Unit Positioning — The unit can be mounted on the floor for vertical application with return air entering the face of the unit and supply air discharging vertically through the top of the unit. The unit can also be applied in a horizontal arrangement with return air entering horizontally and the sup- ply air discharging horizontally .
Unit Isolation — Where extremely quiet operation is essential, install isolators between floor and base of unit, or between ceiling and top section of unit. Be sure that unit is level and adequately supported. Use channels at front and sides of unit for reference points when leveling.
IMPOR T ANT : Never attach the sensor to the suction manifold. Do NOT mount the sensor on a trapped por - tion of the suction line. 40RM Series evaporator coils have a face-split design. En- sure that lower circuit of coil is first on/last of f when con- nected to the condensing unit and/or system controls.

Condensate Drain — Install a trapped condensate drain line to unit connection as shown in Fig. 10. The unit drain connection is a PVC stub. See Fig. 1 1. Some areas may re- quire an adapter to connect to either galvanized steel or copper pipe. For these applications, install a field-supplied threaded PVC adapter .
Power Supply and Wiring — Check the unit data plate to ensure that available power supply matches electri- cal characteristics of the unit. Provide a disconnect switch of size required to provide adequate fan motor starting current. See T able s4-6f o r unit electrical data.

ST ART -UP Before starting unit, check the following and correct as necessary: • Is unit solidly supported? • Is fan adjusted for speed and pulley alignment? • Are pulleys, motor , and bearings .
Centering Fan Wheel — If fan and fan shaft assem- bly are not properly centered, blades may scrape against scroll or may create an objectionable whistling noise. It may be necessary to adjust individual fan wheels or move entire fan shaft. See the following two sections.
Fan Pulley Alignment — Align as follows: 1. Loosen setscrews on pulleys. 2. Align pulleys visually and tighten setscrews on fan pul- ley to lock it in place.
