INSTALLATION

INSTALLATION - FLOOR MOUNTED
(MODEL DIGIT 2=F) UNITS
Note:


(Ceiling Mounted Units proceed to the next section.)
The instructions detailed below are for the Installation of a
"Standard" unit. Accommodations and adjustments will be
required for the usage of additional unit accessories. Should
assistance be required for the installation of these additional
items, contact the factory at the phone number listed on the
back cover of this manual.
1. Check the walls and floor for straightness and check to
ensure that the wall is at a right angle to the floor. Should
there be any irregularity, the placement of foam tape on the
outside edges of the unit will fill the gaps between the unit
and the wall, allowing for the use of a sealant, to create a
smooth transition from the unit to the wall.
2. Remove the backing strip from the gasket on the wall
sleeve. Place the unit in the correct location, ensuring a
tight seal with the wall sleeve and the wall.
3. Place the unit in position and use the leveling legs to
ensure that the unit is level in both directions and also
plumb. Remove the front kick panel to access the leveling
legs (see Figure 6.1). Make sure that the foam gasket on
the back of the unit forms a tight seal between the unit and
the wall.
4. After adjusting for any irregularity in the location site, the
cabinet must be secured to the back wall. The back of
the cabinet has four holes, two on each side. The type
of materials used for the walls will determine the type of
fastener to use. Use 3/8" (9.5mm) diameter fasteners with
1-1/2" (38.1mm) diameter washers. Securing the cabinet
to the wall helps to reduce movement and noise due to
vibration. Drill the appropriate sized holes for the fasteners
that are to be utilized, and insert the anchors that are to be
used.
5. Make the condensate drain connection and the electrical
connections to the unit. For standard units the condensate
connection will be located in the left end compartment
when left hand cooling is selected, and in the right end
compartment when right hand cooling is selected. For units
with a cooling piping package, condensate drain connection
will always be located in the right end compartment.

INSTALLATION - CEILING MOUNTED
(MODEL DIGIT 2=C) UNITS
The instructions detailed below are for the Installation of a
"Standard" unit. Accommodations and adjustments will be
required for the usage of additional unit accessories. Should
assistance be required for the installation of these additional
items, contact the factory at the phone number listed on the
back cover of this manual.
1. It is recommended that the rear of unit be positioned at
least 2" (50.8mm) away from a wall or structure to ensure
bottom access panel containing filter and electrical box can
fully open.
2. Remove both end panels to allow for access to the
mounting holes. If installation does not allow for access
through the end of the unit, remove bottom panels prior to
placing unit on lifting device.
3. Place protective material on the supports of the lifting
device to prevent scratching or denting of the unit. Place
unit on the lifting device supporting the unit across its entire
length.
4. Raise the unit to the mounting position. Use field supplied
rods and fasteners with 1-1/2" (38.1mm) diameter washers
to suspend the unit at the mounting holes located at the top
of the unit (see Figure 6.2). The unit must be suspended
at each of the (4) 1" (25.4mm) mounting holes. Do not
suspend from any other locations. It is the responsibility of
the installer to provide mounting hardware in accordance
with local codes and sized appropriately for the given load.
5. Install unit level and plumb to prevent excessive vibration
and premature failure. To ensure proper drainage unit
must be level. Do not mount unit on a slope. Tighten all
fasteners.
6. Make the condensate drain connection to the unit.
