Operating instructions

Hyfra-Industriekühlanlagen Industriepark 54 56593 Krunkel

Machine identification Type: LWK Important: These operating instructions have to be read carefully before putting the refrigerating plant into operation. The manufacturer can`t undertake any liability for damage or operating trouble resulting from the non-observance of these operating instructions. All rights for technical modification required for further development are reserved.

Proper use of the refrigerating plant The refrigerating plant is designed for the cooling of water. In case you intend to use other agents (e.g. deionised water) please contact the manufacturer. Limits indicated in the technical data must not be exceeded. Use of the plant to cool flammable or explosive substances is prohibited.

Please keep these operating instructions for further use!

5 STRUCTURE AND OPERATION 9

1 Safety / Prevention of accidents 1.1 General information

This manual contains basic information which has to be observed during initial start, operation and maintenance. Therefore these operating instructions are to be read by the installer or personnel in charge before putting the plant into operation. This manual must be available whereever the plant is operated.

Any general safety instructions mentioned in this chapter as well as those given in other sections of this manual have to be observed.

1.2 Qualification of personnel and training Operating, maintenance, inspection and installation personnel must be properly qualified for their work. Range of possibility, competence and supervision of the personnel must be determined by the operator.

1.3 Danger due to non-observance of safety instructions Non-observance of safety instructions may cause injuries, endanger the environment or damage the unit. Non-observance of safety instructions will result in the loss of right to claim for any damages.

1.4 Safe performance of work Any safety instructions given in this manual, including national regulations on accident prevention as well as any possible internal working, operating and safety instructions have to be observed.

1.5 Safety instructions for plant and operator

Protective guards that have been installed to prevent contact with moving parts may not be removed when the unit is being operated. Danger from electric energy must be excluded. (→ See VDE regulations of the local power supply companies for detailed information)

1.6 Safety instructions on maintenance, inspection and installation work Basically non of the cleaning or maintenance tasks may be performed until the unit has come to a complete stop. The shutdown procedure as described in this manual must be observed. As soon as this work has been carried out, all safety devices and protective equipment must be mounted or installed according to their proper function.

1.7 Arbitrary modification and production of spare parts The unit may be converted only if an agreement with the manufacturer has been reached. Original spare parts and accessories accepted by the manufacturer serve as safety devices. In case any other parts are used the liability for therefrom resulting trouble may be canceled.

1.8 Unacceptable operating methods The operational safety of the delivered unit is guaranteed only if the unit is properly used as intended. Limits indicated in the technical data must not be exceeded.

1.9 Safety symbols 1.9.1 Warning

!

This symbol is included next to all the safety instructions involving work that may result in serious injuries. Observe these instructions and act with extreme caution in such instances. Inform all other users as well. In addition to the instructions included in this manual the general safety and accident prevention regulations must also be taken into account.

1.9.2 Attention

This symbol is included next to the items in this manual that must be strictly observed to ensure proper application of the guidelines, regulations, instructions and procedure of tasks and that the machine or other parts are not damaged or destroyed.

1.9.3 Note

This refrigerating plant is designed according to state-of-the-art technology and is operationally reliable. Dangerous situations may, however, arise if the unit is used by personnel without proper training or if it is not used correctly according to its intended purpose. Accordingly, this may affect efficient operation of the unit.

2 Transport The refirgerating plant may only be transported in the original packaging to the site of initial operation. In case of damage supplier must be informed immediately. If the unit is moved to another location within a factory, all connections must be disconnected from the unit. Moving the unit to another location must be checked by an expert and repaired as required before it is put into operation again.

!

When transporting the unit, consider the weight indicated in the technical data. Use means of transportation with the corresponding minimum load capacity.

3 Installation and initial start

3.1 Set up

When setting up the refrigerating plant please observe strictly the following points:

• Assure that the required cooling air can be sucked in (see technical data). • The distance to buildings hindering the air inlet or outlet has to be at least 0,5 m. • The unit must not be set up next to a heater. • Due to intensive generation of heat, the unit must not be set up in the

immediate reach of a workplace. • The unit must be set up on level, solid surfaces only, so that stability is

ensured.

3.2 Electric supply

The refrigerating plants of series LWK are equipped with a mains plug. Mains voltage is 1/N/PE AC 50 Hz 230 V +6/-10 %.

3.3 Connection of the consumer

The unit to be cooled must be connected with the water-cooled air cooler by means of hose pipes. Out- Inlet are to be installed according to their marking. Before starting up the pump must be filled with the pumping medium and deaerated.

3.4 Refill of the store tank

A filler neck is provided at the casing box. 3.5 Putting the refrigerating plant into operation

After the tank has been filled with water the unit can be put into operation by means of the plug.

The water-cooled air cooler must be switched on before the unit to be cooled. In this manner any non-permissible rise in temperature of the medium is avoided.

Switching on the pump for the first time makes water level in tank sink. Any loss in water must be refilled.

The operator has to ensure that only authorized personnel works at the refrigerating plant.

3.6 Non permissible operating states and working methods

Since the pump of series LWK is not protected by a bypass valve, the flowing-through on the consumer’s side must not be throttled on zero. The water level of the tank can be lowered after some time according to possible leaks. Dry-running of the pump can damage the pump. Therefore the water level of the tank has to be checked everyday and water refilled if necessary.

Non-observance of these instructions may lead to premature defect of the pump.

4 Maintenance

4.1 Inspection 4.1.1 General information

In case of irregularities during operation of mechanically-working aggregates or extraneous noise the refrigerating plant must be switched off.

4.1.2 Medium to be cooled • Cleanness control of the medium to be cooled must be checked everyday. In

case of need let off the medium, rinse and refill the cooling circuit. The pump has to be cleaned in this case.

• Check water level of the tank daily and refill water if necessary.

4.2 Cleaning of condenser

• Make sure that lamellas of the condenser remain clean in order to guarantee required heat exchange. As demanded by ambience conditions lamellas of condenser should be cleaned in determined time intervals. Dust and fluffing e.g. may be removed by means of compressed air.

4.3 Standstill for prolonged period

In case of longer standstill of the refrigerating plant, it is advisable to empty water circuit completely. For renewed start-up of refrigerating plant make the same controls as for the initial start-up.

The cooling water is sucked out of the tank (4) by means of the pump (1) and transported to the consumers. Warm water flowing back from the consumers is cooled in the heat exchanger (3). The plants of series LWK are air-cooled water coolers which means that the temperature of water flowing back into the tank is about 10 °C above ambient temperature. Pump (6) and paddle (7) are run by the same engine.
