EU heat pumps 3. Installation and connection 3.1 Remarks The factory only provides the heat pump unit; the other parts, including a contingent by-pass, are to be provided by the user or the installer. Attention: Please take the following steps when installing the heat pump: 1. Each addition of chemicals has to be performed through the conduits located downstream of the heat pump. 2.
EU heat pumps 3.3 Distance from the pool Normally, the pool heat pump is installed within a 7.5 meter radius of the pool. The greater the distance from the pool, the greater the heat loss from the piping. Since the piping is buried for the most part, heat loss is minimal for distances of up to 30 meters (15 meters to and from the pump = 30 meters total), unless the soil is wet or the water level is high. Heat loss per 30 meters could roughly be estimated at 0.
EU heat pumps 3.5 Typical setup Note – This setup is just an example 3.6 Adjusting the by-pass F R O M T O P O O L P O O L Uit Adjust the by-pass as follows: • open the 3 valves completely • slightly close valve 1 until water pressure has increased with approximately 100 to 200 grams (see also 3.8) • close valve 3 about halfway to adjust the pressure of the refrigerant gas in the unit. In Heat pump Optimum heat pump operation is reached when the refrigerant gas reaches a pressure of 30 +/- 2 bar.
EU heat pumps 3.7 Electrical hook-up Important - Although the heat pump is electrically isolated from the rest of the unit, this only prevents the passage of electricity to or from the pool water. Grounding the unit is still required to protect yourself from short circuits inside the unit. Make for adequate ground connection. Check if the electrical mains voltage corresponds with the operating voltage of the heat pump prior to hooking up the unit.
EU heat pumps 3.8 First time start-up Note - In order for the unit to heat the pool (or spa), the filter pump must be running so that the water can circulate through the heat pump. Without this circulation, the heat pump will not start. When all connections have been made and checked, you should follow these steps: 1. Turn on the filter pump. Check for leaks and verify flow to and from the pool. 2.
EU heat pumps 4. Use and operation 4.1 Features of the LED control panel LED screen Press “ or ” to modify settings Press “MODE” to set the operating mode On/Off Set start time Access to parameters Set stop time Press “CLOCK” to set the time With the “On/Off” key “ “, the heat pump is turned on or turned off (stand-by status). If the LED next to this key lights up, the heat pump is turned ON.
EU heat pumps The first number on the LED screen stands for the number of the parameter and the second one for its value.
EU heat pumps Parameter 10 sets the desired operation mode for the fan speed. Value for parameter 10 Fan control Low fan speed High fan speed Automatic fan speed (high speed when air temperature is below 10°C, low speed when higher than 15°C) Low fan speed between 9PM and 8AM, high speed at other time Automatic running according to a combination of value 2 and 3 Parameters are modified as follows: • • • • • • Set the heat pump in its STAND-BY mode. Press the service key “ to access the parameter menu.
EU heat pumps 4.4 Setting the CLOCK • • • • • Start setting the clock by pressing the “CLOCK” key. The LED screen will display the time and the hours will start to blink. Press “ or ” to set the desired hour. Press “CLOCK” again. Now, the minutes start blinking. Press “ or ” again to set the minutes. Press “CLOCK” again to save the settings. While setting the clock, the “TIMER ON” and “TIMER OFF” keys are inactive. 4.
EU heat pumps 5. Protection systems EU heat pumps are equipped with the following standard protection systems: 5.1 Water pressure switch Thanks to this pressure switch, the heat pump will not work when the filter pump is not working (and the water is not circulating). This system prevents the heat pump from heating only the water present in the heat pump itself. The protection also stops the heat pump if water circulation is cut off or stopped. 5.
EU heat pumps 5.7 Anti-frost protection during winter This protection can only be activated if the heat pump is in STAND-BY mode. 5.7.1 First anti-frost protection If the filter pump is controlled by the heat pump (regardless of the value for parameter 9) and when the water temperature lies between 2 and 4 °C and the air temperature is lower than 0 °C, the filter pump will be automatically turned on to prevent the water from freezing in the piping.
EU heat pumps 6. Directions 6.1 Swimming pool water chemistry Special attention should be paid to the chemical balance of the pool water. The pool water values should always stay within the following limits: pH Free chlorine (mg/l) TAC (mg/l) Salt (g/l) Min. 7.0 0.5 80 Max. 7.8 1.2 150 8 Important: failure to comply with these limits will invalidate the warranty. Note: exceeding one or several limits can damage the heat pump beyond repair.
EU heat pumps 6.3 Heat pump winterizing Important: failure to take the necessary precautions for winterizing can damage the heat pump, which will invalidate the warranty. The heat pump, filter pump, filter and conduits must be protected in areas where the temperature can drop below the freezing point. Evacuate all water from the heat pump as follows: 1. interrupt the electrical power supply to the heat pump 2. close the water supply to the heat pump: completely close valves 2 and 3 of the by-pass 3.
EU heat pumps 7. Maintenance and inspection 7.1 Maintenance • • • • • • Check the water inlet and drainage often. The water and air inflow into the system should be sufficient so that its performance and reliability does not get compromised. You should clean the pool filter regularly to avoid damage to the unit caused by clogging of the filter. The area around the unit should be spacious and well ventilated. Clean the sides of the heat pump regularly to maintain good heat exchange and to save energy.
