Installation Procedure
1. Positioning for Installation
The valve should be connected to the liquid tube.
Determine the position for installation referring to the
diagram of outer dimensions. (Fig. 2-163)
Refrigerant-flow noise may occur from the external
electronic expansion valve. As a guide, the distance
from the indoor unit should be a minimum of 5 m,
but less than 8 m. (Install away from locations where
strictly quiet operation is required.) If this distance is
unavailable, install inside the ceiling or in another
location where noise insulation is possible.
This is a functional component, and therefore may
require inspection and replacement.
Consider this when deciding the installation location.
(For example, place near an inspection port, or provide one.)
This valve is for indoor use. Do not install the valve outdoors.
