| The sliding mechanism and the watertightness system operates perfectly on condition the window is installed professionally. |
| Please note that due to the high watertightness offered by protection rating IP 66, condensation may form inside the device. |
| Cement is the most costly ingredient and is held to the minimum consistent with desired strength and watertightness. |
| Openings and passageways shall not adversely affect the watertightness of bulkheads. |
| The standard tests for cells, including those for watertightness, are set by a body called the International Electrotechnical Commission. |
| Neoprene seals ensure the watertightness between the water boxes and the end plates. |
