DESCRIPTION
The Series 410 Hydroguard is a pressure compensating mixer
which delivers a predetermined water temperature, compensating for pressure fluctuations in the hot or cold water supply.
The Series 410 Hydroguard features a poppet-type equalizing valve as part of a replaceable cartridge. The poppet-type
construction offers a distinct advantage, it will not stick
because of lime build-up or foreign particles in the supply.
The adjustable maximum temperature stop prevents accidental scalding caused by overadjustment of the handle.
Many Series 410 valves and shower systems can be selected to meet the Americans with Disabilities Act (ADA) [see
back page for details].

APPLICATION
The Series 410 Hydroguard is particularly recommended in
showers and shower bath installations for motels, hotels,
dormitories, and high rise apartment buildings.
OPERATION (SEE FIGURE 1)
Hot and cold water enter their respective ports and the pressures are equalized through the action of the balance poppet
(1). The entire balancing poppet assembly is contained in a
Celcon chamber (2). This chamber is replaceable as a complete cartridge. After the hot and cold pressures are equalized, they are mixed by the action of a mixing plate (3). 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 maximum temperature stop (4) allows the user to set the
maximum 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
maximum temperature setting.
NOTE: Following any maintenance of unit, maximum
temperature stop must be reset. See page 5 for instructions.

MAINTENANCE
Troubleshooting
What to look for:
1. 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).
2. 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.
3. Flow is untempered hot or cold water.
a. The water supplies are connected to the wrong ports.
b. Diaphragm is ruptured; replace with new cartridge.
c. Check for foreign material that may be clogging the
cartridge.
4. Flow of water continues when Hydroguard is shut off.
a. Worn shut-off discs. Replace worn disc.
b. Scratched mixing plate.
c. Erosion. Contact a Powers applications engineer to
order replacement parts.
5. 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. See page 5 to set the
maximum temperature limit stop.
c. Hot water temperature is too low.
6. Standard inlets are desired.
See Figure 2 for instructions on standard inlets (with cold
water entering the COLD port). With mixer in closed position, the notch
in the top spline on the stem must FACE
the outlet.
7. Reversed inlets are desired.
See Figure 3 for instructions on reversing the mixing plate
(with cold water entering HOT port). For reversed inlets,
the notch
must face AWAY FROM the outlet port.
Note: When using reversed inlets, the HOT and COLD
inlets should be identified to avoid confusion during
future maintenance.

SERVICING
1. Shut off upstream water supply.
2. Remove the dial assembly and handle. See page 3 for relationship of parts. Unscrew four cap screws and remove
cap assembly by gently pulling on stem.
3. TO REMOVE THE BALANCE CHAMBER, using a balance
chamber extraction tool (Part No. 401-202) is highly recommended. To use the extraction tool, follow instructions
below:
a. Insert hooked ends of extraction tool into HOT and
COLD outlet ports of the balance chamber (see Figure
4).
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.
4. Replace necessary items and reassemble. A small amount
of silicone gel on the cartridge, O-rings, and related surfaces will aid in the assembly.
CAUTION: Do not pinch cartridge O-rings during assembly.
5. Replace bonnet with new bonnet gasket. Proceed to step 6
to reset maximum temperature setting.
MAXIMUM TEMPERATURE SETTING
6. MAXIMUM TEMPERATURE SETTING (refer to Figure 5).
This must be set on the job and following any maintenance
or servicing to the valve. Mixer is factory set to pass full
HOT water.
a. Loosen adjustment stop screw (do not remove).
Gradually rotate stem counterclockwise to get desired
maximum water temperature. (Maximum Temperature
Stop will rotate along 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.
