An additional symbol is used to indicate a hazard that would be assigned a signal word "WARNING" or "CAUTION."
Following the symbol explanations, the manual outlines "EXCEPTION CLAUSES" which detail the circumstances under which the manufacturer will not bear responsibility for personal injury or property loss. These include damage due to improper use or misuse, alterations or maintenance without abiding by the instruction manual, defects caused by corrosive gas, improper operation during transportation, operation or maintenance without following instructions, problems caused by quality or performance of parts from other manufacturers, and damage due to natural calamities, bad environmental conditions, or force majeure.
The "CONFORMITY AND RANGE" section reiterates the importance of reading the manual carefully and using the air conditioner only as instructed. It clarifies that the instructions are not exhaustive for every possible condition and situation, emphasizing the need for common sense and caution in installation, operation, and maintenance, as with any electrical household appliance.
The "WARNING" section on operation and maintenance provides crucial safety guidelines. It states that the appliance can be used by children aged 8 and above, and persons with reduced physical, sensory, or mental capabilities, or lack of experience and knowledge, only if they have been given supervision or instruction on safe use and understand the associated hazards. Children should be supervised to prevent them from playing with the appliance, and cleaning and user maintenance should not be performed by children without supervision.
Further warnings include not connecting the air conditioner to a multi-purpose socket to avoid fire hazards, and always disconnecting the power supply before cleaning to prevent electric shock. If the supply cord is damaged, it must be replaced by the manufacturer, its service agent, or similarly qualified persons to avoid hazards. Users are cautioned against washing the air conditioner with water or spraying water on the indoor unit, as this can cause electric shock or malfunction. After removing the filter, users should avoid touching the fins to prevent injury. The manual also advises against using fire or a hair dryer to dry the filter, as this could cause deformation or fire hazards. Maintenance must be performed by qualified professionals to prevent personal injury or damage, and users should not attempt to repair the air conditioner themselves, but rather contact the dealer for repairs. Extending fingers or objects into the air inlet or outlet is prohibited to prevent personal injury or damage. Blocking the air outlet or inlet can cause malfunction. Spilling water on the remote controller can damage it.
In cases of abnormal phenomena such as an overheating or damaged power cord, abnormal sounds, frequent circuit breaker trips, burning smell, or indoor unit leakage, users are instructed to immediately turn off the air conditioner, disconnect power, and contact the dealer or qualified professionals for service. The manual also warns that operating the air conditioner under abnormal conditions can lead to malfunction, electric shock, or fire. When using the emergency operation switch, an insulating object (not metal) should be used. Users should not step on the outdoor unit or place heavy objects on it to prevent damage or personal injury.
The "Attachment" section focuses on installation requirements. It mandates that installation must be performed by qualified professionals to avoid personal injury or damage, and that electric safety regulations must be followed. Local safety regulations dictate the use of a qualified power supply circuit and circuit breaker. A circuit breaker must be installed to prevent malfunction. An all-pole disconnection switch with at least 3mm contact separation in all poles must be connected in fixed wiring. The circuit breaker should have suitable capacity and include magnet buckle and heating buckle functions to protect against circuit shorts and overloads. Proper grounding is essential to prevent electric shock, and unqualified power cords should not be used. The power supply must match the air conditioner's requirements, as unstable power or incorrect wiring can cause electric shock, fire, or malfunction. Proper power supply cables must be installed before using the air conditioner. Live, neutral, and grounding wires of the power socket must be connected correctly. Power supply must be cut off before any electrical work. Power should not be supplied before installation is complete. If the supply cord is damaged, it must be replaced by the manufacturer, its service agent, or similarly qualified persons. The temperature of the refrigerant circuit will be high, so the interconnection cable should be kept away from the copper tube. The appliance must be installed in accordance with national wiring regulations, and specifically with NEC and CEC requirements by authorized personnel only.
Further warnings regarding electrical safety include ensuring the air conditioner, being a first-class electric appliance, is properly grounded by a professional with a specialized grounding device to prevent electric shock. The yellow-green wire is designated as the grounding wire and should not be used for other purposes. Grounding resistance must comply with national electric safety regulations. The appliance must be positioned so that the plug is accessible. All wiring for indoor and outdoor units must be connected by a professional. If the power connection wire is insufficient, users should contact the supplier for a new one and avoid extending the wire themselves. For air conditioners with a plug, it must be reachable after installation. For units without a plug, a circuit breaker must be installed in the line. Relocation of the air conditioner should only be performed by qualified personnel to avoid personal injury or damage. The installation location should be out of reach for children and away from animals or plants; if unavoidable, a fence should be added for safety. The indoor unit should be installed close to the wall.
The "THE INSTRUCTIONS BEFORE USE" section provides a series of important instructions and warnings. If a burning smell or smoke is detected, the power supply must be turned off, and the service center contacted. Continued operation under such conditions can lead to damage, electric shock, or fire. The power supply must utilize a special circuit with an air switch for protection and adequate capacity. The unit's automatic on/off function should be relied upon, and frequent manual switching should be avoided to prevent adverse effects. Power cables and control wires should never be cut or damaged; if damaged, they must be replaced by a professional. Using unapproved or damaged electric wires is prohibited. The power supply should be disconnected if the air conditioner will be out of use for an extended period. Accumulated dust can cause overheating or fire. When cleaning, the unit must be stopped and the power supply turned off to prevent electric shock or damage. The rated voltage of the air conditioner (208/230V, 60Hz) is critical; low voltage can cause the compressor to vibrate sharply, damaging the refrigerating system and electrical components. Users should not attempt to repair the air conditioner themselves, as incorrect repairs can lead to electric shock or fire, necessitating contact with the service center. The installed stand must be firm enough to prevent the unit from falling and causing injury. Stepping on the outdoor unit or placing objects on it is dangerous. Finally, the unit must be reliably earthed, with the earthing cable connected to a special earthing device in the building.
