System Installation

Tech Specs:| HP| Running Amps| Volts| Max CFM| Power Cord| Max Pond Size| Max Depth| # Diffusers
---|---|---|---|---|---|---|---|---
LS80| ¾ (x2)| 8.6 or 4.3| 115v or 230v| 11.2| 6′| 8 Acres| 50′| 4 to 8
LS120| 1 (x2)| 6.3| 230v| 14.2| 6′| 12+ Acres*| 50′| 6 to 12

*Ponds greater than 12 Acres require multiple systems

Tools Required:

• Placement rope
• Level
• Small stone or gravel
• Rake
• Permanent marker
• Utility razor knife
• Boat/Raft/Swimsuit
• Shovel
• Flathead screwdriver or nut driver
• Coast Guard-approved life jacket

STEP ONE: Select a Location for the Aeration Cabinet

• Locate cabinet on a solid surface with adequate strength for the weight of the unit.
• Locate cabinet away from irrigation sprinklers.
• Cabinet must always remain above the high water mark.
• Attention: For airline runs longer than 100’, connector kits are required (sold separately). See Replacement Parts (Page 10).
  • If a power source is available near the pond’s shore, locate the cabinet at the pond’s edge for quicker installation.
  • If a power source is not available near the pond’s shore or you would prefer to install the cabinet in another location, install Direct Burial Airline(s) (sold separately) from the cabinet’s location to the pond’s edge.

STEP TWO: Prepare Ground Surface and Place Cabinet

1. Place the cabinet on the ground and mark out an area approximately 6” wider than the cabinet base on all sides. Set the cabinet aside.

2. Level the cabinet area with a shovel and/or rake.
   Note: Systems resting on turf or mulch benefit from greater sound reduction.

3. At the backside of the cabinet location, dig a short trench approximately 20-24” wide x 8” deep to allow for manifold flex tube runs and airline connections.

STEP THREE: Excavate Trench and Place Airline(s)

1. Trench from far side of hole to the pond’s edge, approximately 8” deep.
2. Set cabinet in place and feed manifold hoses from beneath the cabinet base into the trench.
3. Place airline in the trench from the cabinet to the pond’s edge.

• Option A: (when distance between cabinet and shore is less than 5’)
  Use EasySet weighted airline. There must be a separate run of airline for each diffuser that will be installed. Leave remaining airline coiled at the pond’s edge.

• Option B: (when distance between cabinet and shore is more than 5’)

  • Use Direct Burial airline. There must be a separate run of airline for each diffuser that will be installed. Join multiple sections of direct burial airline using 5/8” connector kits.
  • First, slide two hose clamps onto one section of airline. Next insert the 5/8” insert adapter halfway into one section of airline and then insert into the next section of airline.
  • Using a flathead screwdriver or nut driver, secure one of the hose clamps onto each half of the insert adapter (see image on the left).

• Option B with Remote Manifold:
  Refer to the Remote Manifold Kit manual or watch the installation video at airmaxeco.com/RemoteManifold for more information.

STEP FOUR: Connect Airline(s) to the Compressor Manifold

• Option A & B:
  Insert one side of a 3/8” to 5/8” coupler into the 5/8” weighted or direct burial airline and secure with a hose clamp. Then insert the other side of the coupler into the manifold hose and secure with a hose clamp. Repeat for each diffuser line (see image on the left).

• Option B with Remote Manifold:
  Refer to the Remote Manifold Kit manual or watch the installation video at airmaxeco.com/RemoteManifold for more information.

STEP FIVE: Partially Backfill Airline Trench
Backfill the airline trench in a few areas to temporarily keep airline in place until installation is complete. STEP SIX: Connect Weighted Airline for Diffusers

• Unroll the EasySet weighted airline and remove any twists. Join enough sections of weighted airline, using 5/8” connector kits, so that the airline can rest on the bottom of the pond, from the pond’s edge out to the planned location for each diffuser. For Option B installations, connect the weighted airline to the direct burial airline or Remote Manifold Kit at the pond’s edge.
• Note: Diffusers should be placed equally apart or in areas of low water movement for optimum performance. If you need help choosing the correct location for your diffusers, please contact Airmax or your local dealer.

STEP SEVEN: Assemble and Connect ProAir Diffusers
See the ProAir Diffuser manual for assembling and connecting the diffusers.

STEP EIGHT: Start the Aeration System
Plug compressors and cooling fans into the power control outlet inside of the cabinet (Fig. 1). With the external shut off switch in the off position, plug the cabinet power cord into a GFCI power outlet. Then, turn the external shut off switch to the on position (Fig. 2). STEP NINE: Install the ProAir Diffusers

• Installing Diffusers From a Boat/Raft: Have one person on shore guiding the airline as a second person, using a boat or raft, extends the airline out to the area of the pond where the diffuser will be located. Gently lower the diffuser to the pond bottom using the weighted airline to ensure that the ProAir 4 diffuser remains in the upright position. You may also choose to thread nylon rope through the diffuser manifold and use the nylon rope to gently lower the diffuser until it reaches the pond floor.
• Release one side of the nylon rope and remove. Repeat until all diffusers are in position.

