Connecting the Refrigerant Piping

1. Piping Installation of refrigerant piping is possible as front connection, side connection and bottom connection.
Installation
Caution Be sure to use the attached pipe when carrying out piping work in the field.
Separately use the optional "KHF30A30L" or "KHF30A30U" piping kit when carrying out connections for
the side and bottom on RSXYP24, 26, 28, and 30.
Connect the flange on the valve on the gas side before connecting the flare nut on the valve on the
liquid side.
(Connecting the liquid side first will make it harder to connect the gas side.)
Be sure that the local piping does not touch other pipes, the bottom panel or side panel. Especially
for the bottom and side connection, be sure to protect the gas piping with the provided insulation,
to prevent it from coming into contact with the casing.
RSXYP16,18,20
RSXYP24,26,28,30
Notes: 1. Front Connection
2. Side Connection
Refer the optional "KHF30A30L" or "KHF30A30U" piping kit on page 104 for more detail.
