This document provides installation and maintenance instructions for the R-410A Single Package Electric Cooling unit, models PAD324-60 (1 & 3 Phase). These units are fully self-contained and designed for outdoor installation, suitable for either rooftop or ground-level cement slab mounting. They feature discharge openings for both horizontal and downflow duct configurations, with downflow openings covered at the factory.
The R-410A Single Package Electric Cooling unit is designed to provide cooling for residential and non-residential applications. It integrates a compressor, condenser, evaporator, and fan components into a single outdoor unit. The unit can be configured for single-speed cooling or two-speed cooling with an enhanced dehumidification feature, depending on the thermostat or dehumidistat used. It also supports the installation of accessory electric heaters for heating functionality.
The manual provides detailed physical data for various unit sizes (24, 30, 36, 42, 48, 60), including:
The unit requires a separate electrical service with a field-supplied, waterproof disconnect switch. High-voltage connections are made to the compressor contactor, and low-voltage connections (no. 18 AWG or no. 16 AWG for runs over 100 ft) are made to the thermostat and indoor fan board. Three-phase scroll compressors are direction-oriented and require correct 3-phase power lead orientation for proper operation.
