Offers Exceptional Features

Attractive Styling - Modern design utilizing non-corrosive, high

dependable component in any warm air heating system.

Proper Humidification - Scientifically designed evaporator pad
results in high evaporative output and minimum hard water scale
accumulation.

clogging.

No Moving Parts - The 1042 drain-type humidifier has no
motor, fan or pump to wear out or lime up.

• Properly humidified air feels warmer
allowing you to turn your thermostat
down a few degrees and reduce energy
costs while still keeping your home

General Operating
Principle

• Evaporation takes place as the heated
air from the warm air furnace passes
through the moisture laden
evaporator pad.

• Water is metered through a solenoid
valve then distributed over the pad
by a trough at the top of
the humidifier.

• Water not evaporated drains from
the bottom of the humidifier
carrying off troublesome minerals.

• Humidified air is then returned
to the heating system to enter the
living area.

Clean Operating - The 1042 is 100% evaporative. There is no
mineral dust to disturb the household.

Manual Air Shuttle - Closes bypass during summer cooling sea-
son. The air shuttle may be used to control humidifier output,
however, a humidistat is recommended.

Dependable Solenoid Valve - Has a monel wire mesh filter to
protect the precision-machined Teflon flow-control orifice.

Reversible Installation - Right or left-hand take-off may be
installed on up-flow, counter-flow or horizontal-flow furnaces.
