1 - SAFETY CONSIDERATIONS
1.1 - General
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,
start-up or service air conditioning equipment.
Only authorised, trained and qualified technicians should be
allowed to carry out work on the electrical or refrigerant
components.
Untrained personnel can perform the basic maintenance
functions such as cleaning the outside of the unit (without
pressing on the control). All other functions, such as cleaning
of the outside of the remote control, cleaning of the unit
interior, checking the cut-out devices of the installation etc.
must be done by qualified service personnel.
When working on air conditioning equipment, observe
precautions in 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 on the unit, turn off the main power switch to the
unit. Electrical shock could cause personal injury.
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
o
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.
ATTENTION: Even if the compressor motors have been
switched off, the power circuit remains energized, unless the
unit or circuit disconnect switch is open. Refer to the wiring
diagram for further details.
Attach appropriate safety labels.
