The unit must be firmly secured to the soil.

It is essential to observe the following instructions:

• The unit can only be lifted using the lifting points marked in yellow fixed to its base.
• It is forbidden to access the electrical components without having opened the unit main switch and switched off the power supply.
• It is forbidden to access the electrical components without using an insulating platform. Do not access the electrical components if water and/or moisture are present.
• Sharp edges and the surface of the condenser section could cause injury. Avoid direct contact and use adequate protection device
• Switch off power supply, by opening the main switch, before servicing the cooling fans and/or compressors. Failure to observe this rule could result in serious personal injury.
• Do not introduce solid objects into the water pipes while the unit is connected to the system.
• A mechanical filter must be installed on the water pipe connected to the heat exchanger inlet.
• The unit is supplied with safety valves, that are installed both on the high-pressure and on the low-pressure sides of the refrigerant circuit.

It is absolutely forbidden to remove all protections of moving parts.

In case of sudden stop of the unit, follow the instructions on the Control Panel Operating Manual which is part of the onboard documentation delivered to the end user.

It is strongly recommended to perform installation and maintenance with other people. In case of accidental injury or unease, it is necessary to:

- keep calm

• press the alarm button if present in the installation site or open main switch.
• move the injured person in a warm place far from the unit and in rest position
• contact immediately emergency rescue personnel of the building or the Health Emergency Service
• wait without leaving the injured person alone until the rescue operators come
• give all necessary information to the rescue operators

Avoid installing the chiller in areas that could be dangerous during maintenance operations, such as platforms without parapets or railings or areas not complying with the clearance requirements around the chiller.

Noise

The unit is a source of noise mainly due to rotation of compressors and fans.

The noise level for each model size is listed in sales documentation.

If the unit is correctly installed, operated and manteined the noise emission level do not require any special protection device to operate continuously close to the unit without any risk. In case of installation with special noise requirements it could be necessary to install additional sound attenuation devices.

Moving and lifting

Avoid bumping and/or jolting during loading/unloading unit from the truck and moving it. Do not push or pull the unit from any part other than the base frame. Secure the unit inside the truck to prevent it from moving and causing damages. Do not allow any part of the unit to fall during transportation or loading/unloading.

All units are supplied with the lifting points marked in yellow. Only these points may be used for lifting the unit, as shown in the following figure.

Both the lifting ropes and the spacing bars must be strong enough to support the unit safely. Please check the unit's weight on the unit nameplate.

The unit must be lifted with the utmost attention and care following lifting label instructions; lift unit very slowly, keeping it perfectly level. Follow the rigging instruction described en the label attached on the electrical panel of the unit.

Rigging instruction

• The lifting equipment, ropes/chains, accessories and the rigging procedure must be in conformity with local regulations and current rules.
• Only the lifting points, present in the base frame, must be used to lift the unit. Lifting point are identified by yellow colour. The number of fans can very from this diagram depending on the size of the unit.
• All lifting points must be used during rigging procedure.
• Only closable hooks must be used during rigging procedure.
• Ropes/chains and hooks must be adequate for load. See specific lifting weight of the unit on the identification label.
• Crosswise spreader bars 1400 mm (EWAQ210GZ) and 2300 mm (EWAQ270GZ\~EWAQ400GZ) long must be used to avoid damage to the unit.
• Lifting ropes/chain must have a minimum length as it is specified in the drawing.
• The installer has the responsibility for proper sizing of rigging
• Equipment and its proper use. It's recommended to use ropes/chains each with minimum vertical load capacity equal or larger than unit weight.
• The unit must be slowly lifted and properly leveled. Adjust the rigging equipment, to guarantee the leveling.

Positioning and assembly

All units are designed for installation outdoors, either on balconies or on the ground, provided that the installation area is free of obstacles that could reduce air flow to the condensers coil.

The unit must be installed on a robust and perfectly level foundation; should the unit be installed on balconies or roofs, it might be necessary to use weight distribution beams. For installation on the ground, a strong concrete base, at least 250 mm thickness and wider than the unit must be provided. This base must be able to support the weight of the unit. If the unit is installed in places that are easily accessible to people and animals, it is advisable to install protection grids for the condenser and compressor sections.

