1. Remove the device from the box and check whether the device
is damaged while transportation. In case of damage please contact
your dealer and do not install the device.
2. Check the content of the box (See Scope of delivery).
3. Place the device in the place where it will work permanently (this
is important in order to be provided the length of the hose from
device to aquarium). If the device will be mounted on the wall use
Annex 1 - Stencil for wall fix (See Scope of delivery). The ARKA
device have to be placed at the level of the upper edge of the
aquarium or a maximum distance of 80 cm below it. The bottom of
the bottles/canister with liquid should be above the ARKA device or at
a maximum distance of 40 cm below it (Figure 1). Do not place device
above the edge of the tank if the device is with disabled function Back
Flushing.
Note: We recommend ARKA device to work with function
Back Flushing On (function Back Flushing is on by default) to avoid
fluid leaking out from the bottle into the aquarium.
