Upflow Units

• 1). Turn off all power to your Payne furnace by turning off the switch on the side of it.
  
  
• 2). Remove both access doors on the front of the furnace. Lift up on them and then pull straight off.
  
  
• 3). Slide the filter retainer wire to the left, and lift it out of the bracket.
  
  
• 4). Lift up on the filter and pull straight out. Turn the dirty side, or bottom, up to prevent dirt from falling off the filter.
  
  
• 5). Wash the filter with cold water and mild liquid detergent. Spray water through the filter in the opposite direction that the air flows through. The filter will have arrows on it denoting airflow.
  
  
• 6). Slide the filter back into place while making sure the airflow arrows point in the right direction, which is up toward the furnace blower.
  
  
• 7). Lower the filter retainer wire into the bracket and lock it into place by sliding it to the right.
  
  
• 8). Put the access doors back on the furnace and turn the power back on.
  
  

Downflow Units

• 1). Turn off all power to your Payne furnace by turning off the switch on the side of it.
  
  
• 2). Remove the two screws holding the blower access door in place and remove the door.
  
  
• 3). Tip the top of the left-side filter to the right, or center of the unit. Raise the filter out of the channel it sits inside, and lower it alongside the blower. Pull it out of the compartment.
  
  
• 4). Lift the right-side filter out of the channel it sits inside, and lower it along side the blower. Remove it from the compartment.
  
  
• 5). Wash the filters with cold water and mild liquid detergent. Spray water through the filters in the opposite direction that the air flows through. The filters will have arrows on them denoting airflow.
  
  
• 6). Slide the filters back into place by reversing the removal steps. Remember to install the right-side filter first and orient them in the correct direction. Airflow on these units is down, or toward the blower.
  
  
• 7). Put the blower access door back into place and secure with the two screws you removed. Turn the power back on to your furnace.
