GENERAL INFORMATION and SAFTEY
READ THIS MANUAL: Prior to operating or servicing this unit, this manual must be read
and understood. If anything is not clear, call for assistance before proceeding. Keep this and
other associated manuals for future reference and for new operators or qualified service
personnel.
USE PROPER POWER CONNECTIONS: Use proper wiring and connection methods to
satisfy local electrical codes.
SHOCK HAZARD: Connect this unit to a properly grounded connection in accordance with
the National Electrical Code. DO NOT, under any circumstances, remove the ground wire or
ground prong from any power plug. Do not use extension cords or an adapter without proper
consideration.
WARNING: Unplug the system prior to servicing.
WARNING: Do not make any alteration or modification in the wiring or plumbing of the
system. This can result in damage to the system and cause injury to operators or users.
WARNING: Flush the system for 30 minutes before use to remove all chemicals present.
CAUTION: Chlorine can damage the membrane. Chlorine should be removed from the feed
stream before entering the system. The feed stream should be tested for chlorine at least
once a week. Always follow proper maintenance procedures.
CAUTION: Never let the system freeze. Freezing can damage the membrane and plumbing.

NOTES:
1. All systems rated at 77 Degrees Fahrenheit (25 Degrees Celsius) using 1000 ppm sodium
chloride (NaCl) solution. System capacity decreases significantly with decrease in feed
water temperature (see temperature correction chart).
2. Chlorine requirements for the feed water are as follows:
Thin-Film (standard) 0 ppm
CA (special order only) 0.1 ppm Minimum
3. Feed water must be filtered to a turbidity of less than 1 NTU.
4. System recovery (permeate to concentrate ratio) must be maintained at the recommended
level. A higher than recommended recovery will lead to a premature fouling of the
membrane with a loss of permeate flow and permeate quality.
5. Softened water should be used for the feed water to the RO system.

(Additional pretreatment equipment is available from Applied Membranes, Inc.)
* Softened feed water is recommended.
** Depends on the turbidity of the feed water. For water with high turbidity an additional back-
washable multi-media system may be required to help to minimize cartridge replacements.
*** An additional back-washable pre-carbon system may be required to help to minimize cartridge
replacements.

COMPONENT IDENTIFICATION
AA System Component Diagram
# Item Description
1. Solenoid Valve Normally closed. Opens when there is sufficient feed pressure
2. Cartridge Filter 5 micron sediment filter.
3. Carbon Filter Extruded carbon cartridge to remove chlorine from the feed stream.
4. Low Pressure Switch Shuts the system down if the inlet pressure is lower than 12 psi
(adjustable).
5. High Pressure Pump Rotary Vane pump to pressurize the incoming water to 150-200 psi.
6. Membrane Modules Membrane elements housed in stainless steel pressure tubes.
Membranes require proper flow and pressure for good operation.
7. System Pressure Gauge Measures the pressure at the exit end of the membrane modules.
8. Control Valve To adjust system pressure. Must not be completely closed when
the system is in operation.
9. Tank Pressure Switch Turns system on/off based on pressurized storage tank level.
10. Carbon Filter Extruded carbon cartridge to remove taste and odor from the
permeate stream.
11. TDS Monitor (optional) Monitors the permeate quality.

REVERSE OSMOSIS SYSTEM INSTALLATION
1. Locate R.O. system with adequate clearance from walls and other equipment to enable
membrane servicing.
2. Run four polyvinyl tube lines to the system as follows:
Line #1: Bring raw water supply feed to the inlet of the first prefilter housing. The line
size should be 3/8" . Install a valve in this line. The valve opening should not
restrict the water flow.
CAUTION: Pump and system performance will be adversely affected if the
suction line is restricted.
Line #2: Run a 1/4" line from the open end of the control valve to a drain. Insure that no
liquids from other lines in the plant flow back through this line.

Line #3: Run a 3/8" line from the permeate outlet located at right end of PVC manifold to
a pressurized storage tank.
Line #4: Run a 3/8" line from the permeate outlet of the post-filter housing to a faucet or
other final permeate destination.
CAUTION: Be sure that all lines are connected before plugging in unit power.
