The denomination of the water fittings refers to a theoretical system configuration. See page 19. r 7200 Kombisolar 3S combination storage cylinders are delivered without a filling pump. A suitably rated pump must be provided and installed separately. For further information on the recommended solar heating circuit flow rate, see the installation instructions for the water outlet and return kit.
7200 Kombisolar 3S combination storage cylin- ders are delivered in a single package consisting of a triple wall cardboard box (7200 Kombisolar 3S 430-550) or a plastic bag (7200 Kombisolar 3S 750-1000) on a wooden pallet. 7200 Kombisolar 3S...
Handling HANDLING The storage cylinder, complete with pallet, must be moved using a fork lift of suitable lifting capacity. Proceed as follows to remove the storage cylinder from the pallet. - Remove the brackets (1) - Place a platform of about half the height of the pallet near the storage cylinder.

The casing and insulation can be removed to facilitate access into the place of installation. To do so, proceed as follows. - Remove the plug (2). Unscrew the two fixing screws and remove the top insulation section (3). - Remove the protective fitting plugs (4). - Unzip the plastic cover (5).
Place of installation PLACE OF INSTALLATION r 7200 Kombisolar 3S combination storage cylin- ders can be installed in any room where there is no spe- cific requirement for an electrical protection rating higher than IP X0D. Respect the minimum specified installation distan- ces to ensure correct installation and access for maintenance.
Water connections WATER CONNECTIONS r 7200 Kombisolar 3S combination storage cylinders can be connected to even previously installed hot water gene- rators provided they are of adequate output power, but care must be taken to ensure correct water flow directions. They can also be easily integrated in r solar heating systems.

The domestic hot water tank must be filled and The lower the temperature of the heating return pressurised before the inertial storage cylinder (<40°C), the greater the efficiency of the solar hea- is filled. ting system. In very hard water areas, use suitably treated water Make sure that all components chosen for use with to fill the inertial storage cylinder.
Location of probes LOCATION OF PROBES r 7200 Kombisolar 3S combination storage cylinders incorporate probe wells for fitting the solar controller and boi- ler probes. Make sure that these probes are inserted all the way. Installers are responsible for all connections to the boiler or hot water generator. Installers must ensure proper installation and functioning in compliance with all applicable legislation.
Initial start-up INITIAL START-UP Heat is only transferred from the solar heating circuit to the combination storage cylinder when the temperature of the solar collectors exceeds that in the combination storage cylinder. It is therefore temperature differential rather than absolute temperature that is important in con- trolling solar water heating systems.
Heating circuit - Check that the heating circuit has been properly bled Provided all the above checks have been completed successfully, re-start the boiler and the storage cylinder and check the temperature settings and domestic hot water draw rate. Preparing for extended periods of disuse PREPARING FOR EXTENDED PERIODS OF DISUSE If the combination storage cylinder is not going to be used for an extended period of time, prepare it for shut-...
Maintenance MAINTENANCE Scheduled maintenance is essential for the safety, efficiency and long working life of your combination storage cylinder. Proper maintenance also ensures reliability over time. Have your combination storage cylinder serviced either by a r Technical Assistance Centre or by a qualified professional once a year. Perform the following operations before beginning any maintenance: - Switch the electricity supply to the storage cylinder’s...
