pump is installed in a wall less than 2 in. thick, or where wall 
sleeve extends  4 in. or more into room, or for additional 
support or leveling of air conditioner or heat  pump. Wall

NOTE: If electrical connections are required, either an electri-
cal subbase or electrical accessory kit can be ordered from the 
factory. 
INSTALLATION 
To  properly  install  the  subbase,  follow  these  simple 
instructions: 
Step 1 — 
Prepare wall sleeve. Drill one

 in. hole on each 
side of wall sleeve. If installing plastic sleeve, use locator dim-
ple on outside of sleeve, found near bottom, front section. 
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

-in. holes. See Fig. 2 for locator hole dimen-
sions on metal sleeve. 
Step 2 (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 3 — 
Attach Side Extension Panels to subbase using 
1 black screw on each side so that panel end extends dimension 
X plus 2 in. from front of subbase. To adjust side panel, simply 
bend panel at slot position. See Fig. 1. 
Step 4 — 
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 locator hole on side of sleeve. Once 
holes are aligned, attach subbase to sleeve with (1) one black 
screw on each side. Do not overtighten. See Fig. 1 and 3. 
Step 5 — 
Level subbase flush with floor by adjusting level-
ing bolts beneath each end of subbase. See Fig. 4 for completed 
subbase assembly.
