Guidelines (cont.)
Condensation
All heat pump pool heaters will have condensation. It is typical to have as much as 6-8 gallons of condensation or water per hour, during a warm, humid day. Do not mistake this for a leak.
If you are not sure the water is a leak or is condensation, there are two ways to check this. First, use a pool test strip to see if there is any chlorine or bromine in the water. If there is, contact the factory for service. Second, you can turn off the heater, leave the filter pump running and see if the water stops. If you do not see additional water, then the original water was condensation.
Pool Blankets
A pool blanket has been proven to greatly reduce the heat loss in the pool and will save as much as 50% - 60% in your heating bills. During the start of the swimming season and the end of the season the heater may not be able to maintain your desired temperature without the use of the pool blanket.
Seasonal Shutdowns
At the end of your swimming season you may have freezing weather conditions. The unions (provided) must be disconnected to drain any water in the pipes. Failure to do so may cause the heat exchanger to expand and crack. This will void your warranty.
If you live in an area that does not have freezing weather conditions but are subject to extended periods of non-use, allow the filtration system to continue to run water through the heater. Or you can drain the unit of all water.
Pool Openings
If at the end of the previous season you disconnected the unions, be sure to connect them before you turn on the filtration system. Once the pool has been cleaned and the unit has been checked for leaks, turn the power on the heater and set the thermostat to the desired temperature.
Note: It may take up to three days to reach the desired temperature during the opening of the swimming season. Without a pool blanket, it may take even longer and may not reach the desired temperature until later in the season.
Weather Conditions
Weather conditions play a big part in the operation of the heater. Low outside ambient temperature, high winds, low relative humidity, and a large amount of shading on the pool will all have an effect on how much time it takes to heat the pool and how much time it might need to maintain the desired temperature. Once the outside ambient temperature drops below 50ºF (38°F for h/c units), the heater may not operate.
Troubleshooting Guide
If the heater is not operating during the initial start-up, check to see if it has been installed properly, per this owner’s manual. Make sure the breaker has been sized properly. The following are conditions to check before calling AquaPRO® Systems for a service:
Diagnostics
ALL MODELS (except PRO1100)
The display located on the heat pump has diagnostic codes, which help explain any reason for the heater not to be operating properly. The following are the diagnostic codes and the reasons for them appearing:
FLO: This code means “Pressure Switch” or water pressure switch. This means there is not enough water flow to activate the water pressure switch. The cause could be from a clogged filter or a manual by-pass is in the wrong position and is not allowing water into the heater. Once the filter has been cleaned or the by-pass has been changed to allow water to flow through the heater, the FLO display will go away and the water temperature will appear on the display.
HP: This code means “High Pressure” or high pressure switch. Either there is low water flow or high ambient temperature or both. Again, the filter could be clogged and not allowing enough water flow to pass through the heat exchanger and allow the heat to be taken away fast enough, or a by-pass is not in the proper position. Once the filter has been cleaned or the by-pass has been re- positioned, the display should return to the temperature of the water.
LP: This code means “Low Pressure” or low pressure switch. Either the outside ambient temperature is below 50°F (38°F
for h/c units), which is too low for the heater to operate, or the unit is low on refrigerant. Once the outside temperature has risen above 60ºF, and the LP code remains, call the factory for repair.
PSd: This code means there is a pool sensor defect. Please call AquaPRO® Systems to arrange service for the heat pump.
DSd: This code means there is a defrost sensor defect. Please call AquaPRO® Systems to arrange service for the heat pump.
LP3: This is like the “LP” described above, however the unit has shut down because this fault has happened 3 times within a 24 hour time period. If the ambient temperature is below 50°F (38°F for h/c units), the problem will most likely persist until the ambient air temperature rises above 50°F. Pressing any of the buttons on the front control panel will restore the unit to its normal operating mode. If the ambient air temperature is not the issue and the heat pump continues to display “LP” or “LP3”, please call AquaPRO® Systems to arrange service for the heat pump.
HP3: This is like the “HP” described above, however the unit has shut down because this fault has happened 3 times within a 24 hour time period. Please check your pool’s plumbing, valves and pump / filter system for blockages or flow restrictions, as this is most likely the cause for the fault. Pressing any of the buttons on the front control panel will restore the unit to its normal operating mode. If your pump and filter system is working normally and there are no flow restrictions and the heat pump continues to display “HP” or “HP3”, please call AquaPRO® Systems to arrange service for the heat pump. Please note, AquaPRO® Systems will not be responsible for non-warranted service calls.
MODELS: PRO1300h/c and
PRO1300h/c TCE
COL: This code reminds you that the unit is running in the cooling mode.
HOT: This means the pool temperature has increased by 2° while the unit is operating in the “COL” mode. This is only a warning that the unit is having difficulty cooling the pool to the desired temperature. The “HOT” message will remain until either the pool drops to the desired temperature or the set “COL” temperature is raised above the pool’s current temperature.
