Need help?Do you have a question about the Hayward S.Line Pro Fi 25kW and is the answer not in the manual?
This document is an installation and operation manual for the Hayward S-LINE HEAT PUMP RANGE, designed for heating swimming pool water and maintaining a constant temperature.
The Hayward S-LINE Heat Pump Unit is designed to heat swimming pool water and maintain a constant temperature. It features a durable heat exchanger made of PVC and Titanium, which can withstand prolonged exposure to swimming pool water. The unit offers installation flexibility, as it can be installed outdoors. For indoor pools, consultation with the supplier is recommended. It operates quietly due to an efficient rotary/scroll compressor and a low-noise fan motor. The unit incorporates micro-computer controlling, allowing all operation parameters to be set and displayed on an LCD wire controller and the Aqua Temp App.
The heat pump operates by circulating water through its heat exchanger. The filter pump must be running to facilitate this circulation. Upon initial startup, users are instructed to open the valve, charge water, ensure the pump and water-in pipe are filled, close the valve, and then start the unit. The water-in pipe must be higher than the pool surface. After a few minutes of operation, the air leaving the top (or side) of the unit should be cooler (between 5-10℃). The unit is designed to run 24 hours a day until the desired pool water temperature is reached. Once the set temperature is achieved, the unit will slow down and turn off after 45 minutes if the temperature is maintained. It will automatically restart when the pool temperature drops more than 0.2℃ below the set temperature. A built-in 3-minute solid-state restart delay protects control circuit components and prevents rapid cycling.
The unit supports various operation modes, including heating, cooling (if applicable), and automatic mode. Temperature settings can be adjusted via the wire controller. It also includes clock setting features for system time and timing for mute and on/off functions. The wire controller has a keyboard lock feature to prevent misoperation. In case of a fault, the interface displays a fault code and serial number, and the manual provides a parameter list and breakdown table for troubleshooting. The unit can be connected to a WIFI module, allowing for remote control and monitoring via the Aqua Temp App.
The S-LINE Heat Pump Range uses R32 refrigerant. Power Supply: 220-240V~/50Hz for single-phase models, and 380-415V/3N~50Hz for three-phase models. Operating Range:
The S-LINE Heat Pump is designed for user-friendly operation. The LCD wire controller provides a clear interface for monitoring and controlling the unit. Interface Display: Shows current temperature (OUT/IN), set temperature, operating mode (heating, cooling, automatic), time, and various icons indicating status (e.g., compressor running, water pump running, fan running, mute, timing, locking, fault, wireless signal, Bluetooth, temperature units). Key Functions:
Regular maintenance is crucial for the unit's performance and longevity. Water System Checks: Regularly check the water supply device and release. Prevent air from entering the system and regularly clean the pool/spa filter to avoid damage from dirty or clogged filters. Unit Environment: Keep the area around the unit dry, clean, and well-ventilated. Clean the side heating exchanger regularly to maintain good heat exchange efficiency. Refrigerant System: The refrigerant system should only be serviced by a certified technician. Electrical Checks: Frequently inspect power supply and cable connections. If abnormal operation occurs, switch off the unit and contact a qualified technician. Winterization: Discharge all water from the water pump and water system to prevent freezing if the unit will not be used for an extended period. Thoroughly check and refill the system before using it after prolonged non-usage. Flammable Refrigerant Safety: Strict safety checks are required when working on systems containing flammable refrigerants (R32). This includes ensuring no ignition sources are present, working in a well-ventilated area, checking for refrigerant leaks with appropriate detectors, and having fire extinguishing equipment readily available. Component Integrity: Ensure electrical components are fit for purpose and specification. Follow manufacturer's maintenance guidelines. Check that the charge size is in accordance with the room size, ventilation is adequate, and refrigerant pipes/components are protected from corrosion. Electrical Device Maintenance: Repairs to electrical components must include initial safety checks. Ensure capacitors are discharged, no live electrical components are exposed, and earth bonding continuity is maintained. Refrigerant Recovery and Charging: Follow controlled procedures for removing and charging refrigerant to minimize risks. Use appropriate recovery cylinders, ensure proper labeling, and purge the system with oxygen-free nitrogen (OFN) during brazing processes. Do not overfill cylinders. Safety Wire: The safety wire model is 5*20_5A/250VAC and must meet explosion-proof requirements.
