Piping

Units with Hydronic Coil Connections Only

Piping Considerations

Before installing field piping to the coil, consider the following .

·All coil connections are 5/8 inch O.D. (or 1/2 inch nominal) female copper connections.

·The supply and return piping should not interfere with the auxiliary drain pan or condensate line. See “Connecting the Condensate Drain” section on page 25 for more detailed information.

·The installer must provide adequate piping system filtration and water treatment.

·Condensate may be an issue (fan-coils only) if field piping does not have a control valve.

Refer to Figure 6 for supply and return header locations.

!CAUTION: When using a field supplied piping package in a fan-coil unit, allow sufficient room to install the auxiliary drain pan. In addition, piping package must not extend over edges of auxiliary drain pan.

Connecting field piping to coil:

1.Slide a 1/2 inch sweat connection coupling (installer provided) onto the coil headers.

2.Remove the auxiliary drain pan, if it is in place, to prevent exposure to dripping solder or excessive temperatures.
