1.1.2 WARNING WARNING 



Device, cables and accessories must be inspected before use to guarantee their normal and safe operation.







This equipment can only be connected to the socket with ground protection. Please adopt a rechargeable battery instead of the socket as the power supply if the socket is not provided with a ground lead.







To prevent fire or explosion, do not operate the equipment in the presence of anesthetic, flammable or explosive materials.







Do not open the equipment casing as there is the impending danger of electric shock. Equipment maintenance and upgrades must be carried out by maintenance technicians whom are trained and licensed by the manufacturer. Moreover, the process must be done only after the AC power supply is disconnected. Maintenance carried out by individuals non-affiliated to the manufacturer or by non-licensed personnel may affect the safety, performance and function of the product.







When used with electrosurgery equipment, the safety of patients should be ensured.







The patient's clinical condition and the working condition of the infusion pump must be monitored carefully, the alarm volume and alarm levels need to be set according to the actual needs. Operation and performance relying solely on the auditory alarm system alone is not sufficient, and setting the alarm at a low volume may endanger the patient. If the alarm volume is less than the surroundings volume, which can further lead to operators identify alarm mistakenly.







Please carefully install the power line and cables with various accessories to prevent the patient from choking or suffocation caused by entanglement of the cables or by electrical disturbance.







The packaging materials must be disposed of in compliance with local laws and regulations or the hospital policy on waste management.They must be kept out of the reach of children.







Infusion tube knots, filter coagulation and occlusions arising from needle insertion can cause the pressure inside the infusion tube to rise during infusion. When this occurs, removing the occlusion can cause 1-2



excessive liquid drug to be infused into the patient, so appropriate measures should be taken. 



The pump should not be placed more than 100 cm above or below the level of the patient’s heart. The smaller the height difference between the pump, the more accurate the pressure test in the infusion cannula will be.







This equipment has to be used with infusion tubes recommended by manufacturers, SK Medical is not responsible for its accuracy and alarm function with non-recommended infusion tubes.







Do not touch the patient when connecting the peripheral equipment via the input/output signal ports to prevent patient leakage current from exceeding the requirements specified by the standard.

Use the accessories specified in this Operator’s Manual to guarantee the patient’s safety.







When this infusion pump and its accessories exceed their service life, they must be disposed of in accordance with local statutes or hospital regulations. If you have any queries, please contact your distributor or the manufacturer.







After installation of the infusion tube and before infusion, check for leakages. If any are found, they should be rectified as soon as possible.







User should adjust the fixing site of the infusion tube every 4 hours after infusion begins, in order to guarantee its accuracy. We suggest to replace the infusion tube after the infusion has been running for 24 hours.







Electromagnetic fields may affect equipment performance. This makes it necessary for other equipment used in the vicinity of the pump to meet EMC standards. Mobile phones, X ray and MRI equipment are all potential interference sources because of their high-intensity electromagnetic radiation.







Before the equipment is connected to the power supply, check that the voltage and frequency of the power supply match the specifications on the label or in this Operator’s Manual.







Please install and carry the equipment correctly to protect the equipment from damage from drops, impacts, violent shaking or other 1-3



external mechanical forces. 
