CAUTION
1. Do not install humidifier where freezing temperatures
could occur. The water line could freeze and crack
causing water damage to the home.
2. Do not install humidifier on the furnace jacket.
3. Do not install humidifier on a plenum face where the
blanked off ends of the cooling coil will restrict air
movement through the humidifier.
4. Do not set humidity level above recommended or to
recommended level if condensation exists on inside
windows of any unheated space, as condensation
damage may result. Excess humidity can cause
moisture accumulation which can allow the possibility
for mold growth in the home.
5. Do not connect the Model 700 power cord to multi-speed
furnace blower motors or blower motors other than 120 VAC.
Premature component failure may result. Use Research
Products Corporation Model 50 Current Sensing Relay.
6. When installing Aprilaire Humidifier Control on a downflow
furnace, ensure blower continues to run after a heat call is
satisfied to eliminate high temperatures from damaging the
Control.
7. Do not install humidifier where water pressure exceeds
125 psi, since damage to the humidifier may result. Follow
codes in effect concerning pressure reduction.
8. Do not install humidifier on the supply plenum where static
pressure exceeds 0.4 in. wg.

NOTES
1. The Model 700 is not
suitable for installation
on ducts with horizontal
airflow. Performance
will be reduced.
2. When installing Aprilaire
humidifier on a heat
pump system, use hot
water. The heated
water supplements the
reduced supply air
temperature as added
heat for evaporation.
