PRE-INSTALLATION INSTRUCTIONS
Carefully read all instructions for the installation prior to install-
ing product. Make sure each step or procedure is understood and
any special considerations are taken into account before starting
installation. Assemble all tools, hardware and supplies needed
to complete the installation. Some items may need to be purchased
locally. Make sure everything needed to install the product is on
hand before starting.
Before attempting any installation, the following points should
be considered:
• Structural strength of supporting members
• Clearances and provision for servicing
• Power supply and wiring
• Air duct connections
• Drain facilities and connections
Installation Clearances
Place this unit as close to the space to be air conditioned as
possible. These units are U.L. listed for installations with zero
clearance to combustible materials. If this unit is installed in a
removable ceiling panel, ensure adequate space is available for
servicing. Run ducts as direct as possible to supply and return
outlets. Use non-flammable weatherproof flexible connectors on
both supply and return connections at unit to reduce noise trans-
mission.
Ducting
Duct work should be fabricated by the installing contractor in
accordance with local codes. Use industry manuals such as such
as NESCA (National Environmental Systems Contractors Associa-
tion, 1501 Wilson Blvd., Arlington, Virginia 22209) as a guide
when sizing and designing the duct system.
To ensure correct system performance, the ductwork is to be sized
to accommodate 375-425 CFM per ton of cooling with the static
pressure not to exceed 0.5” W.C. Inadequate ductwork that re-
stricts airflow can result in improper performance and compres-
sor or heater failure
T O PREVENT THE RISK OF PROPERTY DAMAGE , FIRE , CARBON MONOXIDE
POISONING
, EXPLOSION , PERSONAL INJURY , OR DEATH , DO NOT
CONNECT DUCTWORK TO ANY HEAT PRODUCING DEVICE SUCH AS A
FIREPLACE INSERT OR STOVE .
