Provide Vertical Clearance

Vertical condenser air discharge must be unobstructed. While it is difficult to predict the degree of warm air circulation, a unit installed as shown on the left would have its capacity and efficiency significantly reduced. Performance data is based on free air discharge.

c

Provide Lateral Clearance

The condenser coil inlet must not be obstructed. A unit installed closer than the minimum recommended distance to a wall or other vertical riser may experience a combination coil starvation and warm air recirculation, resulting in unit capacity and efficiency reductions. Once again, the Adaptive Control™ microprocessor will allow the chiller to stay on line, producing the maximum available capacity, even at less than recommended lateral clearances.

The recommended lateral clearances are depicted in the dimensional data section. These are estimates and should be reviewed with the local Trane sales engineer at the jobsite.

d

Provide Sufficient Unit-to-Unit Clearance

Units should be separated from each other by a sufficient distance to prevent warm air recirculation or coil starvation. The air-cooled Series R^® chiller has the lowest recommended unit-to-unit clearance in the industry, eight feet. Consult the local Trane sales engineer for applications concerning close spacing and restricted airflows.

e

Walled Enclosure Installations

When the unit is placed in an enclosure or small depression, the top of the fans should be no lower than the top of the enclosure or depression. If they are, consideration should be given to ducting the top of the unit. Ducting individual fans, however, is not recommended. Such applications should always be reviewed with the local Trane sales engineer.
