Trane RT-PRC005 Application Considerations, Low Ambient Cooling, Barometric Relief, Unit Pitch

Application Considerations

Application of this product should be within the cataloged airflow and cooling considerations.

Low Ambient Cooling

The Precedent™ line features, with ReliaTel™ microprocessor controls, low ambient cooling down to 0F. With electromechanical controls, Precedent features low ambient cooling to 40F. Contact your localTrane Representative for more assistance with low ambient cooling applications.

Barometric Relief

This product line offers an optional barometric relief damper. for use in conjunction with economizer option. This accessory consists of gravity dampers which open with increased pressure. As the building air pressure increases, the pressure in the unit return air section also increases, opening the dampers and relieving the conditioned space.

NOTE:THE EFFECTIVENESS OF BAROMETRIC RELIEF DAMPER DURING ECONOMIZING OPERATION IS SYSTEM RELATED.

PRESSURE DROP OFTHE RETURN AIR SYSTEM SHOULD BE CONSIDEREDTO CONTROL BUILDING PRESSURIZA- TION.

CondensateTrap

The evaporator is a draw-thru configuration. A trap must be field provided prior to start-up on the cooling cycle.

Clearance Requirements

The recommended clearances identified with unit dimensions should be maintained to assure adequate service maximum capacity and peak operating efficiency. Actual clearances which appear inadequate should be reviewed with the localTrane sales personnel.

Unit Pitch

These units have reversible sloped condensate drain pans. Units must be installed level, any unit slope must be toward the side of unit where condensate drain is connected.
