A minimum 14 inch clearance for servicing the unit is
required for all EXH 0.5 to 6 ton configurations from
other mechanical and electrical equipment (where
shown) to enable panel removal from the unit for
service/maintenance ability. The optimum clearance
required is 20 inches.
Equipment containing a same-side supply/return
combination requires a 3 inches limitation on one
side. Access to the TXV may not be possible with this
3 inches clearance. This configuration is typically
applied in a corridor installation, where space
limitations force the left or right side of the unit
against a wall.
