Installation
Please read and save these instructions.
The Armstrong HumidiClean humidifier converts ordinary tap water or purified water to steam for
distribution to raise the relative humidity level.
To allow HumidiClean to function to its full capability, be certain to install in accordance with
Armstrong recommendations.
Danger!
Electrical Shock Hazard High Voltages Exist Inside the Humidifier!
To protect yourself and others from accidental shocks:
1. Keep the humidifier locked during normal operation and store the key in a safe location
away from the humidifier.
2. Always disconnect the power supply at the circuit breaker or safety switch before
opening any covers or doors.
3. Before servicing the humidifier, learn where the high voltage parts are. The contactor
terminals and high voltage fuse blocks, along with the power module and heating
elements have shock potential. Keep hands and metal tools away from these areas
when power to the unit is on.
Pre-Installation
1. Check Shipment. A claim should be filed with the transportation company, (and
reported to Armstrong), if any items are missing or damaged.
2. Check Local Codes. The installation of HumidiClean should be in accordance with all
applicable building, plumbing, and electrical codes.
