Location of Unit
Install the unit on a solid, level mounting pad. To minimize
transmission of vibration, the pad should not be in direct
contact with any building walls or foundations.
This unit has been designed to be located outdoors with
sufficient clearance for free entrance to the inlet and
discharge air openings. Adequate service clearance must
also be provided. Refer to Figure 1 for a detailed descrip-
tion of minimum clearances. Position the unit to avoid
direct contact of water, snow or ice from a roof line
overhead.
Avoid placing the unit near quiet areas such as
sleeping quarters or study rooms. Normal operating
sound levels may be objectionable if the unit is placed
near certain rooms.
Electrical Wiring
All field wiring must be done in accordance with the
National Electrical Code recommendations, Canadian
Electrical Code and CSA Standards, or local codes, where
applicable. Refer to the unit rating plate for information
needed for wire sizing and branch circuit protection. An
adequately sized branch circuit disconnect should be
installed, per the NEC, within sight of and readily acces-
sible to the unit. Route properly sized copper conductors
from the disconnect to the unit high voltage connections at
the contactor. A properly sized ground wire must be
connected to the ground screw or wire located in the
control panel. Two low voltage thermostat wires must be
connected to the yellow wires connected to the contactor
coil. Use copper conductors only.
INSTALLATION
General
Read this entire instruction manual, as well as the
instructions supplied in separate equipment, before
starting the installation. Observe and follow all
warnings, cautions, instructional labels and tags.
Failure to comply with these instructions could result
in an unsafe condition and/or premature component
failure.
These instructions are intended as a general guide only
for use by qualified personnel and do not supersede any
national or local codes in any way. The installation must
comply with all provincial, state and local codes as well as
the National Electrical Code (U.S.) or Canadian Electrical
Code (Canada). Compliance should be determined prior
to installation.
This unit has been factory charged with a quantity of
refrigerant (R22) sufficient for a matched indoor coil
and 20 feet of refrigerant tubing. If installed with other
indoor sections or with tubing sets other than 20 feet in
length, adjustments to the total system charge must be
made.
This outdoor unit has been ARI rated with several Arm-
strong matching indoor sections for various types of
installations. To obtain optimum performance, a matched
indoor section must be installed. ARI ratings are based on
properly charged systems running at rated indoor cfm
levels. Ductwork should be specified to insure the correct
indoor airflow is obtainable.
Inspection of Shipment
Upon receipt of equipment, carefully inspect it for possible
shipping damage. If damage is found, it should be noted
on the carrier’s freight bill. Take special care to examine
the unit inside the carton if the carton is damaged. Any
concealed damage discovered should be reported to the
last carrier immediately, preferably in writing, and should
include a request for inspection by the carrier’s agent.
If any damages are discovered and reported to the carrier
DO NOT INSTALL THE UNIT, as claim may be denied.
Check the unit rating plate to confirm specifications
are as ordered.
Limitations
This unit is designed and approved for outdoor use
only.
The outdoor unit must not be installed with any ductwork
in the airstream. The outdoor fan is not designed to
operate against any additional static pressure.
* If extended run times are anticipated below
outdoor temperatures of 65° F, a low ambient kit
must be installed.
