Preparing for Installation
Before you touch a single wire or duct, proper preparation is essential. Here’s how to set the stage for a smooth installation:
1. Selecting the Right Location
-
Level Surface: Make sure the AC sits on a firm, level base. Uneven placement can cause vibrations, reduce efficiency, and shorten the system’s lifespan.
-
Clearances: Ensure there’s enough clearance around the unit for airflow and maintenance access. Typically, 12–24 inches on the sides and at least 5 feet above is recommended.
-
Shade vs. Sun: If possible, place the unit in a shaded area to reduce heat load and improve efficiency.
2. Electrical Preparation
-
Power Requirements: This model runs on 208/230V single-phase power, so confirm your electrical panel matches.
-
Breaker & Wiring: Use the correct wire gauge and breaker size according to the manufacturer’s specifications to avoid overheating or fire hazards.
-
Grounding: Proper grounding is critical for safety and to prevent electrical surges from damaging the system.
The National Electrical Manufacturers Association (NEMA) provides helpful guidelines for proper wiring and breaker setup.
3. Ductwork & Airflow Planning
Proper ductwork ensures your AC can move cooled air efficiently throughout your space.
-
Sizing: Ducts that are too small restrict airflow; ducts that are too large reduce efficiency.
-
Sealing: Use mastic or foil tape to seal all duct joints. Leaks can account for up to 30% of your cooling losses.
-
Registers & Vents: Position supply vents strategically for balanced airflow. Avoid placing them behind large furniture.
