defects in material and workmanship.
This is a vertical, wallmount unit designed for many different
applications in both residential and commercial settings. It is selfcontained and arrives completely assembled, factory-charged and
wired. The unit is 100% run-tested at the factory to ensure proper
operation. Your unit is supplied with high-quality copper tubing and
enhanced aluminum-finned coils for high heat transfer efficiency
and long life. The unit cabinet is constructed of G-90 galvanized
steel. All exterior surfaces are finished with a baked-on polyester
coating. This will provide excellent corrosion protection in most
applications. However, if the unit is installed in an area with a
corrosive atmosphere, such as near an industrial plant or on the
seacoast, additional coating should be considered to extend the
life of the coils and cabinet.
This unit was designed for up to 105ºF of ambient temp
erature.
INSPECTION AND UNPACKING
A thorough inspection of the shipping container should be made
immediately upon receiving your unit. Look for any punctures or
openings. If it appears as if damage has occurred, it should be
noted on the freight bill before signing. The delivering carrier
should be contacted immediately to inspect damage, and no
installation work should begin until this inspection is completed.
OPERATING INSTRUCTIONS
If heating and cooling functions are controlled by separate
thermostats,
during the cooling season to prevent simultaneous operation of the
heating and cooling systems. Reverse the procedure during the
heating season.
If the same thermostat controls both heating and cooling
functions, set the thermostat to either HEAT or COOL as desired.
Set the desired temperature on your thermostat and set the fan
switch
(for air circulation only when the air conditioning system is
operating).
IMPORTANT: Wait at least three (3) minutes after turning the air
conditioner off before trying to restart. If an attempt is made to start
the compressor before the refrigerant pressures are equalized, the
compressor motor may trip on its overload. An additional waiting
period will be required before restarting.

weather elements. Treat it with a good automobile paste wax
twice a year (in the spring and fall).
Check with your contractor if you have any questions regarding
the maintenance or operation of your unit.
INSTALLATION
. CODES
A
The installer SHALL comply with all local, state, and federal codes
and/or regulations pertaining to this type of equipment and its
installation. Such codes and/or regulations should take
precedence over any recommendations contained herein.
Installations SHALL be made in accordance with the National
Electrical Code, local codes, and recommendations made by the
National Board of Fire Underwriters.
B. UNIT SITE SELECTION
1. To eliminate noise from being transmitted into noise
sensitive areas, the unit should NOT be installed on walls
adjoining bedrooms, sleeping quarters, or adjacent to
windows.

obstructions for unrestricted airflow.
from any obstructions to prevent recirculation of condenser
air.
Bottom of the unit SHALL be located at least 12" away from
6.
the ground or other obstructions for unrestricted airflow.
5. R
eturn and supply grilles must be used when the return
and supply are not ducted. When a supply grille is used
in the installation, the louver spacing must be no greater
than 5/8 inch.
6. If the factory-installed filter is used on your installation,
access to the filter is made through the center panel on the
front of the unit.
IF A REMOTE FILTER IS USED, SUCH AS A FILTER GRILLE,
THE FACTORY-INSTALLED FILTER MUST BE REMOVED AND
DISCARDED.
D. DUCTWORK
1. Properly-sized duct systems are critical for satisfactory
operation of any air conditioning system. All ductwork
MUST be correctly sized for the design air flow requirement
of the equipment.
2. The recommended operation duct static is to deduct 0.07"
W.C. for any size of heater 5 kW to 20 kW on factory or
field-installed heaters.
3. Ductwork routed through wall cavities, as well as any duct
not in conditioned space, MUST be insulated. Supply
ducting routed through exterior walls MUST be insulated
with 1" insulation to the back of the unit.
4. Supply and return air ducts should be flush with the exterior
wall and sized to fit over the unit duct collars in order to
compress the collar air gasket.
5. If supply duct is flashed to the exterior of a building
onstructed with combustible material, the flashing MUST
c
be insulated in order to maintain the required clearances
to combustible materials. Required clearance is 1/4" for
the first three (3) feet of supply duct.
E. FILTERS
1. One-inch disposable filters are supplied standard in each
available as an option. The filter rack is adjustable to
adapted by bending the retaining brackets. Refer to the
filters.

F. ELECTRICAL POWER
The installer MUST check available power to make certain it
matches the unit nameplate rating and that constant voltage can
be maintained to the unit. Unsatisfactory and unsafe performance
could otherwise result. The local power company should be
contacted about questions concerning power supply.
G. BREAKER/DISCONNECT ASSEMBLY
These units are standard equipped from the factory with a unit
t
disconnect. This is in the form of a circuit breaker (230V models)
or disconnect (460V models). If an optional electric heat kit is to be
installed, follow the instructions included with the heater assembly.

H. ELECTRICAL HOOKUP
The line voltage electrical service can be routed through the right
side panel, the right side of the back panel, or left side panel. Each
area is supplied with two line voltage knock-outs (1/2" – 3/4" and
1" – 1¼"). Low voltage wiring can be routed through the right or left
side panel.

compartment, conduit MUST be used (even though this is a dry
area) to comply with the NEC code. A 11/4" conduit is supplied
for this application. Refer to the ELECTRICAL DATA tables for
minimum wire size and maximum breaker size. All wire sizes listed
under the dual-feed circuit column are based on no more than
three (3) conductors in the same conduit. If two circuits or more
than three (3) conductors are to be routed in the same conduit, the
ampacity of the wire size listed MUST be derated. Refer to Article
310 of the NEC code for adjustment factors. Be sure to install a

condition for which it will be used. For example, a unit to be
installed on a building that is intended to be transported will
require more wall strength than a unit installed at a
permanent site. Existing walls may need additional
reinforcement. NEVER RELY ON EXTERIOR SIDING OR
PLYWOOD TO SUPPORT THE UNIT. Figure 2 at right
represents a typical installation of a single-story stud wall at
a permanent site. Since building materials and techniques
vary with regions and intended use, a building contractor
and/or local building code official MUST be consulted for
suitable construction methods.
2. Locate and attach the lower mounting bracket in the
desired location on the building.
3. Apply a suitable amount of caulk or silicone across the
entire length of the top rain flashing and side mounting
flanges.
4. Remove the flanges on both ends of the pallet and slide the
unit approximately 2” off
into location with fork truck, taking care to align unit with
lower mounting bracket.
5. While allowing a small portion of weight on the lower
bracket, push the unit against the wall and fasten
appropriately.

I. LOW VOLTAGE WIRING
230 volt, 1- and 3-phase units are equipped with dual-primary
voltage transformers for 208/240 volt operation. These models are
factory wired to the 240 volt tap. For 208 volt operation connect the
factory-installed black wires from the 240 volt tap to the 208 volt
tap. The acceptable voltage range of the tap is as follows.
Five (5) conductor thermostat wires should be run from the
thermostat location to the unit. Thermostat wire should be sized as
shown on the table below.
Refer to wiring diagrams for connection details.
Tap Voltage Range
240 Volt 253 - 216
208 Volt 220 - 187
STAGING OF ELECTRIC HEAT
All V Series units with electric heat assemblies above 10 kW may
be wired for single or two-stage heat. These models come factory
wired for single-stage operation. For two-stage operation, remove
the jumper bar from between the W1 and E terminal. Wire the firststage heat to terminal W1. Wire the second-stage heat to terminal
E.
