6. Maintenance

The innovateIT R.O. System has been designed to provide a long life and require minimum maintenance. The best method to

maintain this system is to take a few minutes daily to review and record the operational data from the system and examine

the unit for leaks or any indication of a mechanical or electrical fault.

If a change in performance or operation is observed, it is essential to take corrective action quickly to minimize the potential

damage to the membranes or other parts of the system.

There are elements of the system that will require replacement during normal maintenance actions. These items are listed in

the following section.

NOTE: The standard activated carbon blocks are highly effective in removing free chlorine from feed water that has been

treated with chlorine. However, chloramines are harder to remove and require special catalytic carbon blocks to remove the

chloramine.

Based on your municipal water supplier, water treatments vary signifi cantly across the country with many differing levels of

sanitizing agents used and variation throughout the year.

Please consult with innovateIT Car Wash Equipment LLC to determine the type of carbon block to use and the estimated

replacement interval as the dosing level in PPM, water pH, and chloramine mixture will greatly impact the performance of the

carbon blocks. If the estimated life of the carbon block is too short, innovateIT Car Wash Equipment will recommend the use

of a traditional carbon fi lter.

innovateIT uses a Catalytic Carbon Block to remove both chlorine and chloramine to maximize the longevity of the membrane.

Verify free chlorine/chloramine level on the outlet of the carbon fi lter manifold. This should be done every week, and the

carbon fi lter must be replaced if the unit is not removing the chlorine/chloramine from the municipal water (<0.10 PPM)

Some municipalities increase chlorine/chloramine levels for a few months each year to sanitize the distribution system so

verifying complete chlorine removal is critical to proper operation of the system.

6.1.3 RO Membrane System (Membranes and O-Ring Seals in Housing)

Clean or replace membranes when the TDS levels exceed 20PPM, or the RO generation fl ow rate reduces by 20% of the de-

sign fl ow rate.

Membrane failures are normally initiated by free chlorine "breakthrough," which damages the membranes by creating holes in
