CARBON MONOXIDE POISONING HAZARD
Special Warning for Installation of Furnace or Air Handling Units in Enclosed Areas such as Garages, Utility Rooms or Parking Areas Carbon monoxide producing devices (such as an automobile, space heater, gas water heater, etc.) should not be operated in enclosed areas such as unventilated 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, direct outside ventilation.
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 emissions can be (re)circulated throughout the structure if the furnace or air handler is operating in any mode.
CO can cause serious illness including permanent brain damage or death.

Standard Air handler Installation

WARNING
HKS ELECTRIC HEATER KITS MAY ONLY BE INSTALLED IN ARUFXX14YY, ARPTXX14YY, ASUFXX14YY, ASPTXX14YY, AVPTXX14YY, DVXXPTC14YY MODELS (WHERE XX IS THE TWO- DIGIT SIZE AND YY ARE REVISION LETTERS).
WARNING
ONLY INSTALL HEATER KITS INTO AN AIR HANDLER THAT ARE LISTED AS APPROVED ON THE RATING PLATE OF THE AIR HANDLER.
WARNING
TO PREVENT PERSONAL INJURY OR DEATH WHEN INSTALLING IN A GARAGE, THE ELEMENT MUST BE AT LEAST 18” ABOVE THE FLOOR.
CAUTION
TO AVOID PROPERTY DAMAGE OR PERSONAL INJURY DUE TO FIRE, USE ONLY COPPER CONDUCTORS.

1. Remove the upper access panel from the air handler.

2. Remove and retain the four (4) screws securing the cover plate. Remove and discard the cover plate.

3. For electric heat kits with circuit breakers, remove the two screws securing the circuit breaker mounting plate to the electric heat face plate.
   NOTE: The circuit breakers for the 25kW are placed separately in the carton and are not attached to the heater plate.

4. Slide the electric heat kit into the opening in the air handler, making sure the direction of airflow decal attached to the electric heat face plate is pointing in the correct direction, and secure the electric heat face plate using the screws removed in Step 2. Use
   caution to not bend or damage the electric heating elements, the limit switches or fuses during this process. See Figure 1.

5. For downflow applications with electric heat kits that have circuit breakers, the circuit breakers must be rotated 180 degrees (such that the ON position will be with the circuit breaker handles up). To do so, remove and retain the 2 screws securing the circuit breaker clamps, rotate the circuit breakers and clamps 180 degrees, then use the same 2 screws to re-secure the circuit breakers. See Figure 2.

6. For all electric heat kits with circuit breakers, mount the circuit breaker mounting bracket as shown in Figure 3, using the supplied screws. Insert the four (4) screws as shown in Figure 3 (two through the control panel flange and two into the cabinet corner
   post).
