1. GENERAL USER AND MAINTENANCE MANUAL

1.1 HOW TO USE THIS MANUAL

This operating and maintenance manual is intended for specialist personnel who are responsible for the

installation, commissioning and operation of cooling water recirculating chillers of the type CHW, oil recir-

culating chillers of the type CHO and glycol recirculating chillers of the type CHG. The term “chiller” is

used as a general name for these appliances.

This operating and maintenance manual is an essential constituent of the chiller. Every user, operator

and service technician is required to carefully read the information and instructions contained in this op-

erating and maintenance manual – particularly those that affect safety – before transporting, installing,

using, performing any maintenance on or disposing of the chiller.

The owners and operators of the chiller shall ensure that all work to be carried out on the chiller is only

undertaken by personnel with suitable specialist qualifications.

The operating and maintenance manual is divided into two sections that contain a detailed description of

the three type series CHW, CHO and CHG, with their respective standards and with additional information

on the customer-specific design and the respective model of your chiller, wherever this differs from the

standard model. Here you will find information such as the circuit diagram for the chiller you have cho-

sen.

1.2 GENERAL DESCRIPTIONS/INTENDED USE

The CHW, CHO and CHG chillers have been designed for the purpose of keeping a certain quantity of

cooling medium, e.g. water, water-glycol moisture or oil constantly within certain temperature limits (op-

erating range), with the aid of a technical cooling process. The most commonly used cooling medium,

also called the “consumer refrigerant” is mains water. This operating manual uses the general term cool-

ing medium. However, the cooling medium and the materials used in the circuit must be compatible with

one another. It is therefore necessary to check and ensure before commissioning that the cooling me-

dium is suitable for the intended purpose.

These chillers are recommended for use in the recirculated chilling of liquids (cooling media) in industrial

and commercial applications, particularly in cases where specific and constant temperatures are required,

such as in mechanical engineering, in the plastics industry, in surface technology and in the laser indus-

try.

Explanation of the product designations CHW, CHO and CHG:

CHW recirculating water chiller

CHO recirculating oil chiller

CHG recirculating glycol chiller

All work connected with the installation, operation and maintenance of the chiller must be performed in

accordance with the instructions contained in the operating and maintenance manual and in compliance

with the legal provisions that apply in the country where the device is installed. All cleaning/maintenance

work that requires access to the chiller has to be performed by qualified specialist personnel who have

been informed of the necessary precautions to be taken. Read the operating and maintenance manual

carefully before performing any work on the device. The chiller has been designed and manufactured in

such as way as to comply with the standards that apply in the respective country. Should the chiller be

used for the incorrect purpose or not in accordance with the operating and maintenance manual, the

manufacturer cannot be held responsible.

THE FOLLOWING POINTS MUST BE OBSERVED BEFORE COMMISSIONING AND WHILE OPERATING THE

CHILLER:

Familiarize yourself with all the operating controls.

The chiller may be used solely for the intended purpose.

Make sure that all the working limits indicated in the operating and maintenance manual are

observed.



Use protective devices to check electrical insulation. Do not carry out any work on any parts

of the equipment that might be live with wet clothing, hands or feet.



Check at regular intervals whether the safety and control devices of the chiller are functioning

properly.

Never hit the pipes located on the inside of the chiller with objects of any kind.

Any maintenance operations not mentioned in the operating and maintenance manual must

not be carried out by personnel without the manufacturer’s prior written authorization if any

equipment components are under pressure.



Never spill or pour any cooling medium into the environment as this may cause damage to

health. Before the chiller is resold, the cooling medium must be drained from the chiller using

suitable equipment. Please contact customer service of the nearest dealer in this connection.



The side panels of the chiller must not be removed unless this is absolutely necessary. Even if

the side panels are only partially removed, isolate the chiller from the electricity supply and

affix a sign to the control panel bearing the warning “Maintenance work on chiller in pro-

gress”. Replace the side panels as quickly as possible.

The components of the chiller must not be modified in any way.



Bypassing the electrical protective devices may result in overloading of the chiller.

The chillers are exclusively designed for cooling the types of cooling medium listed in the following table.

CHW series: Water with ethylene glycol added as anti-freeze, where necessary. If glycol is used,

the minimum limit of 20% and maximum limit of 25% should be observed.

CHO series: Lubricating or hydraulic oil with a viscosity of 10 cST or higher with a temperature

limit varying according to the oil type.

