Page 12: Unit Positioning
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 supply air discharging horizontally.
Page 13: Unit Isolation
Do NOT mount the sensor on a trapped portion of the suction line. The 40RU Series evaporator coils have a face- - split design. Ensure that lower circuit of coil is first on/last off when connected to the condensing unit and/or system controls. See Fig.

Page 17: Chilled Water Piping
Supply Upper To size, design, and install chilled water piping, consult the Carrier System Design manual. See Fig. 12 for an example of a typical installation. Recommended fittings are listed in Table 3. To access 40RUS coil vents and drains, remove the unit side panel over the coil header.
Page 18: Condensate Drain
Condensate Drain — Install a trapped condensate drain line to unit connection as shown in Fig. 13. The unit drain connection is a PVC stub. See Fig. 14. Some areas may require an adapter to connect to either galvanized steel or copper pipe.

Installation with Accessory Electric Heaters Size the Field Power Wiring between the heater TB1 and the 40RU indoor fan motor per NEC Article 430--- 28 (1) or (2) (depends on length of conduit between heater enclosure and 40RU power entry location). Install wires in field --- installed conduit.
Page 22: Connecting Ductwork
Connecting Ductwork - - Refer to the Carrier System Design Manual for the recommended design and layout of ductwork. Fig. 19 shows recommended duct connection to units with 2 fans. CAUTION UNIT OPERATION HAZARD Failure to follow this caution could cause equipment damage.
Page 23: Start- - Up
START- -UP Before starting unit, check the following and correct as necessary: S Is unit solidly supported? S Is fan adjusted for speed and pulley alignment? S Are pulleys, motor, and bearings securely mounted? S Are there any loose parts that will rattle or vibrate? S Is condensate drain pan pitched for correct drainage? S Are coil baffle plates tight against coil to prevent air bypass?
Page 24: Fan Shaft Bearings
Fan Shaft Bearings - - Bearings on size 07- - 12 units are sealed, permanently lubricated bearings that require no further lubrication. Size 14- - 16 units have pillow- - block bearings (Fig. 23) that must be lubricated with suitable bearing grease approximately every 3 months.
Page 25: Individual Fan Wheel Adjustment
Individual Fan Wheel Adjustment - - Loosen the 2 locking bolts holding fan wheel hub to shaft. See Fig. 23. Position fan wheel in center of the fan housing and tighten locking bolts. Clearance between wheel and housing should be the same on both sides. Fan Belts - - Motor mounting plate and motor support angles are slotted to permit both vertical and horizontal adjustment.
Page 26: Chilled Water Coil Freeze Protection
Chilled Water Coil Freeze Protection - - Shut off water supply to unit. Remove side panel of unit and remove vent and drain plugs in top and bottom of coil header. Drain coil and blow out remaining water. Reinstall plugs and side panel.
