1. ElECTRICal HEaTING ElEMENT
1.1 general
The solar tank has an electrical heating element, only after
customer’s request. The electrical heating element can be
applied, only if it is allowed from the country’s laws and
from the environment of the installation place. When
allowed, heating element must respect local limitation of
power related to volume of the tank. The heating element
is installed at the tank’s flange, together with the safety
thermostat. The last one is set from the factory at 60°C.
At the same flange (with or without heating element) the
magnesium anode, is also placed.
1. The devices are in accordance with standards
ΕΝ60335-1 and ΕΝ60335-2-21.
2. All electrical connections must be made from
registered staff.
3. Even if the heating element is not connected to
the power supply, the ground cable must always
be connected to the ground or to the base.
4. Do not ever adjust the temperature of the thermostat
over 75°C.
5. Do not ever switch on the electrical heating element
with the tank empty; the damage will be large. In this
case, the guarantee of the company is not valid.
6. If the supply cord is damaged, it must be replaced by
the manufacturer, its service agent or similarly
qualified
persons in order to avoid a hazard.
