Introduction

Thank you for your recent humidifier purchase. We sincerely appreciate your

business and are pleasedto add your nameto 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.

I. Prindple of Operation

You have purchased a humidifierthat operates on the evaporative principle.

Itwill providethe proper relative humidity (seeoperating instructions) all during
the heating season. It is very possible that you have questions concerning what

your new humidifier can dofor you, andwhat you should do to receive maximum

benefits from it.This booklet is intended to answer these questions.

now-humidifiedair carriesmoistureinvapor formthroughoutthe home.

Thecorrect water flow is determinedby an orifice in each unit.When the

unit is operating,therewill be a small, steadystreamofwater to drain, which
flushesaway mostofthe trouble-causingminerals. Donot use the saddle valve

to regulate the water flow. It is designed to be completely opened or closed.

The minerals and solid residue not trapped by the replaceable humidifier pad
are flushed down the drain. The drain also eliminates the problems caused by
stagnant water. This is the most effective and least expensive methodto dispose

of trouble-causing minerals.

Trouble-free performance and minimum maintenance are assured by the
design features of the humidifier. All 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 humidifier pad, designed especially for uniform, high evaporation, and

the Scale Control Insert also efficiently trap mineral deposits which are often the

cause of damage to working parts in ordinary humidifiers. No "white dust" can
be distributed throughout the living quarters. The humidifier pad must be in good

condition to assure high capacity trouble-free performance. It should be
changed annually.

Older design water distribution trays have a granular coating in the bottom of

the distribution tray to provide equal distribution of water to each of the openings

assuring an even flow over the humidifier pad. Do notcleanthe mineral scale off

the bottomofthe water distributiontray at the end ofthe humidificationseason.

If the granular coating is removed, it is not necessary to purchase a new distri-
bution tray. You can accomplish the same uniform performance by applying a

small amount of liquid dishwashing soap over the entire inside surface of the
water distribution tray. This will allow the water to flow evenly through each of

the openings, provided the unit is level, in order to achieve maximum capacity.

The current distribution tray which incorporates a synthetic fabric liner that
replaces the granular coating, is designed to deliver water uniformly over the

entire top surface of the humidifier pad, provided it is mounted level. It is normal

for some mineral deposits to form in the distribution tray as it dries out between

humidification cycles. These deposits can actually help distribute water in the

tray, but if they form enough to block the openings, they should be removed as

described in the "Periodic Preventative Maintenance" section of this manual.

II. Operating Instructions

Your new humidifier is controlled by a manual humidistat, HumidiTracT"or

ThermidistatTM, installed either inthe living area or in the cold air return.

"Test" Make certain furnace andblower are
operating. Humidifier will operate for one minute.

The relative humidity in your home will

now be accurately controlled to meet

your needs and should not need further

adjustment duringfuture heating
seasons. Make note ofthe dial setting

in the event youtemporarily move the
knob when performing annual

maintenance ofthe Humidifier.
