What to do if my Bosch LV070 Heat Pump compressor isn't running and the fan is on, but I suspect low refrigerant?
If your Bosch Heat Pump's compressor isn't running but the fan is, it could be due to a low-pressure fault caused by low refrigerant. Check the refrigerant pressure with a gauge set.
How to reduce objectionable noise levels from my Bosch LV070?
If you're experiencing objectionable noise levels from your Bosch Heat Pump, ensure the duct work and grilles are properly sized for unit air flow. If the fan speed setting is too high, consult the blower performance table and reduce fan speed if possible. To address structure borne noise, mount the unit on a vibration pad.
