1. Unboxing and Basic Familiarization with the Equipment

1.1 Key Technical Specifications

Note: The internal dimensions and maximum load capacity of the water tank can be customized.

The device complies with the test requirements for IPX7 specified in Section 14.2.7 of GB/T 4208-2017.

1.2 Unboxing and Inspection, and Introduction to the Equipment

1.2.1 Unpacking and Visual Inspection

When unpacking the device, handle it gently to avoid scratching the outer casing with sharp tools. After unpacking, first inspect the exterior of the device to ensure there are no visible deformities, dents, or other damage. If you notice any abnormalities with the device or its accessories, please contact us immediately.

2. Safety Precautions

2.1 Operational Safety

2.1.1 Safety Precautions for Handling Test Specimens

Handle test specimens with care when removing them from or placing them into the tank to prevent slipping and falling into the test tank; test specimens may be secured with a nylon rope or steel chain before being placed in the water to facilitate handling; ensure that the test specimens are fully submerged and do not shift during the test.

2.1.2 Safety During the Trial

When observing conditions inside the chamber during the test, it is strictly prohibited to open the water tank or adjust the position of the test specimens without authorization.

2.2 Safety in Equipment Placement and Movement

2.2.1 Equipment Placement Requirements

The equipment must be placed on a level, sturdy surface near a water source and a drain. After placement, lock the casters, level the unit, and secure the foot cups to prevent the equipment from sliding. Position the side with the water level gauge facing outward to avoid obstructing the observation area.

2.2.2 Equipment Relocation Requirements

Before moving the unit, be sure to drain all standing water from the case, loosen the foot cups, and release the casters’ brakes. Avoid collisions and jolts during transport to prevent damage to the case’s glass and metal components.

3. Preparations Before the Test

3.1 Sample Preparation

Clean the surface of the test specimen thoroughly to remove dust, oil, and impurities, and prevent contaminants from entering the test water and affecting the test results; Inspect the specimen’s exterior to ensure there are no breaks or cracks, and assemble the specimen according to the manufacturer’s specified installation instructions. If the specimen requires electrical power during testing, please prepare an additional power source and a waterproof power cord as needed based on the specimen’s power requirements.

3.2 Preparation of Test Water

3.2.1 Requirements for Test Water

Prepare the test water in advance so that the temperature difference between the water and the sample to be tested is ≤5°C.

3.2.2 Injection and Drainage of Test Water

Before filling the tank with water, please clean the inside of the tank to ensure there are no foreign objects.

4. IPX7 Water Immersion Test Procedure

4.1 Placing the Test Specimens in the Chamber

Slowly place the secured test specimen into the test tank, ensuring that the specimen is positioned in accordance with the specified installation requirements and that it does not tip over or shift; Verify that the submersion condition meets the requirements of GB/T 4208-2017 based on the specimen’s height: for specimens with a height < 850 mm, the lowest point must be 1000 mm below the water surface; for specimens with a height ≥ 850 mm, the highest point must be 150 mm below the water surface.

If a test specimen must be tested while energized or in operation, the test conditions (water temperature, immersion method, etc.) must be adjusted in accordance with the relevant product standards. Ensure proper electrical safety precautions are taken during the test; do not touch energized test specimens with your hands to prevent electric shock.

4.2 Test Timing and Process Observation

Once the test specimens have been properly positioned and secured, start the timer; the test duration is 30 minutes. Once the timer has started, do not adjust the position of the test specimens or change the water level in the tank without authorization;

During the test, you can walk around the equipment to observe the condition of the test specimens inside the water tank. Look through the tempered glass window to check whether the specimens have shifted or are floating, and keep detailed records of your observations throughout the process.

4.3 End of Timing and Initial Inspection of Test Specimens

After the 30-minute test period has elapsed, stop the timer; slowly remove the test specimen from the water, allow the surface water to drain off, and conduct a preliminary visual inspection of the specimen’s outer casing for any obvious signs of water ingress, deformation, or damage.

5. Post-Test Procedures

5.1 Evaluation of Test Results

Use a dry cloth to wipe away any water stains from the outer surface of the sample, and then test the sample. Determine whether the sample has passed the test based on the following criteria.

5.2 Real-Time Equipment Operation

If the test water is clean and free of turbidity, the water in the tank may be retained for subsequent tests;

If the test water becomes contaminated or cloudy, or if oil or impurities from the test sample are introduced into the water, the water tank must be drained, cleaned, and refilled immediately.

6. Daily Maintenance and Care of Equipment

6.1 Regular Cleaning

6.1.1 Cleaning the Inside of the Water Tank

If dirt or scale is found on the inner walls of the water tank after testing, clean it promptly with a long-handled cleaning brush to prevent the buildup of impurities. Do not use corrosive cleaning agents under any circumstances. After cleaning, rinse thoroughly with clean water to ensure no cleaning agent residue remains inside the tank.

6.1.2 Cleaning the Exterior of the Equipment

Wipe down the equipment housing, water level gauge, and glass viewing window with a dry or damp cloth to keep the equipment surfaces clean; if the glass viewing window is dirty, wipe it with a specialized glass cleaner to ensure a clear view; wipe the water level gauge regularly to prevent scale buildup from obscuring the markings.

6.2 Equipment Storage and Maintenance During Downtime

6.2.1 Short-Term Idle Maintenance (7 days or more, but less than 1 month)

Drain all water from the tank, clean it, and wipe it dry to keep the interior dry; close all valves, disconnect the water lines, and neatly coil the hoses before placing them next to the equipment; cover the equipment with a dust-proof cloth to prevent dust from entering.

6.2.2 Maintenance During Long-Term Idle Periods (1 month or longer)

In addition to meeting the requirements for short-term storage and maintenance, apply a layer of rust-preventive oil to the inner walls of the tank and the surfaces of metal components to prevent rust; store the equipment in a cool, dry place away from direct sunlight.
