WATER CONNECTION

Water supply for the humidifier should be taken from
a nearby hot water line but cold water is acceptable.
All  water  connections  should  be  made  at  ground
floor  level.    Do  not  use  any  water  line  served  by  a
water softener.  If your home has a water softener,
make  the  water  connection  up  stream  of  the  water
softener.  A water softener is not a de-mineralizer.  It
merely exchanges various hard-ions for soft-ions in
the water.  These soft-ions or minerals, will build up
in  the  transfer  media  in  the  humidifier,  causing  the
need for more frequent servicing.  The evaporation
of softened water may also produce a white powder
which  may  be  carried  in  to  the  duct  system  and
ultimately in to the home.  The saddle tapping valve
should be mounted on top of, or on the side of the
water line.  If the valve is installed on the bottom of
the  water  line  it  could  clog  with  sediment  from  the
water  line.    Refer  to  the  instructions  on  the  saddle
valve package and proceed as follows.  For copper
water  lines  the  valve  is  self  piercing.    Mount  the
saddle valve to the top or side of the water line, then
turn  “T”  handle  to  the  clockwise  until  it  stops  to
pierce and seat the valve to the pipe.  Open to flush
the  valve  and  close  it  again.   Then  connect  plastic
water  line  from  the  valve  to  the  humidifier  making
sure not to kink it or run it near any hot flue pipes.
Connect  water  line  to  valve  and  humidifier  with
supplied hardware.  Now open the saddle valve turn-
ing the tee handle counter clockwise until fully open.
Check  for  water  leaks  and  repair  as  necessary.

Attic installations are not recommended

INSTALL DOOR AND EVAPORATIVE PAD

DRAIN CONNECTION

Make sure the evaporative pad is positioned in the
door correctly.  The black mark on the edge  of the
pad indicates the top.  The pad slides into the door
and rests against the four legs located inside.

Position  the  bottom  edge  of  the  door  in  the  tray
located on the lower opening in the housing.  Then
simply  push  the  top  of  door  closed  until  is  has
snapped into place.   To remove door just push down
on the two tabs located at the top of the door and pull
the door away from the housing.

Connect  the  1/2”  plastic  tubing  to  the  drain  spout
and secure it.  The spout is located at the bottom of
the housing.  Keep the tubing as short as possible
and  avoid  sharp  bends.    The  drain  line  should  be
routed  on  a  continous  downward  slope  and  into  a
suitable drain.

WARNING: failure to connect the

drain tubing could result in a flood.

SETTING THE HUMIDISTAT

Most people feel comfortable between 35% to 45%
RH, but the proper relative humidity for your home
depends  upon  many  factors  such  as  outside  air
temperature,  type,  and  placement  of  insulation,
vapor  barrier,  effectiveness  of  weather  stripping,
type  of  windows  and  doors  (including  frames  and
jams),  and  whether  storm  windows  and  doors  are
used.  With all of these variables it is nearly impos-
sible to recommend a proper humidity setting.  The
best humidstat setting is one that you are comfort-
able with.  Also, as the outdoor temperature fluctu-
ates,  it  may  be  necessary  to  adjust  the  humidity
level a few times during the heating season.  Refer
to the “Relative Humidity Chart” as a starting point
for  your  proper  humidistat  setting.    Generally,  in  a
tighter  and  better  insulated  house,  the  humidistat
may  be  set  higher  than  in  a  drafty,  uninsulated
house.
