Automatic Shut-Off - Spectrum PTL RO System Installation Instructions Manual

C C HECK VALVE
The check valve is vital for proper operation of the Reverse Osmosis system. The check valve ensures that the product water is flowing
in the proper direction, and does not allow it to flow backwards.

AUTOMATIC SHUT-OFF

The automatic shut-off conserves water when the storage tank is full by turning the system off until more product water is needed.
REVERSE OSMOSIS TROUBLESHOOTING GUIDE
LOW WATER QUANTITY
Possible Cause
Incoming water temperature is cold
Incoming water has extremely high level of Total Dissolved Solids (TDS)
Low incoming water pressure.
Carbon pre-filter is clogged.
Reverse Osmosis Membrane is fouled
Air pressure in holding tank is incorrect.
Solution
The water temperature is one of the key factors in the performance of the PTL-RO membrane. The
higher the temperature, the higher the flow rate, and vice versa. All PTL-RO Membrane elements
o
are tested and rated at 25 C. Ensure the PTL-RO is installed in a heated area of the home.
Incoming TDS level is one of the key factors determining the flow rate of the PTL-RO membrane.
More TDS requires more time for the membrane to remove – no solution is required. Ensure
incoming TDS does not exceed 2000 ppm.
Incoming water pressure is one of the key factors determining the flow rate of the PTL-RO membrane.
Higher pressure will enable a higher flow rate. Pressure must be above 40 PSI for proper operation.
You may need to install a Booster Pump or Permeate Pump if your pressure is below 40
Replace Filter with model number PTL-CB
Make sure incoming water pressure is within operating limits. Make sure drain line is not clogged.
Correct cause of fouling or replace RO Membrane.
Empty water from holding tank. Air pressure in valve stem should be between 5 - 7 PSI. Increase psi
similar to adding air to bicycle tire.
