TROUBLESHOOTING Heat Pump Fails to Operate... Is the display illuminated? If not, ensure the main breaker (located at the power supply panel) and the disconnect switch (located near the heat pump) are both turned ON. Is the code “FLO” displayed? If so, check to be sure that the circulating pump is operating and the filter is clean. There may also be a valve positioned incorrectly allowing water to bypass the heat pump. Be sure water is flowing through the heater. Is the Pool or Spa thermostat selected for the correct body of water to be heated, and have you tried selecting a higher temperature setting? If not, the actual water temperature may be above that of the selected thermostat. Raise the desired water temperature above the actual water temperature; the fan should start, and after approximately four (4) minutes, the “Heating” light should illuminate. If the heat pump still fails to start, and the unit is not in defrost (heat-only unit defrost display code is: “FS”), contact AquaCal Customer Support: 800-786-7751. Heat Pump Running... but is it Heating? Is the air blowing out of the top of the unit noticeably cooler than the surrounding air? (With heating indicator light illuminated, a 9°F to 12°F difference is typical.) If not, contact Aqua- Cal for service at: 800-786-7751. But first, be sure all air coil surfaces are free from obstructions– low roof overhangs, landscaping, walls, fences, etc., can restrict air flow. The heat pump needs good airflow to operate at peak efficiency. How many hours/day does the circulating pump operate? Cooler weather conditions, or heating to a higher than normal temperature, may necessitate running the heat pump for a longer period of time. Was the heater sized considering the use of a pool blanket (check with installing dealer)? A blanket can be useful in permitting shorter run times, in turn leading to substantial energy cost savings. What is the outside air temperature? The heat pump may be in the defrost mode if air temperatures are below 50°F. With Heat-Only models, if the heater is in defrost, the code: ”FS” will be displayed. If air temperatures are not cold, but the heater remains in defrost, contact AquaCal Customer Support at: 800-786-7751. Water Coming from the Heat Pump... Is it a leak or just condensation from normal operation? Here's how to find out. Test the water draining out the heater base for the presence of the sanitizer being used in the pool or spa. Using a water test kit, or a test strip, check a sample of the water for chlorine or bromine. If the sample tests positive for sanitizer, call AquaCal for service at: 800-786-7751. If the test is negative, the water is probably harmless condensate. Or, as an alternate method, shut the heat pump off, leaving the circulation pump running. Within a few hours, there should be a marked reduction in the amount of water seen around the bottom of the heat pump. If the water appears to be drying up, the water is probably harmless condensate, indicative of normal operation. NOTE: The water test method will not be effective if an ionizer or ozone generator is being used to produce the sanitizing agent. CAUTION! If after testing, a water leak is suspected, immediately shut OFF the water pump and contact AquaCal Customer Support: 800-786-7751.
