2. FOR THE INSTALLER
2.1 Installation
A qualified, competent installer must install the hot water storage tanks in accordance

Location needs to be chosen to prevent damage in case of tank leakage (e.g. place tank in
a drain pan or near a floor drain of sufficient capacity). For mounting of the jacket see
separate attached Kit installation sheet.

working pressure is 7 bars. A typical installation diagram for an un-vented installation is
