X. OPERATING PARAMETERS
& SAFETY MEASURES:
The following conditions for feed water supply
MUST be met or Warranty will be void.:
1. Unit MUST be connected to a municipal or well water
source that is treated and tested on a regular basis to
insure water is microbiologically safe.
2. Operating temperatures:
Maximum: 105 °F ( 40.6 °C )
Minimum: 50 °F
( 15 °C )
CAUTION!! DO NOT ALLOW SYSTEM TO FREEZE. The membrane always
contains water and will be destroyed if frozen.
3. Maximum Operating Pressure MUST NOT EXCEED 120 PSI.
(
Waste out from membrane housing line , and before flow restrictor)
WARNING!! Warranty voided and manufacturer assumes no responsibility
for damage to system or property if pressure exceeds 120 PSI.
4. Inlet Pressure:
Maximum: 80 PSI
Minimum: 40 PSI
At pressures lower than 40 PSI production and quality of water
supply will be reduced and operating at pressures greater than
120 psi may be severe damage to the system, for which it is
recommended to measure the following parameters.
5. Turbidity: < 1 NTU
6. pH Range : 4 – 11
7. We recommend the following parameters NOT TO EXCEED:
•
Total Hardness: NOT TO EXCEED 7 grains/gal ( 120 ppm )
•
Sulfide, Iron and Manganese: < 0.001 ppm
•
Residual Chlorine In Water Supply: < 1.5 ppm
8. Recommended Total Dissolved Solids (TDS)
NOT TO EXCEED 1,000 ppm.
XI. TROUBLESHOOTING AND SOLUTIONS GUIDE
Symptom
Posible Cause
Solution
LOW QUANTITY OF WATER
FROM HOLDING TANK
Feed water valve is plugged or closed.
Open the feed water valve or unclog.
Pre-filter o post-filter are saturated or clogged.
Replace Filters.
Low incoming water pressure.
Your booster pump may not be operating properly.
If damaged correct or replace. Check the low pressure switch
is operating correctly.
Reverse Osmosis Membrane is fouled.
Make sure feed water pressure is within operating limits. Make sure
drain line is not clogged. Check the water quality parameters
and correct the cause of fouling and replace RO membrane.
Air pressure in holding tank is incorrect.
Empty water from holding tank. Air pressure in valve stem should be
between 8 - 10 PSI.
Air Bladder in Holding Tank is ruptured.
If the tank has a way to change the membrane do it, or replace for a
new tank.
Holding tank valve is closed.
Open tank valve.
No water to drain. Drain Flow Restrictor is clogged..
Replace Drain Flow Restrictor.
Check Valve on RO Membrane Housing is stuck.
Replace Check Valve.
The Solenoid Valve in the feed it is not operating properly.
Verify if you are getting electrical power and for any obstruction not
allowing water passage.
