rator coils that are located in any area of a structure where damage to the
building or building contents may occur as a result of an overflow of the
coil drain pan or a stoppage in the primary condensate drain piping. See
accessories section of these instructions for auxiliary horizontal overflow
pan information (model RXBM).

CAUTION
When used on cooling applications, excessive sweating may occur when unit
is installed in an unconditioned space. This can result in property damage.
• Some building codes require extra cabinet insulation and gasketing when
unit is installed in attic applications.
• If installed in an unconditioned space, apply caulking around the power
wires, control wires, refrigerant tubing and condensate line where they enter
the cabinet. Seal the power wires on the inside where they exit conduit
opening. Caulking is required to prevent air leakage into and condensate
from forming inside the unit, control box, and on electrical controls.
• Install the unit in such a way as to allow free access to the coil/filter com-
partment and blower/control compartment.
• Install the unit in a level position to ensure proper condensate drainage.
Make sure unit is level in both directions within 1/8”.

national codes. Latest editions are available from: “National Fire Protection
Association, Inc., Batterysmarch Park, Quincy, MA 02269.” These publications
are:
• ANSI/NFPA No. 70-(Latest Edition) National Electrical Code.
• NFPA90A Installation of Air Conditioning and Ventilating Systems.
• NFPA90B Installation of warm air heating and air conditioning systems.
• The equipment has been evaluated in accordance with the Code of Federal
Regulations, Chapter XX, Part 3280.