To ensure best performance on the installation site, the following precautions and instructions must be followed:

• Avoid air flow recirculation.
• Make sure that there are no obstacles to hamper air flow.
• Make sure to provide a strong and solid foundation to reduce noise and vibrations.
• Avoid installation in particularly dusty environments, in order to reduce soiling of condensers coils.
• The water in the system must be particularly clean and all traces of oil and rust must be removed. A mechanical water filter must be installed on the unit's inlet piping.

Minimum space requirements

It is fundamental to respect minimum distances on all units in order to ensure optimum ventilation to the condenser coils.

When deciding where to position the unit and to ensure a proper air flow, the following factors must be taken into consideration:

- avoid any warm air recirculation

- avoid insufficient air supply to the air-cooled condenser.

Both these conditions can cause an increase of condensing pressure, which leads to a reduction in energy efficiency and refrigerating capacity.

Any side of the unit must be accessible for post-installation maintenance operations. Figure 4 shows the minimum space required.

Vertical air discharge must not be obstructed.

If the unit is surrounded by walls or obstacles of the same height as the unit, this must be installed at a distance no lower than (see Figure 4C or 4D). If these obstacles are higher, the unit must be installed at a distance no lower (see Figure 4E or 4F).

Should the unit be installed without observing the recommended minimum distances from walls and/or vertical obstacles, there could be a combination of warm air recirculation and/or insufficient supply to the air-cooled condenser which could cause a reduction of capacity and efficiency.

In any case, the microprocessor will allow the unit to adapt itself to new operating conditions and deliver the maximum available capacity under any given circumstances, even if the lateral distance is lower than recommended, unless the operating conditions should affect personnel safety or unit reliability.

When two or more units are positioned side by side, a distance of at least (see Figure 4G or 4H) between condenser banks is recommended.

For further solutions, please consult manufacturer representative.

Sound protection

When sound levels require special control, great care must be exercised to isolate the unit from its base by appropriately applying anti-vibration elements (supplied as an option). Flexible joints must be installed on the water connections, as well.

Water piping

Piping must be designed with the lowest number of elbows and the lowest number of vertical changes of direction. In this way, installation costs are reduced considerably and system performance is improved.

The water system must have:

1 Anti-vibrationmountingsinordertoreduce transmission of vibrations to the struc
2. Isolating valves to isolate the unit from the water system during service.
3. Manual or automatic air venting device at the system's highest point.; drain device at the system's lowest point.
4. Neither the evaporator nor the heat recovery device must be positioned at the system's highest point.
5. A suitable device that can maintain the water system under pressure (expansion tank, etc.).
6. Water temperature and pressure indicators to assist the operator during service and maintenance.

1. A filter or device that can remove particles from the fluid. The use of a filter extends the life of the evaporator and pump and helps to keep the water system in a better condition.
2. Evaporator has an electrical resistance with a thermostat that ensures protection against water freezing at ambient temperatures as low as -25^ .

All the other water piping/devices outside the unit must therefore be protected against freezing.

1. The heat recovery device must be emptied of water during the winter season, unless an ethylene glycol mixture in appropriate percentage is added to the water circuit.

2. If case of unit substitution, the entire water system must be emptied and cleaned before the new unit is installed. Regular tests and proper chemical treatment of water are recommended before starting up the new unit.

3. In the event that glycol is added to the water system as anti-freeze protection, pay attention to the fact that suction pressure will be lower, the unit's

performance will be lower and water pressure drops will be greater. All unit-protection systems, such as anti-freeze, and low-pressure protection will need to be readjusted.

1. Before insulating water piping, check that there are no leaks.

Water treatment

Before putting the unit into operation, clean the water circuit. Dirt, scales, corrosion debris and other material can accumulate inside the heat exchanger and reduce its heat exchanging capacity. Pressure drop can increase as well, thus reducing water flow. Proper water treatment therefore reduces

the risk of corrosion, erosion, scaling, etc. The most appropriate water treatment must be determined locally, according to the type of system and water characteristics. The manufacturer is not responsible for damage to or malfunctioning of equipment caused by failure to treat water or by improperly treated water.

