7) Chassis Final Connections
With the chassis in place, you are now ready to begin chassis connections:
A.Move the thermostat switches to "OFF" and "AUTO." This will keep the thermostat from cycling the chassis until final connections are complete.
B.Connect the ductwork onto the 10" collar. Plastic wireties (field supplied) are suggested to secure the ductwork in place. Use 2 wire ties, one for each inner and outer flex duct sleeve.
C.Using the two 3/4" plugs supplied with the unit, plug two of the condensate drain holes. Connect a drain to the third condensate exit location. Be sure to use teflon tape or approved pipe sealant on all drain connections and plugs. (See Figure 10.)
D.For 208 Volt power only: you must move the transformer wire as shown in Figure 7, Page 9.
E.Review the Final Installation Checklist on Page 12 before replacing the power quick disconnect, reconnecting power to the chassis, plugging in the remote thermostat harness, or operating the chassis.

Electrical shock and moving parts hazard can cause injury or death. If you have not done so, pull out the disconnect head found on the front of chassis before continuing instal- lation! Disconnect external power at the breaker.

8) Final Installation Checklist
Correct line voltage?
Chassis deck level?
Plenum divider baffle installed?
Wall plenum caulked? Level? Flashing?
HACR type breaker/fuse?
CAUTION
17 x 21/8
Single circuit only?
The unit basepan has three (3) provisions (left, right, and rear) for connecting an external condensate drain.
A field supplied condensate drain system must be connected to one of the three (left, right, or rear) 3/4" FPT connections on the unit basepan. Use of rear fitting may result in staining of the outside wall.
The remaining two connections must be plugged using the two 3/4" pipe plugs (provided) and field supplied teflon tape or pipe joint compound.
The addition of a secondary drain pan may be required. Follow all applicable codes.
Failure to follow these procedures may result in serious property damage.
A field supplied secondary condensate pan may be applied. Check with local codes.
Ductwork connected?
Chassis weather seal in place?
Wall thermostat wired correctly?
Chassis inserted into plenum?
