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 or bypass connection on the
furnace jacket.
3. Do not install humidifier or bypass connection 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 Model 600M or 600A
transformer to blower motor wiring.
Premature component failure may result.
6. When installing Humidifier Control on
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 systems with
greater than 0.4 in. wg pressure differential
between supply and return plenums.
RISK OF PROPERTY AND EQUIPMENT DAMAGE.

NOTE
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.
The current Model 600 is identical to the previous Model 600A (except the 600A came with a 2nd spare water panel).
Aprilaire has not updated this manual from the 600A.
