REFRIGERANT PIPING CONNECTIONS
Indoor Unit Connections
Follow the steps below and refer to the illustrations on this page to connect piping to the Single Zone indoor unit. To see specific bundling of
piping and drain hose, see Section, “Bundling and Cutting Line” on page 36. Also, refer back to “Drain Hose Guidelines”
section for proper drainage slope during piping procedure.
1. From the rear of the indoor unit, carefully bend the copper pipe
tubing holder away from the unit to expose for conduit bracket
installation area.
Figure 36: Piping and Bundling - Indoor Unit
2. Position the bundled tubing by bending slowly downward first, as
shown in Figure 37.
• Bending the copper tubing directly left or right, without bending
downward first, may cause damage.
• Always secure the piping using the piping cover.
• Do not bend the pipes towards the front of the unit as this may dam-
age the unit.
