section on page 3 for details.
†Outdoor unit is shipped with a holding charge. Refer to unit name-
plate (on unit) for details on specific system charge required.
**When matched with 030 outdoor unit/when matched with 036 out-
door unit.
††The valve connection size is

pump is used.
3. Remove inlet grilles from indoor unit by sliding forward.
Reinstall prior to unit start-up.
4. If necessary, reconfigure the 24,000 Btuh fan coil unit to
18,000 Btuh as follows:
a. The plug to the motor is located just outside the con-
trol box. Refer to the label diagram on the plug for
wiring for both 18,000 Btuh and 24,000 Btuh units.
b. Remove the black, blue, yellow, and red wires from
the plug. The white wire is the common and remains
in the same position.
c. Insert the blue wire into pin number 1.
d. Insert the yellow wire into pin number 2.
e. Insert the red wire into pin number 3.
f. Insert the black wire into pin number 4.
g. Check all connections to ensure they are secure.
h. Reinstall grilles using the screws removed in Step b.
i. Reinsert filters removed in Step a.
Step 2 — Select Location —
Consult local building
codes and NEC for special installation requirements. See
Fig. 3 and 4 for unit dimensions and required clearances.
There are several ways the unit may be installed to dif-
ferent types of ceiling construction. These instructions do
not cover all installation methods. As a typical installation,
these instructions focus primarily on mounting the unit to
metal in new construction. Plan your installation carefully
before you begin. Listed below are some guidelines that should
be followed when determining location for the unit.
1. Place unit adjacent to an outside wall if fresh air is
required, ensuring that location allows for complete air
distribution.
