What to do if the water pressure relief valve opens on my Daikin EWAQ005ACV3P Air Conditioner?
If the water pressure relief valve on your Daikin Air Conditioner is opening, it could be due to a broken expansion vessel or the water volume in the installation being too high. Replace the expansion vessel or reduce the water volume to be under the maximum allowed value.
How to fix a noisy (cavitation) Daikin Air Conditioner pump?
If your Daikin Air Conditioner pump is making noise (cavitation), it could be due to a broken expansion vessel or the water volume in the installation being too high. Consider these steps to resolve the issue: * Replace the expansion vessel. * Ensure the water volume in the installation is under the maximum allowed value.
What to do if the water pressure relief valve leaks in Daikin Air Conditioner?
If the water pressure relief valve is leaking in your Daikin Air Conditioner, check that the expansion vessel is not broken and verify that the setting of the pre-pressure of the expansion vessel is correct.
