SPECIAL DESIGN REQUESTS
Units are sometimes built units with special features as
requested by the customer. This manual only covers standard
features and does not include any changes made for special
feature requests by the customer. Units built with special
features are noted with a 5-digit SPO (Special Product Order)
Number on the Serial Plate.
UNIT LOCATION
DANGER
Appliances must not be installed where they may be exposed
to potentially explosive or flammable atmosphere.
HANDLING
Each unit will be shipped to the site secured to a wood skid
using metal brackets. Whenever possible, all lifting and handling
of the unit should be done with the packing and skid in position.
Due to the length of the unit, 72" forklift tines are recommended
to avoid damaging the unit.
Remove the metal brackets prior to lifting the unit off of the skid.
When slinging or using a forklift to lift the unit, the support points
should be sufficiently apart to give stability when lifting. Unless
otherwise noted the lifting points should be equidistant from the
centerline. Extreme care should be taken not to drop the unit.
Considerable damage can occur to the unit during positioning,
in particular, to the paneling and exterior paint. Use an adequate
number of personnel and the correct tools when moving the unit.
A lifting device such as a forklift is needed to install this product.
A special key is provided with the unit for use with the tamper-
proof cabinet locks on the top and front panels. The use of
torque screwdrivers on panel, cover or component mounting
screws is not recommended. Hand-start all screws. If electric
drills are used – set at the lowest possible torque.
PREPARATION
1. Select the unit location. Ensure the wall or ceiling structure
is adequate for the required mounting provisions as
outlined in the "INSTALLATION" section. For Ceiling
Mounted units (Model Digit 2=C), check that ceiling is
capable of supporting the weight of the unit.
2. Before installation, ensure that the correct electrical power
supplies are available for the unit.
3. Each unit requires an independently fused and isolated
power supply.
4. If the installation has multiple units, check that unit model
and tagging corresponds with the installation plans.
Please contact your Airedale representative immediately if
discrepancies are noted.

Drainage
Units with cooling coils have a condensate drain pan connection
and 3/4" ID condensate line. The condensate drain pan
connection is field changeable and can be mounted on either
the left or right side of the unit. To change the connection
location, remove the condensate line from the elbow. Remove
the elbow from the drain pan and remove the plug from the
opposite side of the drain pan. Re-install the elbow and the
plug on the opposite sides of the drain pan. Re-connect the
condensate line.
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 4.1). 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" diameter fasteners with 1-1/2"
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.
