1. 제품 개봉 및 기본 사용법 익히기

1.1 주요 기술 사양

The equipment complies with the test requirements for IPX1, IPX2, IPX3, IPX4, IPX5, and IPX6 specified in GB/T 4208-2017, Sections 14.2.1 through 14.2.6, and Figures 3, 4, and 6.

Note 1: A complete Waterproof Test Chamber covers all six waterproof protection levels, from IPX1 to IPX6. The Waterproof Test Chamber you purchased may only include some of these levels. This manual is a general guide; please take this into account when operating the equipment.

Note 2: The appearance of the Waterproof Test Chamber may vary depending on the waterproof rating and dimensions, but the operating procedures remain the same.

1.2 Unboxing and Inspection

1.2.1 포장 해제 및 육안 검사

When unpacking the device, handle it gently to avoid scratching the casing with sharp objects. After unpacking, first inspect the exterior of the device to ensure there are no visible deformations or dents, and that the buttons are not damaged or loose. If you notice any abnormalities with the device or its accessories, do not turn it on. Please contact us immediately.

2. 안전상의 주의

2.1 전기 안전

2.1.1 Power Connection Specifications

Based on the nameplate, connect the test chamber to the correct input power supply: 220V/380V 50Hz (test chambers without IPX5 or IPX6 ratings require a single-phase 220V input, while those with IPX5 or IPX6 ratings require a three-phase 380V input;60 Hz is available upon request), and ensure the voltage and frequency are correct. Please use a dedicated circuit to avoid sharing the circuit with other high-power equipment. Confirm that all connections are secure and free of looseness.

2.1.2 접지 요구 사항

The test chamber must be reliably grounded, with a grounding resistance of ≤4 Ω. Do not use gas pipes, non-metallic water pipes, or the neutral wire as a substitute for the grounding wire. After grounding is complete, use the Grounding Resistance Tester to measure the ground resistance. Power may only be applied after confirming that the resistance meets the requirements, to prevent electric shock, test chamber malfunctions, or measurement errors caused by poor grounding.

2.1.3 Electrical Operation Precautions

Before wiring, inspecting, or maintaining equipment, the main power supply must be disconnected, and operations may only proceed after confirming that there is no residual voltage;

Do not operate the test chamber’s power switch, touchscreen, or instrument buttons with wet hands to avoid the risk of electric shock;

전기 제어 캐비닛 내부에는 먼지나 이물질이 들어가 단락을 일으키거나 부품을 손상시킬 수 있으므로 공구나 종이 등의 이물질을 넣지 마십시오.

Do not plug in or unplug power cords or signal cables while the equipment is running to prevent short circuits that could damage the controller or electrical components.

2.2 환경 안전

Sufficient clearance must be maintained between the equipment and walls, as well as surrounding fixtures (such as other test equipment and shelving), to ensure proper operation of the equipment and to facilitate operation and maintenance;

The test chamber should be placed on a solid, level surface; its adjustable feet can be used to ensure that the test chamber remains level.

3.3 Introduction to and Connection of the Test Chamber Back Panel

그렇지 않습니다.	주의 사항
① Sample Power Supply	If your sample requires power during testing, please connect the appropriate power source here based on your sample’s specific requirements. Short circuits may occur during testing, so please connect an external ground-fault circuit interrupter.
② Filtration System	The filter cartridge must be replaced when it has discolored significantly. (Note: If only IPX5 and IPX6 testing is included, there is no filtration device.)
③ Air Inlet	Used to connect to an air compressor (Note: This is used solely to quickly drain water from the IPX1/IPX2 drip tray; not connecting it to an air compressor does not affect the normal operation of the Waterproof Test Chamber at any waterproof rating.)
④ Inlet	Connect the corrugated hose to a clean water source, and keep the water supply valve open at all times.
⑤ Drain opening	The valve should remain closed at all times; it should only be opened when the tank needs to be cleaned or drained.
⑥ Power cord	Refer to the product nameplate and connect the device to the correct power source.

그림 7

Note 1: Before using the unit for the first time, inspect the test chamber, water tank, and all water lines, remove any debris, and clean them with clean water.

Note 2: We recommend using deionized water or purified water (a water purifier may be used). If tap water is used, the minerals and impurities it contains can easily cause scale buildup, which affects the test water flow rate. This may require frequent replacement of filter cartridges, unclogging of needles, cleaning of solenoid valves, and other maintenance, and may even damage the water pump.

3.4 Sample Connection and Installation

그렇지 않습니다.	주의 사항
①	If the sample requires testing under power, use the standard waterproof plug and socket for connection.
②	The test specimen must be secured to the center of the turntable using straps (Note: For IPX1 and IPX2 testing, the axis of the test specimen must be 100 mm from the axis of the turntable). If the test specimen has any protruding parts, ensure that it will not collide with the equipment while the turntable is rotating to prevent damage to both the equipment and the test specimen.
③	The turntable is height-adjustable; for IPX2 testing, the turntable must be tilted 15° and then secured in place.

2	Select the required waterproofing test level: IPX1 or IPX2
3	Adjust the flow meter to the standard water flow rate as described in Section 4.1.2.3.
4	Refer to Section 4.1.2.2 to configure the test parameters.
5	Following the instructions in Section 3.4, set up the sample and adjust the height of the turntable so that the drip tray is 200 mm away from the sample.
6	Close and lock the test chamber door.
7	If there is not enough water in the test chamber, click to add water.
8	If the sample requires a power-on test, please click “Sample Power Supply.”

6	Connect the sample as described in Section 3.4.
7	Close and lock the test chamber door.
8	If there is not enough water in the test chamber, click to add water.
9	If the sample requires a power-on test, please click “Sample Power Supply.”
10	Click “Reset” to clear the time from the previous test, then click “Start Test.”

7. 장비의 일상 유지보수 및 관리

7.1 일일 청소

If the sample contaminates the test chamber, clean it with clean water, drain the water from the tank, and refill it.

Thoroughly clean the water tank at least once a week. Drain any standing water, then wipe the tank dry with a clean cloth. After cleaning, check the interior walls of the tank for rust or scale buildup. If there is minor rust, gently wipe it with a rust remover, then rinse thoroughly with clean water.

7.2 Regular Inspections and Replacement

Needle: Check that the needle on the peristaltic tube is not clogged, loose, or deformed, and verify that the water is dripping evenly. If the needle is clogged, use a needle cleaner to clear the blockage.

Connections: Check all connections on the swing arm, water lines, and electrical circuits to ensure there are no leaks or loose connections.

Filter Cartridge: Check the filter cartridge inside the filter. If the cartridge has turned brown (indicating it is saturated with adsorbed impurities), replace it immediately with a new one.

7.3 Maintenance of Idle Equipment

7.3.1 Short-term idling (within 1 month)

Drain all standing water from the water tank and water lines to prevent scale buildup on the needles and tubing;

Cover the entire unit with a dust-proof cloth to prevent dust from entering;

Keep the equipment in a dry, well-ventilated area.

7.3.2 Long-term inactivity (more than 1 month)

Complete all maintenance tasks required for short-term storage; apply a layer of rust-preventative oil to the interior walls of the test chamber and water tank, as well as the surfaces of metal components, to prevent rust; store the equipment in a cool, dry place away from direct sunlight;

Apply a small amount of industrial lubricant to moving parts, such as turntable bearings, to prevent rust and jamming;

The equipment should be powered on once a month. Switch to the manual screen to test each function, and shut it down after 5 to 10 minutes of operation to prevent circuit degradation.
