The Powers Hydropanel II Series 450-4200 Shower System com-
bines thermostatic water control with the convenience of modu-
lar 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-actu-
ated thermostatic motor to quickly sense any change in hot or
cold supply water temperature or pressure and respond to main-
tain the user-selected temperature. In the event of cold water fail-
ure, 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 450-
4200 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

TECHNICAL INSTRUCTIONS
HYDROPANEL
TM
II SHOWER SYSTEM
with Hydroguard 420 Thermostatic Valve
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].
