Operating instructions
(Figure 1, page 14)
Important: Do not immerse the air pump in water, protect it against flooding. Place the pump on
a firm surface above the water surface.
● Place the pump in an area that is protected against flooding.
● Make sure that the pump draws clean and pure air.
● Place the air pump on a flat level surface above the water level.
● Secure the air pump to prevent it from walking.
● Connect the rubber hose coupler to the pump outlet and secure it with the supplied hose clamp.
● Slide the other hose clamp over the rubber hose coupler.
● Connect the air distributor to the other side of the rubber hose coupler and secure it with the hose
clamp.
● Connect the air stones to the air diffuser with air hoses.
● Place the air stones in the water.
● If the air pump is properly installed and connected, it can be switched on by plugging in the power
plug.
Maintenance
(Figures page 14)
Regular maintenance:
● Turn off the air pump by unplugging the power cord from the electrical outlet.
● Regularly clean the foam filter (4): Unscrew the two screws (2) of the cover (3) and remove the
cover (3) of the casing (5). First, remove the caps (1) from the screws before the screws can be
loosened.
● If the foam filter (4) is dirty, take it out and clean it with air or replace it for a new foam filter (4).
● After cleaning, place everything back, fix the cover (3) with the two screws (2).
● If the air pump is properly installed and connected, it can be switched on by plugging in the power
plug.
To ensure a long life span and problem-free operation, we recommend that you check the pump
regularly for air capacity reduction by checking whether the air stones are producing enough air
bubbles.
● If the air capacity has decreased, check the air stones and replace, if necessary. Clogged air stones
will lead to low air pressure output in the pump and reduce the life of the diaphragms and pump.
● Switch off the air pump by unplugging the power cord from the electrical outlet before doing any
maintenance.
If replacement of the air stones does not improve the air capacity, check the air pump and replace the
membranes.
● Turn off the air pump by unplugging the power cord from the electrical outlet.
● Unscrew the four screws (6) of the pump housing (5) and remove the pump housing (5) of the
bottom plate (23).
● Remove the four screws from the motor flap (9) and remove the motor cap (9). (Note that the four
nuts (18) remain at their place).
● Lose one of the two motors (11) by removing the 2 screws (12).
