II SHOWER SYSTEM with Metering Valve
DESCRIPTION
The Powers Hydropanel II Series 450-4000M Shower System combines the water control of metering valves 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. Behind the shroud, a mechanical metering valve delivers pre-tempered water to a showerhead. With the push of a button, the metering valve opens to allow water flow for a preset time (adjustable to 60 seconds), then automatically closes. Tempered water can be supplied upstream by a master mixing valve like the Powers Hydroguard
430 Thermostatic Mixing Valve or Hi-Lo Supply Fixture, with or without a cabinet.
The Series 450-4000M Hydropanel II comes complete with the stainless steel Hydropanel II Shrouding, mechanical metering valve with stop, piping, showerhead, end cap and mounting hardware. Some models feature a stainless steel soapdish. An optional handshower comes preassembled with a full spray pushbutton handshower, 60” hose, 24” mounted glide-bar and connectors. Series 450-4000M Hydropanel II units carry a oneyear limited warranty.
The following instructions serve as guide for installation, general maintenance and parts replacement for the Hydropanel II Series
450-4000M Shower System. For specification or installation of the Hydropanel II Optional Modular Shrouding for shower rooms, please refer to Forms #PS450SH and #TI450SH.

OPERATION
A master mixer supplies tempered water to the metering valve.
The metering valve consists of a cast bronze body and pushbutton around a timing cartridge. Inside the cartridge is a timing needle and sealed chamber of silicone fluid. Attached around the end of the cartridge is a plastic valve seat. By pressing the pushbutton, a bather forces open the valve seat to pass water to the showerhead.
The pushbutton action also forces the silicone inside the cartridge to flow across a piston check valve. As the silicone slowly meters back, the cartridge returns to its original state, and the valve seastto stop the water flow. The distance between the valve seat and timing needle determines the metering cycle
(shower run time). Turning the needle in or out adjusts the runtime from a few seconds up to one minute.
The entire timing mechanism remains separate from the water, which makes the valve more reliable and less prone to “sticking.”
The button can be pushed at any time to restart the timer.

INSTALLATION
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 [1914mm].
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 supply water inlet is 8-3/4”
[222mm] from the top of the shroud, and 1-1/2” [38mm] to the right of the centerline. Connect supply piping accordingly.

Install the Piping Assembly
The valve handle assembly, piping and Hydropanel II shrouding must be separated before mounting to wall. For #450-4004M and
#450-4005M Hydropanel II units, the handshower, hose and showerhead base come preassembled to the shrouding. Refer to
Figure 4.
3. Remove the screws holding the faceplate to the shroud at D.
Slide the faceplate off over the valve cover.
4. Remove the two screws at E that secure the shroud to the valve.
5. Detach the piping from the shrouding, by removing the screw at A above the showerhead. Slide the piping out of the shrouding; the showerhead remains attached to the shroud.
6. For mounting the piping assembly upper bracket (B) , use the bracket as a template and drill two small holes in the wall at showerhead height.
7. For mounting the piping assembly lower bracket (C), use the bracket as a template to mark mounting position, and drill 3 holes.
8. Install any mounting anchors as detailed by the individual room specifications.
Figure 4.
Figure 3: Front dimensions,
Hydropanel II Series
450-4004M.
9. Secure upper piping bracket B with mounting screws (not included).
10.Secure lower piping bracket C with mounting screws (not included).
11.Connect the supply line 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 the 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. Turn on water supply and push the metering valve button. Water should come through the showerhead for the desired time.
When valve meters off, check all connections (showerhead, pipe connections, valve) for leaks.

INSTALLATION, CONTINUED
Set the Metering Cycle
The metering valve can cycle for up to one minute.
12.To adjust, insert the the 3/32” allen wrench into the small hole in the center of the pushbutton (see Figure 5). Inside the hole is the metering cycle timing needle.
13.To increase the shower time, turn the allen wrench counterclockwise. This will widen the distance inside the valve between the timing needle and the valve seat.
14.To decrease the shower time, turn the allen wrench clockwise. This will shorten the distance inside the valve between the timing needle and the valve seat.
Assemble the Valve Cover
15.(Figure 4) Secure the piping to the shroud with the two screws at E.
16.(Figure 4) Slide faceplate over the valve and attach it to the shroud with the 1” screws at D.
17.(Figure 4) Finish assembly by tightening the shrouding screw at A above the showerhead.
SERVICING THE HYDROPANEL UNIT
Before servicing valve or piping, turn off the supply water upstream or close the stop valve.
To access the stop valve, refer to Figure 5. Remove the two faceplate screws, then slide the faceplate over the valve. A small hole in the shrouding allows access to the stop valve. To close, turn the adjustment screw fully clockwise. To open, turn the adjustment screw fully counterclockwise.
TROUBLESHOOTING
*NOTE*: If problems with water tempering occur, please refer to the appropriate technical instructions for your master mixing valve.
1. If the flow of water is less than desired...
a. The upstream master mixer may not be fully open.* c. The showerhead may be clogged. Remove and clean.
b. The metering cartridge may be sticking. Access and check.
Service with Repair Kit #141 839.
d. The stop valve may not be fully open. Access and adjust accordingly.
2. If the flow of water is completely shut off...
a. The upstream master mixer may be shut-off.* b. The metering valve may be stuck. Access and check.
Service with Repair Kit #141 839.
c. The stop valve may be closed. Access and open by turning the adjustment screw fully counterclockwise.

Timing Adjustment
- longer shower time - shorter shower time
Figure 5.
The timing cartridge for the metering valve is replaceable as a single cartridge. Every six months, check the timing on the valve and inspect for sticking.
To service or clean the showerhead, unscrew from shroud at hex nut. Service as necessary, and reattach.
3. If water continues to flow from the showerhead after valve shut-off...
a. The metering valve may damaged. Access and check for sticking. Service with Repair Kit #141 839.
4. If water continues to flow beyond desired cycle time...
a. The metering valve timing needle needs to be readjusted.
Refer to Setting the Metering Cycle.
