NOTES:
1. All systems rated at 50°F (10°C) using 1000 ppm sodium chloride (NaCl) solution. System capacity decreased signifi cantly with decrease in feed water temperature.
2. Chlorine requirements for the feed water are: a. Thin-Film (standard) 0 ppm
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.

INSTALLATION
1. Locate RO system with adequate clearance from walls and other
equipment to enable membrane servicing.
2. Run five polyvinyl tube lines to the system as follows:
LINE 1
Connect raw water feed supply to the solenoid valve inlet in front of the fi rst cartridge fi lter housing. This will require ½ inch threaded pipe fi tting and adaptor for the feed line. If desired, install an isolation valve in this line; ensure the valve opening does not restrict the water fl ow.
LINE 2
Run a ⅜ inch line from the open end of the concentrate valve to a drain. Ensure that no liquids from other lines near this drain fl ow back through this line.
LINE 3
Run a ⅜ inch line from one of the two permeate outlets on the back of the system to the pressurized permeate storage container.
NOTE: The recirc fl ow line is pre-connected at the factory.
LINE 4
Run a ⅜ inch line from the other permeate outlet to the humidifi er or end process being fed by the system.
FIGURE 5-1: SOLENOID VALVE INLET
CAUTION
LINE 5
Run a ¼inch line from the pressurized relief solenoid to a drain. Ensure that no liquids from other lines near this drain fl ow back through this line.
Pump and system performance will be adversely affected if the feed/suction line is restricted.

PRE-TREATMENT CONNECTION
If you have pre-treatment equipment and you wish to shut-down the RO system during backwash or regeneration, a microswitch is required (standard with DriSteem water softeners).
1. Wire the microswitch to terminal labeled PreTreat inside controller.
When the equipment goes into backwash or regeneration, the pre-treat limit switch opens and turns the power off the inlet solenoid valve, which then turns the RO pump off (and back on) when the cycle is complete.
CAUTION
The controller is rated for maximum 20 amp total load. Terminal strip P11 is dry contact for input signals from tank full, pressure fault and pretreat lockout. Use a small gauge 2 conductor cable for these wire connections.

RO PUMP WIRING
The RO pump connects to P4 (L1) and P5 (L2) RO pump terminals. This output can operate 110/240 VAC motors up to 1HP directly.
INLET WIRING
The inlet solenoid valve connects to P6 (L1) and P7 (L2) inlet terminals.
PRESSURE FAULT SWITCH
The feed pressure switch is connected to the pressure fault input. Low pressure (factory preset 8 psi) will shut system off.
PRETREAT SWITCH
In systems with pretreatment, a pretreat lockout switch can be connected to the pretreat input. This switch should operate when the pretreatment device is out of service.
NOTE: The output from the pretreatment device must be a dry contact and must not supply voltage.
TANK FULL SWITCH
DriSteem systems use a pressure switch to keep the pressurized storage tank between 30-50 psi (207-345 kPa). The switch is connected to the tank full input.

System operation
OPERATION
The unit has a single mode of operation ON with six sub-modes or states as indicated by the steady or fl ashing panel lights. Any light condition other than steady power ON indicates the unit is effectively in standby-mode. If there are no lights, the system is OFF and all outputs are turned off. In the operating mode, the unit operates automatically. All inputs are monitored and the outputs are controlled accordingly. Pressing the power key will toggle the unit from off to operate or from operate to off. If power is removed from the unit when power is reapplied, the unit will restart in the mode it was in when the power was removed.
When the power switch is turned ON, the center status LED will light green, the valve will open, and the RO pump will start.
Under normal operation the RO unit will run until:
a. the storage tank is full (right LED amber) or b. pretreat lockout has occurred (center status LED fl ashing green).
When a or b has cleared after a time delay, the RO unit will restart and the center status LED will return to green. Switch setting three selects a two second or 15 minute tank full restart time delay.
Upon an alarm signal for pressure fault, the left status LED will fl ash red, the RO pump will stop, and the inlet valve will close and the RO pump will turn OFF.
• If switch one and two are in the OFF position (disabled), the left status LED
will be a steady red and the RO will not restart until the power switch has been manually cycled OFF then ON to reset the unit.
• If switch one is in the ON position (auto reset), every 60 minutes the RO
will start and stop again if a pressure fault continues.
• If switch two is in the ON position (pressure fault retry), the RO will attempt
to restart after 30 seconds, then fi ve minutes, then 30 minutes. If the pressure alarm has not cleared after the third try, the RO unit will remain OFF until manually reset.

