1. INTRODUCTION
Whatever your purified water application, the PROPAK
®
system is the ultimate solution to providing a spot free rinse by removing mineral salts and other impurities. The cleaning of automobiles, trucks, aircraft, windows, and even glassware has dramatically improved from this technology.
PROPAK
®
systems are designed, manufactured, and tested to give years of trouble free service with a minimum of maintenance. There is no other system available that incorporates the features and durability of components found in PROPAK
®
reverse osmosis equipment.
As with all products, the customer has certain responsibilities to insure that the system operates under proper conditions. Installation, start-up, and maintenance instructions must be followed closely. It is also important that the system log be kept accurately and current.
2. IMPORTANT TERMS
Reverse Osmosis
A reversal of the natural phenomenon of osmosis by application of hydraulic pressure greater than the osmotic pressure in water (due to dissolved solids). The causes the water molecules to flow through a semi permeable membrane leaving the dissolved substances behind.
Feed Water
The water supply that is fed in the reverse osmosis membrane under pressure for processing. Typically softened and conditioned to meet the parameters required by the membranes.
Thin Film Composite Membrane (TFC)
A special type of high rejection, long lasting, cleanable membrane that is resistant to most adverse water conditions.
Recovery
The amount of product water as compared with the total amount of feed water. This will give a measure of the efficiency of operation. For example, starting with
10 gallons of feed water, if we separate 6 gallons into product water and reject 4 gallons, the recovery is
60%.
Reject Water (same as brine)
That portion of the feed water that does not pass through the reverse osmosis membrane, and carries the impurities to the drain.
Product Water
The pure water that has been separated from the feed water stream by the reverse osmosis membrane.
Pre-Treatment
Whatever alterations of the raw feed water are required to prevent damage to the membrane or more efficiently operate the membrane. This may include softening, carbon filtration, sediment filtration, addition of anti-scalant, etc.
Total Dissolved Solids (TDS)
Generally, the total amount of mineral salts which are dissolved in water.
Parts Per Million (PPM)
The standard measure of total dissolved solids.
Parts of dissolved material in one million parts of water. One pound of mineral salts dissolved in a million pounds of water would be one part per million.
Percent Rejection
The percentage of TDS removed from the feed water.
Typically, greater than 90% rejection is achieved with reverse osmosis.
Backup Softener
A small softener before the reverse osmosis system to insure soft water during regeneration or failure of the main carwash softener.
GAC Filter
Granular Activated Carbon media filter for removing chlorine from the water for protection of special composite reverse osmosis membranes.
Low Pressure Switch
A pressure sensing device that will turn off the reverse osmosis system if the feed pressure falls below a preset level (usually 30 psi).
Temperature Blending Valve
A special valve which blends hot and cold water to raise the water temperature for increased product water flow.

4. PRE-TREATMENT
WATER SOFTENER
For the most efficient operation of the reverse osmosis system, the unit should be operated on softened water (less than 1-grain hardness). Soft water from an existing main carwash water softener can be used provided sufficient capacity remains in the softener and:
1. The softener is designed such that continuous soft water can be supplied even during regeneration (e.g. duplex softener); or
2. A timer cutout shuts off the reverse osmosis system during conventional softener regeneration; or
3. It can be assured that the reverse osmosis system has filled the storage tank and shut off (e.g. early morning) when the softener is set to regenerate.
If the existing softener is old, unreliable, or cannot provide continuous soft water, it is recommended that a small backup or polisher softener be installed prior to the reverse osmosis system. Consult the factory for recommendations.
An alternative is to install a separate softener just for the reverse osmosis system. it should be capable of providing continuous soft water while the reverse osmosis system is operating, or a timer cutout should be installed to shut off the reverse osmosis system during softener regeneration. Consult the factory for recommendations.
CARBON MEDIA FILTER (for chlorinated water supply)
If a TFC type membrane is used and the water supply is chlorinated (don't guess – consult your water department), a properly sized carbon media filter must be installed prior to the reverse osmosis system
ADDITIONAL PRE-TREATMENT
Should the water analysis indicate other factors that would be harmful to the reverse osmosis system, the factory will make further recommendations as to additional pre-treatment equipment that may be required.
