INSTALLATION OF REFRIGERANT PIPING
Step 6
Piping Connections
Use refrigeration grade tubing ONLY. No other type of tubing may be used. Use
of other types of tubing will void manufacturer’s warranty. Make sure there is
enough piping to cover the required length between the outdoor and indoor unit.
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 (16mm) drainage hose.
• Insulate each refrigerant pipe and condensate hose with minimum 3/8” (10 mm) wall
thermal pipe insulation.
NOTE: Insulate 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.
NOTE: A condensate pump accessory (sold separately) is recommended for the
indoor unit when adequate line pitch cannot be provided for drainage.
