Fig. 2—Wind Baffle Construction for Cube Units

Calculate the linear length of vapor tube required, adding any losses for the total number of elbows for application. (See Table 5.) Using this equivalent length, select desired vapor-line size from Table 4. Subtract the nominal percentage loss from outdoor-unit presale-literature Detailed Cooling Capacities data for the given indoor/outdoor combination. Reference all notes of Table 4.

NOTE: When specifying vapor-line insulation, be aware of the following standard practice:

All standard accessory-tubing kits are supplied with 3/8-in. insu- lation on vapor line.

For minimal capacity loss in long-line application, 1/2-in. insula- tion should be specified.
