Page 15: Outdoor Unit Installation (Top Discharge Unit)
OUTDOOR UNIT INSTALLATION (Top Discharge Unit) 1. Location selection Before starting the installation, select and check the suitability of the location for both the indoor and outdoor unit. Observe all limitations and clearance requirements. The outdoor unit must have sufficient clearance for air entrance to the condenser coil, for air discharge and for service access. - Page 16 Normal operating sound levels may be objectionable if the unit is placed directly under windows of certain rooms (bedrooms, study, etc .). Top of unit discharge area must be unrestricted for at least 6 feet above the unit. Warning: The outdoor unit should not be installed in an area where mud or ice could cause personal injury. Elevate the unit sufficiently to prevent any blockage of the air entrances by snow in areas where there will be snow accumulation.
