3. Setup and Installation
Proper installation is crucial for the optimal performance and longevity of your heat pump. Refer to the detailed installation guide provided with your product for specific instructions.
Placement:
The heat pump should be placed on a solid, level surface, ideally outdoors, with sufficient clearance around it for proper airflow. Avoid enclosed spaces or areas with poor ventilation. The unit dimensions are approximately 45.8 x 47.2 x 53 cm (L x W x H).
Electrical Connection:
Connect the heat pump to a dedicated electrical circuit as specified in the electrical requirements section of the full manual. Ensure all connections are secure and waterproof.
