3 DESCRIPTION Both the outdoor and indoor units are completely piped and wired at the factory and are shipped ready for immediate installation. Only the interconnecting liquid and suction lines, control wiring, and the main power wiring are required to complete the installation. Every outdoor unit is dehydrated, evacuated, leak tested and pressure tested at 450 psig before being pressurized with a holding charge of refrigerant- 22 for shipment and/or storage. To eliminate the costly cabinet deterioration problems usually associated with outdoor equipment, all sheet metal parts are constructed of commercial grade (G90) galvanized steel. After fabrication, each part is thoroughly cleaned to remove any grease or dirt from its surfaces. The parts that will be exposed to the weather are then coated with a desert sand powder paint to assure a quality finish for many years. This coating system has passed the 750-hour, salt spray test per ASTM Standard B117. APPLICATION FLEXIBILITY OUTDOOR The outdoor units are lightweight and can be installed on almost any roof. Units can be lifted using nylon straps with hooks at the holes provided in the base rails, or they may be lifted with a forklift through the slotted openings in the base rails. A quality appearance and low sound levels make these units suitable for most ground level locations.

These units can be installed in either the vertical or horizontal position for maximum flexibility. NOTE: On vertical applications, the air velocity across the indoor coil keeps the condensate from dripping off the finned surface onto the filters: NOTE: On horizontal applications the unit must be installed with the condensate drain pan under the entire indoor coil. NOTE: The Supply Air Plenum and the Return Air Grille accessories can be used on either arrangement. NOTE: TheBaseaccessorycanonlybeusedonthevertical arrangement.

FIGURE 2 : OUTDOOR UNIT OUTDOOR PRODUCT NOMENCLATURE Every unit includes 2 heavy-duty scroll compressors, 2 outdoor fan motors with inherent protection, subfusing and a copper tube/aluminum fin coil. All controls are located in the front of the unit in the control box and are readily accessible for maintenance, adjustment and service. All wiring (power and control) can be made through the front of the unit. ACCESSORIES (FACTORY & FIELD INSTALLED Factory installed Non-Fused Disconnect for safety and convenience. Factory installed Technicoat Condenser Coils for corrosion protection. Field Installed VFD (Variable Frequency Drive) for Low Ambient operation down to 0ºF. Field Installed Hot Gas Bypass for low load operation. Field installed Pump-Out Kit for applications where liquid slugging could be an issue. 4 Unitary Products Group

FIGURE 3 : INDOOR PRODUCT NOMENCLATURE INDOOR UNIT Every unit includes a well-insulated cabinet, copper tube/aluminum fin coil with interlaced circuiting arrangement, 2" throwaway filters, adjustable TXV s and centrifugal blowers. Blower motors and drive kits are ordered separately. The controls include 208/230/460 volt transformer, blower motor contactor and relay, and a low voltage terminal block. The units are shipped in the vertical position ready for field installation. For horizontal installation, the blower module can be repositioned in the field as shown on pages 3 and 6 for maximum flexibility. ACCESSORIES INDOOR UNIT (FIELD INSTALLED) Supply Air Plenums and Return Air Grilles (expanded metal) accessories are available for free-standing indoor (15 Ton units only) units located in the conditioned space. Both accessories are finished to match the exterior of the basic unit, and both can be applied with either vertical or horizontal units. The supply air plenums are fully insulated and have double-deflection, adjustable grilles. Base Sections are available to raise vertical indoor units above the floor. Outdoor air may be introduced through these bases by cutting an access opening for the outdoor air duct connection. These bases are finished to match the exterior of the basic unit. They may have to be insulated in the field for certain applications. Suspension Kit is available for indoor units installed horizontally. Manual and electronic two stage thermostats are available for cooling applications. Both thermostats have a two-position fan switch, AUTO and ON to provide intermittent or continuous blower operation. Unitary Products Group 5
