HydroPanel™ II Shower System

with HydroGuard® e420 Combination Valve

Technical Instructions

Description n

The Powers HydroPanel™ II Shower System with HydroGuard® e420 valve combines
thermostatic and pressure balancing water control with the convenience of modular
shrouding. It provides a concealed shower system where in-wall piping does not exist
or may not be practical. The HydroGuard® e420 features heavy cast brass construction,
self actuated thermostatic element 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 element virtually shuts off the flow of
hot water. A built-in adjustable metal-to-metal temperature limit stop reduces chances
of accidental scalding due to over adjustment of handle. HydroPanel™ II comes complete
with inline checkstops, stainless steel shrouding, e420 combination valve, ADA compliant
lever handle, piping, end caps and mounting hardware. Some models feature a stainless
steel soap dish. An optional hand shower comes preassembled.

WARNING

FAILURE TO COMPLY WITH PROPER INSTALLATION AND
MAINTENANCE INSTRUCTIONS COULD CONTRIBUTE
TO THE VALVE FAILURE, RESULTING IN INJURY AND/OR
DEATH.

TO ENSURE THE ACCURATE AND RELIABLE OPERATION
OF THIS PRODUCT, IT IS ESSENTIAL TO:

• Properly design the system to minimize pressure and tempera­ture variations.

• Conduct an annual maintenance program to ensure proper
operation of all critical components.

• Check outlet temperature to ensure it does not exceed
110°F (43°C). Make sure temperature limit stop is properly re­set to maximum 110°F (43°C) following valve maintenance or
repair. Tampering with limit stop in any way may result in scald­ing temperature causing serious bodily harm

!

WARNING

Need for Periodic Inspection: Periodic inspection by a
licensed contractor is recommended. Corrosive water condi­tions, and/or unauthorized adjustments or repair could render
the valve ineffective for service intended. Regular checking
and cleaning of the valve’s internal components and check
stops helps assure maximum life and proper product func­tion. Frequency of cleaning and inspection depends upon
local water conditions.

Installation should be in accordance with acceptable plumbing
practices. Flush all piping thoroughly before installation.

Failure to do so can result in valve malfunction. Before installation
of HydroPanel™ II, rotate the stem or handle off.

Position The HydroPanel™ II Unit n

1. See Figure 1, 2 & 3 to 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 centerlines of the two units is
36 inches (914 mm).

2. Determine floor to showerhead height for the unit.
Recommended heights--for men 77" (1956 mm), male youth 66"
(1676 mm), women 70" (1778 mm) and female youth 60" (1524
mm).

3. The preassembled copper tubing for supply water inlets are
4-3/4" (120 mm) from the top of the shroud and 2-11/16" (68 mm)
left and right of the centerline. Adjust supply line accordingly.

Install the Piping Assembly n

1. Detach the piping from the shrouding by removing screw A
above the showerhead (see Figure 4). Slide piping out of the
shrouding; the showerhead remains attached to the shroud.

2. For mounting the piping assembly bracket B, use bracket as
a template and drill 2 small holes in the wall at showerhead
height.

3. For mounting lower piping assembly, drill a small hole in the
wall that is 20-1/2" (520 mm) below the upper bracket (B) and
1-13/32" (36 mm) to the left and right of the center line.

4. Install mounting anchors per room specifications. Secure
bracket with mounting screws (NOT INCLUDED).

5. Connect the supply lines to the piping assembly.

Attach the Shrouding n

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.

1. To remove scored section, hit it sharply with a hammer.

2. To connect the showerhead, slide the showerhead nipple
on the inside of the shroud into the piping assembly. Secure
shrouding with the screw at A.

3. Fit the handle over the stem. Turn on water supply. Turn
handle fully counterclockwise and measure the outlet water
temperature. Adjust temperature if required (see high tem­perature limit stop adjustment)

4. Check for leaks. Secure shrouding.

5. The cover plate fits over the tabs around the shroud valve
hole. Snap the cover plate into place. Secure it at D and D'
with screws.

6. Place the name plate over the cover plate, snap the retaining
ring. Thread sleeve on the bonnet making sure that the cut-a­way on the sleeve is toward you, and it is in the bottom posi­tion when tightened.

7. Install the handle with the screw provided.
