VERY IMPORTANT:
To prevent electrical shock or equipment damage, make
sure the power supply sectioners are open before electrical
connections are made.
If this action is not taken, personal injury may occur.
First make the refrigerant connections and then the
electrical ones. In the case of disassembly, operations must
be carried out in the opposite sequence.
WARNING:
Operation of unit on improper line voltage constitutes
abuse and is not covered by Carrier warranty.
IMPORTANT:
• The mains supply indoor unit – outdoor unit connecting
cable must be H07 RN-F (60245IEC66) type synthetic rubber
insulation with neoprene coating.
Consult the wiring diagram sent with the outdoor unit.
• To effect the unit power supply (wire inlet, conductor
section, protections, etc..), consult the Electrical Data
Table, the wiring diagram sent with the unit and the
standards in force affecting the installation of air
conditioning equipment.
• To connect a condensate drainage pump follow the wiring
diagram instructions in the next pages.
VERY IMPORTANT:
The installer should place protection elements in the line
according to the legislation in force.
IMPORTANT:
• Make ground connection prior to any other electrical
connections.
• Make electrical connections between units prior to proceeding
to mains supply unit connection.
• According to the installation instructions, the disconnecting
switches from the mains power supply should have a contact gap
(4 mm) such that total disconnection can be ensured under the
conditions provided for by overvoltage class III.
NOTE:
• All field electrical connection are the responsibility of the
installer.
