Wearing Parts - Oase AquaOxy 450 Instrucciones De Uso

Start-up
Prior to this observe the following operating steps: Connect the air hose to the unit prior to switching on. We recom-
mend to fit the aeration stones approx. 12 in. (30 cm) below the water surface. Keep the length of the air hoses as
short as possible. Protect the connection cable when burying and connect the transformer to a socket. Air will emerge
from the aeration stones after a short start-up time.
Cleaning
Attention! Dangerous electrical voltage.
Possible consequences: Death or severe injury.
Protective measures: Disconnect the power plug prior to reaching into the water and commencing
work.
Disconnect the power supply first, then secure the unit to prevent unintentional switching on. Should the performance
reduce, clean the air intake opening in the base of the housing.
Replacing the diaphragms
Diaphragms need to be replaced occasionally. Always replace diaphragms in pairs, left and right.
Disconnect the power supply first, then secure the unit to prevent unintentional switching on. Remove the hood by
unscrewing the screws from the unit underside (A). Disconnect the connection hose from the pump heads (B) on the
left-hand and right-hand side. Lift the motor block (C) and remove the diaphragm chamber (D) fitted with four screws.
The membrane can be replaced after loosening the screw and removing the support disk (E). Ensure correct insertion
(note the shape).
Reassemble the unit in the reverse order and put it back into operation.
