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 "FS" 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 "HP", "HP3", or "FLO" 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 "FLO" 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 further detail on these analyzer codes.

MAINTENANCE

WARNING: DISCONNECT ELECTRICAL POWER TO UNIT BEFORE STARTING ANY MAINTENANCE TO

PREVENT SERIOUS INJURY FROM SHOCK.

Protecting your Heater

• Keep your pool filter system clean and free of restrictions to ensure proper water flow.

• Check water chemistry regularly. Misuse of chemicals will cause permanent damage to your heater and

other pool equipment. Manufacturers can void warranties for damage as a result of poor water quality.

• Free airflow is essential. Keep the evaporator coil clean and free of weeds, leaves, glass clippings, dirt

and other debris that will decrease the airflow. Keep fences and shrubs away from air inlets (sides and

back of heater).

• Frequent rinsing of the evaporator with fresh water will remove build up from its surface. Always

spray the coil gently with a regular garden hose being careful not to bend aluminum fins.

• Regular cleaning of the cabinet will improve its appearance and extend the life of the finish.

Winterizing

When the heater is exposed to freezing temperatures, it is essential that all water within the unit be properly

drained. When water freezes, it expands, damaging piping.
