Location
This unit is intended for indoor installation only. It is highly recommended that this indoor unit and accessories, particularly

into consideration the minimum service access clearances provided in the unit drawings.
Locate the indoor unit away from the areas where noise is a critical factor. Use rubber mounting pad (not supplied) in order
to minimize the transfer of noise and vibration into building structures.
An optional hanging bracket assembly and rubber grommet (supplied as standard with SRV231E and SRM231E)
