Powers 450 Meter HydroPanel II Shower System with Metering Valve - Manual (Page 3)

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 counter-
clockwise. 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 clock-
wise. 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.
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.
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.