The "NAME OF PARTS" section provides a diagram of the outdoor unit, identifying the air outlet grille and valve. It notes that these figures are simple diagrams and may not perfectly match the appearance of purchased units. The "OUTDOOR UNIT WORKING TEMPERATURE RANGE" table specifies the maximum cooling and heating temperatures for both indoor and outdoor sides. It also states that the operating temperature range (outdoor temperature) for cooling-only units is -30°C to 48°C, and for heat pump units is -30°C to 48°C.
The "ELECTRICAL CONNECTIONS" section details the wiring process for different models (KM18H5O, KM24H5O, KM30H5O, KM36H5O, KM42H5O). The general procedure involves removing the handle and cable clamp from the outdoor unit's right side plate, connecting the power connection cable to the terminal row, ensuring consistent wiring with the indoor unit, fixing the wire with a clamp, and then reinstalling the handle. It emphasizes the need for an all-pole disconnection switch with at least 3mm contact separation in all poles, connected in fixed wiring. Warnings are given against wrong wire connections, which can cause malfunction. After fixing cables, there should be some slack between the connection to the fixed point. The connection pipes and wirings of all units (A, B, C, D, E depending on the model) must correspond to each other. The appliance must be installed according to national wiring regulations. The manual provides tables specifying the required air switch capacity for each model.
The "HANDLING" section advises checking that the contents are intact and complete after unpacking. It states that the outdoor unit must always be kept upright and that handling should be done by suitably equipped and qualified technical personnel using appropriate equipment for the appliance's weight.
The "INSTALLING THE OUTDOOR UNIT" section covers location and piping. For location, bolts should be used to secure the unit to a flat, solid floor. If mounted on a wall or roof, the support must be firmly secured against intense vibrations or strong winds. The outdoor unit should not be installed in pits or air vents. For piping, suitable connecting pipes and equipment for R410A refrigerant must be used. Tables provide maximum connection pipe lengths for different models and for simple one indoor unit setups. The refrigerant pipes must not exceed specified maximum heights. All refrigerant pipes and joints must be wrapped. Connections should be tightened using two wrenches working in opposite directions.
A crucial part of installation is "BLEEDING" the refrigerant circuit to remove humid air, which can cause compressor malfunction. After connecting indoor and outdoor units, air and humidity are bled using a vacuum pump. The steps involve unscrewing and removing caps from 2-way and 3-way valves, then from the service valve. A vacuum pump hose is connected to the service valve, and the pump is operated for 10-15 minutes until an absolute vacuum of 10 mm Hg is reached. While the vacuum pump is still operating, the low-pressure knob on the vacuum pump coupling is closed, and the vacuum pump is stopped. The 2-way valve is opened by 1/4 turn and closed after 10 seconds. All joints are checked for leaks using liquid soap or an electronic leak device. Finally, the body of the 2-way and 3-way valves is turned, the vacuum pump hose disconnected, and all caps replaced and tightened. A table provides twisting moments for different pipe diameters. If an adaptor is required for connection, the method of pipe connection is also illustrated.
The "MAINTENANCE" section reiterates the use of suitable instruments for R410A refrigerant, and warns against using other refrigerants or mineral oils for cleaning.
The "INSTALLATION DIMENSION DIAGRAM" section provides guidelines for the outdoor unit's placement. It specifies minimum clearances: 30cm or above space to the cover, 200cm or above on the air outlet side, 50cm or more space to the cover, 30cm or above on the air inlet side, and 50cm or above space to the wall. Installation must be performed by trained and qualified service personnel. Users are advised to contact the service center to avoid malfunctions from unprofessional installation. When moving units, trained and qualified personnel should guide the process. The recommended space around the appliance must be maintained.
For fixing the outdoor unit's support, the manual advises selecting a location based on house structure and fixing the support with expansion screws. Protective measures should be taken during installation. The support must withstand at least four times the unit's weight. The outdoor unit should be installed at least 3cm above the floor for drain joint installation (20cm for models with heating tubes). The number of expansion screws required varies by cooling capacity: 6 for 2300W-5000W, 8 for 6000W-8000W, and 10 for 10000W-16000W. The shape of the drainage joint refers to the current product. Drainage joints should not be installed in severe cold areas to prevent frosting and malfunction.
Finally, the "CHECK AFTER INSTALLATION" section provides a checklist to ensure proper installation. It lists "Check Items" and corresponding "Problems Owing to Improper Installation." These items include checking if the installation is reliable (to prevent dropping, vibration, or noises), if gas leakage has been checked (to ensure satisfactory cooling/heating), if thermal insulation is sufficient (to prevent condensation and water dropping), if drainage is smooth (to prevent condensation and water dropping), if power supply voltage matches the nameplate (to prevent unit breakdown or component burnout), if lines and pipelines are correctly installed (to prevent unit breakdown or component burnout), if the unit is safely grounded (to prevent electrical leakage), if line models conform to requirements (to prevent unit breakdown or component burnout), if there are obstacles near air inlets/outlets of indoor/outdoor units (to prevent unit breakdown or component burnout), and if refrigerant pipe length and charge amount have been recorded (to facilitate deciding refrigerant charge amount).
