Warranty is void unless humidifier is installed by qualified heating and air conditioning contractor due to possible misapplication of product. This product must be installed in compliance with all local, state, and federal codes. Proper humidification and humidity control require that the home be constructed with local codes and good building practices.

WARNING

furnace before installing humidiﬁer.

CAUTION

SHARP EDGES. Use care when cutting and handling

ductwork.

HOT WATER CAN SCALD. Shut o hot water supply before tapping into hot water supply.

SPECIFICATIONS

Humidifier Dimensions:

Width (including solenoid valve): 15-3/8" Height (including drain spud): 15-3/4" Depth: 10-1/4"

Bypass Duct Opening: 6" diameter Plenum Opening: 10"W x 12-3/4"H Water Feed Rate: 3 gph Electrical Data: 24 VAC, 60 Hz, 0.5 Amp Water Panel®: Model 35

INSTALLATION OPTIONS (LEFT HAND DISCHARGE SHOWN)

Aprilaire® Model 600 and 600M can be installed on either the supply plenum or cold air return of a forced air handling system with right hand or left hand bypass duct connections. The humidifier dimensions and serviceability must be considered when selecting the best location for the humidifier.

Hot water is recommended (140°F max) to provide maximum evaporative capacity. It is also recommended when the Blower Activation Feature is used with an Automatic Digital Humidifier Control, or on a heat pump system. The humidifier functions with cold, hot, softened, or unsoftened water.

FREEZING TEMPERATURES CAN BURST WATER PIPES.

• Do not install humidifier where freezing may occur.

CONDENSATION DAMAGE OR MOLD CAN OCCUR.

• Locate return duct mounted humidifier control at least 6" upstream of humidifier, bypass duct connection, or fresh air intake for accurate humidity sensing.

• Locate wall mount humidifier control in areas unaffected by drafts or heat sources for accurate humidity sensing.

• Reduce the setting on the humidifier control if condensation forms on windows or in unheated spaces.

EQUIPMENT DAMAGE MAY OCCUR.

• Do not install humidifier or bypass connection on the furnace jacket.

• Do not connect the transformer to the blower motor wiring.

• Do not install the humidifier or bypass connection on a plenum face at the blanked end of the cooling coil.

• If water pressure exceeds 125 psi, reduce water pressure with devices allowed by local codes.

• Do not use water with temperature greater than 140°F.

• Do not install humidifier on systems with differential pressure greater than 0.4 w.g. between the supply and return plenums.

• When installing the humidifier control on the return duct of a downflow furnace, ensure the blower continues to run after a heat call is satisfied.
