- User Interface: The heat pump features a digital display with buttons for ON/OFF, Unlock/Mode Selection, Speed (Smart/Silence), and Up/Down for temperature adjustment.
- Screen Lock: The screen automatically locks after 30 seconds of inactivity. Pressing the unlock button for 3 seconds unlocks it.
- Temperature Setting: Adjustable temperature ranges for Auto (12~35°C), Heating (18~35°C), and Cooling (12~30°C).
- Defrosting: Includes both auto defrosting (indicated by a flashing sun icon) and compulsory defrosting, which can be initiated manually.
- Safety Reminders:
- Always ensure the water pump is on before the heat pump and off after the heat pump for extended service life.
- Do not lift the water union when moving the heat pump to prevent damage to the titanium heat exchanger.
- Keep air inlet and outlet clear of obstacles for optimal efficiency.
- Avoid using or storing combustible gases or liquids near the unit.
- In case of abnormal operation (noises, smells, smoke, leakage), immediately cut off power and contact a dealer.
- The main power switch should be out of children's reach.
- Cut off power during lightning storms.
- Error Codes: The manual lists various error codes (E1-E8, EA, P0-P9, F1-F9, FA) to help diagnose issues such as high/low pressure, water flow problems, sensor failures, and compressor/inverter board issues. It also clarifies that certain codes (E3, Ed, Eb, E6, E5) are not failures but rather indicators of normal operating conditions (no water flow, anti-freezing, out of operating range, insufficient water flow, power abnormal).
Maintenance Features
- Daily Maintenance:
- Always cut off power before maintenance.
- Clean the evaporator with household detergents or clean water; never use gasoline, thinners, or similar fuels.
- Regularly check bolts, cables, and connections.
- Winterizing:
- During the winter season when the pool is not in use, cut off the power supply and drain all water from the heat pump.
- If the heat pump is used below 2°C, ensure continuous water flow to prevent freezing and potential damage to the titanium heat exchanger.
- Professional Maintenance:
- Installation, removal, and maintenance must be performed by professional personnel.
- Gas leakage tests are required before and after installation.
- Vacuum completely before welding; field welding is not allowed and must be done by professional personnel in a maintenance center.
- If gas leakage occurs, stop installation and return the unit to a professional maintenance center.
- All operators handling gas must be qualified by valid certification.
- Strictly follow manufacturer's requirements for maintenance and gas filling.
- Annual maintenance by a qualified professional technician is recommended. Do not touch electronic components until LED indication lights on the PCB turn off.
- Troubleshooting: A table is provided for common faults, their reasons, and solutions, such as "Heat pump doesn't run" (check power, switch, fuse, breaker) or "Fan running but with insufficient heating" (check evaporator/air outlet blockage, wait for start delay, adjust set temp). Users are advised not to attempt repairs themselves.
Installation Features
- Transportation: The heat pump must be stored and moved in an upright position. Sealing is not allowed during transportation. Goods should be transported at a constant speed to avoid sudden movements. The unit must be kept away from fire sources, and storage areas should be bright, wide, open, and well-ventilated with required ventilation equipment.
- Location: Must be installed in a well-ventilated, outdoor environment, not in a closed or indoor space. Keep away from fire sources.
- Piping:
- The inlet and outlet water unions cannot bear the weight of soft pipes; hard pipes must be used.
- To ensure heating efficiency, the water pipe length between the pool and the heat pump should be ≤10m.
- Minimum distances for installation are specified: 700mm from the front, 500mm from the side, and 700mm from the back, with 2500mm from the top.
- Mounting: The frame must be fixed to a solid concrete foundation or strong, anti-rust treated brackets using M10 bolts.
- Condensation Water: The unit discharges condensation water from the bottom; a drainage tube (accessory) should be inserted and connected to a pipe for proper drainage.
- Electrical Wiring:
- Must be connected to an appropriate power supply matching the product's rated voltage.
- The heat pump must be well-earthed.
- Wiring must be done by a professional technician according to the circuit diagram.
- A breaker or fuse (leakage operating current ≤ 30mA) must be set according to local codes.
- Power and signal cables should be laid out orderly without affecting each other.
- Detailed wiring diagrams are provided for 230V/1Ph/50Hz and 400V/3Ph/50Hz power supplies, including connections for the water pump and optional heating priority functions.
- Trial After Installation:
- Before startup, all wirings must be carefully checked.
- Inspect the entire installation, pipe connections, and electrical wiring.
- Ensure the main power is well connected and no obstacles are in front of air inlet/outlet.
- It is recommended to start the water pump before the heat pump and turn off the heat pump before the water pump for longer life.
- The heat pump has a start delay function (fan starts in 3 minutes, compressor in another 30 seconds) to protect the unit.
- Check for abnormal noise and verify temperature settings after startup.
