INSTALLATION
General
Read this entire instruction manual, as well as the
instructions supplied in separate equipment, before
starting the installation. Observe and follow all warn-
ings, 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.
4HP16LT condensing units use R410A which is an
ozone-friendly HFC refrigerant. This unit must be installed
with a matching indoor coil and line set. A filter drier
approved for use with 410A is installed in the unit.
IMPORTANT: This product has been designed and manu-
factured to meet ENERGY STAR criteria for energy effi-
ciency when matched with appropriate coil components.
However, proper refrigerant charge and proper air flow are
critical to achieve rated capacity and efficiency. Installation
of this product should follow the manufacturer's refrigerant
charging and air flow instructions. Failure to confirm
proper charge and airflow may reduce energy effi-
ciency and shorten equipment life.
When servicing or repairing HVAC components, ensure
the fasteners are appropriately tightened. Table 1 shows
torque values for fasteners.

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.
Location of Unit
Outdoor units operate under a wide range of weather
conditions; therefore, multiple factors must be considered
when positioning the unit. The unit must be positioned to
give adequate clearances for sufficient airflow and servic-
ing. Refer to Figure 1 for installation clearances.
Installation Clearances
36 * "
* A service clearance of 30" must be maintained on
one of the sides adjacent to the control box.
Clearance to one of the other three sides must be
36". Clearance to one of the remaining two sides
may be 12" and the final side may be 6".
A clearance of 24" must be maintained between units.
48" clearance required on top of unit. Maximum soffit
overhang is 36".
•
Place a sound-absorbing material, such as Isomode,
under the unit if it will be installed in a location or
position that will transmit sound or vibration to the
living area or adjacent buildings.
•
Install the unit high enough above the ground or roof
to allow adequate drainage of defrost water and
prevent ice buildup.
•
In heavy snow areas, do not locate the unit where
drifting snow will occur. The unit base should be
elevated above the depth of average snows.
