Lotus Oxygen Concentrator Add-On
Please review the owner’s manual for installation and operations for your Lotus unit. This addendum details
steps for connecting and using the O2 conversion kit + O2 concentrator.
The oxygen generator adaptor kit allows for utilizing an oxygen generator as the oxygen source. The kit has safety
features built into it to allow for turning the oxygen generator off when the Lotus unit is shut down. It also repressurizes
the oxygen to the required operating pressure. Moleaer recommends industrial-grade oxygen generators to be used with
the Lotus. The recommended oxygen generator flows and pressures are provided in the table below.

Installation
Locate the oxygen generator in a well-ventilated area that is protected from weather elements and remains between 41°F
to 104°F (5°C to 40°C),15–90% humidity. Any outdoor installation without proper protection of the oxygen generator voids
the manufacturer's warranty. Please contact your Moleaer representative for outdoor installation suggestions.

Startup Instructions
NOTE: For all tube connections use the supplied tube clamps to assure the connections are leak tight.
1. Pump prime check: Make sure your Lotus unit is fully installed and the pump is primed properly. Refer to this
manual for installation and startup instructions. After this step, turn off the Lotus unit and proceed to the next step.
2. Power compatibility check: Make sure the power requirements of the oxygen generator match your oxygen
conversion kit box. The oxygen conversion box comes in 120VAC/60Hz or 230/50Hz versions. The oxygen
generator and the oxygen conversion box must have the same power ratings.
3. Oxygen generator independent flow adjustment: Unbox the oxygen generator and power it up by connecting it
to a power outlet. Turn on the oxygen generator and allow it to fully start (about 1 minute). Adjust the flow to 5lpm
on the flowmeter. Make sure the oxygen generator is functioning properly and there are no alarms (red LED).
Refer to the oxygen generator manual for troubleshooting if needed. Once the flow is adjusted, do not readjust the
flow unless you follow the procedure described in this step. Use a marker or an indicator if needed to remember
the position of the knob.
4. Turn off the oxygen generator and disconnect it from the power outlet.
5. Unbox the oxygen generator conversion box. The box can be magnetically mounted on the Lotus enclosure.
6. Connect the oxygen generator’s power cord to the female cord of the oxygen conversion box.
7. Connect the gas tubing of the oxygen outlet of the oxygen generator to the port labeled
8. Connect the second gas tubing to the outlet of the oxygen conversion box and the oxygen inlet port on the Lotus
unit labeled
9. Connect the Oxygen generator’s auxiliary cable to the auxiliary port on the Lotus unit labeled
10. Connect the power cord of the oxygen conversion box to a power AC outlet labeled
11. Your Lotus unit and the box can use the same or separate power outlets.
NOTE: Make sure the power outlet matches the specifications on the box. The oxygen conversion box comes in
120VAC/60Hz and 230VAC/50Hz versions. The Oxygen generator consumes about 6 amps at 120VAC and 3 amps
at 230VAC.
12. Check the oxygen conversion box power: Turn on the Lotus unit and check the LED light on the oxygen
conversion box. The LED light green light is located on top of the box and it must be on when the unit is powered.
NOTE: The oxygen generator does not turn on immediately after the unit is powered on but the LED light on the
conversion box powers on immediately.
NOTE: The oxygen generator may run at a lower flow than what was adjusted in step 3. Do not readjust the
flowmeter knob to increase the flow. This will result in overdrawing the oxygen and may damage the oxygen
generator. Follow step 13 for the nanobubble generator’s flow adjustment.

13. Once the pump is fully primed, the water pressure will go up and the oxygen generator will turn on. With a 5-10
second delay, the gas pressure (as indicated on the Lotus pressure gauge) will start going up.
14. Visually check bubbles from the outlet of the Lotus unit (located in water) to make sure bubbles are coming out of
the unit.
NOTE: Large bubbles are the by-products of the nanobubble generator. Therefore, there are always visible
bubbles discharged from the unit.
15. For further gas flow adjustment, use the rotameter’s knob inside the Lotus unit.
Maintenance
Check the outlet flow of the oxygen generator by disconnecting the oxygen tube once every two weeks. When the tube is
disconnected, the oxygen generator’s flowmeter should go up to 5 lpm.
Troubleshooting Guide

•Leaks
•Lotus rotameter knob is closed
•Damage to the oxygen generator
•Use soap water to check for leaks while the unit is
running.
•Turn the rotameter knob counterclockwise to allow
more gas into the nanobubble generator.
•Check the oxygen generator’s manufacturer
