Checks to electrical devices Repair and maintenance to electrical components shall include initial safety checks and compo- nent inspection procedures. If a fault exists that could compromise safety, then no electrical supply shall be connected to the circuit until it is satisfactorily dealt with. If the fault cannot be corrected immediately but it is necessary to continue operation, an adequate temporary solution shall be used.

Cabling Check that cabling will not be subject to wear, corrosion, excessive pressure, vibration, sharp ed- ges or any other adverse environmental effects. The check shall also take into account the effects of aging or continual vibration from sources such as compressors or fans. Detection of flammable refrigerants Under no circumstances shall potential sources of ignition be used in the searching for or detec- tion of refrigerant leaks.
Page 11
For appliances containing flammable refrigerants, refrigerants purging shall be achieved by brea- king the vacuum in the system with oxygen-free nitrogen and continuing to fill until the working pressure is achieved, then venting to atmosphere, and finally pulling down to a vacuum. This process shall be repeated until no refrigerant is within the system.
Page 12
Decommissioning Before carrying out this procedure, it is essential that the technician is completely familiar with the equipment and all its detail. It is recommended good practice that all refrigerants are recovered safely. Prior to the task being carried out, an oil and refrigerant sample shall be taken in case analysis is required prior to re-use of recovered refrigerant.
Page 13
Labelling Equipment shall be labelled stating that it has been de-commissioned and emptied of refrigerant. The label shall be dated and signed. For appliances containing FLAMMABLE REFRIGERANTS, ensure that there are labels on the equipment stating the equipment contains FLAMMABLE RE- FRIGERANT.

12. The evaporator fins must not be damaged. 13. This heat pump is not intended for use by persons with reduced physical, sensory or mental capabilities, or lack of experience and knowledge, unless they have been given supervision or instruction concerning use of the heat pump by a person responsible for their safety. 14.
6.3 Preparing the heat pump for use 6.3.1 Typical set-up The manufacturer provides the heat pump and water connection kit. Other parts, including a contingent by-pass must be provided by the user or installer. The heat pump should be located 7.5m (recommended) away from the swimming pool.
6.3.2 Required installation space A free area around the heat pump has to be kept clear from any object to get fresh air across the evaporator. 500 mm 1500 mm 1500 mm Blow-out Air Intake 500 mm The unit may be installed virtually anywhere outdoors. For indoor pools please consult the supplier. DO NOT place the unit in an enclosed area with a limited air volume, where the units discharge air will be re-circulated.
6.3.5 Installation of the piping The piping to and from the heat pump need to fit the chosen connections. The pipes can be glued, onto these water connections and can be made out off hard or flexible PVC. Always install piping intended for swimming pool use and use the correct glue to put them together.

Notes: - Depending on the starting temperature of the pool water and the air temperature, it can take several days for the water to reach the desired temperature. Covering the pool can drastically reduce this period. - The unit is equipped with a flow switch that is switched on when enough water is flowing in the unit and that is switched off when the water flow becomes too low (e.g.
7.6 Firmware update The firmware of the heatpump will be updated automatically using the app on first use. Be aware of 7.7.1 Heat loss The longer the distance from the pool, the greater the heat loss from the tubing. It is therefore recommended to place the pump as close to the pool as possible A good pool cover and insulation of the tubing to and from the swimming pool and heat pump can reduce the warming up time considerably.
7.7.3 Time delay of compressor The heat pump is equipped with a 3 minute built-in delay once the compressor is turned off and a 3 minute built-in compressor running time. Both to protect control circuit components, to eliminate restart cycling.This time delay will automatically restart the unit approximately 3 minutes after each electrical interruption.

8. Protection systems DURA Hi heat pumps are equipped with the following standard protection systems: 8.1 High exhaust temperature protection this protection protects the compressor and the overall system by preventing it from operating under conditions that could lead to overheating, damage, or failure. excessive heat can damage the compressor windings, bearings, or seals, leading to costly repairs or replacement.
8.5 Winter pipeline anti-freeze protection The winter pipeline anti-freeze protection mechanism primarily safeguards against: 1.Freezing and bursting of water pipes. 2.Damage to the water pump and compressor due to freezing or operation under unsafe conditions. 3.Operational disruptions caused by ice blockages or insufficient heat transfer. This protection ensures system longevity, prevents costly repairs, and maintains reliability during cold weather conditions.
8.9 Abnormal reversing of four-way valve The abnormal reversing of the four-way valve protection is designed to detect and prevent issues with the operation of the four-way valve, which is a critical component in a heat pump system. The four-way valve is responsible for switching between heating and cooling modes by reversing the flow of refrigerant.
8.12 Excessive temperature difference between inlet and outlet water protection The excessive temperature difference between inlet and outlet water protection is designed to sa- feguard the heat pump and its components from potential damage due to abnormal temperature differentials in the system. This protection monitors the difference between the water temperature entering and exiting the heat pump.
9. Maintenance and inspection - 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 as shown in section 5.3.
9.2 Winterizing Winterizing option 1 - Indoor storage We recommend storing DURA-Hi heat pumps in a garage or shed for winter. Perform the following actions to completely drain the heat pump: - Turn off the electrical power to the heat pump at the main breaker panel.
