2General description
The industrial coolers of the KPC series are fully assembled, factory inspected and tested, and suitable for fully-
automated operation. The water or aqueous medium that undergoes cooling is constantly circulated by the
pumps. The temperature set 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 industrial coolers of the KPC series are fitted with pressure switches as protection against freezing and
excess temperature. With this, it is possible to set leaving water temperatures from +16°C to +25°C.
Antifrogen (ethylene glycol) must beadded atthe rate of 38vol.% and itdepends not on the ambient
temperature.
Changes in the settings should only bemade byqualified operatives.

2.1 Functional description
The cold water pump starts as soon as the master switch and the pump switch have been turned from 0 to 1.
The pump switch is 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 the case, the plant has either a leak or insufficient water. A flow switch acts to prevent
freezing of the evaporator if and when water volumes drop. The refrigerating machines switch on as soon as
the fail-safe 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 fine adjustment is performed by two hot gas by-pass valves.
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 timing relay provides overload protection to the compressor.
If the water temperature rise up to 30 °C (86 °F) the pump will stop after 30 min.
Please check the refrigerant circuit.
Restart is after reset of the button at the switch cabinet.
2.1.1 High-/Low- pressure control
The high-pressure (HP) control reacts to excess pressure of the magnitude of 19 bar
by shutting off the compressors.
Causes of this include
- failure of condenser fans,
- high outdoor temperatures,
- a dirty condenser.
The compressor can only be put back in operation when the reset switch is activated on the HP-pressure
control and the pressure has dropped.
An automatic start has not been provided for.
The low-pressure (LP) control also switches off the compressor when the pressure sinks to 1,0 bar. The switch
is by-passed during start-up for 90 s.
If after being at rest the pressure rises to 2,0 bar, the compressor will switch on again automatically.
2.1.2 Electronic controls
The control system consists of a 3-step controller. The reference value is set at the works at 18°C for the outlet
temperature. The sensor for the controller is installed on the outlet side.
Regulating refrigerating capacity
The exact regulation of the leaving temperature is achieved by means of 3-step controllers and hot gas by-pass
injectors with solenoid valves. The setting is based on approx. 50%, 75% of the machine’s refrigerating
capacity.
Condenser pressure regulation
the condenser-pressure is regulated with help of the Frequency Inverter.

3Brief 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.
3.2 Linking topower supply
The size of the connection cable had to be conform to the local regulations. For current values and power
input see “Switch gear” point 8.
The industrial coolers of the KPC 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 in the switch cabinet.
The cooling block is switched on via the master switch .
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.

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 Primus-Chiller KPC115-U/S stands near an Avanto-Chiller KCC215-L-U/S)
3.4 Filling the unit with water
Fill with clean water (drinking water quality) with Antifrogen (AFN)-additive.
Open front panel and fill to a pressure of min.1,5 bar via the feed cock.
After filling, check all connections for leakage.
3.5 Draining air from the unit
The KPC 115 includes a closed water system.
If air get out of the system the water pressure dropes down. If that happens you had to check the water
pressure and if its to low you had to refill the water circuit as shown in fig. 1.4
The procedure should be repeated until no more air is in the system
After all these steps, turn both switches to position "1". If all the prerequisites for operation have been met, the
chiller will start after 1 minute.
In case of malfunctions: search for faults, take note of Chapter 9, TROUBLE SHOOTING, in this manual.

The capacity of the lifting gear must be adequate to
lift the load in question.
Check the weight of the chiller units,
the capacity of the lifting gear and ropes
and the condition and suitability of the
aforementioned equipment.

6Installing the industrial cooler
The plant should be mounted in an upright position on a stable foundation.
(Weight with load: see technical specifications).
A distance should be kept free on all sides to allow sufficient access for operation and maintenance.
A space of 1,5 m must be left above the apparatus to ensure that air exhaust can leave freely.
Further details can be found in the following installation plans.

7Notes on the water connections
The water connections between industrial coolers of the KPC series and the water supply can be made of steel,
copper or plastic. The nominal widths of the piping for distances of up to approx. 45 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.