OPERATION
System operation continued
INITIAL SYSTEM START-UP
SYSTEM FLUSH
Direct permeate discharge to drain for fi rst 30 minutes of operation.
1. Connect the system to the appropriate electrical outlet, 110-120 VAC or 208-240 VAC 1 phase.
2. Ensure all plumbing connections are open to allow flow. Open the concentrate valve (counterclockwise). Close the recirc valve (clockwise).
Ensure suffi cient pressure (40 psi recommended) is in feed line. If pressure is less than 8 psi, the low pressure switch will disallow start-up until pressure is adequate.
3. Press the power button; the solenoid will open and the unit will start operating.
4. After water is flowing from the concentrate line, adjust the concentrate control valve to obtain designated flow for the specific model (see Table 2-2 on page 2).
5. If required, adjust recirc control valve to meet desired flow rates (see Table 2-2 on page 2).
6. Allow the unit to run for 30 minutes to ensure proper flushing of system.
7. After the flush time is over, press the power button OFF.
FIGURE 10-1: CONTROL VALVES
CAUTION
To prevent concentrate from precipitating and causing irreversible fouling of the RO membrane, do not operate the system with the control valve completely closed.
8. Redirect the permeate line to the desired location.
NORMAL OPERATIONS
1. Turn the power back ON. After the pump starts, adjust the control valve to the desired flow/pressure (not to exceed 150 psi).
2. The recycle valve may now be adjusted to achieve desired recycle flow rate, ensuring concentrate flow rate is as specified.
SHUTDOWN
1. Press the power button to shut unit OFF. Close the isolation valve if it is installed on the feed line.
2. If the unit is to be shut down for more than one week, a membrane preservative should be used. To accomplish this, perform 30 second flush using cartridge filter insert (see page 14 for more information). After 30 seconds, press the power button OFF, and close the concentrate valve. This will hold the preservative in the pressure vessel.
3. When the system is restarted after an extended shutdown, follow initial system start-up procedures.
CAUTION
Do not exceed recommended maximum recovery.

Maintenance information
MAINTENANCE
MAINTENANCE TIPS
Maintain proper operating conditions:
• Do not exceed 150 psi on the system inlet pressure gauge.
• Do not over use recycle fl ow. This can cause premature scaling of the
membrane. A proper concentrate fl ow is required for a long membrane life.
• To ensure no chlorine reaches the RO membranes, test the water from
your carbon fi lter periodically for chlorine break through. To do this, a sample could be obtained by briefl y removing the Feed TDS probe at the downstream side of the cartridge fi lters. Brief power ON/OFF will be needed to perform this.
WHEN TO CHANGE CARTRIDGE FILTERS
Cartridge fi lters (both sediment and carbon) should be changed regularly to maintain proper pressure and fl ow.
The carbon fi lter removes chlorine and will exhaust its capacity over time. This is dependent upon feed source concentration and fl ow rate. Check chlorine removal effi ciency regularly.
Change the fi lters when the difference between the two cartridge fi lter pressure gauges increase by 10 psi over the initial pressure difference. For example, if initial readings are 60 psi in and 58 psi out, the difference is 2 psi. Therefore, when that difference reaches 12 psi, it is time to replace the sediment and carbon cartridges.

DriSteem replacement part number 550026-004.
FIGURE 11-2: 4" X 10" BIG BLUE DECHLORINATOR CARTRIDGE
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 it causes loss in water output or loss of salt rejection, or both. Elements should be cleaned or replaced whenever the water output rate drops by 10 percent from its initial fl ow rate (the fl ow rate established during the fi rst 24 to 48 hours of operation) or when TDS in the product water (permeate) rises above 50. Use the factory mounted TDS sensor located on the right side of the system.
It should be noted that the water output rate will drop if feed water temperature decreases (about 1.5% per °F). This is normal and does not indicate membrane
fouling. A malfunction in the pretreatment, pressure control or pump can cause a drop in feed water delivery pressure, feed water fl ow, product water output, or an increase in salt passage. If such adjustments are needed, the element may not require cleaning.
