2.1.2.5 Connect the EH (no. 1, Fig. 7) using a flexible hose (no. 3 Fig. 7) to the water supply system
(no. 6, Fig. 7) or storage tank (no. 5, Fig. 7) in an adjacent room. We recommend to install the storage
tank at the height of at least 1 m from the EH top. Before the EH, a shutoff valve (no. 4, Fig. 7) shall
be installed. Install the water drain valve (no. 2, Fig. 7) using a flexible piping of a required length.
To prevent lime deposits, the water hardness shall be 0.5° to 5°F. We recommend to use a special
demineralization unit (reverse osmosis).
ATTENTION!
For the EH connection to the water supply system, do not use branch pipes, fittings
and other piping elements made of galvanized steel.
