• Placement on a level surface free of obstructions (including snow, for winter operation) or air
recirculation ensures rated performance, reliable operation and ease of maintenance.
• Site restrictions may compromise minimum clearances, resulting in unpredictable air flow
patterns and possible reduced performance.
• The distances between the walls and peripheral units must employ the same rules as shown in
location clearances if the units are surrounded by walls.
• No more than one adjacent wall may be higher than the unit.
• The installing contractor must include vent and drain connections in the water piping near the
heat exchanger.
• Balancing valves must be installed at the inlet of each unit to balance chilled liquid distribution.
• A minimum space of 48 in. (1,220 mm) for R-454B units must be reserved for field wiring,
commissioning and maintenance in case of control panel face to face installation.
• Refer to the single module and modular array drawings for detailed dimensions.
