Powers 450-e420 User Manual
The Powers Hydropanel II Series 450-4200 Shower System combines thermostatic 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 420 valve uses a self-actuated thermostatic motor to quickly sense any change in hot or
cold supply water temperature or pressure and respond to maintain the user-selected temperature. In the event of cold water failure, the thermostatic motor virtually shuts off the flow of hot
water. The unit also features a concealed handle rotation stop to
guard against over adjustment of the handle.
The Series 450-4200 Hydropanel II comes complete with the
stainless steel Hydropanel II Shrouding, Series 420 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 Hydroguard 420 valve is CSA approved, and the Series 4504200 Hydropanel II carries a one-year limited warranty.
The following instructions serve as guide for installation, general
maintenance and parts replacement for the Hydropanel II Series
450-4200. For detailed repair and maintenance instructions for
the Hydroguard 420 valve, please refer to Form #TI420-1. For
repair and maintenance of checkstops, see Form #129-028. For
specification or installation of the Hydropanel II Optional Modular
Shrouding for shower rooms, please refer to Forms #PS450SH or
#TI450SH.
TECHNICAL INSTRUCTIONS
HYDROPANELTMII SHOWER SYSTEM
with Hydroguard 420 Thermostatic Valve
A Watts Industries Co.
DESCRIPTION
Hot and cold water enter respective ports in the valve and mix in
a chamber containing a thermostatic motor. This liquid filled
motor connects to the valve assembly, which includes a hot
water seat and a shut off disc. With the adjustment handle in full
clockwise (OFF) position, the shut-off disk closes the mixing
chamber from the outlet, and the hot water disc seats to prevent
crossflow.
Rotating the adjustment handle repositions the valve assembly to
mix hot and cold supply water in proportions required to produce
the user-selected temperature. The mixed water passes over the
shut-off disc, to the showerhead. If the mixed water temperature
differs from the handle setting (i.e., the hot or cold supply water
temperature or pressure changes) the liquid filled bellows inside
the thermostatic motor will contract or expand. This movement
repositions the valve assembly to maintain the desired delivery
temperature.
A handle rotation stop limits the movement of the control handle
toward the full hot position. The Hydroguard 420 valve is factory
set to deliver tempered water up to 115°F [46.1°C] with equal
supply pressures, hot water temperature 140°F [60°C], cold water
temperature 60°F [15.6°C].

Before installation of any Hydropanel II unit, rotate the stem (or
handle if attached) 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 centerline. 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 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
#450-4204 and #450-4205 Hydropanel II units, the hand-shower,
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
the 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] to the 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.
