GENERAL
The 265v Electrical Subbase Accessory nmst be used whenever the
packaged ternfinal air conditioner or heat pump is installed in a
wall less than 2 in. (50.8 ram) thick, or where wall sleeve extends 4
in. (101.6 ram) or more into room, or for additional support or
leveling of air conditioner or heat pump. Wall sleeve must be 3-1/4
in. (82.6 ram) minimum into room and 3-1/4 in. (82.6 ram)
nfininmm to 5-1/2 in. (139.7 ram) naaxinmm above floor.
The electrical subbase has a factory-installed electrical junction
box containing a receptacle for corded packaged ternfinal air
conditioner (PTAC) units, Knockouts are provided for power
source connections,
INSTALLATION
IMPORTANT: Refer to chassis nameplate for power source
requirements.
Building power source wiring can enter subbase through any
conduit knockout hole in bottom of subbase or through the
knockouts in the electrical junction box walls.
All wiring must comply with local electrical codes and National
Electrical Code (NEC).
NOTE: The factory-installed receptacle must match the chassis
plug. Refer to PTAC Owner's Manual to choose the correct
subbase.
Step 1 --Disconnect all power to unit and remove front panel.
Step 2 --Prepare wall sleeve. Drill one 1/8 in. (3.18 ram) hole on
each side of wall sleeve. If installing plastic sleeve, use locator
dimple on outside of sleeve. Drilling can be done through the
plastic from inside if desired. See Fig. 1.

NOTE: If installing metal sleeve, mark location of holes on sleeve
then drill 1/8-in.(3.2 ram) holes. See Fig. 2 for hole dimensions
on metal sleeve.
Step 3 --(Optional) Adjustable Side Extension Panels can be
attached to cover open space left between subbase and wall.
Determine the distance from inside wall to front of wall sleeve.
See Fig. 3, dimension X.
Step 4 --Attach Side Extension Panels to subbase using one black
screw on each side so that panel end extends dimension X plus 2
in. (50.8 ram) from front of subbase. To adjust side panel, simply
bend panel at slot position. See Fig. 1 and 3.
NOTE: Use engagement holes for more exact fit to wall. See Fig.
1.
Step 5 --Bring power into the subbase electrical junction box
using one of the knockouts for conduit connections. See Fig. 4.
Step 6 --Take larger, left access cover off and use field supplied
wire nuts to connect power to receptacle wires. Replace cover. See
Fig. 4 and 5.
Step 7 --Attach subbase to wall sleeve. Subbase has side tabs for
mounting the subbase to the sleeve. Be sure hole on side tab is
lined up with pre-drilled locator hole on side of sleeve. Once
holes are aligned, attach subbase to sleeve with one (1) black screw
on each side. Do not over tighten. See Fig. 1 and 4.
Step 8 --Level subbase flush with floor by adjusting leveling bolts
beneath each end of subbase.
