NOTES:
1. Do
NOT exceed the limits in the liquid and suction line sizing charts.
2. Do NOT use 7/8 OD suction lines in 2 or 3-ton applications.
3. 1-1/8 OD suction line approved for 5-ton applications only but has length
restrictions. Reference the liquid and suction line sizing charts.
*Standard Line Size
7.0 INTERCONNECTING TUBING
7.1 Vapor and Liquid Lines
Keep all lines sealed until connection is made.
Make connections at the indoor coil first.
Refer to Line Size Information in Tables 3, 4, 5 and 6 for correct size and multipliers
to be used to determine capacity for various vapor line diameters and lengths of run.
The losses due to the lines being exposed to outdoor conditions are not included.
The factory refrigeration charge in the outdoor unit is sufficient for 15 feet of inter-
connecting lines. The factory refrigeration charge in the outdoor unit is sufficient for
the unit and 15 feet of standard size interconnecting liquid and vapor lines. For dif-
ferent lengths, adjust the charge as indicated below.
1/4” ± .3 oz. per foot
5/16” ± .4 oz. per foot
3/8” ± .6 oz. per foot
1/2” ± 1.2 oz. per foot
7.2 Maximum Length of Lines
The maximum length of interconnecting line is 150 feet. Always use the shortest
length possible with a minimum number of bends. Additional compressor oil is not
required for any length up to 150 feet.
NOTE: Excessively long refrigerant lines cause loss of equipment capacity.

CAUTION
When coil is installed over a finished ceiling and/or living area, it is
recommended that a secondary sheet metal condensate pan be
constructed and installed under entire unit. Failure to do so can result
in property damage.
