below 100/200 VAC
Contact a pool professional.
144
Low Salinity (below 2.0 gpl)
Add salt to pool to achieve 3.0 gpl (see
Section 4.7
).
145
High Salinity (above 4.0 gpl)
Backwash filter if a DE filter is installed. Partially
drain pool and dilute with fresh water until salinity
returns to 3.0 to 3.5 gpl.
170
Possible Front board service condition or unit not
correctly wired to 115 VAC
Contact an authorized service representative.
171
Possible Backboard service condition
Contact an authorized service representative.
172

not regulated or unit not correctly wired.
Unit wired to improper AC voltage. Contact a pool
professional.
174
Pool Temperature is too high for operation of AquaPure
Flow/ Salinity Sensor indicates water temperature at
sensor above 108 F. Reduce water temperature.
175
Flow Sensor air lock condition or very low salinity
Verify proper Flow/Temp/Salinity Sensor installation
(see
Section 3, Figure 12
). Check salinity with
Myron “L” meter calibrated for NaCl or test strips.
Add salt as necessary (see
Sections 4.5 through
4.7
).
