Site constraints
Confirm room layout, outdoor-unit location, drain route, service access, wall or window limits, and any building or lease rules.
Installation Guidance
Plan installation before the equipment arrives.
A useful installation plan covers placement, electrical capacity, condensate drainage, refrigerant handling, access, noise, permits, and final acceptance checks.
Acceptance evidence
Ask for commissioning notes, model numbers, warranty details, operating guidance, filter access, and signs that require service.
