Refrigerant Pipe Connection - Kelvinator KSV25CRG Installation Manual

Outdoor unit installation

Refrigerant pipe connection

NOTE:
• The connectors used to join the indoor and outdoor
refrigeration pipes must be located outside. They cannot be
located inside or within a wall cavity where refrigerant may
build up in the case of a leak.
• Refrigeration pipe length will affect the capacity and energy
efficiency of the unit. The nominal efficiency is tested based on
the pipe length of 5 meters.
• If the installation requires pipe length greater than the
standard 5m, then add additional refrigerant according to the
below table, which also indicates the maximum pipe length
and maximum height difference between indoor and outdoor
units.
• Please also refer to the below table for discharge and suction
pipe diameter.
