2 General description
The chiller KSC215-L-U/S are fully assembled, factory inspected and tested, and suitable for fully-automated operation. The water ethylene glycol mixture that undergoes cooling is constantly circulated by the pump in a closed system which is monitored by an flow switch and an expansion tank. The temperature is controlled by an Siemens SPS. The settings on the governor is kept automatically within the limits that are possible for the given degree of temperature exactitude.
The process heat is transmitted from the water in the in-built heat exchanger (evaporator) to the refrigerant circuit (R 134a). The compressor raises the refrigerant to a higher temperature and pressure so that the warmth can be released via the condenser to the surrounding air. Consequently good air supply and escape are vital for the proper running of the plant. The condenser-pressure is controlled by a Frequency inverter for the condenser fan speed.
The chiller KSC215-L-U/S are fitted with low-pressure sensor as protection against freezing and excess temperature. With this, it is possible to set leaving water temperatures from +19°C to +22°C.
Ethylene glycol must be added at the rate of min. 35vol.% to max. 38vol.% and it depends not on the
ambient temperature!
Do not use automotive ethylene glycol!!!
Changes in the settings should only be made by qualified operatives

2.1 Functional description
The cold water pump starts as soon as the master switch 5Q1 have been turned from “OFF” to “ON”.
The pump main switch should only to be turned to “On” when the aqueous medium circuit has been completely filled and all air has been removed.
The flow switch protecting of the refrigerating compressors is cut off during start-up.
The pressure on the delivery side of the pump rises directly with the system pressure.
Should this fail to be in case the plant has either a leak or insufficient water. A flow switch acts to prevent freezing of the evaporator when water volumes drop. The refrigerating machines switch on as soon as the safety sequence, flow switch and control motor-protection pump is in order.

A lag in connection time has been allowed for in the refrigeration compressors to avoid surges in the current. The refrigeration compressors keep running as long as cold is required and the reference value for the water temperature has not been reached.
The water pump remains in constant operation.
Apart from which, the refrigerating machines are only ever switched off during circulation in cases of low or high pressure in the refrigeration cycle.
When switched off in the normal way, a restart delay provides overload protection to the compressor.
The refrigerant circuits which starts first is changed after 24hours when the difference between the water return and supply is smaller than 0,7K for a dedicated time .

3 Brief operating instructions
See also chapter 5 – 10 in this operating instruction
3.1 Installing, maintenance and repair
Only qualified operatives with the requisite knowledge, equipment and facilities should maintenance and repair the KKT chiller.
If its necessary to change the filling weight of the refrigerant circuit, please note:
Fill only with the refrigerants listed on the manufacturer name plate, and only up to the indicated filling weight. See also the enclosed Installing instruction
page 11von138
3.2 Linking to power supply
The size of the connection cable had to be conform to the local regulations. For current values and power input see wiring diagram page 2.
The industrial coolers of the KSC series are generally designed for a main supply of 480V 3Ph 60 Hz.
The connection L1, L2, L3, PE is performed via the terminal block X1 (power supply) in the switch cabinet.
The cooling block is switched on via the main switch 5Q1.
3.3 EMC Compatibility and Grounding
This comments are compiled to help the field electrician to install the grounding of the power supply and to get a EMC Compatibility. All electrical equipment produces radio and line-borne interference at various frequencies. The cables pass this on to the environment like an aerial. The basic countermeasures are isolation of the wiring of control and power components, proper grounding and shielding of cables.
A large contact area is necessary for low-impedance grounding of HF interference. The use of grounding straps instead of cables is therefore definitely advisable.
Moreover, cable shields must be connected with purpose-made ground clips.
The grounding surface must be highly conductive bare metal. Remove any coats of varnish and paint.
Operating Instruction
Healthcare chiller of the KSC Series
Version „Revision 09“
The width of the grounding wire must be min. 16mm² (AWG 6) or of the same width of the power supply. The grounding must be an isolated ground and must connected on the ground terminal (X1) in the switch cabinet. The ground resistance must be less than 10 Ohm.
Metal cable conduits are not allowed for grounding.
The piping of the chiller (supply and return) have to be grounded too.
Do not share the ground wire with other devices. Always use a ground wire that complies with technical standards on electrical equipment and minimize the length of the ground wire.
When using more than one Inverter, be careful not to loop the ground wire. (e.g. a CT-Chiller KPC108-L-U/S stands near an Avanto-Chiller KSC215-L-U/S)

