Unit Positioning — The unit can be mounted on the floor for vertical application with return air entering the faceof the unit and supply air discharging vertically through thetop of the unit. The unit can also be applied in a horizontalarrangement with return air entering horizontally and the sup-pl...

Unit Isolation — Where extremely quiet operation is essential, install isolators between floor and base of unit, orbetween 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 whenleveling. Refrigerant and ...

IMPORTANT: Never attach the sensor to the suctionmanifold. 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 off 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 drainconnection is a PVC stub. See Fig. 11. Some areas may re-quire an adapter to connect to either galvanized steel orcopper pipe. For these applications, install a field-suppliedthreaded PVC...

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 ofsize required to provide adequate fan motor starting current.See Tables 4 - 6 for unit electrical data. Install disconnect switch a...
