The Powers Hydropanel II Shower System with Hydroguard 410
Valve combines pressure balanced water control with the convenience of modular shrouding. Hydropanel II stainless steel
shrouding provides a concealed shower system where in-wall
piping does not exist or may not be practical. The Hydroguard
410 valve uses a proven poppet/diaphragm cartridge to balance
hot and cold water supply pressures and deliver water to the
shower at a user-selected temperature. The Celcon® balancing
cartridge and poppets, and wide seat clearance in the valve provide maximum protection against lime and dirt build up. The
valve opens in the cold position and features a handle rotation
stop to guard against over adjustment of the handle.
The Series 450-0410 Hydropanel II comes complete with the
stainless steel Hydropanel II Shrouding, Series 410 Hydroguard,
in-line checkstops, piping, showerhead, end cap and mounting
hardware. Some models feature a stainless steel soapdish. Some
models feature an ADA compliant lever handle. An optional
handshower comes preassembled with a full spray pushbutton
handshower, 60” hose, 18” mounted glide-bar and connectors.
The Series 450-0410 Hydropanel II units carries a one-year limited warranty.

TECHNICAL INSTRUCTIONS
HYDROPANELTMII SHOWER SYSTEM
with Hydroguard 410 Pressure Balancing Valve
DESCRIPTION
Hot and cold water enter respective chambers in the valve. A
diaphragm/poppet assembly floats between these chambers and
balances the supply water pressures. The Celcon chamber/balancing assembly is replaceable as a complete cartridge. Any
change in supply pressure moves the diaphragm/poppet assembly to equalize the supply water ratios and minimize the shower
temperature disturbance.
A Celcon mixing plate separates the balancing chambers from
the mixing chamber. When the adjustment handle is in its full
clockwise position (OFF), the mixing plate closes both supply
chambers. As the valve handle rotates toward the stop, hot and
cold supply water pass through slots in the mixing plate in proportions required to produce the user selected temperature.
Tempered water exits the valve and passes to the showerhead.
A handle rotation stop limits the movement of the control handle
toward the full hot position. The Hydroguard 410 does not compensate for supply water temperature changes, so any variation
in the supply temperatures will affect the control point temperature.

Before installation of any Hydropanel II unit, rotate the stem (or
handle) of the valve to its full clockwise position (OFF).
POSITION THE HYDROPANEL II UNIT
(See Figures 1 and 2) Determine the horizontal position of the unit
according to shower room layout, and mark the centerlines. For
multiple shower applications, the recommended minimum distance between the centerline of two units is 36 inches [914mm].
1. Determine the floor-to-showerhead height for the unit.
Recommended heights are listed below:
Men - 77” [1956mm] Youth - 66” [1676mm]
Women - 70” [1778mm] Youth - 60” [1524mm]
2. The preassembled copper tubing for supply water inlets are
6-5/8” [168mm] from the top of the shroud, and 2-11/16”
[68mm] left and right of the centerline. Adjust supply piping
accordingly.
Install the Piping Assembly
The piping and Hydropanel II shrouding must be separated
before mounting to wall. The valve trim and cover plate are in a
separate plastic bag in the Hydropanel II shipping carton. For
#450-0414 and #450-0415 Hydropanel II units, the handshower,
hose and showerhead base come preassembled to the shrouding. Refer to Figure 4.
3. Detach the piping from the shrouding, by removing screw A
above the showerhead. Slide piping out of the shrouding;
the shower head remains attached to the shroud.
4. For mounting the piping assembly upper bracket B, use
bracket as a template and drill two small holes in the wall at
showerhead height.
5. For mounting the piping assembly lower bracket C, drill two
small holes in the wall that are 18-3/4” [476mm] below the
upper bracket and 11/16” [17mm] left and right of centerline.
6. Install any mounting anchors as detailed by the individual
room specifications.
7. Secure upper piping bracket B with mounting screws (not
included).
8. Secure lower piping bracket C with mounting screws (not
included).
9. Connect the supply lines to the piping assembly.
Attach the Shrouding
Do Not remove the entire chrome plated end cap from the
shrouding; it functions as an end cap and gasket for shroud
extension. Part of the end cap can be broken out to provide vertical and horizontal piping clearance.
10.To remove scored section, hit it sharply with a hammer.
11.To connect the showerhead on the shroud to the water outlet pipe, slide the showerhead nipple on the inside of the
shroud into the piping assembly. The End Cap will slide over
the supply piping. Secure the shrouding with the screw at A.
Test the System
Before final assembly, test the Hydropanel II system.
12. Fit the handle onto the valve stem and turn clockwise to the
shut off position.
13.Turn on water supply, and then rotate the valve handle counterclockwise. Water should come through the showerhead.
14.Now turn handle fully counterclockwise and measure the
temperature of the outlet water. Wait until the temperature
stabilizes for an accurate reading.
15.Turn off valve (fully clockwise) and check all connections
(showerhead, pipe connections, valve bonnet) for leaks.

