STORAGE

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 recommend ap-
plying 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 films.
•   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 affect 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 
86.6 in/s).

•  The soil under the unit must be flat, smooth and sufficiently 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.

•   Stationary appliance: 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 flexible couplings. The anti-vibration 

supports must be fixed to the unit BEFORE it is earthed. AERMEC is not 

responsible for the choice of capacity of the anti-vibration supports.

•    For installation on vibration dampers:

  The unit must be fixed to the anti-vibration supports and these firmly fixed 

to the concrete base, see chapter weight distribution and minimum technical 
spaces

•   For installation without vibration dampers:

 fix the unit to the base using 

screws with the necessary resistance

•  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 flat on the base surface.

•   It is essential that the units are installed leaving sufficient space around them 

to allow easy access to the components for maintenance and repair purposes. 

•   Unit for installation at max. 2000m a.s.l.

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

installation of the unit invalidates the warranty.
