APEX Installation Checklist

Wall Openings

• Two 6" x 12" wall openings are installed on opposite sides of the cellar to generate effective cross-flow:
• Supply Air: High on the wall
• Return Air: Low on the wall

Mechanical Room Access

• Adequate space nearby to house the cooling unit
• Ventilation in the room is sufficient to dissipate heat

Ductwork Requirements

• Ducts (e.g., 8" supply and 8" return) are planned with:
• Maximum of 25 feet per duct (50 feet total combined)
• Smooth, gradual bends (avoid sharp turns)
• Ducts will be insulated to prevent condensation and minimize noise

Dedicated Electrical Circuit

• A dedicated circuit is available for the unit:
• Typically 115V/20A (or 120V/15A, based on your specific unit requirements)
• No GFCI outlet is used

Drain Access

• A drain is located within 15 inches of the unit, or a condensate pump is planned if farther away
• Ensure proper drain line installation with a slight slope and no blockages

Insulation Standards

• Walls: Minimum R20 insulation
• Ceiling: R20–R30 insulation
• Floor: Minimum R20 insulation (if the cellar isn't in a basement)

Vapor Barrier

• A vapor barrier is installed on the warm side of the walls/ceiling

Floor & Door Considerations

• There are no heated floors, or a 12-inch gap is maintained if present
• The cellar door has proper seals; note that glass doors may need additional insulation

Mechanical Room Temperature

• The room housing the unit maintains an ambient temperature between 50°F and 77°F (10°C to 25°C)

Humidity Control

• The cellar area is not prone to high humidity, reducing the risk of mold and system strain

Unit Handling

• The cooling unit must be kept in an upright position, with the compressor at the bottom, for at least 24 hours before installation
