Mechanical Installation

D-EIMWC00504-14EN - 18/68

Shipping

The stability of the machine during shipping must be ensured. If the machine is shipped with a wooden cross-plank on its base, the cross-plank must be removed only after the final destination has been reached.

Responsibility

The manufacturer declines all responsibility, present and future, for any damage to persons, animals or property caused by negligence of operators failing to follow the installation and maintenance instructions in this manual. All safety equipment must be regularly and periodically checked in accordance with this manual and with local laws and regulations regarding safety and environment protection.

Safety

The machine must be firmly secured to the ground. It is essential to observe the following instructions:

- The machine can only be lifted using the lifting points on the base of the machine itself. These are the only points that

can support the entire weight of the unit.

- Do not allow unauthorised and/or unqualified personnel to access the machine.

- It is forbidden to access the electrical components without having opened the machine's general disconnecting 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.

- All operations on the refrigerant circuit and on components under pressure must be carried out by qualified personnel

only.

- Replacement of a compressor or addition of lubricating oil must be carried out by qualified personnel only.

- Sharp edges can cause wounds. Avoid direct contact.

- Avoid introducing solid bodies into the water pipes while the machine is connected to the system.

- A mechanical filter must be installed on the water pipe connected to the heat exchanger inlet.

- The machine is supplied with safety valves, that are installed on both the high and the low pressure sides of the

refrigerant circuit. In case of sudden stop of the unit, follow the instructions on the Control Panel Operating Manual which is part of the on-board documentation delivered to the end user with this manual. It is 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

- 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 if the Health Emergency Service

- wait without leaving the injured person alone until the rescue operators come

- give all necessary information to the the rescue operators

WARNING

Before carrying out any operation on the machine, please read this instruction and operating manual carefully. Installation and maintenance must be carried out only by qualified personnel that is familiar with the provisions of law and local regulations and has been trained properly or has experience with this type of equipment.

WARNING

Avoid installing the machine in a place that could be dangerous during maintenance operations, such as (but not only) platforms without parapets or railings or areas not complying with the clearance requirements.

Moving and lifting

Avoid bumping and/or jolting during unloading from the lorry and moving the machine. Do not push or pull the machine from any part other than the base frame. Secure the machine inside the lorry to prevent it from moving and causing damage to the panels and to the base frame. Do not allow any part of the machine to fall during transportation and/or unloading, as this could cause serious damage. All units of the series are supplied with four lifting points. Only these points may be used for lifting the unit, as shown in figure 2.

D–EIMWC00504-14EN - 19/68

Fig. 2 - Lifting the unit

WARNING

Both the lifting ropes and the spacing bar and/or scales must be strong enough to support the machine safely. Please check the unit’s weight on the machine’s nameplate. The weights shown in the "Technical data" tables in the "General Information" chapter refer to standard units. Some specific machines might have accessories that increase their overall weight (heat recovery, etc.)

WARNING

The machine must be lifted with the utmost attention and care. Avoid jolting when lifting and lift the machine very slowly, keeping it perfectly level.

Positioning and assembly

All units are designed for installation indoors. The machine must be installed on a robust and perfectly level foundation; should the machine be installed on balconies or roofs, it might be necessary to use weight distribution beams. For installation on the ground, prepare a strong cement base that is at least 250 mm wider and longer than the machine. Also, this base must be strong enough to support the weight of the machine as stated in the technical specifications. If the machine is installed in places that are easily accessible to people and animals, it is advisable to install protection gratings for the compressor section. To ensure the best possible performance on the installation site, the following precautions and instructions must be followed:

• Make sure to provide a strong and solid foundation to reduce noise and vibration as much as possible.

D-EIMWC00504-14EN - 20/68

• The water in the system must be particularly clean and all traces of oil or rust must be removed. A mechanical water

filter must be installed on the machine’s inlet piping.

Minimum space requirements

Every side of the machine must be accessible for all post-installation maintenance activities. Figure 3 shows the minimum space necessary.

Fig. 3 – Minimum clearance requirements for machine maintenance

Ventilation

The temperature of the room where the unit is placed should be always maintained between 0°C and 40°C.

Sound protection

When sound levels require special control, great care must be exercised to isolate the machine 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-vibration mountings in order to reduce transmission of vibrations to the underlying structure.

2. Isolating valves to isolate the machine from the water system during service.

Manual or automatic air venting device at the system’s highest point; drain device at the system’s lowest point. Neither the evaporator nor the heat recovery device must be positioned at the system’s highest point.

4. A suitable device that can maintain the water system under pressure (expansion tank, etc.)

5. Water temperature and pressure indicators on the machine to assist the operator during service and maintenance.

A filter or device which can remove foreign particles from the water before it enters the pump (in order to prevent cavitation, please consult the pump manufacturer for the recommended type of filter ). The use of a filter prolongs the life of the pump and helps keep the water system in a better condition.

Another filter must be installed on the machine inlet water pipe, near the evaporator and heat recovery (if installed). The filter prevents solid particles from entering the heat exchanger, as they could damage it or reduce its heat exchanging capacity.

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

If the machine is intended to replace of another, 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 machine.

10.

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

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