Faqs

How do I correctly install and set up my dvt Swimming Pool Heat Pump for the first time?

To install your dvt Swimming Pool Heat Pump, place it on a flat, stable concrete base near existing plumbing, downstream of the filter and pump but upstream of chlorinators. Connect the unit using the correct pipe size (typically 1.5", 2", or 50mm) and secure electrical wiring with a dedicated circuit breaker, ensuring black connects to L1 and white to L2. Before powering on, open the bypass valve fully, run the filter pump to check for leaks, purge air from the system, and then turn on the electrical supply. Allow the unit to run 24 hours daily until the desired temperature is reached.

What should I do if my dvt Swimming Pool Heat Pump is not heating the water or showing an error?

If your dvt Swimming Pool Heat Pump is not heating, first verify that the filter pump is running, as the heat pump only operates when water flows. Check that the bypass valve is adjusted correctly; partially closing it may be needed to achieve the lowest flow rate without triggering an error. Ensure the water circuit is primed with no air inside the tubes. If the unit still fails, inspect the electrical connections for tightness and proper grounding, and confirm the ambient air temperature is between +10°C and +35°C, as extreme cold can prevent operation.
