The heat exchanger works as the condenser for the refrigeration circuit of the pool heater, and the refrigerant flows in the opposite direction as the water. This heat gets passed off into the water through the heat exchanger inside the pool heater. Corrective Action:Check the capacitor and fan motor. 2012 - R.P.M of fan coil blower too low. Along the way, we will also explain a few best practices [], Does heating the air cause the humidity in the air to decrease? 2. CLEAN YOUR POOL FILTER. Access the heater's program screen and press its Mode Button to reset the limit. It may not display this or other websites correctly. b. In my opinion, the tubing diameter needs to be twice as big. An ultrasonic leak detector picks up the sound of refrigerant and air leaking out of a hole to pinpoint the leak. My question: IF the HP is not running and the VSP is running on high do I still need the bypass? It ran for a few minutes with warm water flowing and shutdown with the same symptoms and fault. Suction leak allowing air into the water flow. Low water flow when switched t. Corrective Action: Verify water pump is on. If possible, replace the motor with a larger one. Call your dealer for advice. Increasing pressure goes hand in hand with the decrease of water flow. One side of the system is considered the high pressure side and the other side is considered the low pressure side. Repairs to the refrigerant circuit must not be attempted by untrained or unqualified individuals. Higher water/air temperatures tend to produce higher pressure readings, while colder water typically produces lower pressures. HVAC systems, regardless of size, are designed to move a certain amount of air. The heater only comes on if its turned all the way up. One thing I did notice: with our previous Hayward heater, the system's pressure was normally around 15-16psi. Hello , This is an inactive thread. This goes on and on until the heater finally meets its set temperature. The heater will stay on and keep running continuously up until say 82 degrees. When problem started happening last early last year, one of the thing I did was replaced a broken Jandy check valve between the heater and chlorinator. Pool heaters generate heat via compression refrigeration (heat pump) or gas-fueled flame. If the refrigerant flows in a different direction, it causes a switch in the function of the indoor and outdoor coils, and it changes whether heat leaves or enters your home. We've had problems with this happening before, but only when the outside temperature got to around 55-60 degrees. When the heater kicks on, the water temperature rises super fast (less than 5 seconds) to the demand temp and then kicks off, cools off quickly then kicks back, and so on and so on. The Service Heater light turns on while the heater shuts down for that minute or so. Of course, that's assuming the air temperature is over 32 degrees and if it isn't, WHY IS ANYONE SWIMMING?! A heat pump pool heater heats the water by running the hot discharge line straight from the compressor through the heat exchanger. Do not exceed maximum flow rate for your model. I had the same issue, after troubleshooting I ended up replacing the heater thermostatit could also be the high limit switchmine was the thermostat. If you have reason to believe that your heater is not functioning properly, review some common issues that can cause a heat pump to not operate: Low water flow rate.This is the number one issue for the heat pump not working. It is being practiced by thousands of pool owners just like you. If. Determine if an insufficient amount of air is being supplied to the equipment. Check resistance of switch, if open, replace switch. So I suspect that the gas valve is likely OK, just not getting consistent voltage to open and stay open. My front display board doesnt go on at all. High ambient temperature. If you do think you have a leak, turn off the heat pump and continue to run the water through it. Corrective Action: Verify water circulation pump is on. There could be a defect in the heat exchanger caused by the manufacturing process or imbalanced water chemistry. Sometimes it may take a bit of time to find the right fit. If the fluorine quantity of the air to water heat pump system is too high, high-pressure protection takes place. A qualified technician should replace the battery. The compressor does not engage, just the fan. It is being practiced by thousands of pool owners just like you. A qualified technician should replace the water sensor. Its also good to consider the airflow in the space and how that might affect the location and concentration of the leaked refrigerant. Now in spring Im trying to get it to fire, but nothing. Both situations are very common. New Raypak pool heater, has goof water flow from the pump to the heat to the pool.

Minimum flow 30 GPM. That is what created the Grand Canyon. Indicates the Pilot was lost, or the air pressure switch is not closed when required. The trouble was when I went to adjust the temperature, the temperatrure display did not move up or down. Like most units of measure, it has a very simple origin; in a water manometer, 1 of water column is literally the amount of force it takes to raise the column of water by 1. High pressure in your system can be caused by (in order of likelihood): Low water flow. 2012 - For a pool your size, you will need a higher BTU size. Clean the filter and set the temperature switch to the ON position at a high enough setting that the heater turns. Check resistance of switch with a full charge, if open, replace switch. Low condenser airflow will show up as high head pressure, normal . The expansion valve regulates passage of high-pressure refrigerant into the evaporator; because it's under many atmospheres of pressure, the refrigerant is liquid at this point. Therefore the pump must be operating for an accurate pool or spa water temperature to be displayed. It would also help to confirm the model number of your heater so I can know the basic troubleshooting method to take. Check for correct incoming power at fan relay- 120V or 240V and at fan motor.

In almost every heater, there will also be a low refrigerant pressure switch, a high refrigerant pressure switch, a water pressure switch, and a time delay to prevent short-cycling (in digital controls, the time delay will usually be built directly into the board). Improper plumbing valve settings. Incoming water temperature has exceeded 110 F (43 C) and the unit has been deactivated. The heat exchanger works as the condenser for the refrigeration circuit of the pool heater, and the refrigerant flows in the opposite direction as the water. It will turn on and turn back off after about 45 seconds. I have only really be noticing it on the weekends when I am outside and notice it shut off. Venturi air inlets are open.

Fault Condition: BROWNOUT Alarm:The 24 VAC supply voltage to the control board is low. Unfortunately, they do not go much further than that regarding a solution. Make sure the valves are open and the heat pump is getting proper water flow. Clean entire filtering system and or replace filter element. If this does not correct problem, call for service. Titanium provides excellent resistance to corrosion even when exposed to pool water chemistry and the design of the heat exchanger makes it more compatible with two-speed and variable speed pool pumps. Heat exchanger clogged with debris. Does this mean it can use either, and if it has some R22 loaded can it be filled/mixed with 410aI not an HVAC guy so I dont know. If the issue reoccurs, please see "Contacting AquaCalAutoPilot, Inc." on page 1. In some cases, we also have to watch for automatic zeroing capabilities.
