Air Handlers
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 comes pre-charged with .55 lbs (8.8 oz)
of R410A gas.
4.2 Location
This air handler is designed for indoor installation only. Do not install it outdoors.
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 2500mm. And the air handler is not
accessible to the general public.
