combinations, and Table 2 for application range. Refer to

this manual for proper installation of the complete system. Refer to Table 1 to make sure the correct indoor unit is in-

stalled with the correct outdoor unit. Be sure the unit will be

operated within the application guidelines shown in Table 2. When installing the 38AN or 38BK unit, it is important to note that for cooling operation when the outdoor air tem- perature is below 55 F, it is necessary to equip the outdoor unit with the low-ambient accessory.

To install this unit you will need:

140QNB or 40QNE/H Fan Coil unit with standard wire- less remote controller and indoor unit wire

1-- 38AN or 38BK Outdoor Unit

1 -- Low-Ambient Kit (if required for your application)

NOTE: Field-supplied wire, drain pipe, refrigerant tubing, etc., are also required to install unit.

The installation materials provided are for use on instal- lations where the indoor section is mounted to gypsum wall board with wall studs. Other types of applications require field-supplied mounting hardware. Be sure to follow all in- stanation instructions in this manual carefully in order to achieve proper unit operation, and be sure that you have all of the required parts before beginning installation.

Note that the cooling only and heat pump systems utilize

a microprocessor control system to deliver optimum levels of comfort and efficiency. Refer to Microprocessor Control Operation section on page 15 for details.

INSTALLATION

Step 1 --Complete Pre-lnstallation Checks

UNPACK UNIT(S) Store unit(s) in original packaging until moved to the final site for installation. When removing unit from carton, lift by its 4 comers. Note that there is a plastic bag containing mounting screws taped to the mount- ing bracket.

INSPECT SHIPMENT -- Upon receipt of shipment, in- spect unit (Fig. 1) for damage. Forward claim papers di- rectly to the transportation company. Manufacturer is not re- sponsible for damage incurred in transit.

Check all items (see Table 3), and if any item is missing, notify your Carrier distributor. To prevent loss or damage, leave all parts in the original packages until installation.

NOTE: The expansion device is located in outdoor unit.

Step 2 --Select Location --Consult local building codes and NEC for special installation requirements.

NOTE: There are several ways the unit may be installed in different types of wall construction. These instractions do not cover all installation methods. As a typical installation, these instructions focus primarily on mounting the unit to wall studs in new construction.

Plan your installation carefully before you begin. Listed

below are some guidelines to follow when determining a lo- cation for the unit:

1.Center unit (horizontally) on the wall selected.

2.Allow sufficient space for airflow clearance, wrong, re- frigerant piping, and servicing the unit. See Fig. 2-4.

3.Place the unit so it faces normal location of room occupants.
