2 Shipping Inspection Always transport the unit upright; laying the unit on its side or top during transit may cause equipment damage. The installer should inspect the product upon receipt for shipping damage and subsequent investigation is the responsibility of the carrier. -
Page 4: Clearances
5.4 Clearances The unit clearance from a combustible surface may be 0". However, service clearance must take precedence. A minimum of 24" in front of the unit for service clearance is required. Additional clearance on one side or top will be required for electrical wiring connections. -

6.4 Horizontal Right Installation Side drainpan extension must be removed for all models except : ARUF47D14**, ARUF61D14**, ASPT61D14**. Refer to Figure 6 and 7 for the location of the components referenced in the following steps. 1. Before inverting the air handler, remove blower access panel and coil access panel. The coil access panel and tubing panel may remain screwed together during this procedure. - Page 6 Blower Access Panel Secondary Drain Port Horizontal Application Tubing Panel Secondary Drain Port for Upflow/Downflow Application INTERNAL PART TERMINOLOGY EXTERNAL PART TERMINOLOGY Figure 6 Figure 7 Coil Slides on the downflow bracket IMPORTANT NOTE: ACCESS PANEL CONFIGURATION FOR DOWNFLOW Ensure coil slides on the rails along the groove provided on the drain pan side OR HORIZONTAL RIGHT walls.

Page 9: Ductwork
A drain trap in a draw-through application prevents air from being drawn back through the drain line during fan opera- tion thus preventing condensate from draining, and if connected to a sewer line to prevent sewer gases from being drawn into the airstream during blower operation. - Page 10 NOTE: The Temperature Rise Tables can also be used to estimate the air handler airflow delivery. When using these tables for this purpose set the room thermostat to maximum heat and allow the system to reach steady state conditions. Insert two thermometers, one in the return air and one in the supply air. The temperature rise is the supply air temperature minus the room air temperature.
