Installation
Unit Inspection
Upon delivery, inspect the unit for damage. Any
damage must be reported immediately to the carrier.
Do not install such an equipment damaged by freight
which determines the integrity and safety of the unit.
Please check the equipment model number to ensure
the unit is appropriately sized for the condensing unit.
If an incorrect unit is supplied, it must not be installed
and it is to be returned to the supplier. The
manufacturer assumes no responsibility for the
installation of incorrectly delivered units. The
evaporator coil contains high-pressure inert gas for
holding charge.

When installing the air handler, take consideration to
minimize the length of refrigerant tubing as much as
possible. Do not install the air handler in a location
either above or below the condenser that violates the
instructions provided with the condenser. Service
clearance is to take precedence. Allow a minimum of
24” in front of the unit for service clearance. When
installing in an area directly over a finished ceiling
(such as an attic), an emergency drain pan is required
directly under the unit. See local and state codes for
requirements. When installing this unit in an area that
may become wet, elevate the unit with a sturdy, non-
porous material. In installations that may lead to
physical damage (i.e. a garage) it is advised to install a
protective barrier to prevent such damage.
This air handler is designed for a complete supply and
return ductwork system. Do not operate this product
without all ductwork attached.
Based upon the actual conditions, if air handler is
installed as Fig. A, the air handler should be concealed
in a specific room or space and make sure the air
handler is not accessible to the general public.
Based upon the actual conditions, if air handler is
installed as Fig. B, make sure that there is enough
space for care and maintenance and the height
between the air handler and ground is above 98.4 in
(2500 mm). And the air handler is not accessible to the
general public. The air handler should be maintained at
a 5° angle to ensure smooth drainage.
