Reef Octopus Model No.?

[willbratz]

Can anyone tell me what model number this may be? I looked on the pump and it's saying ( on the pump) that its a
Model: OPT-1000

I'm trying to find a manual for it, so I can figure out how to clean the pump.

Octopus NW 150.
To take the pump apart, twist the volute cover (the water intake cover) about 1/2 turn and it will come off and you can access the impeller.
