SYSTEM OVERVIEW

National Pride Equipment has developed and manufactured a proprietary RO System to provide a spot free rinse for car wash applications.
This RO System has been engineered to allow for a long longevity of issue free operation and low life cycle cost for the operator. The system utilizes commercial low temperature (high efficiency) RO membranes which operate at low pressure. In addition, all the components (chlorine filter, sediment filter, pumps, etc.) have been selected to improve the system reliability, minimize energy use and reduce required maintenance.
Please review the entire Manual prior to installation, start-up, servicing or operating the RO System. This manual will include step by step instructions, general overview, replacement parts for the system and overall guidelines.

TROUBLESHOOTING

Equipment

Improperly pretreated water can cause the membrane to have low water production.

Check Pressure Pre-Membrane

if Pressure Pre-Membrane is not maintained between 120-200 psi, loss will occur

Unable to Keep Pressure Pre-Membrane Between 120-200 psi| Check Reject Control Valve

With the RO running, shut off the reject control valve. Pressure should climb above the minimal pressure. If pressure does not increase, pinch off RO drain hose. If pressure still does not increase, the pressure pump needs to be replaced. If the pressure does increase, the reject control valve needs to be replaced.

Spot Free Water is Spotting| Check Product Water TDS

Test the product water as it is being produced. Sample the water as it moves to the storage tank. If the TDS is high, it could mean the membrane has been compromised.

Check Product Water TDS

The storage tank is an atmospheric storage container which can make it prone to the contamination. Routine cleaning of the tank will eliminate this problem.

RO Display Shows TANK FULL When the Tank is Not Full| High Level Float Switch is not Working

Using a jumper wire, jump the tank float terminals 15 & 16. If the RO does change to RO running, check wires from control box to float switch. If wire is OK, replace high level float switch.

** Check RO Controller’s Smart Relay is working. If it is not working, check the source power.

Blown Fuse in the Control Box
Check if either of the fuses look blown. If blown, replace the fuse.

RO Fault Condition Exists
The Production Pump will not start for the displays of TANK FULL, LOW FEED PRESSURE or BAD FLOAT.

High Level Float Switch is not Working
Add a jumper wire to the tank float switch terminals 15 & 16.
If the RO pump does not stop replace the smart relay.
If the RO Pump stops, replace the high level float switch to fix the issue.

RO Display Shows High TDS| Check Product Water TDS
Test the product water as it is being made. Sample the water as it goes to the storage tank. If the TDS is high it could mean that the membrane has fouled.

Check Storage Tank TDS
The storage tank is an atmospheric storage container which can make it prone to the contamination. Routine cleaning of the tank will get rid of this problem.

MAINTENANCE

System Maintenance Log
The operation and maintenance of an RO machine requires regular data recording and routine preventative maintenance. It is vitally important that the daily log sheet be filled out during each operational shift of use. A startup sheet / log should be filled out containing the informational facts about the operation of your machine. These records are kept strictly for reference. If you have questions concerning the operation of your machine or the method of the data recording, contact the manufacturer.
NOTE: A log is included with this manual.

System General Maintenance Guide
As a part of the routine maintenance program, it is suggested that performance data of your RO System is recorded on a regular basis. By recording the performance data, diagnosing and performance problems at a later date will be much easier.

Replace Pre-Filter Cartridges
The standard rule is that once a month the 5 Micron pre-filter should be replaced. The frequency can very depending on the production demands of the RO System. This filter protects the membrane elements from particles, which me be located in the feed water.
NOTE: A Pressure drop of 8 psi or more during operation indicates that the pre-filter cartridge needs replacing. Use filters rated at 5 micron or less.

Membrane Element Replacement
Membrane life expectancy will very from site to site depending on the water quality. TDS reading of 30 or less is considered to be spot free. Anything above this reading, the membranes should be replaced.
