Powers Hydroguard PB410 Series User manual

The Series PB410 HydroGuard® is a pressure-compensating
mixer, which delivers a predetermined water temperature,
compensating for pressure fluctuations in the hot or cold
water supplies.
The Series PB410 HydroGuard® features heavy, cast brass
construction a poppet-type equalizing valve as part of a
replaceable cartridge. The poppet-type construction offers
a distinct advantage in that it will not stick because of lime
build-up or foreign particles in the supplies. The adjustable
metal-to-metal temperature limit stop prevents accidental
scalding caused by over adjustment of the handle. It also
features integral check stops, back-to-back and shallow wall
installation capability.
Description n
The Series PB410 HydroGuard® is recommended in showers
and bath and shower installations for motels, hotels, dormito-
ries, health clubs and high rise apartment buildings.

Product Specification
IS-P-PB410
Model PB41700000
Hot and cold water enter their respective ports and the
pressures are equalized through the action of the balance
poppet. The entire balancing poppet assembly is contained
in a Celcon cartridge. After the hot and cold pressures are
equalized, they are mixed by the action of a mixing plate. As
the temperature adjustment stem is rotated from shutoff to
maximum hot water temperature, the mixing plate passes
the required proportion of hot and cold water to produce the
control point. With the adjustment stem in its full clockwise
position, shutoff is obtained by closing both supplies.
The temperature limit stop allows the user to set the maxi-
mum discharge temperature. This mixer does not recognize
supply water temperature changes, so any variation in the
water temperature will affect the control point and the maxi-
mum temperature setting.

Note: Installation should be in accordance with
accepted plumbing practices. Flush all piping thor-
oughly before installation.
1. Position mixer 115⁄16" ± 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.

12. The high-temperature limit stop is located at the center of
the bonnet. To adjust the temperature, unscrew two bon-
net screws halfway. To increase the temperature, rotate
the stem counter-clockwise to the required temperature
using the handle for leverage. Do not place pliers or chan-
nel locks on the spline of the stem. Tighten the two bonnet
screws. To decrease temperature, turn the stem clockwise
to the required temperature. Rotate the limit stop with the
help of small flathead screwdriver clockwise until it touch-
es the stem stop. Tighten the two bonnet screws. Close
valve and open it to verify setting (See Figure 5).

Always verify the maximum temperature setting of the valve
when any changes are made. This should also be checked
as a part of a facilities maintenance/safety program.

What to look for if:
• The flow of water is less than desired.
a. Valves upstream from supply not fully open.
b. Low supply pressures.
c. Accumulation of lime deposits in hot water pipes, restricting
the flow of hot water.
d. Showerhead clogged.
e. Checkstops may not be fully open.
f. Low supply temperature (Hot Water).
• Flow of water is completely shut off.
a. Valves upstream from supply completely closed.
b. Failure of hot or cold water supply pressure. The
HydroGuard® is constructed to restrict the flow of water on
hot or cold water supply failure.
c. Checkstops closed.
• Flow is untempered hot or cold water.
a. The water supplies are connected to the wrong ports.
b. Check for foreign material that may be clogging the car-
tridge.
• Flow of water continues when HydroGuard® is
shut off.
a. Worn shutoff discs. Replace cartridge.
b. Scratched mixing plate. Replace Bonnet/Stem Kit.
c. Erosion. Contact a Powers applications engineer to order
replacement parts.
• Maximum temperature is too low.
a. Accumulation of lime deposits in hot water pipes, which
restricts the flow of hot water.
b. The concealed maximum temperature limit stop is not at its
maximum adjustment. Set the maximum temperature limit
stop.
c. Hot water temperature is too low.
