Safety Information 

Before starting the installation job, it’s very important to read the entire instructions below. Make sure that you understand these in order to avoid potential hazards. Failure to do so may result in serious personal injury or damage to the equipment. 

Electric Shock 

• To reduce the risk of electric shock, connect only to a properly grounded, grounding-type receptacle. If in doubt, have the outlet checked by a qualified electrician.
• This unit is to be used in a circuit protected by a ground fault circuit interrupter (GFCI).
• Disconnect unit from power source before handling or maintenance.
• Do not attempt operate any electric part of this unit. Connect the power supply should be the only installation step that involved the electricity.

HQUA-PAS20 Pond Aeration System Safety Precautions 

• Keep the compressor ventilated, cool and dry.
• Do not allow anything to rest on the power cord.
• Never attempt any maintenance function that is not specified in the user manual.
• Never operate the system if unusual noises or odors are detected. Disconnect the power cord from the outlet and call for service

WARNING: This product must be grounded. In the event of an electrical short circuit, grounding reduces the risk of electric shock by providing an escape wire for the electric current. This product is equipped with a cord having a grounding wire with an appropriate grounding plug. The plug must be plugged into an outlet that is properly installed and grounded in accordance with all local codes and ordinances 

WARNING: Improper installation of the grounding plug is able to result in a risk of electric shock. When repair or replacement of the cord or plug is required, do not connect the grounding wire to either flat blade terminal. The wire with insulation having an outer surface that is green is the grounding wire. 

Check with a qualified electrician when the grounding instructions are not completely understood, or when in doubt as to whether the product is properly grounded. Do not modify the plug provided; if it does not fit the outlet, have the proper outlet installed by a qualified technician

Installation of HQUA-PAS20 Pond Aeration System

Tool Required

• Rake
• Shovel
• Boat/Raft/Swimsuit
• Phillips screwdriver
• 7/8” Wrench
• Coast Guard-approved life jacket

1. Find a place for the compressor to be ventilated and shelter from rain, sunshine, also less dust.

   

2. Screw the air filter into the compressor right near the pressure relief valve. Hand tighten only, use teflon tape if is needed.

   

3. Using your shovel, dig a trench from the shelter to the pond's edge. This trench should be a minimum depth of 8" to protect the airline. We recommend having utility lines marked before you begin digging. An extend airline might be needed for a long distance. We offer the conector kit for that.

   

4. Screw the conector kit on the airflow manifold with a 7/8" wrench. Use teflon tape if is in need.

   

5. Slide a hose clamp (HQUA-PAS2OHC) onto the airline and insert it into the connector kit (HQUA-PAS20CK01).

   

6. Using a phillips screw driver, secure the hose clamp onto the PVC airline.

   

7. Backfill the airline trench in a few areas to temporarily keep the airline in place until installation is complete.

8. Slide a hose clamp onto the airline from the other end. And insert it into the conector kit on the stainless steel base. Using a phillips screw driver, secure the hose clamp onto the PVC airline.

   

9. Screw the diffuser plate (HQUA-PAS20DP) on the stainless steel base. Hand tighten only, use teflone tape if is needed.  Make sure you have finished all diffusers' installation.

   

Final Step: Installing Diffusers from a Boat/Raft:  
Have one person on shore guiding the airline as a second person uses a boat or raft, extend the airline out to the area of the pond that the diffuser will be located. Gently release the diffuser into the water. Repeat until all diffusers are in position. Complete backfill on airline trenches and level with a rake. Complete installation by reviewing and following the Initial Start-Up Procedure in Section 2.4. 
Notice

1. Make sure your diffusers won’t get twined by any nets or fish line.
2. Make sure two diffusers are separated for equal water space to keep their best performance.

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.  We suggest the customer initial Start-Up procedure to prevent fish-kill No matter what kind of pond you have. Or anytime system has been shut-off for an extended period of time. 

Start-Up Procedure

1. Day 1: Run system for 30 minutes; turn system off for remainder of day. 
2. Day 2: Run system for 1 hour; turn system off for remainder of day. 
3. Day 3: Run system for 2 hours; turn system off for remainder of day. 
4. Day 4: Run system for 4 hours; turn system off for remainder of day. 
5. Day 5: Run system for 8 hours; turn system off for remainder of day. 
6. Day 6: Run system for 16 hours; turn system off for remainder of day. 
7. 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, HQUA PAS20 Aeration Systems should run continuously throughout the summer. 
Winter Operation 
Owner assumes all responsibility for operating HQUA PAS20 Aeration System 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 surrounding areas. HQUA strongly recommends that “Danger - Thin Ice” be posted at frequent intervals around pond. 
If you choose to turn your system off for the winter, do the following: 

• Disconnect compressor and the ariline.
• Cover airline ends with the caps or cloth to prevent debris from entering airline.
• If operating during the winter season, condensation could cause airlines to freeze. If so:
• Use 1 cup isopropyl alcohol in the airline running out to each diffuser plate.
• Turn on compressor to push through line and free any ice blockage.

The system includes a high-output air pump, a diffuser plate, and 100 feet of high-quality airline. The diffuser plate is designed to evenly distribute air throughout the pond, creating a uniform circulation pattern that helps to prevent stratification and promote healthy water quality. The air pump is both quiet and energy-efficient, using only 25 watts of power to operate. The system is also easy to install, with a simple plug-and-play design that requires no special tools or expertise.

Setup Guide

Setting up the HQUA HQUA-PAS20 Pond Aeration System is quick and easy. Simply place the diffuser plate in the desired location in your pond, attach the airline, and plug in the air pump. The system will begin working immediately, providing your pond with a steady supply of oxygen. It is recommended to place the diffuser plate in the deepest part of the pond to ensure maximum coverage. It is also recommended to clean the diffuser plate periodically to maintain optimal performance.

HQUA-PAS20 Pond Maintenance

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

1. Always unplug system before performing any maintenance or troubleshooting.
2. 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.

Notice: 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. 

Replacment Parts 

EVERY 3-6 MONTHS Air Filter: Clean/replace air filter HQUA-AF11. 
Pressure Relief Valve: Check to ensure air is not escaping from valve and replace if needed. 
EVERY 24-36 MONTHS  Membrane Sticks: We recommend inspecting and/or cleaning the membrane diffuser sticks every 24-36 months.
