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. Check that ceiling is capable of
supporting the weight of the unit.
2. Check to make sure that the units will have adequate
installation clearance around them.
3. The cabinet must be suspended using the four mounting
holes located on the top of the unit from ceiling joists or
other suitable supports. Do not suspend the unit at any other
locations. The unit is to be installed level front to back and
side to side.
4. Before installation, ensure that the correct electrical power
supplies are available for the unit.
5. Each unit requires an independently fused and isolated power
supply.
6. 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.
7. Note that units with cooling coils will have a condensate
connection and suitable provisions should be made for
draining. If multiple units tee into a common drain manifold,
it must be sized to ensure free draining with all the units in
operation.

8. For units with outside air, inspect the wall sleeve and louver
installation for gaps that would allow leakage of outdoor air
into the space. All joints and abutments should be sealed with
waterproof sealant.

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.
The condensate line must be connected to the main drain
system in accordance with any local codes and general good
piping practice. For units equipped with an optional condensate
pump, the maximum lift is 15 feet.

Electrical

Electrical wiring should be done in accordance with all
applicable national and local codes. It is the responsibility of the
electrical contractor to adhere to such codes. The warranty will
be voided if wiring is not in accordance with the specifications of
the unit. Use copper conductors only.
All power supply wiring must be capable of carrying the
maximum current load under no fault conditions at the stipulated
voltages. Care should be taken to avoid significant voltage
drops.
A knockout with strain relief is provided on the electrical box for
power wiring. Each unit is supplied with terminal strip for power
connection.

INSTALLATION

The instructions detailed below are for the Installation of a
"standard" unit. Accommodations and adjustments will be
required for the usage of additional unit options/accessories.
Should assistance be required for the installation of these
additional items, consult Modine at the phone number listed on
the back cover of this manual.
1. Airedale recommends rear of unit be positioned at least 2"
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" diameter washers to suspend
the unit at the mounting holes located at the top of the unit
(see Figure 4.1). The unit must be suspended at each of the
(4) 1 inch mounting holes. Do not suspend from any other
locations.
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.
