GeneralAire GF5500 Steam Humidifier: 4 Step Process Before Installation

Step 1: Calculating Gallons Per Day

Follow the formula below to understand the GPD (Gallons Per Day) needed for your home.

Total Square Footage (including Basement) x Average Ceiling Height = Number
That Number x Relative Humidity x 1.05 per Fireplace in Home = Humidity Load (PPH)
Humidity Load x 2.88 (GPD conversion) = Desired Gallons Per Day

Please reference section 1.3 of the Installation Manual for more clarity on GPD calculation.

Use this chart to identify your RH (Relative Humidity) and Furnace Heat running temperature.

Step 2: Test Water Conductivity Using the AP-2 Conductivity Tester

This step is particularly important for municipal water, especially if it is Lake or Well water.

Follow these steps to ensure the 5500 Steam Humidifier can be installed:

1. Fill a glass with one cup of water from the steam humidifier water supply (Refer to Figure A).
2. Turn the AP-2 tester on. Insert the tester into the glass of water (Refer to Figure B).
3. Ensure that the GF5500 Steam Humidifier can be used by correlating the results with GF5500 specifications.

Step 3: Configure 5500 for Amps/Voltage

Follow Section 4.4 in the Install Manual to configure the 5500 for Amps/Voltage.

Visit the GeneralAire website at www.GeneralAireIAQ.ca or check your physical copy of the GF550 Installation Manual. Proceed to section 4.4 (Page 20) titled "Initial Configuration".

If Necessary: To change Maximum Production, follow Section 5.3 (Page 23).

Step 4: Use RMB for Applications Without Duct Work or Air Handler Units

Use the Remote Mount Blower (RMB) when an application does not have duct work or an air handler unit.
