure notch or the stem is facing
downwards.
f. While holding stem, tighten bonnet.
Note: Be certain that valve opens in full cold!
g. Hot and Cold inlets should be re-identified for reversed
inlets to avoid confusion during future maintenance.
3. For tub and shower installations (see Figure 2). Pipe bottom
outlet port "TUB" directly to the diverter tub spout. The mixer
body is designed to operate without the use of a twin ell. Pipe
top outlet port to the showerhead.
4. For shower only installation (see Figure 3) pipe top outlet port
directly to the showerhead and plug bottom port.
5. Rough-in guide installation…
a. When piping installation is completed and before doing the
finished wall, slide rough-in guide onto the mixer stem and
press fit into place (See Figure 4).
b. The rough-in guide will ensure the proper size opening for
mixer and check stop shutoff and repair accessibility, as
well as protect the chrome-plated sleeve from damage dur-
ing drywall and tile installation.
6. After wall is completed, remove rough-in guide.
7. Attach indicator plate gasket to the back of the dial plate
making sure horizontal holes match horizontal holes. Indicator
plate locator hole matches diagonal hole on the plate. Peel off
backing of dial gasket and attach to the inside top edge of the
dial plate. Gasket should be approximately 1⁄16" beyond the
plate edge.
8. Install the dial plate with the screws provided.
9. Snap on the indicator plate. Guide on the back of the plate
goes into the locator hole.
CAUTION: Indicator plate must be installed before
sleeve.
10. Install sleeve O-ring in the bonnet groove. Slide sleeve on the
bonnet.
11. Install handle and tighten the setscrew.
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 mechanism. By following this recommendation,
you will be able to solder the valve without removing either the
cartridge or the checkstop internals. If either brazing or resis-
tance (electric) solder is to be used, all valve internals must be
removed.
