Reference Standard: EN 60.335.1. |
|
and following standards: |
• 2004/108/EC Electromagnetic Compatibility Directive |

2 Safety instructions and recommendations
2.1 Safety instructions
Any work on the installation must be done by a qualified professional in compliance with the codes of practice and according to the instructions provided.
2.2 Recommendations
Have the installation regularly serviced to guarantee that it operates correctly over time.
It is essential to check the magnesium anode in the DHW tank and the installation and heat transporting fluid pressure every two years.
Never cut the power to the solar control system, even during extended absences. The control system protects the installation against overheating in summer when it is running.
During extended absences, we recommend lowering the set point temperature in the solar DHW calorifier to 50°C. When the user is present, the set point must be set to 60°C.
Never drain the installation. Do not replace or add water or solar fluid to the installation. These actions must be carried out by a qualified technician.
Do not modify the control system parameters unless fully conversant with them.

Composition of the NF CESI DIETRISOL TRIO solar systems packages (for France only)
Check the composition of the CESI solar system, which complies with the requirements of the NF CESI mark, using the table below. The references and packages listed must be shown on the invoice for the system sold by the installer.
A system is complete and functional according to the NF CESI mark if all system references appear on the invoice.
The system is composed of the following elements:
•A collector field with 1 or 2 solar collectors.
•A solar domestic hot water tank to which a solar station incorporating a heating pump, an expansion vessel and a Diemasol A control system is to be mounted.
•The solar fluid that protects the installation from frost and
corrosion.
The system is delivered to the installer in two units: a roof pack containing the collectors, their mounting system and the hydraulic connections on the one hand, and a cellar pack containing the calorifier, the system components and the solar fluid on the other hand.

3.2 Main parts
Dietrisol TRIO DT ... is a high performance solar DHW tank/calorifier designed to be connected to Dietrisol NEO or POWER solar collectors and an De Dietrich central heating boiler.
It is designed in such a way as to be able to cope with a solar collector surface area of up to 4.5 m2 (DT 250) and 6.5 m2 (DT 350) under the conditions set out in the chapter "Hydraulic Connection Primary Solar Circuit".
tank
The high quality steel tank is lined with food standard quality vitrified enamel, which protects it from corrosion and preserves all the qualities of the domestic water.
The Dietrisol TRIO DT ... tank is fitted with 2 heat exchangers per zone for solar heating and one heat exchanger for supplementary heating by means of a fuel oil or gas boiler.

Protection against corrosion
The tank is also protected from corrosion by two magnesium anodes which must be inspected every 2 years and replaced if necessary.
Heat exchanger
The thermal exchanger welded into the tank is made of smooth piping, the inside of which, which is in contact with the domestic water, is enamelled.
Insulation
The tank is strongly insulated with high strength rigid polyurethane foam with no chlorofluorocarbons (CFC), 50 mm thick to minimise heat loss.
Casing
The outside casing is made of painted steel sheeting. The top and side covers are made of ABS.
Solar station
The solar heating pump unit comprises the solar circuit safety unit, a pressure and temperature gauge and a flowmeter to visualise circulation of the solar fluid between the panels and the DHW tank. An expansion vessel is connected to the solar unit; it is used to compensate for the expansion of the solar fluid in which the temperature varies between 0 and 150°C.
Diemasol B regulator
The control system is the solar system's brain; it makes the solar heating pump run at variable speeds according to the difference in temperature between the bottom of the DHW tank and the solar panels. The control system manages the set point temperature (temperature to be attained in the DHW tank), overheating and nighttime cooling. The control system also displays the various operating modes, the temperatures in the collectors and in the bottom of the DHW tank, as well as signalling any malfunctions.
