I. PRINCIPLE OF OPERA TION With your purchase of a humidification system, you have invested in a humidifier that operates on the evaporative principle – nature’s own way of adding moisture – and will provide the proper relative humidity all during the heating season.
- 2 - There are some homes where drain facilities are not accessible or available. For these situations, or where high water hardness is not a problem, specially designed Aprilaire Humidifiers, Models 448 and 445, are available, incorporating a water recirculating system.
II. OPERA TING INSTRUCTIONS There are 2 possible modes of operation of your Aprilaire Humidifier Control and an explanation of both modes follows: Automatic Mode: (Manual Mode-see pg 5) Your Aprilaire Humidifier Control is installed in the cold air return.
Your Aprilaire Automatic Humidifier, is a high precision system that will accurately maintain the relative humidity in your home. For every 1º change in outdoor temperature, the control will automatically adjust the indoor relative humidity (RH) by 1 / 2 %.
- 5 - Manual Mode: (Automatic Mode – see pg 3) Your Aprilaire Humidifier Control is installed in the cold air return. It is important to anticipate a drop in outdoor temperature and reduce the setting accordingly to avoid excessive condensation. For exam- ple, with an outdoor temperature of 20 ° the correct setting will be 35% relative humidity.
- 6 - To check the humidifier operation, set the knob to “ test ” , make sure that the water saddle valve is open and that there is electricity to the unit. Generally, the furnace blower motor must be operating for the Aprilaire Humidifier to function.
- 7 - Additional Information Be sure to keep fireplace dampers closed when not in use. They provide an excellent escape route for heat, as well as humidity. Humidity is lost at an even faster rate than heat because water vapor tends to seek its own level and your humidifier would not be able to replace it even when running at full capacity.
- 8 - IV . ANNUAL MAINTENANCE For best performance, we recommend that you r eplace the water panel evaporator in your Aprilaire Humidifier annually . • Call the installer of your Aprilaire Humidifier. This information is often found on your equipment.
