NOTE: For water samples over 100°F (38°C) subtract 0.3 from pH result or, for the most accurate result, wait until water sample is below 90°F (32°C) to test.
Remove salt residue daily. Salt will damage the meter and cause inaccurate results. See CLEANING section in manual.

DOS & DON’TS

Hold syringe vertically when filling disks.
Do not fill disk while in the meter. Fill disk on clean, dry surface.
The disk should not contain any large air bubbles. Air bubbles will result in erroneous results.
Only the Universal Disk Cover (Code 1719) can be used with the WaterLink Spin Touch.
Empty syringe of previous sample before filling with next sample.
Remove filled disk from meter after testing.
Store disks at 70°-80°F/21°-27°C.
Keep the chamber clean and dry. Gently swab LED and photodiode lenses located around the hub with a cotton swab dampened with streak-free window cleaner. Do not use alcohol. It will leave a thin film over the lenses when dry.

FILLING: SINGLE-USE DISKS

When the syringe is placed in the water sample, and the plunger is pulled all the way up, the syringe will hold more than enough water sample to adequately fill the disk. Hold the syringe vertically and insert the tip into the fill hole in the disk. Press the plunger slowly and smoothly to fill the disk.

SINGLE-USE DISKS 01

Fill the disk using slow, even pressure. The sample water will fill the spaces between the baffles in a counterclockwise order. Each space will fill from the bottom to the top. Sample water should be added until the sample water in the fourth chamber fills to the top of the chamber slightly past the embossed fill line. It is OK to fill slightly past the fill line.
Do not overfill the disk. If the disk is overfilled, sample water will flow out of the overflow hole in the center of the disk. The disk is not leaking. Dry the disk and run the test.
Do not under fill the disk. If the disk is under filled, the reagent chambers will not fill entirely and results will be inaccurate.
Do not introduce air bubbles into the disk. The reagent chambers will not fill entirely and results will be inaccurate. As soon as a bubble starts to form, pull back on the plunger to draw the bubble out of the disk. Begin the filling process again.
Wet disks should be dried thoroughly with a lint free wipe. The disk should be handled by the edges.
Disks should be filled and used within 10 minutes. They cannot be filled ahead of time.

FILLING: MULTIPLE-USE DISK

When the syringe is placed in the water sample, and the plunger is pulled all the way up, the syringe will hold more than enough water sample to adequately fill the disk. Hold the syringe vertically and insert the tip into the fill hole in the disk. Press the plunger slowly and smoothly to fill the disk.

MULTIPLE-USE DISK 01

Fill any unused section of the disk using slow, even pressure. Add the sample water until the Blank Chamber is full and the Over Flow Chamber is partially filled.
Do not overfill the disk. If the disk is overfilled, sample water will flow out of the vent hole in the center of the disk. The disk is not leaking. Dry the disk and run the test.
Do not under fill the disk. If the disk is under filled, the blank chamber will not be full. The reagent chambers will not fill entirely and results will be inaccurate.
Do not introduce air bubbles into the disk. The reagent chambers will not fill entirely and results will be inaccurate. As soon as a bubble starts to form, pull back on the plunger to draw the bubble out of the disk. Begin the filling process again.
Wet disks should be dried thoroughly with a lint free wipe. Handle the disk by the edges. Between tests store the disk on a flat surface. Do not agitate a partially filled disk to avoid leaking and contamination. Partially used disks should be discarded at the end of the day.
Disks should be filled and used within 10 minutes. They cannot be filled ahead of time.
