STEP 7: WIRING THE UNIT
The low voltage transformer in the unit has a 208 volt tap
in the primary winding (color coded RED). If unit is to be
operated with 208 volt electrical service, remove the 230
volt ORANGE lead from the L2 terminal and connect the
208 volt RED lead to the L2 terminal. Be sure to insulate
the end of the unused ORANGE lead.
Locate the room thermostat on a wall near the return air
box, between 40" to 48" from the floor. Connect the low-
voltage thermostat wiring from the room thermostat to the
low voltage control block in the unit.
Connect low voltage from fan coil unit to condensing unit
as shown in Figure 2.9.
