Warnings - SOLE EUROSTAR ECO Series Installation & User Manual

3. Warnings

Before starting installation, the installer should read and observe carefully the following warnings in order to
avoid danger of death, injury or property damages.
3.1. You may elevate on roof the parts of the solar system, ONLY when an internal staircase of enough
width, exists in the building reaching the roof. Otherwise you must use a proper CRANE to elevate the parts.
It is not allowed to stand at the edge of any roof (flat or inclined) and pull by ropes any part. DANGER OF
DEATH.
3.2 The collectors have a large surface exposed to wind. NEVER install a system with strong winds. Choose
a calm day. DANGER OF DEATH or heavy injury.
3.3. If the installation will be on an inclined roof (tiles), there is danger of slipping. Use always SAFETY
BELTS (securely fastened) from a higher position of roof. DANGER OF DEATH.
3.4. After completion of the installation make sure that all bolts and nuts are fastened well and the whole
system is securely fastened to the roof. The support system can withstand air velocities up to 97,2 km/hr.
Make sure that the fastening on roof can withstand as well at least same air velocity. DANGER OF DEATH.
3.5. Frequently some parts of the support systems have sharp edges. Use always gloves when you are
handling the support system, in order to avoid danger of injuring the hands. DANGER OF INJURY.
o
3.6. The collectors when exposed to solar irradiation during installation get very hot; above 120 C in 2-3
minutes. There is danger of burning the hands when touching the copper piping outlets. You must leave the
carton package cover ON the glass until completion of the installation, or you must use thermo resistance
gloves. DANGER OF INJURY.
3.7. If you are using hands to position the tank on the support system at least 2 people are needed for
systems 120-150.
It is preferred to use a crane. In this case make sure that the pulling belts are on each side between the
piping outlets of the boiler so that it cannot slip.
3.8. In cases where the solar system is large and the hot water consumption is low, the hot water in the solar
o
tank may reach temperatures up to 90 C. In this case there is danger of burns for the user, especially for
children.
o
It is strongly recommended to install a thermostatic mixing valve set at 55 C anywhere at the hot supply
piping and before the hot outlets of the building (before taps, showers, e.t.c.)
3.9. If the solar system is equipped with the (optional) electric immersion heater, the electrical connection
should be done by a fully licensed electrician following the national rules for electric installation.
The immersion heater is single phase 230 Volt of 2kW or 3 kW or 4 kW power.
There is an "earth point" on the flange of the heater which must be connected to the central "earth" of the
2
building. In any case the support of the solar system must be "earthed" with copper wire of 16 mm to the
earthing grid of the building. This will also serve as lightning protection.
3.10 In a solar system equipped with the optional electric heater, after completion of electrical and plumbing
installation test the operation of the electric heater and thermostat, ONLY AFTER FILLING the tank with city
water. Otherwise the electric heater will be fused out. (destroyed)
3.11 Make sure that before filling the tank with city water the pressure safety non-return valve has been
installed on the cold water inlet with the arrow pointing to the tank. This valve will open and release the
pressure when by overheating or other reason it has exceeded 10 bar.
3.12. When handling the thermo-convention liquid make sure that you wear protective glasses for the eyes
and gloves for the skin.
3.13. When temporarily leave the collectors on the roof during installation ALWAYS position them with glass
facing the sky. Otherwise there is danger that water from rain may enter the collector from the back side
through the ventilation holes. If this happens the insulation will be wet and the glass will have humidity on
inside surface. Drying will take a very long time.
