All coils have same end supply and return connections.2. Steam coils have a factory installed pressure equalizing valve and a 24ʺ(610mm) long pressure equalizing line which terminates in a 1⁄2ʺ M.P.T. fitting.3. Steam/hot water connections may be same end as cooling coil connections,but they are recommended to be opposite end to facilitate piping. (Must beopposite end when using Daikin controls.)4. Cooling condensate drain pan is shipped sloped down towards the coolingcoil connections but is field reversible.5. Electric heating coil power connections are right end only. Junction box has1ʺ(25mm) and 2ʺ (51mm) (trade size) knockouts, 10-1⁄2ʺ (267mm) from rightend of the unit.6. Coil stubs are 7⁄8ʺ I.D. (female) and terminate 9ʺ (229mm) from the end ofthe unit.7. Steam coils are 1-1⁄8ʺ female (sweat) connections and terminate 9ʺ (229mm)from the end of the unit.8. DX coils (G) have O.D. sweat connections. Interconnecting tube by others.See Table 5 for correct tubing size.Table 4: Coil Connection Dimensions For Lettered ValuesUnit Depth DimensionsA B C D Jin 16-5/8 3-3/4 12-1/4 4-7/8 7-3/4 3mm 422 95 311 124 198 76in 21-7/8 9 17-1/2 10-1/8 13 8-1/4mm 556 229 445 257 330 210Table 5: DX Coil (G) Connection TubingUnit Series S07 S10 S13 S15in mm in mm in mm in mmSuction Line OD: 3/4 19 3/4 19 7/8 22 7/8 22Liquid LIne OD: 1/4 6.35 1/4 6 3/8 10 3/8 10
