*Requires a double suction riser if 2 unloaders are used and the evaporator is below the condensing unit. See Table 4B and Fig. 4 for more information.

NOTES:

1.Pipe sizes are based on a 2 F (1.1 C) loss for liquid lines and a 1.5 F (0.8 C) loss for suction lines.

2.Pipe sizes are based on an equivalent length equal to the maxi- mum length of interconnecting piping plus 50% for ®ttings. A more accurate estimate may result in smaller sizes.

*Requires a double suction riser if 2 unloaders are used and the evapo- rator is below the condensing unit. See Table 5B and Fig. 4 for more information.

NOTES:

1.Pipe sizes are based on 2 F (1.1 C) max loss for liquid lines and 1.5 F (0.8 C) max loss for suction lines, selected at maximum length for each interval and for matched systems at nominal rating con- ditions, nominal air¯ow.

2.Pipe sizes are based on an equivalent length equal to the maxi- mum length of interconnecting piping plus 50% for ®ttings. A more accurate estimate may result in smaller sizes.
