Purifier Output Test

WARNING:

USE EXTREME CAUTION IN THE USE OF THE MULTIMETER. IMPROPER USE OF THIS DEVICE CAN RESULT IN INJURY OR DEATH. FOLLOW ALL SAFEGUARDS SUGGESTED IN THE OWNERS MANUAL FOR THE MULTIMETER IN ADDITION TO NORMAL SAFETY PRECAUTIONS IN DEALING WITH ELECTRICAL CIRCUITS. DO NOT USE THIS DEVICE IF YOU ARE UNFAMILIAR WITH ELECTRICAL CIRCUITS AND TESTING PROCEDURES.

FOLLOW THE METER MANUFACTURERS INSTRUCTIONS CAREFULLY AND COMPLETELY. OBSERVE AND FOLLOW ALL CAUTION WARNINGS!

NOTE: For ease of testing, we suggest the multimeter should be a digital auto-ranging device with auto polarity.

Purifier Output Test With Electrodes

[ ] Before starting the test, check the following:

1. Electrodes are clean and at least 1 1/2 inches long.
2. Make sure electrodes are connected to the system via the black cord.
3. Verify the electrical connections are functional.
4. Determine the Model number. (If necessary contact the factory.)
5. For the Model 5001 make sure the Flow light is not illuminated when the pump is running in the Manual mode.
6. Click for instructions to determine the Purifier Board Revision per Tech Bulletin 2001-1.

[ ] Turn all power to the unit OFF. On Model 5001 the Auto/Manual switch must be in the "Auto" position.

[ ] Turn Purifier Output knob to the "0" or the "OFF" position.

[ ] Disconnect one lead from unit to the electrodes, at the electrodes. Connect the multimeter and the calibrating resistor (if applicable) as shown in Figure 1. The resistor and test lead can be obtained from Wailani at no cost less shipping. (Order calibrating resistor.)

Figure 1

[ ] Set switches on the meter to measure 10 or 20 amps DC current.
Verify leads to the meter are hooked up properly, the 10 or 20 amp scale usually requires the leads to be in special positions.

[ ] For Model 1500 and 2001 - Turn the pump on and the unit should turn on.
For Model 5001 - Turn on the power to the unit. Place the Auto/Manual switch in the Manual position. The pump should turn on. Verify "flow" (actually a no flow indicator) light is off.

Meter should read less than 0.02 Amps . (20 ma)

[ ] On the Model 1500 set the output to 30%.
On the 2001 and 5001, turn the Output knob so that the 50% light is illuminated on the front panel.

For a Model 1500 unit the reading should be between .070 and .125 (70 and 125 ma)
On the 2001 and 5001 the meter should read between 0.2 and 0.3 amps. (200 and 300 ma)
On the 2051 or High Output purifier the meter should read between 0.3 and 0.4 amps.(300 and 400ma)

[ ] Turn Output knob to "100" (full cw).

The Model 1500 should read between 0.30 and 0.40 (300ma and 400ma).
For the 2001 and 5001 units, the meter should read between 0.450 and 0.525 amps. (450 to 525 ma)
For the 2051 or high Output purifier the meter should read between 0.700 and 0.800 amps. (700 to 800 ma)

[ ] Wait about 3 1/2 minutes and polarity on the meter should change. (+ and -). The Power indicator will change color about every 3 1/2 minutes.
( If the unit is in the “test” mode; the polarity will change more rapidly.)

[ ] Turn the power off to the unit. Disconnect test leads and resistor.

[ ] Return electrode lead to the Purifier chamber.

[ ] Return output knob to "0" or previous setting.

Troubleshooting Procedure

Connect the system and the calibrating resistor as shown below in Figure 2. Retest the system per the instructions above.

Figure 2

If the tests now pass there is a problem with the electrode assembly.

1. Make sure the electrodes are clean.
2. Make sure the electrodes are least 1 1/2 inches long.
3. Check the electrical connections on the top of the electrodes and the connections on the black cord coming from the system.
4. Verify electrodes are installed properly in the water flow and the Purifier chamber is properly installed.

If reading is always less than 0.01, then no ion current is flowing:

1. Verify power is being applied to the system.
2. Verify the fuse on the Purifier circuit board is good.
3. On the 5001 system - Verify "flow" light is off and the Freeze Guard (if so equipped) is not activated.
4. Verify the Check Electrodes light on the front panel is not illuminated. It turns on when the electrodes need cleaning, the electrodes need replacing or an "open" in the path from the output of the Purifier circuit board through the electrical connections to the electrodes is present.
5. Verify electrodes are at least 1 1/2 inches long.
6. Check for continuity on electrode cords and connections.

If output is lower than specified:

1. Check water calcium hardness for "soft water". Hardness must be more than 125ppm.
2. Make sure the electrical connections are clean.
3. Verify the electrodes are clean.

If there is a reading for 3 1/2 minutes, then it goes to zero or does not change polarity:

1. Verify continuity from the connection in the box for the electrode cord through the cord and connection on the end of the cord.
2. The relay on the Purifier circuit board is most likely not working. Contact the factory.

If the above measures do not repair the unit; then contact Wailani Water Products.
