garages, utility rooms or parking areas because of the danger of carbon monoxide (CO)
poisoning resulting from the exhaust emissions. If a furnace or air handler is installed in
an enclosed area such as a garage, utility room or parking area and a carbon monoxide
producing device is operated therein, there must be adequate ventilation directly to
outside.
This ventilation is necessary to avoid the danger of CO poisoning which can occur
if a carbon monoxide producing device continues to operate in the enclosed area.
Carbon monoxide emission can be (re)circulated throughout the building if the furnace
or air handler is operating in any mode.
CO can cause serious illness including permanent brain damage or death.
4 Installation
4.1 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.
4.2 Location
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
This air handler is designed for indoor installation only. Do not install
