Excessive Weight Hazard
Use two or more people when
installing your air conditioner.
Failure to do so can result in
back or other injury.
STEP 1. Check the sleeve to be certain it has been correctly installed
in the wall. Remove the front panel on the USC SLEEVE. Remove the
rear WEATHER PANEL. Reverse grille. Place lower edge into sleeve
tab (Friedrich logo facing out). Align slots with the screw holes.
Secure grille with screws.
A. Check the anchor screw. There should be four (4) in the USC
SLEEVE (two in each side).
B. Determine if the sleeve has a downward slope of 3/8 to the
outside. See figure C.4.2 for further details.
C. Check to be sure the sleeve has been sealed around all edges
with an industrial type caulking on both the outside and inside to
prevent rain entry.
STEP 3. Check the electrical receptacle to see that it conforms to
the requirements for the chassis model to be installed. See Figure
E.1 for the receptacle requirements.
STEP 4. Remove the chassis from the shipping carton. Lift the
chassis by the basepan and slide it into the front of the sleeve.
(Obtain assistance as needed.) Push the chassis all the way into the
sleeve, using the plastic front handles, so that the front panel meets
the front edge of the shell.
NOTE: Chassis comes with pre-installed seal gasket.
Figure C.5.1
IMPORTANT: To ensure proper performance and energy efficiency it is essential that the chassis is properly installed in the wall sleeve.
This includes:
1. Utilize the proper rear grille.
2. Sealing all gaps between the unit and the rear grille.
3. Sealing all gaps around the units to prevent air leakage from outside of the building to the inside.
4. Installing the chassis so the rear grill is flush or extends beyonfd the sleeve.
CAUTION
Cut/Sever
Although great care has been
taken to minimize sharp edges
in the construction of your unit,
use gloves or other hand
protection when handling unit
Failure to do so can result in minor
to moderate personal injury.