CHG series: Water with ethylene glycol added as anti-freeze with a minimum of 20% and a maxi-

mum of 25% applying to chillers with a standard configuration.

The maximum operating conditions (temperature of the cooling medium and room temperature) and the

permissible features for the cooling medium are contained in Section 5 of this manual.

When handling liquids intended for a special purpose, e.g. health or food applications, please

check the contractually defined technical specifications. Cooling medium with a high content of

solid matter may not be used with these chillers.

Possible risks:

CAUTION: The chiller is equipped with a main switch.

The authorized installation technician must ensure that the chiller has been connected to the

electricity mains in accordance with the standard EN 60204 and must ensure compliance with all

other applicable national standards.

Fire:

According to European Standard EN 378-2, these chillers may be equipped with a safety valve for drain-

ing cooling medium.

710.1760.00.04-03A 28/11/2012

The electricity supply must be disconnected in the event of fire. Fire extinguishers or fire extinguishing

systems filled with powder, foam or carbon dioxide should be used by preference. The chiller may also be

cooled with nebulized water. The use of water in large quantities must be avoided because if there is

leakage of refrigerant, the resulting chemical reaction – no matter how slight – may have a corrosive ef-

fect.

In any case, it is necessary to reduce the ambient temperature and/or that of the chiller and wait for the

temperature to fall before carrying out any work on the unit.

You are advised to include this device in your Fire Prevention Plan and Factory Safety Plan.

Make sure that suitable precautions have been implemented to avoid and combat any possible risks.

In the event of refrigerant leakage:

The refrigerant may lead to asphyxiation if it is inhaled in high concentrations. It is necessary to ensure

adequate ventilation for the room in which the chiller is installed.

Be sure to the read the safety data sheet with the relevant values and warnings.

Excessive pressure on the cooling medium side:

The chiller is equipped with safety devices on the cooling medium side.

These have to be mounted by the installation technician. The installation of any such devices must com-

ply with the applicable national standards and be carried out in accordance with the limits given in this

manual.

Depletion of the ozone layer:

The use of HFC refrigerants, in compliance with Regulation CE/842/2006, reduces damage to the ozone

layer and minimizes the greenhouse effect.

. DESCRIPTION OF THE CHILLER, COMPONENTS AND OPTIONS

.1 DESCRIPTION

The chiller is supplied ready for connection. It consists of a housing, a fully hermetically sealed cooling

medium circuit, the refrigerant circuit, the cooling medium circuit and the electrical circuit, including all

control and monitoring devices which are required for fully automatic operation. The selected and used

cooling medium must comply with environmental standards and the legal provisions.

.2 REFRIGERANT CIRCUIT

STANDARD COMPONENTS USED IN THE CHILLER

The preceding abbreviations indicate the position in the drawings.

Not all components are contained in all models.

C– Compressor

Scroll-type compressor of fully hermetic design with integrated bimetal switch and oil sight glass.

Semi-hermetic compressor:

Semi-hermetic compressor with integrated bimetal switch and oil sight glass.

Reciprocating piston compressor:

Reciprocating piston compressor, fully hermetic with integrated bimetal switch and, in most models, an

oil sight glass.

CND – Condenser / Condenser safety grating

Condenser as fin-type heat exchanger consisting of copper pipes with aluminium fins. The safety grating

for the housing protects the condenser on the inside against mechanical damage. The positioning of the

condenser avoids any additional heat load on the components located inside the housing.

EVA – Evaporator

Insulated shell tube heat exchanger or stainless steel plate heat exchanger.

HP – High-pressure pressostat

The high-pressure pressostat protects the refrigeration circuit of the chiller against excessively high oper-

ating pressure (high-pressure fault).

In this kind of fault, the high-pressure pressostat switches the compressor off when the preset limit is ex-

ceeded. The compressor cannot be started up again until the preset differential pressure has been

reached and the Reset button located inside the chiller has been pressed. The fault is displayed on the

control unit.

LP – Low-pressure pressostat

The low-pressure pressostat protects the refrigeration circuit of the chiller against excessively low operat-

ing pressure (low-pressure fault).

710.1760.00.04-03A 28/11/2012

When this kind of fault occurs, the low-pressure pressostat switches the compressor off when the preset

limit is undershot. The compressor starts up automatically if when the permitted pressure ratios have

been re-established between the high and low pressure sides via the internal pressure compensation sys-

tem. The fault is displayed on the control unit while it persists.

