3.3.1 3.3.1 3.3.1 3.3.1 Proper intended useProper intended useProper intended useProper intended use Condensers of the GVH/GVV series are intended for installation in a refrigeration system and for outdoor installations. The condensers condense the refrigerant by giving off heat to the air that is moved by fans over the dry heat exchanger surface. The unit is delivered for operation with a specific operating point: • Condensation temperature • Refrigerant feed type • Airflow volume • Air inlet temperature • Relative air humidity.

The specified operating point is provided in the submittal offer documents.

3.3.2 Operation conditions3.3.2 Operation conditions3.3.2 Operation conditions3.3.2 Operation conditions The unit is a component of a refrigeration system including its refrigerant circuit. The purpose of these operating instructions, as part of the operating instructions manual (of which these operating instructions are a part), is to restrict the dangers to people and property and the environment from the unit and the refrigerant used in it to a minimum. These dangers are essentially connected with the physical and chemical properties of the refrigerant and with the pressures and temperatures that occur in the refrigerant-carrying components of the unit ((((see Residual hazards with see Residual hazards with see Residual hazards with see Residual hazards with CFC/HFCCFC/HFCCFC/HFCCFC/HFC refrigerantsrefrigerantsrefrigerantsrefrigerants, page , page , page , page 22221111))))....

5555. . . . SetSetSetSet----up and functionup and functionup and functionup and function The condenser consists of, • a heat exchanger arranged as consisting of pipe coils fitted with fins (copper tube, aluminum fin), headers and header’s outlets . • a self-supporting enclosure structure with side support and number of legs. The enclosure consists of galvanized sheet steel, painted. • and – depending on the version – with one or more low noise axial fans, with maintenance –free motors. The GVH/GVV condensers series are a refrigeration system component. The refrigeration system is a combination of refrigerant-carrying components and fittings connected with one another, which form a closed circuit, in which the refrigerant circulates. The refrigerant absorbs heat at low temperature and low pressure and evaporates (evaporator-side), and at higher temperature and higher pressure gives off the heat gain and condenses itself (condenser-side). The condenser condenses the refrigerant by giving off heat to the air that is moved by fans over the dry heat exchanger surface. The CFC/HFC refrigerants used (R134a, R404A, R407C, R507, R22, etc.) are group A1 refrigerants (see see see see Residual hazards with CFC/HFC refrigerantResidual hazards with CFC/HFC refrigerantResidual hazards with CFC/HFC refrigerantResidual hazards with CFC/HFC refrigerantssss, page 2, page 2, page 2, page 21111).

AC technologyAC technologyAC technologyAC technology The AC motors are protected against overheating by a thermo-contact. For motors with thermo-contact, the thermo-contact has to be wired in the switch cabinet in such a way that turning on the motor with triggered thermo-contact is not possible. A locking device is recommended for preventing reactivation. Motors with PTC resistors require an additional trigger device for the installed thermistors. Locking is recommended to prevent reactivation. Max. 2.5 V test voltage or current-limited meters may be used on thermistors. For motors with direct start and a connection value > 4.0 kW, a startup current limitation (soft start using thyristor) may be necessary. If frequency converters for speed control are used, the following has to be observed for external rotor motors: Between frequency converter and motor, an effective all-pole sine filter has to be installed (sinus-shaped output voltage, filter effective between phase against phase, phase against earth) Güntner frequency converters feature this function as standard. Güntner three-phase standard motors are suitable for direct operation on frequency converters. The three-phase fan motors can be operated by means of star-delta with two speeds and/or with speed control. The direction of rotation must be checked. If the direction is wrong, it can be changed by interchanging two phases. Electronic technologyElectronic technologyElectronic technologyElectronic technology

� Try to determine the size of the leak.

� Activate Emergency STOP switch. Valves, motors and other components are therefore switched off to prevent refrigerant from leaking.

� Close shut-off valves, especially to the liquid side, where possible in sections, so that the refrigerant

quantity in the leakage area is kept as low as possible. If possible evacuate/drain the systems section in question and move the refrigerant/ to other systems sections. Here too it must be ensured that no liquid refrigerant is locked in by shutting off system sections.

11.2 Inspection and maintenance plan11.2 Inspection and maintenance plan11.2 Inspection and maintenance plan11.2 Inspection and maintenance plan The regular safety – related checking of condensers in refrigeration system, is a prerequisite for meeting the local requirements and / or national requirements and these must be performed by a "qualified person". The operator must determine the test intervals for the complete system and the system components on the basis of a safety - related evaluation. Nevertheless, as with every technical installation, results, whereby it can generally be said the most frequent causes are not material errors, but operating errors, cannot be ruled out. The checks to be performed are listed in the following sections as time-scaled checklists.
