4. Service Space

There is enough room for installation and maintenance.

The outlet and the inlet are not impeded, and the influence of external air is the least.

The air flow can reach throughout the room.

The connecting pipe and drainpipe could be extracted out easily.

There is no direct radiation from heaters.

Additionally, it is required to keep 20mm between the rear and wall,1700mm vertical distance between

the top of unit(outlet) and the upper obstacle.
