Drain tank volume
The volume of the drain tank provided in the installation.
The larger volume, on the one hand, allows for better flushing, on the other - affects the water consumption and tank dimensions. In addition, with relatively small bowls, it does not require much water. Most installations use tanks of 6 to 10 liters - these indicators are considered optimal in the light of the described features.
Mount height
Mount height in this case is called the total height of the assembled installation, from the top to the bottom point. This is the minimum vertical space that is required to install the structure. Many models have adjustable legs to adjust the height within 100 - 200 mm; for such cases, the minimum height of the structure is specified.
Mount depth
Mount depth - the total depth (thickness) of the structure in the assembled form. This will determine the thickness of the decorative box and/or the depth of the niche in the wall - depending on how it is planned to mount the installation. In some models, the mounting depth can be adjusted.
Max. load
The greatest weight of the user, which is able to withstand installation (of course, provided that it is high-quality installation). Indicated only for models used with toilet bowls and bidet (cf. «Purpose»). Note that even the most modest models can withstand about 300 kg, and in most cases this indicator is 400 kg and higher - this is more than enough for full use.
An individual case is a block model (cf. «Type of construction»): in them weight may be limited to the possibilities of outdoor plumbing.
