Do not exceed the maximum allowable pressure (PS) of the unit’s

water circuit shown on the serial number plate

- Before removing elements along the under pressure water circuits,

shut-o the pipe section involved and gradually drain the uid until

its pressure and that of the atmosphere are balanced.

- The unit contains under pressure refrigerant gas: no operation

must be performed on under pressure equipment except during

maintenance that must be carried out by competent and authorised

personnel

- Perform brazing or welding only on empty pipes and clear of any

lubricating oil residues; do not near ames or other heat sources to

the pipes containing refrigerant uid

- Do not work with naked ames near the unit

- In order to avoid an environmental risk, make sure that any uid leaks

are recovered in suitable devices in compliance with local regulations.

- Do not use your hands to control any refrigerant leaks

- An accidental release of refrigerant may cause risk of suocation

due to a lack of oxygen: install the machine in a well ventilated

environment in accordance with EN 378-3 and local regulations

currently in force. Those who come into contact with the machine

must be equipped with a leak detector that is calibrated and

validated to reveal any used refrigerant leaks.

- The unit is tted out with overpressure relief devices (safety valves):

in the event that these devices start, the refrigerant gas is released at

high temperature and high velocity.

Prevent the gas ow from harming people or things; if necessary,

channel the leak according to the EN 378-3 standard and local

regulations currently in force, paying particular attention to channel

uids that pertain to safety groups other than A1 toward open and

secure spaces.

- Keep all lubricants in properly marked containers do not keep

ammable liquids near the plant

mains by means of the external isolator

- In case of units with shunt capacitors, wait 3 minutes from when

power supply was disconnected from the unit before accessing inside

the electrical panel

- If the unit is equipped with integrated inverter compressors,

disconnect the power supply and wait at least 15 minutes before

accessing for maintenance: the internal components remain live for

this time, generating the risk of electrocution

- The safety devices must be maintained ecient and periodically

checked as prescribed by current regulations

- In case a piece is disassembled, make sure it is correctly reassembled

before restarting the unit

- Even with the unit o, prevent the uid in contact with the

- Make sure that the protections of mobile elements are correctly in

place before restarting the unit

- Fans, motors and belt drives may be in motion: always wait for them

to stop and take appropriate precautions to prevent their activation

before accessing them

- the machine and the pipes have very hot and very cold surfaces that

lead to risk of burns

- Before opening a machine panel, ascertain whether it is or not rmly

connected to it by hinges

- Louvers of the heat exchangers, edges of the components and metal

panels can generate cuts

- The installation must ensure that the temperature of the uid

entering the unit is maintained stable and within the provided limits;

therefore, pay attention to the adjustment of any external thermal

exchange and control devices (drycooler, evaporating towers,

area valves, ...), to the adequate dimensioning of the mass of uid

circulating in the plant (in particular when plant areas are excluded)

and to install systems for the recirculation of the necessary uid ow

rate so as to maintain the machine temperatures within the allowed

limits (e.g. during the start-up phase).

STORAGE

It may happen that, after receipt, the units are not to be immediately installed and are kept in storage. In case of medium-long term storage, we recom-

mend applying the following procedures:

• Make sure there is no water inside the hydraulic systems.

• Do not remove the protections from the heat exchanger.

• Do not remove the plastic protective lms.

• Make sure that the electrical panels are closed.

• Before using the equipment, store all items provided in a dry and clean place so that they can be used in the future. We recommend storing the unit in a

dry and sheltered place (especially for units intended for indoors).

NOTE The maximum storage temperature of the units depends on the type of refrigerant contained, see table. Beyond this limit, there is a risk of refrigerant

leaking through the safety valves.

plaCement anD installation reQuirements

For unit installation it is important to perform the following preliminary

preparation tasks:

• When installing, make sure that the atmospheric or environmental agents

do not aect and corrode the cooling circuit components, causing the

refrigerant to leak in the environment and, if so, make the appropriate

adjustments.

• The air-cooled units with fans are designed for outdoor installation.

Contact Aermec before making any type of installation.

• The water-cooled units are designed for indoor installation. Contact

Aermec before making any type of installation.

• For the positioning of the air-cooled units for outdoor use, choose a place

that is not exposed to excessive wind (install windbreaks if the wind speed

exceeds 86.6in/s).

• The soil under the unit must be at, smooth and suciently strong to

withstand the weight of the unit with a full refrigerant load, as well as the

occasional presence of the normal maintenance equipment.

• In locations exposed to frost, if the unit is installed on soil, the support

base must rest on concrete columns with a depth greater than the normal

depth of frost of the soil. It is always advisable to build a support base

separate from the main building to avoid the transmission of vibrations.

• For normal applications, the rigidity of the unit and the positioning of

point loads allow for an installation that minimises vibrations. In the case

of installations requiring particularly low vibration levels, you can use the

anti-vibration supports.

ATTENTION: The use of anti-vibration supports MUST be combined with

the installation in the unit water piping of exible couplings. The anti-

vibration supports must be xed to the unit BEFORE it is earthed. AERMEC

is not responsible for the choice of capacity of the anti-vibration supports.

• The unit must be xed to the anti-vibration supports and these rmly

xed to the concrete base, see chapter weight distribution and minimum

technical spaces

• Check that the contact surfaces of the anti-vibration supports are levelled

to the base. If necessary, use spacers or level the base but, in any case,

make sure that the anti-vibration supports rest at on the base surface.

• It is essential that the units are installed leaving sucient space around

them to allow easy access to the components for maintenance and repair

purposes.

ATTENTION: It is important that the units are installed at. The improper

installation of the unit invalidates the warranty.
