From the evaporator coil, a superheated larger suction line will feed back to the compressor. Rio Bravo, Inc. 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. Service by unauthorized personnel will void the. A qualified technician should replace the air sensor. Same thing. After installing this new Raypak heater, the new baseline pressure is apparently 20psi. IO Igniter open error If the control is not in lockout and senses that the igniter circuit is open when the blower is running the control will turn off the blower and go into lockout. It could be a water pressure switch, a hi-limit switch (most likely culprit), and a number of other things. Outside air temp. Inspect your heat exchanger for chemical or sanitizer damage. Its a good idea to approach leak detection with a plan, including starting high on the coil and moving down (because refrigerant is heavier than air and may set off the leak detector below the actual leak).
