ELECTRIC CONNECTIONS

•
For the installation of the differential thermostat, refer the
producer's manual which is included in the package.
•
All of the units function with 230V / 50Hz.
•
In the case where an electric resistance is installed, the volt-
age must be checked. The electric resistances up to 4kW are
1~230 V with thermostat, while for the electric resistances
6kW - 9kW the voltage is 3~400V and the installation of a
thermostat is the installer's obligation.
•
The thermostat once installed and adjusted functions
automatically on the boiler. According to the needs of the
client, the temperature of the water can be adjusted by the
installer to lower or higher levels from the original
adjustment and between 30ºC - 80ºC. In the case that for
some reason the temperature exceeds the tolerated safety
level, the safety unit is activated. This is adjusted to be
activated when the temperature of the thermostat reaches
100ºC (±10). In the case that this happens, you must
determine its cause. After the water cools down, we can
reactivate it manually by pressing the red button.

Overheating

If your Solar Collector will be stagnant in the sun for an
extended period of time, you should cover the collector to
protect against overheating and damaging the collector and

Snow and Wind loads

Snow and wind loads are a significant factor for structural
planning. European norms were established, albeit without
specifically taking solar installations into account. Wind and
snow loads affect the collectors and the installation system.
Depending on the conditions and height of the installation site
as well as the collector inclination, the mechanical loads on
the system can vary considerably. Also see guidelines for the
planning of structural frameworks and standards EUROCODE
1, (European guidelines for structural planning). With combined
snow and wind loads the maximum strain for the solar collector

Lightning protection

This type of installation, do not increase the risk of attracting
lightning and there are no records of ever happened such inci-
dent. However we suggest that you check for a lightning rod
in your area and also check if it gives protection to the place
of your system. If it exists, and if it is not enough, we suggest
that you provide a lightning rod according to your country rules
and to EN 61024-1. We suggest that you connect the visible

• During the transport of the thermostats and during the
process of installation avoid the hitting / banging, dropping of
the thermostats, because they can cause serious damage to
the thermostat with very dangerous consequences to its
operation. The electric installation should be made by a
licensed electrician. A faulty electric connection can cause
an explosion of the boiler.
• In the case where the hot water consumption needs are
during periods of the day with little or no sunlight, for
instance after 17:00 or before 10:00 a.m., the use of a timer
is recommended. This will automatically activate the
electric resistance and as long as there is a need for hot
water.
• All the connections must conform with the regulations
(electrical, plumbing, urbanism and others) that apply in your
area.
after completing the installation of the system, clean the
area where you have worked , fill out the guarantee and
send it by registered post to Helioakmi S.a.

It is mandatory to follow best practice rules for static

Different codes and regulations apply in different countries
