Powers 450 Meter HydroPanel II Shower System with Metering Valve - Manual

The Powers Hydropanel II Series 450-4000M Shower System
combines the water control of metering valves with the conve-
nience 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 one-
year 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.

DESCRIPTION
A master mixer supplies tempered water to the metering valve.
The metering valve consists of a cast bronze body and pushbut-
ton around a timing cartridge. Inside the cartridge is a timing nee-
dle and sealed chamber of silicone fluid. Attached around the
end of the cartridge is a plastic valve seat. By pressing the push-
button, a bather forces open the valve seat to pass water to the
showerhead.
The pushbutton action also forces the silicone inside the car-
tridge 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 run-
time 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.
