Safety considerations
Norme di sicurezza
Installation and servicing of air conditioning
equipment can be hazardous due to system
pressure and electrical components. Only
trained and qualified service personnel
should install, repair or service air
conditioning equipment.
Untrained personnel can perform the basic
maintenance functions of cleaning coils and
filters, and replacing filters. All other
operations should be performed by trained
service personnel. When working on air
conditioning equipment, observe
precautions on the literature tags and labels
attached to the unit and other safety
precautions that may apply.
Follow all safety codes. Wear safety
glasses and work gloves. Use a quenching
cloth for unbrazing operations.
WARNING:
Before performing service or
maintenance operations turn off the
main power switch to unit. Electrical
discharge could cause personal injury.
Only for use when repairing Original
Spare Parts. Special attention must be
paid to positioning.
During unit operation, some of the
refrigerant circuit elements could reach
a temperature in excess of 70
°C so only
trained or qualified personnel should
access areas protected by access
panels. This unit should not be installed
in an explosive atmosphere.
IMPORTANT:
The manufacturer does not accept
responsibility for any malfunction
resulting from misuse of the equipment.
VERY IMPORTANT:
On heat pump Multi-split units, it is
advisable that all indoor units are always
working in the same cycle, COOLING or
HEATING cycle.
Le operazioni d’installazione, manutenzione
e riparazione di impianti di climatizzazione
possono risultare rischiose per la presenza
di pressione all’interno del sistema e dei
componenti elettrici. Tali operazioni devono
essere eseguite esclusivamente da
personale qualificato.
Personale non qualificato può effettuare
soltanto operazioni di manutenzione
ordinaria come ad esempio la pulizia delle
batterie e la sostituzione dei filtri.
Tutte le altre operazioni devono essere
eseguite da personale qualificato. Se si
lavora su un impianto di climatizzazione,
osservare le avvertenze riportate sulle
etichette o cartellini dell’unità e eventuali
altre norme di sicurezza.
Osservare tutte le misure di sicurezza.
Portare occhiali di protezione e guanti di
lavoro. Durante le operazioni di saldatura
utilizzare indumenti protettivi.
ATTENZIONE:
Prima di svolgere operazioni di manu-
tenzione e riparazione scollegare lunità
dallimpianto elettrico centrale. Eventuali
scariche elettriche potrebbero risultare
estremamente pericolose.
Durante le riparazione usare soltanto le
parti originali di ricambio. Si deve
prestare particolare attenzione alla
posizione.
Durante il funzionamento dellunità,
alcune parti del circuito refrigerante
possono raggiungere temperature
superiori a 70
°C, quindi solo personale
qualificato può operare su tali parti
protette da pannelli di accesso.
Questa unità non può essere installata
in unatmosfera esplosiva.
IMPORTANTE:
Il costruttore non si assume alcuna
responsabilità in caso di danni dovuti a
manomissioni o uso improprio dellunità.
MOLTO IMPORTANTE:
Nelle unità Multi-split a pompa di calore,
si consiglia di far funzionare tutte le
unità interne nel medesimo ciclo: in
riscaldamento o in raffrescamento.
