Piping Preparation
• Do not open service valves or remove protective caps from tubing ends until all
connections are made.
• Keep tubing free of dirt, sand, moisture and contaminants.
• Use a flexible condensate drain hose to fit over the factory 5/8-inch (15mm) drainage hose.
• Insulate each refrigerant pipe and condensate hose with minimum 3/8” (10 mm) wall
thermal pipe insulation.
NOTE: Insulate the interior portion of the condensate hose to prevent sweating which
may cause water stains or wall damage.
• Bind refrigerant pipes, condensate hose and interconnecting wire together with cable
ties at 12 inch intervals on the exterior portion.
