3. Remove the magnetic side panel and the air lter.
4. Remove the G1/4” plug located on the lling port with a hex wrench.
5. Carefully pour the coolant into the lling port until it reaches the level
mark. No coolant must be spilt inside the device!
6. Close the G1/4” plug with a hex wrench and place OTTO in its normal
position.
7. Switch OTTO ON to let the coolant circulate through the system.
8. Switch OTTO OFF again fast enough so the system is not overheated
(after 10-15 seconds or when the reservoir is 2/3 full).
9. Put OTTO on its left side.
10. Remove the G1/4” plug located on the lling port with a hex wrench.
11. Carefully pour the coolant into the lling port until it reaches the level
again. No coolant must be spilt inside the device!
12. Close the G1/4” plug with a hex wrench and place OTTO in its normal

13. Switch OTTO ON.
14. Lift up the fore part of OTTO at 40-45º to release air.
15. Repeat relling until the reservoir and liquid system are full to the level
mark. ATTENTION: there should be some air in the system to let warm
coolant swell out.
16. Put on the air lter and the magnetic side panel when OTTO is lled
with coolant. Now you can use OTTO.
Always use only specially prepared coolant or distilled water with the ad-
dition of an additive for liquid cooling circuits according to the instructions.

cooling. This is the transformation
we use at Comino for assembling
our systems. It works best for liquid
cooling.
• +18mm Transformation
Is designed for liquid-, air-
and hybrid systems.
It’s possible to install 2х120
or 2х140мм AIO on the CPU.
• +54mm Transformation
Is designed for air or hybrid systems.
It’s possible to install 1х120mm
radiator with an AIO.
