Introduction
Thank you for your r c nt H althy Climat ®Humidifi r purchas . W
sinc r ly appr ciat your busin ss and ar pl as d to add your
nam to our growing list of custom rs. Now, pl as tak a f w min-
ut s and r ad this bookl t. This will familiariz you with th b n fits
you will r c iv from th quipm nt you just purchas d and h lp you
und rstand th routin maint nanc that will b r quir d.
Principle of Operation
You hav purchas d a humidifi r that op rat s on th vaporativ
principl . It will provid th prop r r lativ humidity (s op rating
instructions) all during th h ating s ason. It is v ry possibl that
you hav qu stions conc rning what your n w humidifi r can do for
you, and what you should do to r c iv maximum b n fits from it.
This bookl t is int nd d to answ r th s qu stions.
Th humidifi r op rat s in conjunction with th furnac blow r
motor. Wh n th humidifi r control calls for humidity and th blow-
r motor is op rating, wat r flows to th distribution tray locat d at
th top of th humidifi r. Th wat r is uniformly distribut d across
th width of th tray and through a sci ntifically d sign d syst m of
outl ts. It flows by gravity ov r th humidifi r pad. Dry, hot air is
mov d through th moistur -lad n humidifi r pad wh r vapora-
tion tak s plac . Th now-humidifi d air carri s moistur in vapor
form throughout th hom .
The correct water flow is determined by an orifice in each humid-
ifier. When the humidifier is operating, there will be a small, steady
stream of water to drain, which flushes away most of the trouble-
causing minerals.
Th min rals and solid r sidu (whit dust) not trapp d by th
r plac abl humidifi r pad ar flush d down th drain. Th drain also
liminat s th probl ms caus d by stagnant wat r. This is th most
ff ctiv and l ast xp nsiv m thod to dispos of troubl -causing
min rals.
Troubl -fr p rformanc and minimum maint nanc ar assur d by
th d sign f atur s of th H althy Climat ®Humidifi r. All humidifi r
housing parts that com in contact with wat r ar non-m tal and will
n v r rust or corrod . N ith r h at nor wat r will aff ct th m und r
normal op rating conditions.
Th humidifi r pad, d sign d sp cially for uniform, high vaporation,
and th scal control ins rt also ffici ntly trap min ral d posits
which ar oft n th caus of damag to working parts in ordinary
humidifi rs. Wh n prop rly maintain d, no “whit dust” will b distrib-
ut d through th living quart rs. The humidifier pad must be in good
condition to assure high capacity trouble-free performance. It should
be changed at least annually.
Old r d sign wat r distribution trays hav a granular coating in th
bottom of th distribution tray to provid qual distribution of wat r to
ach of th op nings assuring an v n flow of wat r ov r th humid-
ifi r pad. Do not clean the mineral scale off the bottom of the water
distribution tray at the end of the humidification season. If th granu-
lar coating is r mov d, it is not n c ssary to purchas a n w
distribution tray. You can accomplish th sam uniform p rformanc
by applying a small amount of liquid dishwashing soap ov r th ntir
insid surfac of th wat r distribution tray. This will allow th wat r
to flow v nly through ach of th op nings, provid d th humidifi r
is l v l, in ord r to achi v maximum capacity.
Th curr nt distribution tray incorporat s a synth tic fabric lin r that
r plac s th granular coating and is d sign d to d liv r wat r uni-
formly ov r th ntir top surfac of th humidifi r pad, provid d it is
mount d l v l. It is normal for som min ral d posits to form in th dis-
tribution tray as it dri s out b tw n humidification cycl s. Th s
d posits can actually h lp distribut wat r in th tray, but if th y form
nough to block th op nings, th y should b r mov d as d scrib d
in th “R quir d Maint nanc ” s ction of this manual.

Your n w H althy Climat ®Humidifi r is controll d by a manual
humidifi r control install d ith r in th living ar a or in th cold air

Your humidifi r is part of a syst m that will accurat ly maintain th
RH in your hom . For v ry 1°F chang in outdoor t mp ratur , th
automatic humidifi r control will automatically adjust th indoor r l-
ativ humidity by 0.5% RH. If you would lik to d t rmin th RH in
your hom , follow th s st ps:
1. D t rmin th outdoor t mp ratur .
2. Activat th furnac blow r by s tting your th rmostat fan switch
to th ON position, or by s tting your th rmostat to a high r t mp r-
atur .
3. Turn th control dial s tting to th OFF position. Th n, slowly turn
th dial clockwis until you h ar th sol noid valv click on. Slowly
turn th dial count rclockwis until you h ar th sol noid valv
click off. At this point, mak not of th dial s tting.
4. Locat your dial s tting on Tabl 2. Follow th dial s tting to th
right until it int rs cts with th curr nt outdoor t mp ratur . This
is th RH in your hom und r xisting conditions.
5. R turn th th rmostat and control to th ir original s ttings.
As an example, if the outdoor temperature is 20°F and, follo ing step
3, the humidifier turns off at “5”on the dial range, then the RH in your
home is 35%.
Th automatic humidifi r control will accurat ly control th humidi-
ty in your hom to a maximum of 45% RH and a minimum of 10% RH.
Th valu s of outdoor t mp ratur and dial s ttings may fall in
b tw n or outsid of th list d valu s in Tabl 2. In th s cas s, you
will b abl to approximat your hom ’s actual indoor RH.
Operating Instructions Manual Mode
If an outdoor t mp ratur s nsor has not b n install d with your

tant to k p th humidifi r control s tting at th r comm nd d l v l
in ord r to avoid xc ssiv indoor RH. This will pr v nt th formation
of cond nsation on insid windows (fogging or frost on windows).
For xampl , with an outsid t mp ratur of 20°F, th corr ct s tting
will b 35% RH. If th t mp ratur is xp ct d to fall to 0°F that
v ning, th n adjust th s tting to provid 25% RH s v ral hours
prior to th t mp ratur chang .

will avoid cond nsation on your windows.
Th humidifi r control can b us d to accurat ly d t rmin th RH
in your hom during th wint r. With th furnac blow r op rating at
th h ating sp d, turn th dial to th low st s tting, th n r v rs

Any typ of wat r (hard, soft, hot, or cold) is acc ptabl for us with
th HCWB3 or HCWP3 drain-typ humidifi rs. Hot supply wat r, 140°
maximum, is r comm nd d for all h at pump applications. Th us
of hot supply wat r will also incr as th humidifi r’s capacity.
