Biochemical filter media pack Fine-mesh filter cotton Coarse-mesh filter cotton Water pump assembly ② Rinse the two filter cottons under running water by gently scrubbing.Reinsert them into the filter module in their original order. ③ During deep cleaning, lightly rinse biochemical filter media with tank water only (never use tap water). 7.4 Clean The Water Pump Assembly 7.5 Reinstall the filter chamber. Refer to the product installation section in the manual. T-shaped connector outlet hose (thick) oxygen regulating valve intake hose clip UV water pump Note:Avoid vigorous scrubbing, as this may generate excess debris and shorten the bio-media’s lifespan. Not Suitable:Turtles, large goldfish (e.g., Common Goldfish, Koi), Arowanas, or any species exceeding 15 cm (6 inches) in adult size. * Warning: Overstocking or housing incompatible species may stress fish and compromise water quality. Sunlight Tracking Mode 材质：80g书纸，2色印刷， 封装：钉装, 24P 尺寸：140*140mm Note: Coarse-mesh filter cotton *1 Anti-slip pad *1 ② Remove the biochemical filter media pack.Rinse the biochemical filter media pack under running water until the water runs clear.(Note: Minor shedding or dusting is unavoidable due to the material properties of the biochemical filter media. Avoid vigorous scrubbing during rinsing to prevent excessive particle release.) ① Open the filter compartment cover.Place the UV water pump assembly at the base of Compartment 4 as illustrated.Insert the T-shaped connector into the outlet hose interface as shown, ensuring a secure fit. ③ Gently place the rinsed biochemical filter media pack into the base of Compartment 3.If the pack gets stuck, gently compress it to adjust its position for even distribution before reinserting.Ensure the biochemical filter media remains fully submerged during operation. ⑤ Insert the coarse-mesh filter cotton into Compartment 1 and the fine-mesh filter cotton into Compartment 2.Press firmly on the upper edge of each pad during installation, allowing it to naturally expand, and ensure proper seating.(Critical: Do not trim the original filter cottons. Full compartment coverage is essential for optimal filtration.) ⑥To install additional equipment (e.g., a heater), place it in Compartment 4.For best compatibility and performance, use the ERAARK Constant-Temperature Aquarium Heater. ② When the light panel is fully closed, the lighting system will be forcibly deactivated, and neither the touch controls nor the app will be able to operate the lights. (Keeping the light panel lifted helps maintain optimal airflow and cooling for the aquarium. We recommend mai…

FCC 47CFR §2.1091 REQUIREMENT 2.1 TEST STANDARDS The limit for Maximum Permissible Exposure (MPE) specified in FCC 1.1310 is followed. The gain of the antennas used in the product is extracted from the Antenna data sheets provided and also the maximum total power input to the antenna is measured. Through the Friis transmission formula and the maximum gain of the antenna, we can calculate the distance, away from the product, where the limit of MPE is reached. Although the Friis Transmission formula is far field assumption, the calculated result of that is an over-prediction for near field power density. It is taken as worst case to specify the safety range. 2.2 LIMIT According to FCC 1.1310: The criteria listed in the following table shall be used to evaluate the environmental impact of the human exposure to radio-frequency (RF) radiation as specified in 1.1307 (b) Limits for Maximum Permissible Exposure (MPE) Frequency Range (MHz) Electric Field Strength (V/m) Magnetic Field Strength (A/m) Power Density (mW/cm²) Limits for Occupational / controlled Exposures 300 - 1500 -- -- F/300 3.0-30 1842/f 4.89/f *(900/f²) 1500 – 100000 -- -- 5.0 Limits for General population / Uncontrolled Exposure 300 - 1500 -- -- F/1500 1.34-30 824/f 2.19/f *(180f²) 1500 – 100000 -- -- 1.0 F= Frequency in MHz Friss Formula Friss Transmission Formula: Pd = (Pout * G) / (4*pi*r²) Where Pd = power density in mW/cm² Pout = output power to antenna in mW G = gain of antenna in linear scale Pi = 3.1416 R = Distance between observation point and the center of radiator in cm If we know the maximum gain of the antenna and the total output power to the antenna, through calculation, we will know MPE value at distance 20cm.