TEMPERATURE BLENDING VALVE
If the water temperature is low, the reverse osmosis system will not produce its full rated capacity (based on 70° F. feed water temperature). With these cold water conditions, a temperature blending valve may be installed to increase the feed water temperature and thus the output of the reverse osmosis system. The blending valve should be a special type supplied by the factory with a built in thermometer. It should be installed prior to the optional backup softeners (if used) and the GAC carbon filter (See Fig 2). Both the cold water and the hot water supplied to the valve must be soft (less than 1 grain hardness) if 50% recovery is expected.
Guidelines for the proper use of the temperature blending valve:
1. The maximum recommended operating temperature range is 70°–77° F., with 77° F. being the ideal.
2. Operate at the lowest temperature that allows the RO SYSTEM to meet the car wash's needs.
3. Never increase the temperature above 70° F. in an attempt to increase RO production. This may seem like a good move in the short term. However, it will probably lead to the following problems below:
1. The membrane may become fouled with hardness minerals due to the increase in membrane flux and greater tendency for scale formation.
2. The membrane may become fouled with alum or cationic polymers much more rapidly than if operated at 70° F. or below.
3. The membrane may become fouled with biological matter due to the elevated temperature which creates an environment conducive to the accelerated growth of bacteria.
All of these problems will decrease the output of the RO SYSTEM. Correction of these problems will require cleaning of the membranes at the very least. And if the conditions are allowed to continue for a prolonged period, the membranes may have to be replaced. None of these problems are covered under the system warranty.

5. INSTALLATION REQUIREMENTS
IMPORTANT
The PROPAK
®
system installation must conform to local plumbing, electrical, and sanitation codes. Obtaining permits and meeting codes is the customer's responsibility.
FOR WATER SUPPLY
Run a softened cold water supply to the vicinity of the reverse osmosis system location. Provide a ball or globe valve and a (female pipe thread) connection. If a temperature blending valve is used, run a softened hot water supply with valve and FPT connection.
See Figure 1 and Figure 2 for flow rates and suggested line size.
NOTE: The water supply must be continuously soft while the reverse osmosis system is running.
FOR ELECTRICAL
A disconnect or junction box (consult local electrical codes) should be provided in the vicinity of the reverse osmosis system with the following service:
PROPAK
®
Reverse Osmosis System
208-230/460 VAC, 3 Phase, with ground. (Single Phase for 1800 and 3000 models).
See Figure 6 for required Amp ratings. If your system included repressurization equipment, the electrical requirements will be greater.
Carbon Media Filter (if required)
115 VAC, 1 Amp, grounded receptacle.
FOR DRAIN
Use or provide a floor drain or a 1½" standpipe which ties into an existing drain having a proper trap and vent.
The reverse osmosis system and the carbon media filter (if required) require a drain connection. The drain flow from both of these units is pressurized so that the drain hose may be run fairly long lateral distances
(up to 25 feet) at elevated heights – up to 3 feet above the carbon filter drain connection and up to 10 feet above the reverse osmosis drain connection.
IMPORTANT
A properly designed air gap must be provided between the drain hose from the RO and GAC units and the sewer waste line in order to conform to plumbing codes. This prevents a cross connection which could result in contamination of potable water. An approved air gap is included in the installation kit option.

7. FLOAT SWITCH INSTALLATION PROCEDURE
NOTE: All the operations listed to install the float switches may be done with the tank lying on its side. Be
sure to remove any chips or other debris from the tank before filling with purified water.
REVERSE OSMOSIS (RO) SYSTEM SHUT-OFF – "TANK FULL" FLOAT SWITCH
Note: Blue and Black wire leads with Blue Color Band
Operation Description: The high water level control float contains one switch with a mechanical dead band action. The RO SYSTEM will turn on approximately 8" below the point it turns off.
Installation:
1. Access the inside of the tank through the manway or cover. Using a hole saw, drill a ¾" hole through the top of the tank near the high point (see Figure 5). Make to sure to prevent shavings from falling into the tank.
2. Adjust the weight on the cord sot that the bottom of the weight is about 6" above the top of the float. Snap the gripper wedge over the cord and secure the weight in this position.
3. Remove the hex nut from the cord grip fitting and push the free end of the float cord through the hex nut.
4. From the inside of the tank, push the free end of the float cord through the ¾ " hole and then through the cord grip as shown. Push the threaded end of the fitting through the hole and tighten the nut from inside the tank to secure the fitting.
5. Pull the cord out until there is about 10" left between the top of the weight and the inside surface of the tank.
6. Slide the seal, gripper, and fitting nut over the end of the float cord and up to the fitting body.
Secure the cord by tightening the fitting nut.
