by a company (person) authorised to such activity.

(protector).
•
The degree of protection of electric parts of the heater is IP 42.
2.5 CONNECTION OF INDIRECT HEATER TO HOT WATER SYSTEM
It is recommended to install stop valves on the heating water inlet and outlet (for possible
dismantling of the heater).The valves have to be as close to the heater as possible to avoid
higher thermal losses (Figure 4, Figure 5, Figure 7 and Figure 8).
