2. 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. 3-170) Refrigerant-ﬂ ow noise may occur from the external electronic expansion valve. As a

guide, the distance from the indoor unit should be a minimum of 16.4 feet, but less than 26.2 feet. (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.
