lead to risk of burns by contact;

•  Do not use your hands to control any refrigerant leaks;

•  Before removing elements along the under pressure hydronic circuits, 

shut-off the pipe section involved and gradually drain the fluid until 

its pressure and that of the atmosphere are balanced.

PREVENTION AGAINST RESIDUAL ELECTRICAL RISKS

•  Before  opening the electrical panel, disconnect the unit from the 

mains by means of the external isolator;

•  If  the unit has power factor correction condensers, wait the time 

indicated on the machine plate from when the power supply was 

disconnected from the unit before accessing inside the electrical 

panel;

•  If  the unit is equipped with integrated inverter type 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.

•  If  the power supply cable is damaged, it must be replaced by the 

manufacturer, After Sales Service or by another similarly qualified 

person, to avoid dangerous situations.

CLEANING THE MACHINE

The machine must be turned off and electrically disconnected when being 
cleaned.

INSPECTION AND CONTROL

The machine must be turned off and electrically disconnected during its 
inspection and leak check.

ROUTINE AND EXTRAORDINARY MAINTENANCE

The machine must be turned off and electrically disconnected during its 
maintenance (with possible replacement of components). In particular:

•  Before any intervention, isolate the unit from the mains by means of 

the external isolator provided for the insertion of padlocks (up to 3) 

for blocking in ‘’open’’ position;

•  Place a sign reading ‘’Do not turn on – maintenance in progress’’ on 

the open isolator;

•  Equip yourself with tools in good condition and make sure to have 

fully understood the instructions before using them;

•  Equip yourself with the appropriate personal protective equipment 

as indicated in paragraph 1 of this report;

•  For  outdoor units, do not perform interventions in dangerous 

weather conditions such as rain, snow, fog, thunderstorms, etc;

•  The cooling circuit components must be replaced after draining the 

refrigerant gas contained in the circuit;

•  During  venting protect yourself against any leakage of fluids at 

dangerous temperatures and/or pressures;

•  Always use appropriate equipment (extractor, antistatic bracelet etc) 

when replacing electronic boards;

•  If  replacing a motor, compressor, evaporator, condensing coil or 

any other heavy element, make sure that the lifting devices are 

compatible with the weight to be handled;

•  In  air units with independent compressor compartment, do not 

access the fan compartment without having first disconnected the 

machine through the isolator on the board and having placed a sign 

reading ‘’Do not turn on – maintenance in progress’’;

•  Always  and only use original spare parts purchased directly from 

Aermec or from official dealers. Contact Aermec should it be 

necessary to move the unit one year after its positioning on-site or it 

must be dismantled;

•  It  is not permitted to change the refrigerant, hydraulic or electric 

layout of the unit, or its control logic unless expressly authorised by 

Aermec;

•  The machine must be loaded with the refrigerant in the feature label 

and in the required quantity;

•  Make sure to have removed all tools, electrical cables or other loose 

object and having perfectly connected the machine to the system 

before closing it and starting it;

•  The inspections and measurements necessary to establish the correct 

functioning of the machine to be run with the machine in operation, 

must be performed with the machine closed (framework fixed on 

the machine), reading the measurements collected by the control 

board and viewable in the control panel of the same. In the case of 

machines with cooling circuit compartment open, stand in front of 

the control panel of the electrical panel remaining distant and not 

exposed to the under pressure parts of the cooling circuit

•  If replacing a fuse or a circuit breaker, details relating the type and 

ratings of fuses or circuit breakers are visible in the mark inside the 

electrical panel.

ATTENTION

When having to take measurements with the machine on and the elec-

trical panel and cooling circuit open, be careful since the machine is 

live, the cooling circuit contains high pressure gas, the pipes may be 

hot or cold, some parts may be in motion. 

Any absorption measurements of the compressors, compressor casings, 

pumps and fans as well as the power supply measurements, must be taken 

as follows:

•  With machine off, access its panel;

•  Connect  the measuring instruments such as current clamps (to 

measure the current) and multimeters (to measure the voltage). 

These instruments must be fitted with appropriate terminals/clamps 

that allow to remotely control the measurement;

•  Access  the machine and read the measurements made by the 

instruments, keeping AWAY from live electrical parts;

•  As soon as the measurements are taken, turn off the machine, remove 

the instruments and close the electrical panel.
