Section VI Service & Troubleshooting
For personal safety and equipment reliability, the following procedure
should only be performed by a qualified technician. Contact our Ser-
vice Department for assistance (see Preface, After-sale Support).
Algae
To restrict the growth of algae in the reservoir, it is recommended that the
reservoir cover be kept in place and that all circulation lines be opaque. This
will eliminate the entrance of light which is required for the growth of most
common algae.
We recommend the use of Chloramine-T, 1 gram per 3.5 liters.
Checklist
Unit does not start when turned on.
Check the unit's circuit breaker. For units with the GFI option, be sure the
GFI is in the ON position before closing the circuit breaker and turning on
the unit.Check fault messages.
Check fluid level in reservoir.
Check power supply.
No/poor controller display
Open up the top panel and locate 1INST. Turn the plastic pot screw .
(labelled R35) in the middle of 1INST to adjust the intensity.
Pump does not start.
At least one flow sensor must be set greater than zero for the pump to
come on.See page 14.
Poor pump performance on initial start up .
The electrical phase may be wrong. Open the top of the unit and observe
the pump's rotation. If it is wrong, shut the unit down and disconnect it from
its power source. Swap any two AC line conductors.
Unit continues to run for a short period and then stops.
Check reservoir level. The unit has a nominal evaporation rate of up to 2.5
gallons per day. Ensure the autorefill system is installed. Also, check total
system for leaks.
Make sure unit running on proper voltage.