Manometer in the refrigeration circuit

MHP – High-pressure manometer:

The manometer shows the pressure on the high-pressure side within the refrigeration circuit. The dis-

play is located on the connection side, above the cooling medium connections.

MLP – Low-pressure manometer

The manometer shows the pressure on the low-pressure side within the refrigeration circuit. The display

is located on the connection side, above the cooling medium connections.

PV – Pressostatic fan control

The condensation pressure is controlled by pressostatic activation and deactivation of the fans. This type

of control allows adaptation to different operating conditions at constant condensation temperatures.

R – Crank case heating

The electrical crank case heating is activated after the main switch has been turned on. It protects

against a refrigerant accumulating in the compressor. This avoids faults during the compressor start-up

phase at low ambient temperatures.

V – Ventilator (fan)

Axial: Low-noise axial ventilator (maintenance-free).

Radial: Low-maintenance radial ventilator for connection to an air duct on the customer’s premises.

Injection process

a. Capillary injection (up to cooling capacities of approx. 2.5 kW).

The refrigerant is injected via a defined capillary.

VE – Expansion valve (from cooling capacities of approx. 2.5 kW)

Thermostatic valve that limits the evaporation pressure to a maximum.

(MOP; maximum operating pressure).

Piping (cooling system)

Closed pipe system made of copper tubing, including fittings. Supplied as required with additional fittings

such as non-return valves, filter drier, sight glass and service connections.

OPTIONS – REFRIGERATION CIRCUIT

Condenser air filter, aluminium (reusable)

The condenser air filter protects the condenser against dirt. It is easy to clean and can be reused over a

long period of time.

IAF – Air filter monitoring

Heavy contamination of the air filter is indicated by an acoustic warning signal visible on the controller,

which is triggered by the pressostat.

Variable fan speed control

The condensation pressure is kept at a constant level by fans with a speed control and is particularly

suitable for use at extremely low ambient temperatures.

Hot gas bypass regulating device

The bypass pipe with solenoid valve and throttle device is used when there are exact requirements on the

constancy of the cooling medium outlet temperature or when there are high load fluctuations.

Water-cooled condenser (instead of air-cooled condenser)

This consists of a plate heat exchanger or a shell tube heat exchanger that uses existing cooling water to

condense the refrigerant. It replaces the finned pack heat condenser and the fan.

This cools and recondenses the refrigerant. The cooling water requirement can be adjusted according to

the condensation pressure with a pressostatic control valve.

. COOLING MEDIUM CIRCUIT (CONSUMER CIRCUIT)

STANDARD COMPONENTS USED IN THE CHILLER

MF –Manometer for the cooling medium

In chillers with an integrated pump, the manometer indicates the pressure at the cooling medium outlet.

In chillers with no integrated pump, the manometer indicates the pressure at the cooling medium inlet.

P – Pump

A single-stage or multi-stage centrifugal pump of horizontal or vertical design is used according to the

type of model.

710.1760.00.04-03A 28/11/2012

Differential pressure monitor

The differential pressure monitor protects the plate heat exchange of the chiller against excessively low

flow rates and hence against damage caused by ice formation.

OPTIONS – HYDRAULIC CIRCUIT

BP – Automatic bypass / Overflow valve

The overflow valve is intended to guarantee a minimum throughput in the cooling medium circuit. This

protects the evaporator and the pump.

BPM – Manual bypass

This type of bypass can be used to manually adjust the minimum throughput in the cooling medium cir-

cuit.

CAA – Automatic cooling medium feed via a float valve

The cooling medium is filled up automatically by the float valve if the level in the tank falls below a mini-

mum.

EV 1 – Solenoid valve 1 (connect without current) in return circuit

These valves should be used in open systems when the consumers are installed on a higher level. This is

generally used as a valve combination with VNR (see below).

FL – Flow controller

The flow controller located in the cooling medium inlet monitors the flow in the cooling medium and con-

sumer circuit. It switches the cooling system off if the throughout falls below a minimum.

LVE – Flow switch (systems open to the atmosphere with tank)

The flow switch is located in the tank and monitors the cooling medium level.

If the water level falls and reaches the minimum value, the cooling system and the pump(s) are switched

off. The chiller cannot be switched on again until the cooling medium has been filled up to the MAX mark

on the level display.

RA – Tank heating

The tank heating warms the cooling medium in the tank. It is used to achieve the optimum operating

temperature within a short time if there is a low ambient temperature and no process heat is being

added.