REPRESSURIZATION (RP) SYSTEM SHUT-OFF – "TANK EMPTY" FLOAT SWITCH
Note: Brown and Black wire leads with Red Color Band
Operation Description: The low water level control float contains one switch and serves as a low level safety shut-off to protect the repressurization system pumps.
Installation:
1. Access the inside of the tank through the manway or cover. On the opposite side of the tank from the RO shut off float switch, using a hole saw drill a ¾ " hole through the top of the tank near the high point (see Figure 5). Make sure to prevent shavings from falling into the tank.
2. Remove the hex nut from the cord grip fitting and push the free end of the float cord through the hex nut.
3. From the inside of the tank, push the free end of the float cord through the ¾ " hole and then through the cord grip as shown. Push the threaded end of the fitting through the hole and tighten the nut from inside the tank to secure the fitting.
4. Pull the cord out until, in a free hanging position, the bottom of the float is about 2" above the top of the water outlet bulkhead fitting. This will cause the RP System pump to shut off when the water falls to about 7" above the outlet fitting.
5. Slide the seal, gripper, and fitting nut over the end of the float cord and up to the fitting body.
Secure the cord by tightening the fitting nut.
ELECTRICAL HOOK-UP – RO/RP SYSTEM SHUT-OFF FLOAT SWITCH
1. Run the cords to the system control box through the cord grip adapter on the box, and connect the wires to the appropriate terminals – see Figure 6.
2. If the tank is located too far away for the standard cord to reach the system control box, install a junction box as shown in Figure 6. Run a 4 wire cord (for RO and RP floats) or a 2 wire cord (for
RO float only) from the system control box to the J-box. You may use ½" conduit with 2 or 4 individual wires as needed.
NOTE: If you are not using a PROPAK
®
RP System, consult the factory for appropriate connection points for the float switch.

8. CONTROL SYSTEM
RO SYSTEM CONTROL
The PROPAK
®
RO SYSTEM control function is accomplished by several integrated components. They have been selected for their proven performance and durability. Together they simplify installation, provide for long motor and pump life, protect the RO membranes from many common hazards, prevent system freeze-up, and allow the operator to monitor system performance. The parts are common to the industry and well understood by technicians or tradesmen. This translates into predictable long life and simple troubleshooting or service procedures.
CONTROL COMPONENT DESCRIPTION
Control Circuit Transformer
208-240/460-480 VAC primary – 24 and 16 VAC secondary @ 75 VA.
It is a fully encapsulated machine-tool style transformer with screw terminals, designed for continuous operation. The secondary 24 VAC operates the control circuit (solenoids, lights, and starters). The secondary 16 VAC supplies power to the PLC. The low voltage control power increases safety and reliability in moist or wet environments. Both primary and secondary are provided with circuit breaker protection. The secondary is configured as a grounded neutral circuit to allow safe interfacing to external control circuits, such as self-serve bay or automatic tunnel repressurization pump start signals.
Distribution Block
Provides a single electrical connection point in the RO SYSTEM control panel for single or three phase
230 or 460 VAC.
Motor Protection
All RO SYSTEM motors have independent circuit breaker protection in the control box. This provides local wire and motor protection and prevents interruption of other equipment. Typically a non-fused safety disconnect is all that is required by the installing technician.
PLC
The PLC (programmable logic controller) is the heart of the control system, reading the state of the switches and turning the solenoids, motors and lights on or off as required. Each input and output is wired via pluggable screw terminals and the ON/OFF state is indicated by an LED. The PROPAK
®
PLC is fully encased in a metal enclosure limiting exposure to moisture and stray wires typical of "board" based products. The outputs are heavy duty, rated individually at 8 amps continuous duty. The prominent heat sink and heavy-duty construction allows for operation in environments which can destroy more common electronics. The PROPAK
®
PLC is rated to operate from minus 22°–175° F. (many control electronics are not stable below 30° F. and may not turn on at all at colder temperatures). Shock resistance is 10 G minimum. The operating program is held indefinitely without power. A battery back-up will hold process data (operating hours, PRO-FLUSH timing) for at least 10 years.
