This document is an owner's manual and safety instructions for a Swimming Pool Heat Pump, model number 75217, manufactured by XtremePowerUS. It provides essential information for the safe installation, operation, and maintenance of the device.
Function Description:
The Swimming Pool Heat Pump Unit is designed to heat swimming pool water and regulate its temperature. It operates by extracting heat from the ambient air and transferring it to the pool water, offering an energy-efficient method for pool heating. The unit is intended for outdoor installation and requires proper clearances for optimal air intake and discharge. It features a control panel for setting desired water temperatures and monitoring various operational parameters. The system includes safety features such as high and low-pressure switches, water flow detection, and anti-frost protection to ensure safe and reliable operation.

Usage Features:
The heat pump offers several operational modes including Cooling, Heating, and Auto mode. Users can set the desired water temperature within a range of 50-113°F (10-45°C) for both heating and cooling. The unit's display panel shows real-time temperature readings (inlet, ambient, coil, return gas, compressor, water inlet), operational status, and error codes.
Key operational settings include:
- Cooling/Heating setting water temperature: 50-113°F (default 79°F)
- Turnaround of defrosting under heat mode: 30-90 min (default 45 min)
- Defrosting start temperature: 32-86°F (default 19°F)
- Defrost exit temperature: 30-86°F (default 56°F)
- Time of exit defrost under heat mode: 1-12 min (default 5 min)
- Mode (cool/cool & heat/E-heat/heat): 0/1/2/3 (default 1)
- EEV manual/automatic: 0/1 (default 1)
- Heating Target Superheat: 5-59°F (default 34°F)
- Cooling Target Superheat: 5-59°F (default 25°F)
- Auto mode setting water temperature: 50-113°F (default 79°F)
- Compressor protection Exhaust temperature: 185-230°F (default 203°F)
- Low ambient temperature protection: -4-50°F (default 5°F)
- EEV manual step number: 18-94 (default 70)
The unit features a time delay starting function (blower runs for 3 minutes before the compressor starts) to protect the system. It also includes a real-time clock and timer function for programming start and stop times. A key lock feature prevents accidental changes to settings.
Maintenance Features:
Regular maintenance is crucial for the longevity and efficiency of the heat pump.
- Pre-use Inspection: Before operation, verify the installation of the machine and pipe connections, electrical wiring, proper bonding, and temperature settings. Ensure air inlet and outlet are clear.
- Cleaning: The unit should be cleaned with household detergents or clean water, avoiding gasoline or thinners. The area around the unit must be kept dry, clean, and well-ventilated. The side heating exchanger (evaporator coil) should be cleaned regularly with a non-pressurized water spray to remove dirt and maintain good heat exchange. The plastic cabinet can be cleaned with a brush and soap.
- Winterization: During winter or extended periods of non-use, the unit must be drained of all water by disconnecting the IN and OUT water connections and tilting or blowing out the unit with air. The power supply should be disconnected, and the machine covered with a plastic cover to protect it from dust.
- Troubleshooting: The manual provides a troubleshooting guide for common faults such as "Main power is off," "Switch off," "Burnt out fuse," "Circuit breaker drops out," "Blocked air inlet/outlet," "3 minutes time lag protection," and "Temperature set too low." It also lists error codes (E20, E10, E09, E12, E04, E25, E14, PP9, E05, E06, E03, PEE, E07, E08, PE2) related to defective regulating components, along with their causes and solutions.
- Professional Assistance: For abnormal noises, odors, smoke, electricity leakage, or unresolved faults, users are advised to switch off power immediately and contact a qualified technician or local dealer for repairs. All electrical connections and repairs must be performed by qualified electricians according to national and local codes.