Set the Handle Rotation Stop
The Hydroguard 410 is a pressure balancing valve, and therefore
cannot compensate for variations in hot water supply temperatures. It is factory set to pass full hot water.
The handle rotation setting must be adjusted to limit the distance
the user can rotate the handle towards the full hot water position.
CAUTION: Any repair or modification of the valve will affect the
high temperature setting. Any changes in inlet water temperature
will require readjustment of the handle rotation stop.
When the user rotates the handle fully counterclockwise, the limit
stop will rest against the bonnet stop.Refer to Figure 5.
16.Remove the valve handle. Slide the limit stop retaining Oring up, but do not remove.
17.If the measured temperature exceeds the desired maximum
outlet temperature, move the limit stop ONE SPLINE COUNTERCLOCKWISE. This will DECREASE the handle rotation
and the maximum adjustable temperature.
18.If the measured temperature is below the desired maximum
outlet temperature for the system, move the limit stop ONE
SPLINE CLOCKWISE. This will INCREASE the handle rotation and the maximum adjustable temperature.
19.For fine temperature adjustments, use the limit screw.
20.Turn the screw CLOCKWISE to further DECREASE the maximum adjustable temperature.
Turn the screw COUNTERCLOCKWISE to further INCREASE
the maximumm adjustable temperature.
21.Slide the limit stop O-ring back into place, and replace handle. Repeat steps 12 through 20 until desired maximum outlet temperature is reached. Remove handle before final
assembly of shrouding.
Assemble the Valve Cover and Handle
The Hydropanel II piping assembly and shrouding must be
securely mounted to the wall before the valve cover plate and
handle assembly are attached.
NOTE: Only properly mounted piping and shrouding provide the
stable platform needed for the cover plate to snap snugly into
place.
The valve parts and cover plate are packaged in a separate plastic bag in the Hydropanel II shipping carton.
22.The cover plate fits over the tabs around the shroud valve
hole. Snap the cover plate into place.
23.(Figure 4) Secure the cover plate to the shroud and the piping assembly at D and D’, with the 1-1/2” stainless steel
screws.
24.(Figure 6) Place the graphic insert into the cover plate, slide
the brass sleeve over the stem and fit the rubber retainer
inside the edge of the cover plate hole.
25.(Figure 6) Place the tri-handle over the stem, and secure with
retaining washer and screw using the 3/32” wrench (included). Snap the button plug into place.
26.(Figure 4) Finish assembly by tightening the shrouding screw
at A above the showerhead.
Before servicing checkstops or piping, turn off the supply water
upstream. To access the checkstops, remove the valve handle
assembly, cover plate and shrouding (refer to Install the Piping
Assembly).
At least every twelve months, open up the checkstops and check
for free movement of the poppet.
Before servicing the valve, either turn off the water supply
upstream (the shroud does not have to be removed), OR access
and close the checkstops. To close the checkstops, turn the
adjustment screw on each fully clockwise.
Every six months, check and adjust the handle rotation setting.
Every twelve months, remove the valve bonnet and check the
internal components for freedom of movement.
To service or clean the showerhead, unscrew from shroud at hex
nut. Service as necessary, and reattach.
