Information about this operating manual
Please read the operating instructions and familiarise yourself with the unit prior to using it for the first time. Adhere to
the safety information for the correct and safe use of the unit.
Please keep these operating instructions in a safe place! Also hand over the operating instructions when passing the
unit on to a new owner. Ensure that all work with this unit is only carried out in accordance with these instructions.
Use
The aerator Aqua Air 250 LM enriches the water with vital oxygen to decompose contaminants resulting from exces-
sive nutrients, such as ammonia/ammoniac or nitrite. Via a bypass (injector), the water flow at the pump outlet creates
a vacuum. The air taken in at this point mixes with the outflowing pond water. When used in combination with the
OASE products Bacto Plus LM and/or Ground Clear LM, the cleaning process is notably increased by the targeted
colonisation of micro-organisms requiring oxygen. Aqua Air 250 LM is recommended for a maximum water volume of
250 m³.

Intended use

The aerator AquaAir 250 LM, in the following text termed unit, may only be used to enrich normal pond water with air at
a water temperature of +40 to +95 degrees Fahrenheit. Do not use the unit in swimming ponds.

Safety Instructions

− Check that the electrical data of the power supply network and that on the type plate coincide.
− Only connect the pump to a grounded power outlet (GFI) in accordance with the valid local or national
electrical codes (NEC, UL, CSA, IEC...). Contact a qualified electrician with any questions.
− Do not use additional components, extension or connection cables or adapters, which are not grounded.
− Never operate the pump while people are in the water.
− Make sure that garden ponds meet the local and national installation regulations. Contact a qualified
electrician!
− Remove the power cable from the electrical socket prior to handling the pump.
− Never carry or pull the pump by the power cord.
− Always keep the connection points (power plug) dry.
− Do not operate the pump if cable or casing shows any signs of damage.
− Lay the connection cable such that it is protected against possible damage.
− To avoid potentially dangerous situations, only the manufacturer is allowed to make repairs or cable
replacements.
CAUTION: This pump is for garden use. Do not use in swimming pools, spas, hot tubs, etc. Running dry will inevitably
cause almost immediate failure and void all warranties implied or otherwise.

Electrical Requirements

WARNING: OASE pumps MUST be connected to a properly grounded and GFCI (Ground Fault Circuit Interrupter
< 30mA) protected 110-120 Volt AC circuit only. If the electrical cord provided is not sufficient we suggest that you
consult a certified electrician and have them install an additional GFCI outlet within reach of the cord. Consult your
local power authority for electrical codes or requirements. Avoid excessive flexing of or abrasion to the electrical cord.
Any alteration to an OASE pump will result in non-compliance with UL listings and requirements. In such instances all
warranties implied or otherwise are deemed immediately void.
WARNING
Risk of electric shock - This pump is supplied with a grounding conductor and grounding-type attachment
plug. To reduce the risk of electric shock, be certain that it is connected only to a properly grounded, ground-
ing-type receptacle.
Do's
− Do disconnect the plug from the receptacle before moving or cleaning the pump.
− Do disconnect the plug from the receptacle before entering the water area.
− Do have all electrical outlets installed and serviced by a licensed electrician.
− Do disconnect the pump from the electrical outlet at the first sign of any problem.
