This document is an installation and user manual for a Swimming Pool Heat Pump, specifically the Aqua Pro Systems™ brand. It provides comprehensive information for the proper installation, operation, and maintenance of the device.

The primary function of this heat pump is to efficiently and economically heat and cool swimming pool water, providing comfort and pleasure to the user. It is designed exclusively for swimming pool applications and should not be used for heating other liquid materials. The manual emphasizes that installation must be performed by a qualified electrician or pool professional, and end-users are not qualified to install the heater themselves to prevent damage or safety risks.

The manual notes that performance and parameters are subject to change for technical improvement without notice, and users should refer to the nameplate for the most current details. The product operates optimally within water temperatures of 80°F to 104°F and air temperatures of 32°F to 109°F; efficiency is not guaranteed outside this range.

Usage Features:

• Sensitive and Accurate Temperature Control: Allows for precise setting and display of water temperature.
• Safety Protections: Includes high pressure, low pressure, and exceeding low temperature auto-stop protection.
• Defrosting: Features temperature-controlled compulsory defrosting.
• Compressor: Utilizes an international brand compressor for reliability.
• Heat Exchanger: Equipped with a high-efficiency titanium heat exchanger.
• Ease of Use: Designed for easy installation and operation.
• Power-off Memory Function: Retains settings after a power interruption.
• Digital Display: The control panel features a digital display showing current temperature, operating mode, and timer settings.
• Operating Modes:
  • Power ON/OFF: Simple button press to turn the unit on or off.
  • Up/Down Buttons: Used to set the desired water temperature (range 65°F to 104°F).
  • Fan Button: Selects "Silence mode" for quieter operation.
  • Heating Mode: The unit primarily operates in heating mode.
  • Timer Function: Allows users to set specific ON/OFF times for the heat pump.
• Start-up Sequence: After turning on, the fan starts in 3 minutes, followed by the compressor in another 30 seconds.
• Compulsory Defrost: Can be manually initiated by pressing "M" and "Down" buttons simultaneously for 5 seconds when the compressor has been running continuously for 10 minutes in heating mode. There must be a break of at least 30 minutes between compulsory defrost cycles. The defrost symbol twinkles during this process.
• Error Codes: A comprehensive list of failure codes (E1-E8, P0-P9, F1-F9, Fb, FA) is provided to help diagnose issues, ranging from water protection failures to sensor malfunctions and compressor/inverter board errors.

Maintenance Features:

• Winterization: When not in use during winter, the power supply should be cut off, water drained from the heat exchanger (by unscrewing the inlet pipe nozzle), and the unit covered to prevent freezing damage to the titanium heat exchanger.
• Cleaning: The heater body should be cleaned with household detergents or clean water. Gasoline, thinners, or similar fuels must never be used.
• Regular Checks: Users are advised to regularly check bolts, cables, and connections.
• Professional Repair: In case of abnormal conditions (noise, smell, smoke, electrical leakage) or if troubleshooting steps fail, the main power should be switched off immediately, and a local dealer/installer contacted. Users are explicitly warned against attempting repairs themselves.
• Power Outage Protocol: If a power cut occurs during operation, the heater will automatically restart when power is restored. To prevent unintended operation, the main power supply should be switched off during a power cut, and the temperature reset upon power restoration.
• Lightning/Storm Protection: The main power supply should be switched off during lightning and storm weather to prevent damage.
• Long-term Storage: For extended periods of non-use, the power supply should be cut off, and water drained from the machine by opening the inlet pipe tap.

The manual also includes critical safety warnings, such as ensuring the main power switch is out of reach of children, not placing hands or objects in air inlets/outlets, and maintaining proper ventilation around the unit to avoid air recirculation and ensure optimal efficiency. Minimum clearance requirements (500mm around the circumference, 1000mm on the air outlet) are specified to prevent reduced efficiency or unit stoppage.
