Pet Friend HD-602 Fish Tank Air Pump Kit - Adjustable Single Outlet Valve

• HD-602 ADJUSTABLE FLOW CONTROL: Powered by an energy-saving 2.5W motor with an integrated dial to easily alter bubble intensity. Delivers up to 2.0 Litres Per Minute (LPM) via a single outlet for tanks ranging from 50 up to 300 Litres.
• WHISPER-QUIET 35dB OPERATION: While top-selling competitors hum along at a noisy 40dB, the HD Series operates at an ultra-low 35 decibels—making it noticeably quieter than the market average. Engineered with a thick, sound-insulating shell and vibration-dampening rubber feet, it eliminates annoying cabinet rattle to deliver powerful, near-silent aeration you’ll barely notice.
• COMPLETE ALL-IN-ONE ACCESSORY KIT: Every pump comes fully loaded with a complete installation kit, containing premium porous air stones for dense bubble generation, standard flexible airline tubing, and a non-return check safety valve.
• VERSATILE SYSTEM OXYGENATION: Engineered with deep-water pushing power so the air flow won't fizzle out at the bottom of your tank. It provides plenty of steady punch to easily run sponge filters, under-gravel filtration grids, long air curtains, decorative ornaments, and oxygen-rich bubble walls across freshwater, tropical, and marine setups.
• ANTI-SIPHON SAFETY PROTECTION: Non-submersible design engineered to run external to the tank. The included inline non-return check valves provide total protection, preventing gravity from siphoning tank water backwards down the line into electrical components during power cuts.

Product description Pet Friend HD-602 High-Efficiency Aquarium Air Pump Kit (Single Outlet - Adjustable) Ensure your aquatic environment stays dynamically rich in vital oxygen with the Pet Friend HD-602 Aquarium Air Pump Kit. Engineered with an advanced, low-vibration air compressing system, this compact single-outlet aerator provides constant, reliable airflow without taking up massive amounts of space outside your tank. Perfect for freshwater, tropical setups, and marine aquariums, the HD-602 is designed to drive healthy water circulation and power your favorite bubble decorations smoothly. Quiet Operation & Vibration-Dampening Build Traditional air pumps can create annoying buzzing sounds against your cabinet structures. The Pet Friend HD-602 eliminates this by utilizing a rigid, high-density ABS plastic protective casing paired with heavy-duty rubberized shock-absorbing feet. This design dampens internal motor frequencies and absorbs excess operational vibrations, giving you a serene indoor environment where you hear the peaceful sound of popping water bubbles rather than the mechanical hum of the pump. Adjustable Flow Control & Low Power Consumption Keep your energy bills low while prioritizing the health of your community fish and shrimp. Operating on a highly efficient 2.5-watt motor, this small-profile air compressor features an integrated, multi-speed adjustment dial allowing you to dial the air intensity up or down to suit your exact setup. It delivers a robust, customizable flow rate up to 2.0 Litres Per Minute (LPM). This system produces excellent backpressure capable of driving standard air stones, under-gravel filter grids, or sponge filters effortlessly in medium to large tanks ranging from 50 up to 300 Litres. Complete Immediate Setup Accessory Kit Included The HD-602 comes supplied as a complete all-in-one hardware kit ready for immediate out-of-the-box installation. Inside the package, you will receive the high-performance 2.5W single-valve adjustable air pump, a premium porous air stone for dense bubble cloud production, a continuous run of standard flexible airline tubing, and a critical non-return safety check valve to safeguard your pump from water siphoning accidents. Safety-First Maintenance & Siphon Compliance This premium non-submersible unit is designed to sit safely on the outside of your tank framework and comes fitted with a standard UK 3-pin plug. To protect your investment, always install the included non-return safety check valve inline along your air hose, or ensure the pump is positioned physically higher than your aquarium’s top water line. This prevents gravity from siphoning water backwards down the tubing into your electrical components during domestic power cuts.

Inspection & Assembly - Carefully inspect the outer ABS safety shell and internal quartz glass tube for any signs of shipping damage before handling. Do not plug the unit into the mains power yet. - Ensure the rubber suction cups are firmly attached to the dedicated mounting tracks on the back of the protective plastic shell. 2. Submersion & 45-Degree Placement - Mount the heater body completely inside the aquarium against the glass, positioning it at an optimal 45-degree angle (or vertically) near a filter outlet or water pump to guarantee uniform heat circulation. - Important: The entire heater body and the ABS guard must be completely submerged below the water level. - Mount the Digital Controller Module outside the aquarium in a dry area near your power socket. Never allow the external controller to fall into the water or get wet. - Leave the unit unplugged in the water for 15 to 20 minutes before powering it on. This acclimation period allows the internal temperature sensors to match your current tank climate accurately. 3. Powering On & Programming - Ensure your hands are dry. Form a mandatory drip loop with the power cable below your wall socket to prevent any stray water droplets from traveling down the wire into the outlet. - Plug the unit into a standard 220-240V wall socket and switch the power on. - Press the button on the external inline controller repeatedly to set your target temperature. Hold the set button down for 3 seconds to toggle the display panel between Celsius (°C) and Fahrenheit (°F). - The display will show an active Red light while heating, turning Blue once your target temperature is stably reached. 4.
