Dealer Sales & Service Guide 1- 61 11 Check to make sure you do not have any bypass valve or any valving in incorrect position which is causing flow restriction Check pool filter pressure gauge -Rule of thumb Sand filter low than 25 psi, Cartridge filter lower than 15 psi , Earth Filter lower than 18 psi In Floor cleaning system valves not working properly Confirm that the indoor fan is operating and air is blowing out of the supply registers. Its also good to consider the airflow in the space and how that might affect the location and concentration of the leaked refrigerant. What is the full model number? 2023 Poolheatpumps.com. Insufficient supply voltage to the heat pump. 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).

You can buy one at any HVAC supply store. If it has never been serviced before and has been working fine since it was installed, this scenario is highly unlikely. What flow rate do you have going to the heat pump? Clogged filter pump impeller. Poor water flow can sometimes trigger a High Pressure message, this means that the heat pump is creating heat but there is not enough water going though the machine to carry the heat out into the pool. 2. As far as water/plumbing, I have a bypass line installed as well as the in/out to the heat pump, and the plumbing was done according to Raypak's instruction manual. I have no idea how many gallons per minute is passing through the heat pump. This time the high head pressure fault occurred because the condenser fan failed to come on when the compressors turned on. If a multiple-speed filter pump is being used, run at a higher speed to determine if the error persists. Put the cover of the control panel. Pool pump timer is not set for a long enough running period.
