SpectraPure

TROUBLESHOOTING GUIDE:

1. Low production rate:
a. plugged pre-filters.
b. low water temperature. ii. Heat feed water OR use higher GPD membrane.
c. low line pressure.
d. high TDS content.
e. fouled membrane.
f. plugged flow restrictor.
2. Zero production rate:
a. Missing flow restrictor.
b. Dried RO membrane.
c. Plugged flow restrictor.
3. Extremely high production rate:
a. Ruptured membrane.
b. Very high line pressure (> 80 psi).
4. Pressure gauge does not register pressure when the system is "ON":
a. Missing flow restrictor.
b. Pressure gauge screwed in too far.
c. Plugged pressure gauge orifice.
d. Defective pressure gauge.
5. Low deionization cartridge life:
a. Defective membrane.
b. Low pressure (< 40 psi).
c. High CO2 levels in water (> 5 ppm).
d. High TDS in feed water (> 1000 ppm).
e. High levels of silica, nitrates,
f. Bad or faulty DI cartridge.
g. High pH tap water (> 9.0).
h. Faulty monitor/probe.

Put flow restrictor in the yellow
line.
Unscrew pressure gauge one
turn and retest.
Clean orifice with a needle.
iv. Replace it.
i. Replace it.
ii. Use booster pump.
Aerate RO product water or use a
straight anion cartridge ahead of
DI cartridge. (Call Technical
Support)
NO EASY SOLUTION.
Use straight anion cartridge
ahead of mixed-bed for
phosphates etc. in tap water.
Acidify feed water to the RO
membrane to improve its
rejection.
Test and Replace if required.
