Introduction And General Operation 1. Introduction and general operation The system with Clivet thermal solar collectors must be professionally installed by qualified installers in full compliance with the hydraulic and wiring diagrams. For correct operation of the system, the instructions enclosed with each individual element supplied (e.g.
Page 7: Requirements And Pre-Installation
Requirements And Pre-installation 2. Requirements and pre-installation 2.1 Orientation of collectors For optimal performance, the solar collector must face SOUTH. A deviation of 15-20° is acceptable; deviations over 20° require compensation by increasing the surface area of the solar park. Collectors do not catch the sun’s rays Increasing the surface area Surface area almost doubled compared to south-facing...
Page 8: Positioning Of Collectors
Requirements And Pre-installation 60° 90° 90° 90° 45° 30° Summer Solar panel Mid-season (excellent compromise) Winter 2.3 Positioning of collectors Solar collectors can be installed in various positions on the roof or around the house and in different configurations, following the instructions in the previous chapters. It is important to ensure that the collector receives the sun’s rays without interference from neighbouring trees and bu- ildings even in the worst conditions (winter), otherwise the lack of sunlight will have to be compensated for by increa- sing the surface area of the collectors.
Page 9: Sizing Of The System
Requirements And Pre-installation If there are several rows of solar collectors, make sure they do not shade each other and follow the design guidelines (see example below). Examples: Shade between rows with cr 120 mod. Vertical panel installed at 45° (calculation referring to the city of verona) Shade between rows with cr 120 mod.

Page 29: Orientation And Spacing
Orientation And Spacing 7. Orientation and spacing 7.1 Orientation of collectors For the Northern Hemisphere, the ideal orientation is the geographic south. In many cases, especially for the pro- duction of domestic hot water, orientation is often preferred facing south-south-west (green band), as the energy is more useful for peak loads during the day.

Page 89 Connections Based On The System COOL In this menu, the parameters are set to activate 3 cooling functions: system cooling (OSYC), tank cooling (OSTC), heat dissipation on a heat sink. The system cooling function (OSYC) enables energy to continue to be stored in the tank beyond the maximum tem- perature value set in parameter SMX (and in any case not more than 95 °C), thus allowing overheating to be dissipated from the collectors until the limit temperature stored in parameter CEM has been reached on the panel or the limit temperature of 95 °C has been reached in the tank.
Page 90 Connections Based On The System OTDI In this menu, the thermal disinfection function is activated, which starts the additional heating (relay HR) on the boiler to help prevent Legionella in the domestic hot water tank. Activation of this function ensures that at the end of the monitoring period (PDIS), the disinfection temperature (TDIS) is reached continuously, without interruption, during the disinfection phase (DDIS).

Connections Based On The System 14.11 Troubleshooting Protection against problems When there is a break or short circuit to the temperature probes, the controller disables the outputs and the error sym- is displayed at the same time. If the controller does not work properly, carry out these checks: Press the +/- buttons to check the error code, the symbol is displayed.
Page 93 Connections Based On The System Meaning of the symbols The controller is a quality product, designed for continuous, problem-free use for many years. Very often the cause of problems does not lie within the controller but in external devices or events. The table below should help to identify and solve the problem as quickly as possible.
Page 94: Start-Up
Start-up 15. Start-up 15.1 Cleaning the solar circuit The two taps in the solar unit are used for cleaning and filling, one for filling and the other for draining, separated by a shut-off valve. For better operation, try to position the taps in the solar unit at the lowest point of the system. If neces- sary, add a 3rd tap at the lowest point of the system, which shall be used to completely drain the system.
Page 95: Checking The Tightness And Emptying
Start-up 15.2 Checking the tightness and emptying Checking the tightness Finish the rinsing phase by closing the tap (3). Raise the pressure inside the solar circuit to reach a high pressure, which should be higher than the operating pressure (see next page) and no more than 0.2 bar less than the pressure relief valve setting (e.g.
Page 96: Antifreeze And Charging Pressure
Start-up 15.3 Antifreeze and charging pressure % Before filling the circuit, check the pre-charging pressure of the expansion tank with a pressure gauge or with a bicycle pump, which must be about 0.3 bar less than the cold charging pressure of the system. If antifreeze is to be used, the water and glycol must be mixed in a container before being charged into the system.
Page 97: Filling The Solar Circuit
Start-up 15.4 Filling the solar circuit The operations must be carried out when the system is cold (early morning) or alternatively by covering the col- lectors (e.g. with its packaging box). • Open the taps (1) and (3) and close the shut-off valve (2).

Maintenance 16. Maintenance Summary table The systems are highly reliable and require only minimal maintenance over the years. These instructions should be followed: When Operations to be performed EVERY YEAR Check that the percentage of glycol in the mixture is not below freezing point using the refractometer; top up if necessary.
Page 100 Maintenance Caution!!! Checking the magnesium anode For the warranty to be valid, the magnesium anode must be checked annually and replaced when worn. In areas with particularly hard water, it can happen that a layer of limescale forms on the anode, preventing it from wor- king normally and effectively rendering its protection useless.
