DANGER

Explosion hazard through potentially explosive atmosphere in the collection tank!

There can be an explosive atmosphere in the collection tank. During maintenance work, there is a risk of explosion. Follow these points:

1. A potentially explosive atmosphere, zone 2, applies in a 1 m radius around the ventilation pipe. Obey the factory regulations.
2. During maintenance work, make sure that the air will change eight (8) times each hour in the operating space.

Maintenance and repair work can only be done by a qualified staff (e.g. customer service). Obey EN 12056‑4 for the maintenance intervals:

• ¼ year for commercial operations
• ½ year for multi-residential buildings
• One year for detached houses

After ¼ year

• Visual inspection of the inlet pipe, clean it if necessary.

After ½ year

• Examine the connections for impermeability.
• Clean the collection tank and overflow channel. If overflows occur regularly, then make sure to clean the overflow channel monthly.

After 1 year

• Clean the solids separation tanks and screens.

After 2 years

• Change the oil of the sewage pump. If using a pencil electrode for sealing chamber monitoring, change the oil in the sealing chamber according to the display.

Write all maintenance and repair work in a log. The log must be signed by the qualified staff and the operator.

Do a test run after the maintenance work.
