4. Fire Extinguisher Placement:

• Keep appropriate fire extinguishers readily available when performing hot work on the refrigeration system or related components. Dry powder or carbon dioxide fire extinguishers should be available in the refrigerant charging area.

5. Prohibition of Open Flames:

• When working with or near lines containing or having contained flammable refrigerants, do not use any form of open flame that could cause ignition or explosion. Remove all open flames, including smoking, from the work area if flammable refrigerants may be released into the surrounding environment. Inspect the work area for any fire hazards before starting work and post "No Smoking" signs.

6. Ventilation:

• Ensure the work area is open or well-ventilated before opening the system or performing hot work. Ventilation will safely dilute any leaked refrigerant and quickly dissipate it into the atmosphere.

Refrigeration Equipment Inspection:

• When replacing electrical components, ensure they are installed according to their intended use and proper operating procedures. Always follow the manufacturer's maintenance and repair guidelines. Consult the manufacturer's technical department if you have any questions.
• For appliances using flammable refrigerants, the following inspection items apply:
• (1) Recharge the system according to the rated capacity indicated on the nameplate.
• (2) Ensure ventilation equipment is operating correctly and that ventilation openings are unobstructed.
• (3) If using an indirect refrigeration cycle, check the secondary circuit for refrigerant.
• (4) Ensure all labels on the appliance are clear and legible. Replace any unclear or missing labels.
• (5) Refrigerant lines or electrical components should not be installed in environments that could corrode refrigerant-containing components, unless the electrical components are made of corrosion-resistant materials or have appropriate corrosion protection.

Electrical Equipment Inspection:

• Maintenance and repair of electrical components include initial safety checks and component inspections. If safety defects are found, disconnect the appliance's power supply until the defects are properly rectified. If defects cannot be completely eliminated and operation must continue, take appropriate temporary measures and report the situation to the appliance owner, warning all relevant personnel.
• Initial safety checks should include:
• (1) Capacitor discharge: Perform safely to prevent sparking.
• (2) Ensure no exposed electrical components or wiring during charging, recovery, and cleaning of the system.
• (3) Continuity of grounding.

Sealed Component Maintenance:

• When servicing sealed components, disconnect the appliance's power supply before opening any sealed covers. If power is required during maintenance, continuously monitor for leaks in the most hazardous areas to prevent potential dangerous situations.
• Pay special attention to maintenance procedures for electrical components that may affect the enclosure's protection rating. Improper maintenance may lead to: damaged cables, incorrect connections, improperly installed terminals, damaged seals, or incorrectly installed sealing covers.
• Ensure the equipment is installed safely and securely.
• Ensure that seals or sealing materials do not lose their ability to prevent flammable gas from entering due to aging. Replacement parts must comply with the manufacturer's specifications.

Maintenance of Intrinsically Safe Components:

• If it cannot be ensured that the appliance will not exceed the rated voltage and current limits during use, do not use any permanent inductive or capacitive loads in the circuit.
• Intrinsically safe components are the only components that can continue to operate in a flammable gas atmosphere. Set the test instrument to the correct range.
• When replacing components, use only manufacturer-specified parts. Other components may cause refrigerant leaks that ignite in the air.

Wiring:

• Inspect wiring for abrasion, corrosion, over-voltage, vibration, sharp edges, or other adverse environmental factors. This inspection should also consider the effects of aging or continuous vibration from the compressor or fan.

Flammable Refrigerant Inspection:

• Inspect for refrigerant leaks in an environment without potential ignition sources. Do not use halogen detectors (or any other detectors using open flames) for detection.

Leak Detection Methods:

• For systems containing flammable refrigerants, the following leak detection methods are acceptable:
• Electronic leak detectors can be used for flammable refrigerant detection, but their sensitivity may not be sufficient, or they may require recalibration (recalibration should be done in a non-refrigerant environment). Ensure the leak detector does not become a potential ignition source and is suitable for the refrigerant being tested. The leak detector should be set to the lowest flammable concentration of the refrigerant (expressed as a percentage) and calibrated to the appropriate gas concentration test range (maximum 25%).
• The fluid used for leak detection is suitable for most refrigerants, but do not use chlorinated solvents to prevent reactions between chlorine and refrigerants, or corrosion of copper pipes.
• If a leak is suspected, remove all open flames from the area or extinguish them.
• If welding is required at the leak location, all refrigerant must be recovered, or the refrigerant must be completely isolated from the leak point (using shut-off valves). Before welding, and during welding, the entire system must be purged with oxygen-free nitrogen (OFN).

Removal and Vacuuming:

• When performing maintenance or other operations on the refrigeration circuit, follow standard procedures. However, pay special attention to the flammability of the refrigerant and follow these steps:
• (1) Recover refrigerant.
• (2) Purge the system with inert gas.
• (3) Vacuum.
• (4) Purge the system again with inert gas.
• (5) Cut pipes or perform welding.
• Refrigerant should be recovered into suitable storage tanks. The system must be purged with oxygen-free nitrogen to ensure safety. This process may need to be repeated several times. Do not use compressed air or oxygen for this operation.
• The purging process involves charging the system with oxygen-free nitrogen to working pressure while the system is under vacuum, then releasing the oxygen-free nitrogen into the atmosphere, and finally evacuating the system. Repeat this process until all refrigerant is removed. After the final charge of oxygen-free nitrogen, release the gas to atmospheric pressure, and the system can be welded. If pipe welding is to be performed, the above operations are necessary.
• Ensure there are no ignition sources near the vacuum pump outlet and that ventilation is adequate.