3.3 Filling the unit with water-ethylene glycol-mixture
Water to be used (de-ionized water / destilled water / VE water / bartly de-ionized water) This type of water has to be purchased and provided locally Mix it with Ethylene-glycol at the rate of min. 35% to max. 38%. Use ethylene-glycol of only one manufacturer. (e.g.: DOWTHERM SR1-Dow Chemical, Safeflow EG-Clariant) Do not mix two ore more different manufacturer for one water-ethylene-glycol circuit. Open front panel and fill to a pressure of min.1,5 bar via the feed cock when the pump is off. After filling, check all connections for leakage. Don’t use propylene-glycol or automotive antifreeze

3.4 Draining air from the unit
The KSC 215 includes a closed water system.
If air get out of the system the water pressure drops down. If that happens you had to check the water pressure and if its to low you have to refill the water circuit.
The procedure should be repeated until no more air is in the system
After all these steps, turn the main switch in position "1". If all the prerequisites for operation have been met, the chiller will start at the latest 1 minute. In case of malfunctions: search for faults, take note of Chapter 9, TROUBLE SHOOTING, in this manual.

7 Notes on the water connections
The water connections between industrial coolers of the KSC series and the IFP of Siemens can be made of stainless steel, copper or plastic. The nominal widths of the piping for distances of up to approx. 25 m should match at least the dimensions of the fittings on the appliance. (see technical specifications)
Reductions in diameter should be avoided. In case of longer pipelines, the pump pressure should be tested. When choosing the pipe materials, ensure that no electrochemical series are created.
The proper way to seal the European fittings can be done with any of following steps.
1. Pipe sealing cord. There are a number of brands available, however we use Loctite 55
2. Teflon Tape and a Anaerobic sealant.
3. Teflon Tape an Nylog sealant.
As with any sealant, the application instruction must be followed for proper use.

9.2 Explanations about the automatic restart of the Chiller KSC215-L-…
The following power failure situations are considered:
1. Main switch: On => Off => On
2. Mains supply: ok => power failure => power returns
9.2.1 Main switch: On => Off => On
When switching the main switch off and on again, the operator’s display shows the a failure message called „phase sequence“ (blinking) and at the electrical cabinet the green and the red indicator lamps are blinking to indicate this failure. After a start-up time of around 20 sec., the chiller will restart automatically and the life bit is on again. The red indicator lamp blinking goes off again and the green lamp continues blinking to indicate that
in the past in this situation a power failure / interruption occurred.
The chiller restarts automatically!!!!
In case the chiller does not restart automatically, the failure is still pending!
9.2.2 Mains supply: ok => power failure => power returns
Once power returns after a failure (phase sequence or phase failure), the screen also displays the error message „phase sequence“ and the green indicator lamp at the electrical cabinet blinks to indicate that a failure
had occurred
The chiller restarts automatically!!!!
Once the power supply has stabilized again, the 20 secs, the red indicator lamp goes off, the life bit is on again, the green indicator lamp saying that a failure was pending
In case the chiller does not restart automatically, the failure is still pending or another failure exists!
To set off the failure message at the operator’s display, press the „ACK-button“ at the display unit.
The blinking green or red indicator lamp at the electrical cabinet becomes permanent (green lamp) or goes off (red lamp), if the „black RESET-button“ at the electrical cabinet is actuated.
is still blinking and at the display the failure message „phase sequence“ remains visible.

10 Preventive Maintenance: Weekly Check, Two times a year Check
Service and maintenance should always be carried out by skilled technician and, where possible, under a maintenance contract. Nevertheless, certain routine work can be effectively carried out by non-specialists and may become important factor in preventing future damage to the plant.
Weekly Check
1. Check the working of the compressor:
Look out for too high head temperatures or suspicious noises.
2. Check the refrigerant charge through the sight-glass
3. Check that fans are rotating normally and not making unusual noises
4. Check that the temperatures is within the accepted limit.
If it is not, check that all the separate elements of the unit are working, by switching them on individually.
If they are not, see the fault finding guide (9 TROUBLE SHOOTING).
Two times a year Check

Operation Plate Heat Exchanger (PHE)
Before each operation make sure that the plate pack is clamped to the correct compression dimension "a" and that the plate heat exchanger is anchored to the ground.
Additionally make sure that all connection pipes are screwed tight and that the permitted values for pressure and temperature given on the fabrication label are not exceeded.
The correct compression dimension can be found on the supplied dimension sheet or fabrication label. Prevent pressure surges when starting up the PHE or after brief stoppages.
If an operating PHE is shut down, it should be cooled down and cleaned afterwards. The plate pack should be loosened to "a" + 10%, starting from the current "a" dimension. This action reduces the pressure on the gaskets
