Troubleshooting
CAUTION
Hazardous voltages are present when power is applied to the controller. Pressing the Power key
DOES NOT remove these voltages. The power must be disconnected from the power source.
When connecting or disconnecting any wiring to the unit, be sure the power is turned off at
disconnect or breaker. Lock out/Tag out rules may apply.
Note that if fuse F1 or F2 is blown, none of the outputs will operate. If fuse F3 is blown, the
Controller will be inoperative. Refer to Figure 2 for the location of components.
This troubleshooting guide can assist in identifying common operating problems that may be experienced with the
machine. The operator can easily correct many of these problems. For those that persist or are not understood, contact
the Pentair Technical Support Center. Have the following Information available when calling the Customer Support
Center:
1. Installation and start-up checklist
2. Detailed description of problem
3. Operation Log

Machine not operating.
Page 20
Possible Causes
Remedies
Low membrane pressure.
See possible causes for low operating
pressure.
Dirty or fouled membrane elements.
Flush and clean the membrane elements.
Operating on cold water see temperature
correction table.
Install a hot/cold feed water tempering valve
if more permeate flow is needed. Operate at
higher feed water temperature up to
72 –77°F (22–25°C).
Membrane elements installed backward or
damaged concentrate seal.
Install membrane elements in the direction
of fluid flow. Flush and clean the machine
immediately.
Flow meter inaccurate.
Check the flow rate manually with a
stopwatch and calibrated container.
No power to machine or display.
Check the controller internal fuses and check
circuit breakers. Measure the voltage. Check
electrical outlet.
Defective board in controller.
External contacts have shut machine down.
Check for closed contacts - tank full, pretreat lockout and pressure fault.
Thermal overload in motor has tripped.
Allow the machine to cool. Check the feed
water supply and/or amp draw to the motor.
Motor and/or pump not operating properly.
See pump instructions. Contact Pentair for
possible repair or replacement.
Check Fuses F1 and F2.
Low pressure condition has turned OFF
machine. The low pressure LED will flash.
Check for minimum inlet pressure and push
power button twice.
See low operating pressure.
Tank level switch has shut off the machine.
If tank is full LED will be on - wait for tank to
empty. If LED is flashing the control is in a
delayed restart for up to 15 minutes
Fuse F3 bad.
The water quality display will not be lit.
Check or replace fuse F3 located below the
transformer.
No power at terminals L1 and L2.
Use VOM meter to check for power.
Control board defective.
Check for power at terminals L1 and L2. If
power is present control board may need
replacing.
