SAFETY CONSIDERATIONS
Installing, starting up, and servicing air-conditioning equipment
can be hazardous due to system pressures, electrical components,
and equipment location.
Only trained, qualified installers and service mechanics should
install, start-up, and service this equipment.
Untrained personnel can perform basic maintenance functions,
such as cleaning coils. All other operations should be performed
by trained service personnel. Qualified installers and service tech
-
nicians are required to have been trained on the following topics
when installing and servicing air-conditioning equipment with
A2L refrigerant such as R-32:
1. Explosive potential of A2L refrigerants.
2. Potential ignition sources.
3. Safety measures for unventilated and ventilated rooms or
enclosures.
4. Refrigerant detectors.
5. Concept of sealed components and sealed enclosures
according to IEC 60079-15:2010.
6. Correct work procedures for the following:
a. Commissioning
b. Maintenance
c. Repair
d. Decommissioning
e. Disposal
See Controls and Troubleshooting Guide for complete guidelines.
When working on the equipment, observe precautions in the
literature and on tags, stickers, and labels attached to the
equipment.
1. Follow all safety codes.
2. Keep quenching cloth and fire extinguisher nearby when
brazing.
3. Wear safety glasses and work gloves.
4. Use care in handling, rigging, and setting bulky equipment.
It is important to recognize safety information. This is the safety-
alert symbol
. When you see this symbol on the unit and in in-
structions or manuals, be alert to the potential for personal injury.
Understand the signal words DANGER, WARNING, CAUTION,
and NOTE. These words are used with the safety-alert symbol.
DANGER identifies the most serious hazards which will result in
severe personal injury or death. WARNING signifies hazards
which could result in personal injury or death. CAUTION is used
to identify unsafe practices, which may result in minor personal
injury or product and property damage. NOTE is used to highlight
suggestions which will result in enhanced installation, reliability,
or operation.
