SAFETY CONSIDERATIONS
Installation and servicing of air conditioning equipment can be

Only trained and qualified service personnel should install,
start-up or service air conditioning equipment. Untrained
personnel can perform the basic maintenance functions of

All other operations should be performed by trained service
personnel.
When working on air conditioning equipment, observe

Follow all safety codes. Wear safety glasses and work gloves.
Use a quenching cloth for unbrazing operations.
WARNING: Before performing service or maintenance
operations on the unit, turn off the main power switch to the
unit. Electrical shock could cause personal injury.
All units are designed for ducted installation (indoor and/or
outdoor air discharge). If ducts are not used the installer must
place a protection grille in the discharge.
Only for use when repairing "Original Spare Parts". For
repairs, special attention must be paid to the correct
installation of the spare parts. The parts must always be
installed in their original position.
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.
The unit can operate in normal radioelectric atmospheres in
residential, commercial and light industrial installations. For
other applications, please consult Carrier.