STEP TEN: Adjust Airflow

• Bubbles should be noticeable on the pond’s surface from the diffuser locations. Adjust the airflow valves on each manifold assembly to achieve uniform patterns at all diffusers. For Option B with Remote Manifold, do this step at the remote manifold. Once an adjustment is made, you may need to wait several minutes to see the results at the diffuser location(s).
• Note: Deeper placement of diffusers and longer runs of airline will require more flow.

STEP ELEVEN: Mark Pressure Gauge
Using a permanent marker, mark the current pressure gauge reading. During regularly scheduled filter changes, if the reading is above or below this mark, it may indicate that the system requires maintenance.

STEP TWELVE: Backfill Trench and Secure Cabinet Lid
Close the cabinet lid and use one of the keys provided to secure. Locking the cabinet lid will eliminate unwanted vibration. Inspect all airline connections in the trench and at the manifold hoses to ensure all hose clamps are secure and free of leaks. Backfill the remainder of the trench from cabinet to shore.

Initial Start-Up & Seasonal Operation

• The circulation of poor quality, low oxygen, deep water to the pond’s surface can introduce harmful gases and by-products into the previously healthy upper regions of the water column. These by-products can make the upper regions unfit for aquatic life and could result in fish kill.
• Initial Start-Up Procedure To Prevent Fish Kill:
  • Follow this procedure anytime system has been shut off for an extended period of time. Day 1: Run system for 30 minutes; turn system off for remainder of day.
  • Day 2: Run system for 1 hour; turn system off for remainder of day.
  • Day 3: Run system for 2 hours; turn system off for remainder of day.
  • Day 4: Run system for 4 hours; turn system off for remainder of day.
  • Day 5: Run system for 8 hours; turn system off for remainder of day.
  • Day 6: Run system for 16 hours; turn system off for remainder of day.
  • Day 7: Begin running system 24 hours/day, 7 days/week.

Summer Operation
To reduce the risk of fish kills in hot summer months and for optimum aeration benefits, Airmax Aeration Systems should run continuously throughout
the summer.

Winter Operation

• Owner assumes all responsibility for operating Airmax Aeration Systems during winter months. Operating in freezing conditions on an ice-covered pond will cause large open water areas at diffuser sites. Ice thickness around open areas will be much thinner than the sur-rounding areas. Airmax strongly recommends that “Danger – Thin Ice” be posted at frequent intervals around pond.
• If operating during the winter season, condensation could cause airlines to freeze. If so:
  • Determine which ball valve controls the airline containing the blockage.
  • Turn off power at the external switch, then disconnect the quick connect fitting between the compressor and airflow manifold assembly. Close all valves except for the one with the blockage.
  • Pour 1 cup of isopropyl alcohol into the flex tube on the manifold, attach and tighten the quick connect, then turn the system on and allow it to run until airline is free of ice.
  • Note: You may have to repeat the process if some airlines do not thaw out condensation on the first attempt.
• If you choose to turn your system off for the winter, follow the steps below:
  • Turn the external shut off switch to the off position.
  • Open cabinet lid and unthread quick connect fitting on one compressor exhaust port leaving the flex tube connected to the airflow manifold.
  • Remove the four 7/16” nuts that secure the compressor mounting brackets to the cabinet base.
  • Unplug and remove the compressor. Repeat procedure for second compressor.
  • Store compressors in a clean, dry location.
    Note: We recommend threading the nuts back onto the mounting studs to prevent misplacing hardware.

Maintenance

• Airmax Aeration Systems are designed for low-maintenance and require minimal scheduled maintenance. Cabinet inlets and outlets should be kept free of debris and weed growth allowing normal ventilation.
  • 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 or when compressor, power control, compressor fan, or other electrical components are producing unusual noises or odors.
  • Always use parts that are supplied or approved by Airmax, Inc. Use of other parts may result in poor performance and could create a hazardous situation.
• **Local environmental conditions may require more frequent maintenance.
• 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.
• EVERY 3-6 MONTHS – Air Filter: Clean/replace air filter.
• Cooling Fan: Check to ensure that cooling fan is operating. Cool air should be pulled in through filter media and blowing over compressors, moving hot air out through louvered vents.
• Pressure Gauge: Mark pressure gauge upon initial start up. Check to verify pressure has not significantly risen above or dropped below initial reading. Typical operation will range between 5 and 15 PSI depending on depth.
• Pressure Relief Valve: Check to ensure air is not escaping from valve and replace if needed.
• EVERY 12-18 MONTHS – Maintenance Kit: It is recommended to install a maintenance kit every 12-18 months to ensure optimum performance.
• EVERY 24-36 MONTHS – Membrane Sticks: We recommend inspecting and/or cleaning the membrane diffuser sticks every 24-36 months, especially anytime the pressure gauge reading is significantly higher than normal or if there is a reduction of bubbles from the diffuser. To clean, use Airmax D-Scale™ (#530298) and a soft cloth.