Evaporator and recovery exchangers anti-freeze protection

All evaporators are supplied with a thermostatically controlled anti-freeze electrical resistance, which provides adequate anti-freeze protection at temperatures as low as -25^ . However, unless the heat exchangers are completely empty and cleaned with anti-freeze solution, additional methods should also be used against freezing.

Two or more of below protection methods should be considered when designing the system as a whole:

• Continuous water flow circulation inside piping and exchangers
  – Addition of an appropriate amount of glycol inside the water circuit
  – Additional heat insulation and heating of exposed piping
• Emptying and cleaning of the heat exchanger during the winter season

It is the responsibility of the installer and/or of local maintenance personnel to ensure that described anti-freeze methods are used. Make sure that appropriate anti-freeze protection is maintained at all times. Failing to follow the instructions above could result in unit damage. Damage caused by freezing is not covered by the warranty.

Installing the flow switch

To ensure sufficient water flow through the evaporator, it is essential that a flow switch be installed on the water circuit. The flow switch can be installed either on the inlet or outlet water piping. The purpose of the flow switch is to stop the unit in the event of interrupted water flow, thus protecting the evaporator from freezing.

The manufacturer offers, as optional, a flow switch that has been selected for this purpose.

This paddle-type flow switch is suitable for heavy-duty outdoor applications (IP67) and pipe diameters in the range of 1" to 6". The flow switch is provided with a clean contact which must be electrically connected to terminals shown in the wiring diagram.

Flow switch has to be tune to intervene when the evaporator water flow is lower than 50% of nominal flow rate.

Heat recovery

Units may be optionally equipped with heat recovery system. This system in made by a water cooled heat exchanger located on the compressors discharge pipe and a dedicated management of condensing pressure.

To guarantee compressor operation within its envelope, units with heat recovery cannot operate with water temperature of the heat recovery water lower than 28^ C.

It is a responsibility of plant designer and chiller installer to guarantee the respect of this value (e.g. using recirculating bypass valve)

Electrical Installation

General specifications

All electrical connections to the unit must be carried out in compliance with laws and regulations in force.
All installation, management and maintenance activities must be carried out by qualified personnel.
Refer to the specific wiring diagram for the unit you have bough. Should the wiring diagram not be on the unit or should it have been lost, please contact your manufacturer representative, who will send you a copy. In case of discrepancy between wiring diagram and electrical panel/cables, please contact the manufacturer representative.

Only use copper conductors. Failure to use copper conductors could result in overheating or corrosion at connection points and could damage the unit.

To avoid interference, all control wires must be connected separately from the power cables. Use different electrical passage ducts for this purpose.

Before servicing the unit in any way, open the general disconnecting switch on the unit's main power supply.

When the unit is off but the disconnecting switch is in the closed position, unused circuits are live, as well.

Never open the terminal board box of the compressors before having opened the unit's general disconnecting switch.

Contemporaneity of single-phase and three-phase loads and unbalance between phases could cause leakages towards ground up to 150mA, during the normal operation of the units of the series.

If the unit includes devices that cause superior harmonics (like VFD and phase cut), the leakage towards ground could increase to very higher values (about 2 Ampere).

The protections for the power supply system have to be designed according to the above mentioned values.

Operation

Operator's responsibilities

It is essential that the operator is appropriately trained and becomes familiar with the system before operating the unit. In addition to reading this manual, the operator must study the microprocessor operating manual and the wiring diagram in order to understand start-up sequence, operation, shutdown sequence and operation of all the safety devices.

During the unit's initial start-up phase, a technician authorized by the manufacturer is available to answer any questions and to give instructions as to the correct operating procedures.

The operator must keep a record of operating data for every installed unit. Another record should also be kept of all the periodical maintenance and servicing activities.

If the operator notes abnormal or unusual operating conditions, he is advised to consult the technical service authorized by the manufacturer.

If all power to the unit is turned off, the compressor heaters will become inoperable. Once power is resumed to the unit, the compressor and oil separator heaters must be energized a minimum of 12 hours before attempting to start the unit.

Failure to do so can damage the compressors due to excessive accumulation of liquid in the compressor.

Routine maintenance

Minimum maintenance activities are listed in

Table 2
