Decommissioning
On the schedule keep track of:
• The date;
• The intervention description;
• The carried out measures.
11.2
Circulation pumps
Please check:
• If there is no leaks;
• Bearing status (anomalies are highlighted by abnormal noise and
vibration);
• The closing of terminal covers and the correct positioning of the cable
glands.
Insulations
Check the condition of the insulations and, if necessary, apply glue and
renew the seals.
Safety valve
The pressure relief valve must be replaced:
• If it has intervened;
• If there is oxidation;
• Based on the date of manufacture, in compliance with local
regulations.
11.3
Air coil
CAUTION
Accidental contact with the exchanger fins.
Can cause serious cuts.
▶ Wear protective gloves
The coil must allow maximum thermal exchange, therefore, the surface
must be clear from dirt and scaling. It is recommended a quarterly
cleaning of the coils, as the minimum.
The cleaning frequency should be increased depending on the level of
dirt/dust accumulation and the environment (e.g., coastal areas with
chlorides and salts) or industrial areas with aggressive substances.
Shut down periods
During periods when the unit is not operated for longer than a week, the
coil must be completely cleaned following the cleaning procedure.
Cleaning procedure
Relative to tube and fin heat exchangers, these coils tend to accumulate
more dirt on the surface of the coil and less dirt inside the coil, making
them easier to clean. Follow the steps below for proper cleaning:
• Remove surface debris
– Remove surface dirt, leaves, fibres, etc. with a vacuum cleaner
(preferably with a brush or other soft attachment rather than a
metal tube), compressed air blown from the inside out, and/or a
soft bristle (not wire!) brush. Do not impact or scrape the coil.
• Rinse only with water
– Do not use any chemicals to clean heat exchangers, as they may
cause corrosion.
– Hose off gently, preferably from the inside-out and top to bottom,
running the water through every fin passage until it comes out
clean.
– The fins are stronger than others coil fins but still need to be
handled with care. Do not hit the coil with the hose.
– It is not recommended using a pressure washer to clean the coil
due to the possibility of damage. Warranty claims related to
cleaning damage, especially from pressure washers, or corrosion
resulting from chemical coil cleaners, will not be honoured.

Decommissioning
Disconnection
Before performing any operation, read the Maintenance chapter.
Avoid leak or spills into the environment.
Before disconnecting the unit, the following must be recovered, if
present:
• Refrigerant gas;
• Anti-freeze solutions in the hydraulic circuit.
Awaiting decommissioning and disposal, the unit can also be stored
outdoors, as bad weather and rapid changes in temperature do not harm
the environment provided that the electric, refrigerant and hydraulic
circuits of the unit are intact and closed.
WEEE Information
The manufacturer is registered on the EEE National Register, in
compliance with implementation of Directive 2012/19/EU and relevant
national regulations on waste electrical and electronic equipment.
This Directive requires electrical and electronic equipment to be
disposed of properly.
Equipment bearing the crossed-out wheelie bin mark must be disposed
of separately at the end of its life cycle to prevent damage to human
health and to the environment.
Electrical and electronic equipment must be disposed of together with
all of its parts.
To dispose of "household" electrical and electronic equipment, the
manufacturer recommends you contact an authorised dealer or an
authorised ecological area.
"Professional" electrical and electronic equipment must be disposed of
by authorised personnel through established waste disposal authorities
around the country.
In this regard, here is the definition of household WEEE and professional
WEEE:
WEEE from private households: WEEE originating from private
households and WEEE which comes from commercial, industrial,
institutional and other sources which, because of its nature and quantity,
is similar to that from private households. Subject to the nature and
quantity, where the waste from EEE was likely to have been by both a
private household and users of other than private households, it will be
classed as private household WEEE;
Professional WEEE: all WEEE which comes from users other than private
households.
This equipment may contain:
• Refrigerant gas, the entire contents of which must be recovered in
suitable containers by specialised personnel with the necessary
qualifications;
• Lubrication oil contained in compressors and in the cooling circuit to
be collected;
• Mixtures with antifreeze in the water circuit, the contents of which are
to be collected;
• Mechanical and electrical parts to be separated and disposed of as
authorised.
When machine components to be replaced for maintenance purposes
are removed or when the entire unit reaches the end of its life and needs
to be removed from the installation, waste should be separated by its
nature and disposed of by authorised personnel at existing collection
centres.
