•As a final check turn on the city water valve to the By-Pass Panel and check the plumbing for leaks.

§5.2 PERFORMANCE VERIFICATION

Factory test data is supplied with the system. To ensure optimum performance, on-site data should be taken and compared to the factory test data. This data should be taken after the system has been flushed for one hour. Some deviations may be seen due to differences in feed water TDS and temperature between the site and factory. If you have already connected the product line to the tank, you will need to disconnect it ahead of the post carbon filter (if one is installed) to take product samples.

The following tests need only be performed if it is felt the system may not be performing as expected. The flow and TDS tests may be performed say after membrane replacement. The pressure switch tests can be performed periodically to insure operation at the preferred set points.

§5.2.1 FLOW TESTS

Determine the flow rates for both product and concentrate. Put the product line into a container and measure the volume of water that flows into it in one minute. Repeat the process with the concentrate (drain) line. These values should be in either gallons per minute or milliliters per minute. Product flow rates (at 77° F, 25° C) should be within 15% of the production rates given in §1.0 SYSTEM SPECIFICATIONS.

§5.2.2 CONCENTRATE TO PRODUCT RATIO

Compute the concentrate to product ratio (C:P) by dividing the concentrate flow rate by the product flow rate. This ratio should be between 2:1 and 5:1.

§5.2.3 TOTAL DISSOLVED SOLIDS (TDS) REJECTION

Using a conductivity meter (TDS meter) measure the TDS in both the feed water and the product water. Calculate percent rejection using the formula below:

(Feed TDS-Product TDS) ÷ (Feed TDS) × 100 = % Rejection

Rejection should be 85% or better. For example, where the feed TDS is 600 and the product TDS is 24, the percent rejection is

600-24) ÷ 600 × 100 = 96%.

§5.2.4 LOW PRESSURE SWITCH TEST

While the system is running gradually shut off the water supply to the system and observe the feed water filter gauge. The system should shut off when the pressure drops to about 12 psi. If the system does not shut off, either unplug the system or restore the water supply to the system.

DO NOT LET THE SYSTEM RUN WITHOUT THE WATER SUPPLY TURNED ON. PUMP DAMAGE WILL OCCUR. Refer to §7.1.1 for LOW PRESSURE SWITCH ADJUSTMENT.

§5.2.5 TANK PRESSURE SWITCH TEST

With the product line connected to the tank and with the system running, close the inlet valve to the tank. The tank pressure gauge should start to rise and the system should shut off when the
