Lennox HEALTHY CLIMATE WB2-12 Operating Instructions

OPERATING INSTRUCTIONS FOR MODELS WB2-12, WB2-17, WB2-17A, WP2-18 & WP2-18A
Introduction
Thank you for your recent Lennox Healthy Climate
chase. We sincerely appreciate your business and are pleased to
add your name to our growing list of customers. Now, please take a
few minutes and read this booklet. This will familiarize you with the
benefits you will receive from the equipment you just purchased
and help you understand the routine maintenance that will be
required.
Electrical Shock Hazard
Can cause injury or death.
Disconnect all electrical power supplies before
servicing.
Shut off water supply before disconnecting or
tapping into any water supply line.
CAUTION
Risk of Equipment Damage
After humidifier installation is completed, turn water supply
back on.
Principle of Operation
You have purchased a humidifier that operates on the evaporative
principle. It will provide the proper relative humidity (see operating
instructions) all during the heating season. It is very possible that
you have questions concerning what your new humidifier can do for
you, and what you should do to receive maximum benefits from it.
This booklet is intended to answer these questions.
The humidifier operates in conjunction with the furnace blower
motor. When the humidistat calls for humidity and the blower motor
is operating, water flows to the distribution pan located at the top of
the unit. The water is uniformly distributed across the width of the
pan and through a scientifically designed system of outlets. It flows
by gravity over the evaporative media. Dry, hot air is moved through
the moisture-laden evaporative media where evaporation takes
place. The now-humidified air carries moisture in vapor form
throughout the home.

Risk of Equipment Damage
Do not use the saddle valve to regulate water flow.
It is designed to be completely opened or closed.
The correct water flow is determined by an orifice in each unit.
When the unit is operating, there will be a small, steady stream of
water to drain, which flushes away most of the trouble-causing
minerals.
The minerals and solid residue (white dust) not trapped by the
replaceable evaporative media are flushed down the drain. The
drain also eliminates the problems caused by stagnant water. This
is the most effective and least expensive method to dispose of trou-
ble-causing minerals.
Trouble-free performance and minimum maintenance are assured
by the design features of the Lennox Healthy Climate
unit housing parts that come in contact with water are non-metal
and will never rust or corrode. Neither heat nor water will affect
them under normal operating conditions.
The evaporative media, designed especially for uniform, high evap-
oration, and the scale control insert also efficiently trap mineral
deposits which are often the cause of damage to working parts in
ordinary humidifiers. When properly maintained, no "white dust"
will be distributed through the living quarters. The evaporative
media must be in good condition to assure high capacity trouble-
free performance. It should be changed at least annually.
The granular coating in the bottom of the distribution tray is
designed to provide equal distribution of water to each of the open-
ings assuring an even flow of water over the evaporative media. Do
not clean the mineral scale off the bottom of the water distribution
tray. The scale provides an excellent track for the water to follow.
This is actually what we try to simulate with the synthetic coating in
the bottom of the tray. If the coating is removed, it is not necessary
to purchase a new distribution tray. You can accomplish the same
uniform performance by applying a small amount of liquid dish soap
over the entire lower surface of the water distribution tray. This will
allow the water to flow evenly through each of the openings.
