SAFETY PRECAUTIONS
•
Installation and maintenance of air conditioning equipment can be dangerous because the
system is under pressure, because some of its elements have high temperatures and include
electrical components.
•
Only qualified and trained service staff should install, commission and carry out maintenance
works. Unqualified staff should only carry out basic tasks such as cleaning and replacement of
filters, etc.
•
In every visit, all precautions should be taken into account: those recommended in the
Installation, operation and maintenance instructions, as well as the ones indicated in labels of
the unit. Do not forget to strictly follow any other safety codes.
•
Use safety glasses, work gloves and any other safety accessory necessary.
•
For brazing operations use a quenching cloth and have at close distance a fire extinguisher.
WARNING!
Before starting installation, service or maintenance, turn off the main power switch in order to
avoid electrical shock that may cause personal damages.

position where old parts were placed.
