* Weight shown is a guideline only . ** The length and width dimensions are the same as for the standard unit . *** When delivered , the standard pre-inflation of the tanks is not necessary the optimal value for the system . To permit changing the water volume , change the inflation pressure to a pressure that is close to the static head of the system . Fill the system with water ( purging the air ) to a pressure value that is 10 to 20 kPa higher than the pressure in the tank .
Electrical data , options 116T , 270T
The original pumps that are factory-installed in these units have motors with efficiency class IE2 . The additional electrical data required by regulation 640 / 2009 are given in the installation , operation and maintenance instructions .
This regulation regards the application of directive 2005 / 32 / CE on the eco-design requirements for electric motors .
