This document describes the Anjon Manufacturing LifeLine Air Pump, specifically models LL-RP60P and LL-RP80P, which are air compressors designed for various applications, likely related to pond and water feature aeration given the context of other products offered by Anjon Manufacturing. The manual provides comprehensive information on installation, operation, maintenance, and troubleshooting.
Function Description
The Anjon LifeLine Air Pump is an air compressor designed to provide aeration. While the specific application isn't explicitly detailed on the cover, the "LIFELINE AIR PUMP" branding and the company's other products (pond liners, pumps, water treatments, filtering waterfalls) suggest its primary function is for pond and water garden aeration. The compressor works by drawing in ambient air, compressing it, and then expelling it through an exhaust port, often into an air stone or diffuser in a body of water to increase dissolved oxygen levels. The manual emphasizes the importance of proper installation, including the air filter for the inlet and a pressure release valve for the exhaust to manage excess pressure and prevent blockages.
Important Technical Specifications
The manual provides a "LifeLine Air Compressor Specifications Chart" and a "LifeLine Air Compressor Water Depth Pressure Chart" for both models:
LifeLine Air Compressor Specifications Chart:
- Model LL-RP60P:
- Volts: 120
- Amps: 3.5
- Hertz: 60
- Pump Dimensions: 10" x 6" x 7"
- Power Cord Length: 6'
- Model LL-RP80P:
- Volts: 120
- Amps: 7.5
- Hertz: 60
- Pump Dimensions: 10" x 7" x 7.5"
- Power Cord Length: 6'

These specifications indicate that both models operate on standard 120V AC power at 60Hz. The LL-RP80P draws more current (7.5 Amps vs. 3.5 Amps) and has slightly larger dimensions, suggesting it is a more powerful unit. This is confirmed by its higher CFM output at various water depths compared to the LL-RP60P. The CFM data is crucial for users to select the appropriate model based on the size and depth of their pond or water feature, ensuring adequate aeration.
Usage Features
The manual outlines several key usage features and recommendations:
- Box Contents: Each unit comes with 4 shock-absorbing mounts, 1 air filter, and 1 50 psi pressure release valve.
- Not Included: Users need to purchase an air fitting separately. For the LL-RP60P, a ¼" Male NPT / 3/8" Barb fitting is required, while the LL-RP80P needs a ¼" Male NPT / 5/8" Barb fitting.
- Recommended Air Hose: The LL-RP60P recommends a 3/8" LifeLine Weighted Air Hose, and the LL-RP80P recommends a 5/8" LifeLine Weighted Air Hose.
- Installation:
- The air filter must be installed into the inlet port.
- The pressure release valve should be installed into the exhaust port to prevent excess pressure in case of a blocked line.
- Check valves may be required to prevent backflow.
- The compressor should be mounted on a stable, rigid, and adequately ventilated surface, ideally in a well-ventilated enclosure, at least 12" from a wall or another compressor.
- The compressor should be protected from direct sunlight, dust, and debris.
- Plumbing lines should be bled before servicing.
- Electrical Requirements: The compressor must be plugged into a GFCI outlet that is properly installed and grounded. An extension cord, if used, should be heavy-wired and not exceed the recommended length.
- Operation:
- The user should ensure all fittings are tight and there are no air leaks.
- The compressor should be started and allowed to run for the first hour, then frequently for the next seven hours, checking for any irregularities.
- If the motor stalls or slows down significantly, the unit should be shut off and disconnected from power. The motor should turn freely by hand, and suction should be felt at the air inlet port when the fan is rotated. If not, the unit should not be connected to power.
- Safety First: The manual includes prominent warnings about injury hazards (moving parts, hot surfaces, loud noise), electrical shock hazards (grounding, GFCI outlets), and the importance of never lubricating any component in the LifeLine Air Compressor. It also warns against operating the compressor in areas with liquid or solid material that can cause serious injury or eye protection.
Maintenance Features
The manual provides detailed instructions for maintenance and repair, emphasizing regular inspections and timely replacement of parts to ensure optimal performance and longevity.
- General Maintenance:
- Disconnect the compressor from its electrical power supply before any maintenance.
- Vent all air lines.
- Remove the filter cover and replace the air filter as necessary.
- Clean the filter and determine how frequently filters should be checked during future operation.
- The manual recommends replacing the connecting rod, eccentric, and bearing assembly after 5000 hours, or 6-7 continuous months, of run-time to minimize unexpected downtime.
- It also recommends replacing O-rings for the head and valve plates, and flapper valves.
- Failure to maintain clean air filters can lead to clogging, excessive heat, and premature failure.
- NEVER lubricate any component in the LifeLine Air Compressor, as all moving parts are permanently lubricated.
- Troubleshooting Guide: A table is provided to help diagnose common problems (low flow, low pressure, unit will not start, motor overheats, loud unit) and their possible causes and corrective actions.
- Exploded Diagram & Service Parts List: A detailed diagram with numbered parts and a corresponding list with item numbers, quantities per unit, and descriptions (e.g., connecting rod & eccentric wheel & bearing assembly, piston cup, cylinder sleeve, heads, O-rings, valve plate assembly, flapper valves, fan) are included for easy identification of components during repair.
- Disassembly & Reassembly: Step-by-step instructions are provided for disassembling and reassembling the LL-RP60P / LL-RP80P models, including required tools like a torque wrench, Phillips screwdriver, and Allen wrench.
- Component Repair:
- Servicing the Head: Instructions for disconnecting power, removing the compressor from its enclosure, removing head screws, separating the head from the compressor body, and removing/replacing valve plate assemblies and O-rings.
- Servicing the Valve Plate Assembly (Top-Side & Bottom-Side): Detailed steps for removing and replacing flapper valves, valve keeper strips, and valve restraints. It recommends replacing one flapper valve at a time to simplify the process and ensure correct orientation. Cleaning debris from the valve plate with fish-safe cleaning chemicals is advised. Torque specifications (1.3 Nm) are given for flapper valve screws.
- Servicing the Connecting Rod & Eccentric Assemblies: Instructions for determining if parts need servicing or if the entire assembly needs replacement. It emphasizes removing only one connecting rod assembly at a time.
- Connecting Rod & Eccentric Wheel Assembly Removal: Steps include carefully removing the fan by pulling it straight off the motor shaft (without pulling blades), turning the motor shaft to align the eccentric wheel set screw with the access hole, sliding the eccentric bearing assembly off the shaft, and then sliding and rotating the connecting rod out of its housing.
- Rebuilding Connecting Rod Assemblies: Instructions for removing and replacing piston cup retainer screws, piston cups, and cylinder sleeves. It warns against damaging the compressor housing when removing the piston cup and emphasizes that if the piston cup is damaged, it must be replaced. Torque specifications (3.0 Nm) are given for piston cup retainer screws.
- Assembly of the Connecting Rod to the Compressor: Steps for inserting the cylinder sleeve, replacing the eccentric bearing, and rotating the shaft to check for free movement. Torque specifications (4 – 4.5 Nm) are given for the eccentric wheel set screw.
- Reassembling the Compressor: Instructions for inserting the O-ring for the valve plate, positioning the compressor housing, observing the orientation of the valve plate assemblies, inserting new O-rings for the head, placing the head on the valve plate assemblies, and inserting/tightening head screws. Torque specifications (4 – 4.5 Nm) are given for head screws, with a specific tightening sequence indicated.
- Servicing the Fan: Instructions for removing a broken fan by pulling it straight off the motor shaft and aligning a new fan with the flat part of the motor shaft, ensuring fan clips face towards the compressor.
