Wellis Inverter Spa Heat Pump
PLEASE READ IT CAREFULLY AND KEEP IT FOR SUBSEQUENT USE. This manual provides you the necessary information for optimal use and maintenance
Product Information
The heat pump is designed to heat pool water within a specific temperature range. It has two modes: Smart and Silence. Smart mode allows for fast heating with 20% to 100% heating capacity optimization, while Silence mode lowers the sound level by 3dB(A) and operates at 20% to 80% heating capacity. The heat pump has a Power-off memory function and automatically restarts when power is recovered. It is important to note that the heat pump can only be used to heat pool water and should never be used to heat flammable or turbid liquids. Moving the heat pump while lifting the water union can cause damage to the titanium heat exchanger inside.
Product Usage Instructions
Before using the heat pump, it is important to ensure that all components are present as per the list provided in the user manual. The operating range for air temperature is between -7°C to 43°C for heating. The ideal operating range for air temperature is between 15°C to 25°C for heating. The heat pump should be installed or removed by professionals and should not be dismantled or refitted without permission. Obstacles should not be placed in front of the air inlet and outlet of the heat pump. The installation must be kept away from any source of fire and must be well-ventilated with no closed environment or indoor installation allowed.
Transportation of the heat pump should avoid sudden acceleration or sudden braking to reduce collision with goods.
