4 When installing the remaining components eg. Solar collectors, pumps and geysers, be sure to follow the appropriate installation instructions provided by each manufacturer. Users Installation, maintenance and dismantling may only be performed by trained personnel in accordance with this INSTRUCTION MANUAL and safety instructions. Trained personnel must be familiar with this MANUAL . Use the GEYSERWISE only after first thoroughly reading and understanding this INSTRUCTION MANUAL and the safety instructions. In the event of any ambiguities regarding the installation and operation, consult trained personnel or contact our offices. 3 SAFETY Proper Usage The GEYSERWISE may only be used for systems within the permissible ambient conditions Improper usage The GEYSERWISE must not be operated in the following environments.

5 Outdoors 2 In damp rooms In rooms in which the operation of electrical and electronic components may be dangerous Dangers during Installation The following dangers exist during installation of the GEYSERWISE and during operation (in case of incorrect installation) Risk of death by electrocution Risk of fire due to short circuit Damage to any of the constructional fire safety measures present in the building due to incorrectly installed cables Damage to the GEYSERWISE and connected devices due to improper ambient conditions, inappropriate power supply and incorrect installation Therefore all safety regulations apply when working on the mains supply Be sure to comply with the specified degree of protection.

6 Factory labels and markings may not be altered, removed or rendered unreadable Before connecting the GEYSERWISE , make sure that the power supply matches the specifications on the type plate Make sure that all devices which are connected to the GEYSERWISE conform to the technical specifications of the GEYSERWISE All work on an open GEYSERWISE must be performed with the mains supply disconnected Protect the controller against overloading and short-circuiting Detecting Faults Check the display regularly In case of faults, isolate the cause As soon as it becomes evident that safe operation is no longer possible, remove the GEYSERWISE from the mains supply immediately Have trained personnel remedy the fault Exclusion of liability The manufacturer cannot monitor the compliance to this MANUAL as well as the conditions and methods during installation and operation.

7 Improper installation of the system may result in damage to the property and, as a result, in bodily injury. Therefore, we assume no responsibility for loss, damage or costs which result from or are in any way related to incorrect installation, improper operation, incorrect execution of installation work and incorrect usage and maintenance. The manufacturer reserves the right to make changes to the product, technical data or assembly and operating instructions without prior notice. 4 USES, CHARACTERISTICS AND TECHNICAL INFORMATION 3 Uses GEYSERWISE is designed to manage your hot water needs to your best advantage from both an energy and economical point of view.