Refrigerant Charging Procedure:

• In addition to standard procedures, the following requirements apply:
• Ensure that refrigerant charging equipment is not contaminated with different refrigerants. Keep refrigerant charging lines as short as possible to minimize residual refrigerant.
• The storage tank should be kept upright.
• Ensure the refrigeration system is grounded before charging refrigerant.
• Apply a label to the system after charging (or before completion) according to the rated value.
• Do not overcharge.
• Perform a pressure test with oxygen-free nitrogen before recharging the system. Conduct a leak test after charging and before the unit starts running. Conduct another leak test when leaving the area.

Scrapping:

• Before performing this procedure, technicians should be fully familiar with the equipment and its characteristics. It is recommended to implement safe refrigerant recovery practices. If recovered refrigerant is to be reused, analyze samples of the refrigerant and oil before use. Ensure the required power supply is available before testing.
• (1) Familiarize yourself with the equipment and operation.
• (2) Disconnect the power supply.
• (3) Ensure the following before proceeding:
• If necessary, the mechanical operation of the equipment should facilitate the handling of the refrigerant storage tank.
• All personal protective equipment is effective and properly used.
• The entire recovery process should be supervised by qualified personnel.

Recovery:

• Appliance and storage tanks must comply with relevant standards.
• (4) If possible, vacuum the refrigeration system.
• (5) If vacuum cannot be achieved, draw from multiple points to remove refrigerant from all parts of the system.
• (6) Ensure the storage tank has sufficient capacity before starting recovery.
• (7) Operate the recovery equipment according to the manufacturer's instructions.
• (8) Do not overfill the storage tank (liquid fill should not exceed 80% of the tank's capacity).
• (9) Do not exceed the maximum working pressure of the storage tank, even for short periods.
• (10) After filling the storage tank and completing the operation, quickly move the storage tank and equipment away, and ensure all shut-off valves on the equipment are closed.
• (11) Recovered refrigerant must not be introduced into another refrigeration system until it has been purified and tested.

Labeling:

• After the appliance is scrapped and the refrigerant is evacuated, it should be labeled with the date and signature. Ensure the label reflects the type of flammable refrigerant contained in the appliance.

Recycling:

• When servicing or scrapping, the system's refrigerant must be removed. It is recommended to remove the refrigerant completely.
• Use only dedicated refrigerant storage tanks for refrigerant transfer. Ensure the storage tank's capacity is suitable for the total amount of refrigerant in the system. All tanks intended for refrigerant recovery must be labeled as such (i.e., dedicated refrigerant recovery tanks). Tanks should be equipped with pressure relief valves and shut-off valves and be in good condition. If possible, empty tanks should be vacuumed and kept at room temperature before use.
• Recovery equipment should be in good working order, with operating instructions readily available, and suitable for recovering flammable refrigerants. Additionally, calibrated weighing instruments should be used. Hoses should be connected with leak-proof quick-connect fittings and be in good condition. Inspect the recovery equipment for proper condition and maintenance before use. All electrical components should be sealed to prevent fire hazards from refrigerant leaks. Consult the manufacturer if you have any questions.
• Recovered refrigerant should be stored in suitable tanks and returned to the refrigerant manufacturer with shipping instructions. Do not mix refrigerants in the recovery equipment, especially in the storage tanks.
• When removing the compressor or compressor oil, ensure the compressor is vacuumed to an appropriate level to remove any residual flammable refrigerant from the lubricating oil. Vacuuming should be performed before returning the compressor to the supplier. Only use electric heating to warm the compressor casing to speed up this process. Ensure safety when draining oil from the system.

Installation Instructions

1. The outdoor unit installed near the street must not be less than 2.5 meters high.
2. Firmly fix the mounting bracket to the wall to prevent strong winds from affecting it. Use expansion bolts of consistent specifications, at least 4 bolts with a diameter of 10mm or more. Then, securely fasten the outdoor unit to the bracket, ensuring it is level.

Drain Elbow Installation:

1. Install the drain elbow as shown in the diagram.
2. Do not use the drain elbow in very cold areas (ambient temperature below 0°C).

Vacuuming Method (R32):

Steps for vacuuming with a vacuum pump:

1. Remove the cap from the shut-off valve. Connect the hose to the service valve of the three-way shut-off valve and the vacuum pump via the manifold gauge and diversion device.
2. Fully open the low-pressure side knob of the manifold gauge. Turn on the vacuum pump power.
3. Vacuum for 15 minutes. Check the low-pressure side pressure reading. It should reach -0.1MPa (-76cmHg). Then, close the low-pressure side knob of the manifold gauge and turn off the vacuum pump. Maintain pressure for 5 minutes. If the pressure drop does not exceed 0.005MPa, check and retighten the connections, then repeat step 3.
4. After vacuuming, slightly open the liquid valve to release gas and balance the system pressure, preventing air from entering when disconnecting the pipes. Then, fully open the high and low-pressure valves.
5. Tighten all valve caps and check for leaks.

Connecting Pipes:

• Connect the connecting pipes first to the indoor unit, then to the outdoor unit. Connect the low-pressure pipe first, then the high-pressure pipe.
• Do not overtighten the connector nuts, as this may cause leakage. Refer to the table for tightening torque:

Connecting Pipe Installation Tips:

1. Align the connecting pipe flare nut with the corresponding valve fitting cone.
2. Tighten the connecting pipe nut firmly, then use a wrench to tighten it.
3. After tightening, secure the joint with a protective cap.
4. The indoor unit's flare nut cannot be reused. If secondary connection is required, the flare nut must be reprocessed.
5. After connecting the indoor unit, install the protective cap and seal with silicone to prevent disassembly.
6. For installation, maintenance, or relocation, contact Haier after-sales personnel. Non-professional personnel are prohibited from performing these operations.
7. According to the air conditioner standard GB4706.32, the indoor unit uses a non-reusable connector. The installation method is the same as a standard connector.
