Powers HydroGuard 400 Series Anleitung zur Verwendung
The Hydroguard 400/410 pressure balancing valve insures
safety to the bather upon hot or cold water supply pressure
failure or change. The internal balance chamber forces the
hot or cold water supply pressure to be equalized should
either pressure fail or change. To ensure correct repair
parts are installed, determine valve model by referring to
bonnet label (see Figure 1). Once model number is deter-
mined, refer to appropriate chart to ensure correct kit has
been supplied. Since kits contain parts for multiple
models, discard extra parts.
Replace Balance chamber if…
• The discharge water temperature is variable or untempered.
• The valve leaks after it is completely shut off.
Balance Chamber Removal:
TO REMOVE THE BALANCE CHAMBER, using a bal-
ance chamber extraction tool (Part No. 401-202) is highly
recommended. To use the extraction tool, follow instruc-
tions below:
a. Insert hooked ends of extraction tool into HOT and
COLD outlet ports of the balance chamber (see Figure
2).
b. Insert screwdriver down through end of extraction tool.
c. Place a wood or plastic block (do not use metal)
between screwdriver and valve body. Firmly ease
screwdriver away and downward, using wood for
added leverage as cartridge is gradually pulled out.
Balance Chamber Installation:
1. Apply a small amount of silicone supplied to inner surface
of valve body and inlet “O”-rings of balance chamber.
2. Align chamber and valve body inlet holes.
3. Slowly push chamber in, being very careful not to pinch
side “O”-rings (item 5A in figures 5 and 6).
Replace Gasket and Disks if…
• Flow continues after mixer is turned off.
• Stem or handle is damaged.
• Water leaks at stem and/or bonnet.
Gasket and Disc Replacement:
1. Replace all gaskets and discs according to the dia-
grams as shown in figures 5 and 6. Use silicone gel
provided on all “O”-rings and related surfaces. Never
use grease.
2. The number of flat washers required for installation on
stem varies with each model. Refer to Figure 3 when
replacing the washers.

Replace Stem and Plate if…
• Flow continues after mixer is turned off.
• Water leaks at stem and/or bonnet.
Stem and Plate Replacement
1. FOR STANDARD INLETS: Place the plate
directly on top of the balance chamber
(see Figure 4 for proper orientation of
plate).
2. The flat notch on the splined stem must
FACE the outlet port of the valve body for
standard inlets (cold water entering COLD
inlet port).
3. FOR REVERSED INLETS: (cold water
entering hot inlet port), the flat notch on the
splined stem must face AWAY FROM the
outlet port. See Figure 4A for proper orien-
tation of plate.

Gradually rotate stem counterclockwise to get desired
maximum water temperature. (Maximum Temperature
Stop will rotate long with the stem when the stem is
rotated).
b. Once stem has been rotated to desired temperature,
slide adjustment stop clockwise until fin on adjustment
stop touches the maximum temperature stop.
c. While holding adjustment stop in place, tighten adjust-
ment stop screw.
d. Replace handle. Confirm maximum temperature has been
set properly by operating the valve using the handle.
Caution: Adjustment stop must be present for proper
operation.