TD – Digital thermometer in return circuit (systems with single and dual circuit)

The digital thermometer shows the inlet temperature of the cooling medium.

VNR – Non-return valve in the supply line

These valves are used in open systems when the consumers are positioned at a higher level and prevent

uncontrolled flow of the cooling medium back into the tank when the pump is stationary. They are gener-

ally used in combination with a solenoid valve (EV, see above).

Dirt trap

If there is a risk of the cooling medium becoming contaminated by solids with a diameter > 1 mm during

operation, a dirt trap with an appropriate mesh width has to be used. This should preferably be fitted

outside of the chiller so that it can be cleaned easily. It is important to note the flow direction. The dirt

trap must be cleaned at regular intervals after commissioning the chiller, or as required.

Pump alternatives

A pump is provided as standard and supplies a pressure of 2 to 3 bar at the defined nominal flow rate.

Other pumps can of course be selected according to the project. Depending on the pressure and volume

it may be necessary to carry out adjustments to the system characteristics with the aid of control valves.

SINGLE-CIRCUIT SYSTEM WITH TANK (STANDARD)

The cooling medium circuit has been designed as system open to the atmosphere. The circuit consists of

the following components:

pump of horizontal or vertical design,

tank, open to the atmosphere, thermally insulated with draining facility, optical filling level indica-

tor and cover to prevent contamination of the cooling medium.

piping system consisting of copper or plastic pipes with manometer and probe connection for the

operating thermostats.

The volume of cooling medium in the tanks is a contributory factor to maintaining the constancy of the

cooling medium outlet temperature. The pump conveys the cooling medium within the circuit out of the

tank to the consumer and then back into the tank via the evaporator.

SINGLE-CIRCUIT SYSTEM WITHOUT TANK

The cooling medium circuit is designed as a single-circuit system without tank. The pump conveys the

cooling medium inside the circuit through the evaporator and through the consumer.

The cooling medium in cooled inside the evaporator. The circuit consists of the following components:

pump of horizontal or vertical design,

piping system consisting of copper or plastic pipes with manometer and probe connection for the

operating thermostats and the digital temperature display.

If designed as a system closed to the atmosphere, the external circuit must be provided with

venting connections and with pressure compensation tank if required!

.4 ELECTRIC CIRCUIT

STANDARD COMPONENTS USED IN THE CHILLER

ALR – Composite Failure Report

The composite failure report summarizes all fault messages from the compressor, the pump(s), fan(s) of

the high-pressure and low-pressure pressostats, the flow monitor as well as the breakage of probes.

Voltage-free series connection of this composite report takes place at the terminals in the switch cabinet

(see circuit diagram in the Annex).

710.1760.00.04-03A 28/11/2012

IG – Main switch

The chiller carries no current after it has been turned off with the main switch. The switch is located on

the door of the switch cabinet.

MTC – Motor protection switch for compressor

If the motor current increases beyond the set value or if there is a short circuit, the motor protection

switch turns off and interrupts the current supply. The motor protection switch has to be turned on

manually after the cause of the malfunction has been eliminated. The motor protection switch is located

in the switch cabinet.

MTP – Motor protection switch for pump

If the motor current increases beyond the set value or if there is a short circuit, the motor protection

switch turns off and interrupts the current supply. The motor protection switch has to be turned on

manually after the cause of the malfunction has been eliminated.

The motor protection switch is located in the switch cabinet.

ROO – Remote control

The chiller can be switched off by the consumer or from a control room with the aid of an external con-

tact. When this occurs, the main switch remains permanently switched on.

QE – Switch cabinet

The switch cabinet contains all the electrical components and safety devices.

TLT – Temperature controller

Temperature control and regulation is carried out by the temperature controller of the chiller in accor-

dance with the preset value.

The temperature controller with digital display is integrated in the door of the switch cabinet. Fault mes-

sages are displayed on the temperature controller by means of codes.

OPTIONS – ELECTRIC CIRCUIT

Connecting cable with CEE plug

A ready-to-use mains cable is supplied with 6m oilflex cable and CEE plug 4-pole (3P+PEN) or 5-pole

(3P+N+PE).

Compressor winding protection

Depending on the compressor type, the protection is provided either by Klixon (bimetal strip) or by a

temperature probe. If the maximum permissible winding temperature is attained, the motor protection

switch turns off the compressor.
