4 Dimensioning and planning 4 Dimensioning and planning The SolexMega-Kaskade is a solar transfer station used to transfer the heat from the primary or solar circuit to the secondary or storage tank circuit. The cascade will only work flawlessly if the installation meets certain requirements. Please take some time to plan the installation. -
Page 13: Assembly And Installation
5 Assembly and installation 5 Assembly and installation During operation, the access to the control and safety equipment must be guaranteed at all time! The discharge lines of the pressure relief valves must be conducted into heat-resistant collecting containers of corresponding size. Thus, an uncontrolled discharging into the environment is avoided and the refilling of the circuits is facilitated! NOTICE Material damage due to high temperatures! - Page 14 5 Assembly and installation Top view 1. Determine the mounting location of the transfer station near the buffer tank. In long pipes, the transmission performance may be reduced due to higher pressure losses. 2. Remove the packaging. 3. Take the stations off the pallet. 4.
- Page 15 5 Assembly and installation 9. In order to prevent damage at the safety group, it is mounted in the modules at the factory. Commission the safety group as follows: a. Unscrew the pipe at the connecting T-piece [1] of the solar return. b.
