Unit Hand Ð When facing the supply air outlet from the front of the unit (air blow- ing in your face), your right hand will be the right hand side of the unit and your left hand the left hand side of the unit.

Same End Connection (2 Pipe or 4 Pipe) Ð All piping connections are on the same end (side) of the unit. Controls and electrical connection will be on the end (side) opposite the piping connection.

Standard 2-pipe units will be the same end connection.

NOTE: Piping determines the hand of the unit.

Opposite End Connection (4-Pipe Option) Ð Hot water (HW) piping connections and electrical will be on the end (side) opposite the chilled water (CW) and drain connections.

NOTE: Chilled water piping determines the hand of the unit.

Valve Packages For 2-Pipe Systems Ð Valve packages for standard 2-pipe units are piped for same end connection (L.H. or R.H.).

Valve Packages for 4-Pipe Systems - Select 2 valve packages per unit.

NOTE: Hot water valve package requirements may not be the same as chilled water valve package!
