(See Figure 1)
A On / Off Switch – Turns the unit on and off.
B Product Pressure Switch – Automatically turns
the unit on and off based on the product water
pressure.
C Reject Control Valve - Controls the amount of
reject flow.
D Reject Recycle Control Valve – Controls the
amount of recycle flow.
E Prefilter Pressure Gauges - Indicate the inlet and
outlet pressures of the prefilter. The difference
between these two gauges is the prefilter
differential pressure.
F Pump Discharge Pressure Gauge - Indicates the
membrane feed pressure.
G Reject Flow Meter - Indicates the reject flow rate
in gallons per minute (gpm).
H Product Flow Meter - Indicates the product flow
rate in gallons per minute (gpm).
I Prefilter Housing - Contains the RO prefilter.
J Automatic Inlet Valve - Opens when pump is on
and closes when the pump is off.
K RO Feed Pump - Pressurizes the RO feed water.
L RO Membrane Vessel(s) - Contains the RO
