15 Chillled W ater Piping — See T ables 1C and 1D for chilled water connecton sizes. Fo r ease in bazing, it it recom- mended that all internal solder joints be made before unit is placed in final position. Knockouts are provided in the unit corner posts for 40RUS re- frigerant piping.
16 Condensate Drain — Install a trapped condensate drain line to unit connection as shown in Fig. 12. The unit drain con- nection is a PVC stub. See Fig. 13. Some areas may require an adapter to connect to either galvanized steel or copper pipe. For these applications, install a field-supplied threaded PVC adapter .
17 Power Supply and Wiring — Check the unit data plate to ensure that available power supply matches electrical characteristics of the unit. Provide a disconnect switch with an integrated lock-out feature of size required to provide adequate fan motor starting current.

21 Fig. 19 — Duct Flange Ins t a lla tio n ST AR T -UP Before starting unit, check the following and correct as necessary: • Is unit solidly supported? • Is fan adjusted for speed and pulley ali.
22 Centering Fan Wheel — If fan and fan shaft assembly are not properly centered, blades may scrape against the blower side scroll plate or may create an objectionable whistling noise. It may be necessary to adjust individual fan wheels or move en- tire fan shaft.
23 Fig. 23 — Fa n Rotation Fan Pulley Alignment — Align as follows: 1. Loosen setscrews on pulleys. 2. Align pulleys visually and tighten setscrews on fan pulley to lock it in place. 3. Use the methods shown in Fig. 24 to check proper pulley alignment.
24 Replacing Filters — Filters can be removed and in- stalled from either side of the unit. Install new filters in units that have one fan as follows: 1. Remove the side access panel (retain screws). 2. Remove the filter retainer clip (see Fig. 25).
