for application with the intended outdoor unit. Depending
on application, additional installer supplied orifice or
TXV may be required.

adequate to handle the static pressure drop of the coil,
filter, and duct work.
• If precise forming of refrigerant lines is required, a
copper tubing bender is recommended. Avoid sharp
bends and contact of the refrigerant lines with metal
surfaces.

sensitive neoprene or other suitable material where
they pass against sharply edged sheet metal.
• Horizontal installations require a horizontal drain pan
kit to be installed. See Table 1 (page 3) for part number.
