Basic Information Safety Notes Safety Notes The following notes and information are generally used in the operating instructions: L E Comply with information about function and operation. E Components and piping of the cooling circuit may never be used for transport. E Always comply with and observe all safety notes and safety information. Information about the operating instructions of the controller LOGON B WP The heat pump is fastened to the transport pallet.
Basic Information General General Usage Range The heat pump is designed only for heating as well as generating service water. The heat pump can be utilized in newly installed or existing heating systems by complying with the usage limits as defined by the AQUATOP planning document. E Setup The heat pumps can be set up on a smooth, level, and plane surface without the need of a base or pedestal. The installation room must be dry and frost-free. Rooms with much humidity such as laundry rooms, etc.
Basic Information Legal Guidelines, Rules, Warranty Terms, Receiving Inspection General Information These operating instructions serve the correct installation, adjustment, and maintenance of the equipment. The following information must therefore be read carefully and the heat pump must be installed, inspected, and maintained by correspondingly trained technicians. The manufacturer is not liable for mechanical, hydraulic, or electrical modifications after the warranty expires.

Installation and Connection Instructions Transport and Setup Transport Before every transport, make sure the lifting or transport equipment has the lifting power needed to transport the respective equipment weight. All of the tasks described here must be carried out based on the relevant safety standards. This applies to tasks associated with the equipment as well as the process or procedure of each task itself.
Installation and Connection Instructions Transport and Setup Hydraulic Connections After the unit is placed into position, make sure to check for visible damage. Properly dispose off the packaging material. Transport safety device The flexible connection tubes and hoses included in the delivery scope are attached to the rear of the AQUATOP TC.

Installation and Connection Instructions Heater-Side Connection Two different basic concepts exist: a) Direct connection, without buffer storage, comply with min. circulating water volume requirement The coil area of the service water storage must be adjusted to the heat pump capacity. b) Indirect connection, with buffer for hydraulic decoupling The coil area of the service water storage must be adjusted to the heat pump capacity.
Installation and Connection Instructions Condensate and Safety Line The condensate line and the safety line of the heating side must be installed freely visible and at an incline towards the building drainage system. L The safety line of the heat reclamation side (heat gain with brine) must be installed freely visible and at an incline, leading into a suitable collection container.
Electrical Connection General E Compliance with the corresponding SEV, EN, IEC, as well as the corresponding VDE standards is required for the electrical connection of the heat pump. The connection specifications of the local utility or electric company must be complied with as well. E The power supply to the equipment must be interrupted before each electrical connection or service or maintenance work. The upper cover on the equipment must be removed for the electrical connection.

Charging Geothermal Heating Systems Problems and Issues Incorrect Brine Concentration Flushing Problems Problems with charging a geothermal heating system (GHS) with antifreeze may occur occasionally and result in a reduced capacity of the system or even total system failure. Most problems are as follows: Dirt in the Circuit Drilling companies generally strive to fill only clean water into geothermal heating systems. However, dirt may reach the probe due to inattention.
Charging Geothermal Heating Systems Charging with Antifreeze Correctly Charging a Geothermal Heating System Circuit Charging with Antifreeze After flushing, the entire geothermal heating system circuit is to be filled with clean tap water. Follow the steps below to prepare the required concentration of antifreeze with a 100% concentrate. For example: The required antifreeze concentration is 25% (ideal range is 25-30%) with a 140-m Duplex® ø 32 mm BHE. (Content per meter = 4 pipes x 10 dm, length x 0.
Charging Geothermal Heating Systems Charging with Antifreeze Correctly Charging a Geothermal Heating System Circuit Heating and Brine Charging Valves L The brine circuit is to be charged with a charging pressure of 1 bar (diaphragm-type expansion vessel initial pressure) + 0.3 bar as brine header = total of 1.3 bar. L The temperature difference during this operation should not exceed 4 K between sole inlet and outlet. Flushing and charging (heating side).
