Installation instruction & Operation Points

Cautions of Installation：

1. Any chemicals must be guaranteed to be added to the pipes after the heat pump (ie, the chemicals cannot enter the heat pump).
2. When placing or transporting the equipment, it should be placed upwards and kept upright, and must not be dumped or inverted.

Installation Locations

The product can be installed and used at any predetermined location as long as the following three conditions are met:

1. Good ventilation
2. Stable power supply
3. Pool filter

This heat pump should be installed in a well-ventilated place outside, and the distance from the swimming pool should be greater than or equal to 2 meters. The machine outlet should be at least 1 meter away from the obstacles, and the surrounding obstacles should be at least 0.5 meters. If installed indoors, please consult the installer to keep the room well ventilated.

Note: Do not install the unit in a confined or insufficient ventilation location, or in a location where it may block the air intake. These locations can affect the flow air c. It will cause the air to recirculate, resulting in reduced efficiency. It even may stop the system from running.

Trial

Note: Please ensure the order of “When start, start water pump before heat pump, When finish, turn off heat pump before water pump”, otherwise it will damage the heat pump.

Connection

  Power Supply

Before connecting the power supply, make sure that the power supply matches the rated power supply of the product.

Breaker

| Residual-current circuit breaker| 4.5| 8.0| 9
Rated residual leakage current| 30| 30| 30
Fuse| 4.5| 8.0| 9

Note: The above data is adapted to power cord ≤ 10m. If power cord is＞10m, wire diameter  must be increased. The signal cable can be extended to 50m at most.

Pay attention:

After all connections are complete and checked, perform the following steps:

1.  The user should start the water pump first to ensure no water leakage in the water pipe system; then set the thermostat at the appropriate temperature after power on.
2. In order to protect the machine, it has a delayed start function, after start up, the water pump start, next fan runs, and the compressor will start up automatically after about 3 minutes
3.  Check if there is any abnormal noise when running
4. Check that the set temperature is appropriate

Depending on the initial temperature of the pool water and the air temperature, it may take several days to heat the water to the desired temperature. A good swimming pool cover can greatly reduce the time required.

Time delay – the heat pump has a built built-in 3 3-minute start delay (only started when heated) to
protect th e circuit and avoid frequent switches causing losses. The machine will restart
automatically after the delay period. Even a brief power outage can trigger this delay and
prevent the machine from restarting immediately. Power on and off during this delay do es not
affect the 3 3-minute duration of the delay.

Condensate water

The air entering the heat pump is strongly cooled when heat pump heat the pool water, which may cause condensation of the evaporator fins. At higher relative humidity, condensation can reach several litters per hour. This phenomenon is sometimes mistaken for a leak.

Failure code

Daily Maintenance and Product Repair

1. Daily maintenance
2. Properly set the temperature and humidity for a cozy environment, avoid overheating or excessive cooling.
3.  Don’t put obstacles before the air inlet and outlet of the heat pump, or the efficiency of the heat pump will be reduced, even heat pump stopped.
4.  Don’t put your hand or the stick into inlet or outlet, do not remove the fan mesh, otherwise the running fan might cause damage to you.
5.  Don’t use or store combustible gas or liquid such as thinners, paint and fuel to avoid fire.
