System components
Oil-free air compressor

1. High efficiency, silent, oil-free, continuous-duty rocking piston compressor.
2. Rubber compressor mounts reduce noise and vibration for silent operation.
3. SJT3x2.08mm2(14AWG)x1.8m plug power cord.
4. The solenoid valve can better protect the motor from starting with a load.
5. Single/double diffuser airflow valve.
6. The check valve can avoid the risk of water vapor backflow.
7. Capacitor that works as a part of the compressor. Do not operate the electrical connection of it.
8. Air Filter maximizes the life of the compressor.
9. Pressure relief valve safeguards from back pressure.

Airflow diffuser

1. EPDM non-stick 8″ membrane diffuser sticks provide the synergy of air stones while being virtually maintenance-free.
2. Stainless steel connector for the airline and the diffuser plate.
3. L 13.6″xW11.6″ square stainless steel base for the diffuser’s stability.

Airline

The 3/8″ 100 ft lead-free airline is made of durable PVC materials. Fish hook is resistant and kink-free. The connector kits that you need to connect the compressor to diffuser.

Installation **

**

• Step1: Find a place for the compressor to be ventilated and sheltered from rain, sunshine, also less dust.

• Step2: Screw the air filter into the compressor right near the pressure-relief valve. ( Use Teflon tape if needed.)
• Step3: Use your shovel to dig a trench from the shelter to the pond. The minimum depth of the trench should not be less than 8 inches to protect the air pipe. We recommend marking utility lines before starting excavation. If the length of the standard air tube is not enough, we can provide a longer air tube.
• Step4: Take the accessories attached, tighten the solenoid valve base and the 1/8 interface of the check valve, then tighten the square tube with the 1/4 thread, and then tighten the assembly with the exhaust hole of the air compressor cylinder head. After the above actions are completed, thread the molded shell of the solenoid valve onto the base and tighten it with a black screw cap. Note that all threaded connections need to use the raw material tape attached to wrap the threads to prevent poor sealing.

• Step5: Connect the two ends of the air pipe with the airflow valve on the air compressor and the pagoda connector on the aeration disk, and lock and fix them with a hose clamp.

• Step6: Screw and fix the aeration disk on the stainless steel base.

Operation

Please check the following items at least once a day during operation.

1. Is there any abnormal sound;
2. Whether the pump is abnormally hot;
3. Whether the exhaust is normal;
4. Is the muffler clogged?

MAINTENANCE
Pond Aeration Systems are designed for low-maintenance and require minimal scheduled maintenance. Keep the room cool, dry and ventilated for the compressor.

• Always unplug system before performing any maintenance or troubleshooting.
• Always unplug system and refer servicing to a qualified electrician when cord is damaged or frayed, compressor, power control, compressor fan, or other electrical components are producing unusual noises or odors.

WARNING: Compressors are equipped with a thermal overload switch. If temperature becomes high enough to trip the overload, the compressor will shut down. It will then automatically start up when temperature decreases as long as power is applied.
Please use only qualified service personnel with the same replacement parts to service your air compressor, which will ensure the safety of the electric air compressor.