TDS Transmitter
Designed as a stand alone instrument, it interfaces to the PLC through a 0-5 volt input. The transmitter is designed to be extremely stable over a wide temperature and TDS range for greater accuracy
Indicator Lights
All RO SYSTEM motors have independent circuit breaker protection in the control box
Panel Switches
All RO SYSTEM motors have independent circuit breaker protection in the control box

11. REQUIRED MAINTENANCE
The PROPAK
®
RO SYSTEM is designed to require a minimum of maintenance over its lifetime. The most prudent course of action is to monitor the system performance and take corrective action as soon as it is indicated. A daily log of key parameters is presented in Figure 8. Following the suggested course of action to correct variations and/or periodically reviewing the data with your authorized distributor will insure years of trouble free operation.
DAILY LOG PARAMETERS
FEED HARDNESS
TEST INTERVAL: DAILY
UNITS: COLOR STRIP, GRAINS PER GALLON (GPG)
NORMAL VALUE: GREEN, < 1 GRAIN
ACTION: Take a test sample form the valve at the pre-filter outlet. Do a quick test with a softener strip. If the result is green, write "green" in the log. If the result indicates hard water, use a hardness test kit to determine the exact hardness level. If less than 5 grains hard, shut the system down or set the reject flow to twice the product flow until soft water is restored. If the test shows greater than 5 grains, shut the RO
SYSTEM down until the problem is corrected.
PRODUCT TDS
TEST INTERVAL: DAILY
UNITS: PARTS PER MILLION (ppm)
NORMAL VALUE: < 10 ppm
ACTION: Read the TDS ppm value form the PROPAK
®
RO SYSTEM display (MODE 2). Sudden increases in TDS may mean that the membranes are becoming fouled. EARLY corrective action can prevent permanent damage and allow the membrane to be restored to nearly new condition.
NOTE: The PROPAK
®
RO SYSTEM will not operate at TDS levels above 40 ppm for more than
20 minutes.
PRODUCT FLOW RATE
TEST INTERVAL: WEEKLY
UNITS: GALLONS PER MINUTE (GPM)
NORMAL VALUE: SEE FIGURE 8.
ACTION: Read the PRODUCT FLOW METER on the top of the instrument panel. Read the value in GPM at the top of the float.
REJECT FLOW RATE
TEST INTERVAL: WEEKLY

FEED WATER PRESSURE
TEST INTERVAL: WEEKLY
UNITS: POUNDS PER SQUARE INCH (psi)
NORMAL VALUE: > 20 PSI
ACTION: Read the FEED PRESSURE GAUGE on the instrument panel.
NOTE: The Feed Pressure should be read when the RO SYSTEM is operating.
SYSTEM OPERATING PRESSURE
TEST INTERVAL: DAILY
UNITS: POUNDS PER SQUARE INCH (psi)
NORMAL VALUE: > 200 PSI
ACTION: Read the SYSTEM PRESSURE GAUGE on the instrument panel.
NOTE: The System Pressure should be read when the RO SYSTEM is operating.
WATER TEMPERATURE
TEST INTERVAL: WEEKLY
UNITS: DEGREES FAHRENHEIT (°F.)
NORMAL VALUE: 70° F.
ACTION: Read the TEMPERATURE VALVE from the PROPAK
®
RO SYSTEM display (MODE 3). If the system uses a blending valve, check the temperature gauge at the blending valve.
NOTE: The water temperature should be read when the system has been operating for at least 5 minutes.
SYSTEM OPERATING TIME
TEST INTERVAL: WEEKLY
UNITS: HOURS
NORMAL VALUE: N/A
ACTION: Read the OPERATING HOURS value from the PROPAK
®
RO SYSTEM display (MODE 1).
CHLORINE LEVEL (Cl
2
)
TEST INTERVAL: WEEKLY
UNITS: mg/l
NORMAL VALUE: 0 mg/l
ACTION: Take a test sample from the valve at the pre-filter outlet. Use a chlorine test kit to determine the presence of free chlorine. If free chlorine is detected, the carbon and gravel in the backwashing filter may have to be replaced. Prolonged contact (300 + hours) with chlorinated water will cause permanent deterioration of the membrane. The effect of chlorine on the membrane is cumulative.
NOTE: The chlorine level should be read when the system has been operating for at least a half hour.
OTHER DATA
Recording of this additional data will improve system performance monitoring.
• Date of last pre-filter change • Feed water TDS using hand-held tester
• Date of softener salt change • Date of last membrane cleaning
• Volume of salt added to softener • Results of last membrane cleaning
• Feed Water Pressure: After FEED SOLENOID comes on, but prior to RO PUMP running. Record with a slash in front of system running feed pressure. For example: 40/25
