CONNECTING METHOD
Select and install the socket that matches the diameter of a pipe to be connected to the indoor unit
Gas side
Liquid side
-
If the number of indoor units to be connected is fewer than the maximum number of units that can be connected to the branching header, attach a sealed pipe to the unused connectors.
-
Install the branching header so that it branches horizontally.
Gas side
Liquid side
When arranging the branching header at the liquid side, attach a header sealed
pipe on the sealing side of the header as shown in the fiqure at right. Be
sure to install the branch pipe downward. Horizontal viewed from D point
should be within ±10 degrees same as view B.
- Supporting branching heade
After applying the insulation, set the hanging metals as support. (in use on the site)
NOTE :
- Install the branching header so that it branches horizontally. It cannot be used in a vertical position.
- Do not use T-type pipe for the branching section.
REQUIREMENT
Condensation may occur on the heat insulator according to the atmosphere
inside of the ceiling.
If the inside of the ceiling is subject to high temperature and high
humidity,please add the glass wool (16 to 20 kg/m3, 10mm thick or more) on the
heat insulator described above for the perfect heat insulation.
