Key
Control or Indicator
Function or Use
1
Control Box Assembly
Indicator lamps; switches to start, operate and stop (including
through 44).
2
Panel Light
Provides light for inside of the ROWPU and for the control panel.
It is mounted on a moveable bracket that can be pulled forward to
provide more light on the control panel.
3
In-Line TDS Monitor
Used to continually monitor quality of product water (see figure
4
Vent Cartridge Filter Valve
Relieves air from cartridge filter.
5
Vent Pulse Dampener Valve
Relieves air from pulse dampener.
6
Vent Multimedia Filter Valve
7
Backwash Valve
Backwash valve has two positions: NORMAL and BACKWASH.
In NORMAL, the valve closes the backwash inlet and allows raw
water to flow through the ROWPU. In BACKWASH, the raw
water inlet is closed and water is allowed to flow through the
backwash inlet. After backwashing, the valve should be returned
to the NORMAL position.
8
Multimedia Filter Gage
Indicates differential pressure across the multimedia filter.
9
Waste Outlet
10
R.O. Vessels Gage
Indicates differential pressure across the R.O. vessels.
11
Raw Water Flow
Measures in gallons per minute the amount of water drawn in by
raw water pumps and fed into ROWPU.
12
Backwash Water Inlet
Connection for backwash hose.
13
Raw Water Inlet
Connection for hose from raw water pumps
14
Ground Rod
Used to ground ROWPU. Protects personnel from electrical
shock.
15
Backwash Water Flow Gage
Measures amount of water flowing through multimedia filter dur-
ing backwash cycle.
16
R.O. Pressure P.S.I. Gage
Shows discharge pressure of the R.O. pump in pounds per square
inch (psi). Gauge reading depends on setting of REGULATE
PRODUCT FLOW valve.
17
Brine Flow Meter
Measures amount of brine flow from the ROWPU in gallons per
minute (gpm).
18
Regulate Product Flow Valve
Closes the brine outlet of the R.O. vessels. Controls product water
flow rate. Regulates output pressure of the R.O. pump.
