Because evaporation accounts for about 70 percent of pool heat loss, the beneficial effect of using a pool
cover /solar blanket can be dramatic.
Wind Speed Reduction
Reducing wind velocity at the water surface reduces convective and evaporative losses. Fences, trees, hills,
or tall hedges close to the pool perimeter are effective windbreaks. Locate these obstructions to take
maximum advantage of their effectiveness as windbreaks, without shading the pool surface from the sun.
Defrost Cycle
The heat pump pool heater has automatic defrost. When the outdoor temperature drops below 40 °F, frost
may start to form on the evaporator coil. Frost buildup will be heaviest on humid days when the
temperature is between 35-40°. During the defrost cycle, the display will show "DEFROSTING" to
indicate that the unit is defrosting. During this time the fan is running and the compressor is inactive.
Internal Protection Analyzers
The heater is equipped with internal devices to monitor and protect the integrity of the unit. Should an
abnormal condition occur, these devices will interrupt the operation of the unit and may display the
appropriate code on the control panel.
• LOW WATER FLOW: Indicated by "FLO", "HIGH REFRIGERANT PRESSURE", or "3 HPS
STRIKES LOCKOUT" on the control panel. The heater is designed to run efficiently above twenty
(20) GPM. If there is insufficient water flow, the unit will shut down, protecting the compressor.
The usual causes for these conditions are a dirty pool water filter, a restriction in the return line
(i.e. skimmer), or improper valve positioning.
• NO WATER FLOW: Indicated by "LOW FLOW" on the control panel. When the filter pump is off,
or if the water flow to the heater is interrupted during the heating mode, the internal water pressure switch
will shut down the unit. When normal water flow resumes, the heater will automatically restart itself.
• Other analyzer codes include: "FL3", "LP3", "LP", "dPO", "PO", "dPC", "Pc", "PLE", "CSE" and
"SPi".
The TROUBLESHOOTING CHECKLIST on page 11 goes into detail on these analyzers codes.
