(to shut-off system at tank full) Pretreatment Notations: (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. -

Page 9: System Installation
AA System Operation Manual 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"... - Page 10 AA System Operation Manual 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.

Page 11: Initial System Start-Up
AA System Operation Manual INITIAL SYSTEM START-UP SYSTEM FLUSH: Direct permeate discharge to drain for first 30 minutes of operation. 1. Connect the system to the appropriate electrical outlet, 110vac or 220vac 1 phase. The solenoid will open as soon the power is applied and the unit will come on if the feed pressure is high enough. -
Page 12: Shutdown
AA System Operation Manual SHUTDOWN Cut off feed water supply and/or unplug unit. If the unit is to be shut down for more than 1 week, a membrane preservative should be used (AMI Model No. AM-88). The preservative can be injected into the system by using a tank and recirculation pump. -

AA System Operation Manual ADJUSTMENT OF PRESSURE SWITCHES Tools Required: Flat Blade Screw Driver CAUTION: 115 VOLT SHOCK HAZARD Turn off R.O. unit and disconnect all electrical power prior to removing cover plates on pressure switches. LOW & HIGH PRESSURE CUT-OUT SWITCH Loosen nut and remove cover plate. -
Page 14: Maintenance Tips
AA System Operation Manual MAINTENANCE TIPS MAINTAIN PROPER OPERATING CONDITIONS Do not exceed 200psi on the pressure gauge. Do not over use recycle flow. This can cause premature scaling of the membrane. A proper concentrate flow is required for a long membrane life. Test the water from your carbon filter once a week for chlorine break through. - Page 15 AA System Operation Manual WHEN TO CLEAN MEMBRANES In normal operation, the membrane in reverse osmosis elements can become fouled by mineral scale, biological matter, and grime. These deposits build up during operation until they cause loss in water output or loss of salt rejection, or both. Elements should be cleaned whenever the water output rate drops by 10 percent from its initial flow rate (the flow rate established during the first 24 to 48 hours of operation) or when salt content in the product water rises noticeably.

AA System Operation Manual C-C2510-A11 Acidic Cleaning Cartridges for TF Type Membranes User Instructions Caution: Handle cartridges carefully. Cleaning Procedure: 1. Shut down to RO system. 2. Disconnect permeate line and divert to drain before any cleaning cartridge is installed. 3. - Page 18 AA System Operation Manual C-C2510A22, C-C2520A22 Alkaline Cleaning Cartridges for TF Type Membranes User Instructions Caution: Handle cartridges carefully. Cleaning Procedure: 1. Shut down the RO system. 2. Disconnect the permeate line and divert permeate to drain during cleaning. 3. Remove the pre-filter cartridge from the filter housing.
- Page 19 AA System Operation Manual STORAGE PROTECTION To prevent bacterial growth and help maintain flux, it is recommended that elements be immersed in AM-88 if the system will be off for more than 3 days.

AA System Operation Manual REPLACING PREFILTERS PROCEDURES Shut unit down. Close inlet supply valve. Turn the blue pressure housings counterclockwise (use filter wrench AMI Model No. H-C9200 for standard 10” filter housing). Filter cartridge should come free from the housing top and remain in the housing. Remove and replace cartridge. -
Page 22: Temperature Correction
AA System Operation Manual Temperature of the feed water and the net driving pressure across the element must be taken into account before comparing or evaluating the performance of a membrane element or a reverse osmosis system. Temperature Correction Factor The water temperature is one of the key factors in the performance of the reverse osmosis membrane element. -
