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 per- formed 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 ATTENTION When having to take measurements with the machine on and the electrical 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.

The measurements of the compressor inlet and outlet temperature and pressure to determine the overheating and subcooling of the machine, must be carried out as follows: With machine off, access its cooling circuit; Connect the necessary instruments, • Pressure gauges connected through appropriate extensions to the compressor inlet and outlet pressure plugs; • Thermometers connected to thermocouple probes that are fixed to the compressor inlet and outlet pipes. Avoid using metratast that require the opera- tor to near the machine cooling circuit; - Access the machines and acquire the measurements, keeping AWAY from the under pressure parts of the cooling circuit; - As soon as the measurements are taken, turn off the machine, remove the instruments and close the cooling circuit compartment. The high/low pressure switch, where present must be tested with the machine “closed”, reading the high pressure circuit pressure on the machine control panel. In case of machines with the cooling circuit compartment not closed by framework, the high/low pressure switch must be tested by standing in front of the machine panel where the control panel is located, remaining distant and not exposed to the under pressure parts of the cooling circuit.
