4. Installation
4.1 Installation Checklist
IMPORTANT: Prior to installation of the
DH90, the following checklist should be
reviewed.
The DH90 can be installed in a variety of locations
to meet the owner’s needs, and integrate with
existing forced air systems or existing ductwork
if desired. Choose a location with consideration
to accessibility for service, drain availability, and
power outlet location.
4.1A Power Accessibility
Unit should be located in an area where the cord’s
length (10') should easily reach a 115 VAC electrical
outlet with a minimum of a 15 A circuit capacity.
4.1B Accessibility
The installed DH90 should have at least 14 inches
of clearance in the front of the device to service
the filter.
4.1C Support Structure and Suspension
Place the DH90 on supports to raise the base of the
unit. Do not place the DH90 directly on structural
building members without vibration absorbers or
unwanted noise may result.
The DH90 may be suspended from structural
members by supporting the entire base of the unit
via cross members, rigid frame, or the like. Do not
hang the DH90 from the cabinet. Remember to
place a drain pan under the unit if it is suspended
above a finished area or above an area where
water leakage could cause damage.
4.1D Sizing Chart
*This sizing chart is based on extreme climates where Rh
levels are between 70 and 90% outdoor Rh. For less extreme
climates then larger homes can be adequetely served. Actual
requirements may vary.
4.2 Electrical Requirements
WARNING: Installation must be performed
by a qualified service technician and must
comply with local codes. Remove power to
the device before installing or servicing the
device. Failure to connect the device
according to these instructions may result in
damage to the device or the controls.

The DH90 plugs into a common grounded 115VAC
outlet. The device draws 6.2 Amps under normal
operating conditions. If used in an area which
may become wet, a ground fault interrupter (GFI)
protected circuit is recommended.
IMPORTANT: Do not install the humidistat
where it may not accurately sense the relative
humidity such as near HVAC supply registers,
near exterior doors, on an outside wall, near
a window, or near a water source.
Refer to Section 6 for typical hookup diagrams.
Some of the control wires leaving the DH90 may
not be used with certain installations and should
be left unconnected with wire nuts taped onto the
stripped ends for safety.
4.3 Condensate (Water) Removal
The DH90 removes a large amount of moisture
from the air and the device must be connected to
a drain line that will carry away the excess water. A
trap in the drain line is recommended and may be
required by some local codes.
The drain line should be connected to the 3/4" male
pipe thread adaptor on the front of the DH90.
Care should be taken to install the drain line with
a continuous slope of 1" per 10' to assure proper
water removal.
4.4 Ducting
IMPORTANT: When connecting ventilation
duct, remove the label and 6" round
insulation plug from the ventilation duct
opening. If not using ventilation feature,
leave the insulation intact.
For the ideal installation, draw air from the central
part of the home and return it to the isolated areas
of the home like the bedrooms, den, utility room, or
family room. See Figure 1. Alternative installation
option can be completed by drawing air directly
from the return ducting and distributing through
the supply air to the home.
Another installation option is ducting directly from
the return and distributing directly back into the
system's return. See Figure 2. Fresh air ventilation
is optional and does not have to be ducted in order
for the DH90 to properly function.
4.4A Fresh Air / Supply Air
IMPORTANT: DO NOT draw air directly from
the kitchen, laundry, or isolated basement.
Air may be drawn from a basement that is open
to the home. All flexible ducting connected to the
DH90 should be UL listed.
A short piece of flexible ducting on all DH90 duct
connections is recommended to reduce noise
and vibration transmitted to rigid ductwork in the
structure. Ducting the DH90 as mentioned requires
consideration of the following points:
Figure 1: Ducting to isolated areas. Figure 2: Ducting from main return trunk to supply trunk.

• Duct Sizing: For total duct lengths up to
25', use a minimum 10" diameter round or
equivalent rectangular. For longer lengths,
use a minimum 12" diameter or equivalent.
Grills or diffusers on the duct ends must
not excessively restrict airflow.
• Isolated Areas: Effective dehumidification
may require that ducting be branched to
isolated, stagnant air flow areas.
Use 8" or larger diameter branch ducting to each
of two or three areas, use 6" or larger to each of
four or more areas. Provisions must be made to
provide airflow from supply locations to central return
location. Proper air distribution is important to ensure
even humidity control throughout the structure.
4.4B Ducting for Fresh Air — Option
Fresh air may be brought into the structure by
connecting an insulated duct from outside the
structure to the 6" inlet of the DH90. Advantages
of this form of ventilation include:
1. Outside air is filtered before entering the
building.
2. Outside air will be dehumidified before
entering if the DH90 is running in
dehumidification mode.
3. Drawing air from outside and blowing
inside aids in slightly pressurizing the
structure. This helps prevent dirty and
humid air from entering elsewhere.
Exhaust fans are recommended in the
bathrooms and kitchen.
An insulated 6" diameter duct is generally
sufficient to provide up to 75 CFM of outside air.
Large quantities of outside air will impact DH90
performance positively or negatively, depending
upon the inside and outside air conditions.
The outside air duct should be connected to the 6"
round collar on the side of the unit. The amount of
outside air can be restricted by the blade damper
in the 6" collar. The actual amount of ventilation
air being delivered through the ventilation ducts
must be measured in each installation. Refer to the
instructions provided with the W8150 Ventilation
Control for proper setup instructions.
4.4C Installation in a Basement or Crawl Space
with an Existing Forced Air HVAC System
Install a separate 10" return for the DH90 in a central
area of the structure. Optional: Duct the supply of
the DH90 to a 10" x 10" x 10" tee/damper, adjusted
to 20% open to the basement. Duct the other side
of the tee to the air supply of the existing HVAC
system with a backdraft damper. Connect a duct
from outside to the 6" collar of the DH90 if you
wish to provide ventilation air. See Figure 3.

Instead of installing a separate return to the DH90,
and if the existing system has multiple returns,
it is possible to select one to disconnect from
the existing forced air system and use it for the
dedicated DH90 return. Always select a return from
a central location in the structure in an area that is
always open to the rest of the structure. Do not use
a return from a room that may have its door closed
much of the time.
4.4D Installation in an Attic with an Existing
Forced Air HVAC System
IMPORTANT: ALWAYS install a catch pan
with a drain or float interrupt for condensate
under the DH90 in an attic or condensate
may damage the living space below.
The interrupt switch should be installed in series
with the field wire that connects the blue lead
from the DH90 to the dehumidistat. If overflow
occurs, this switch opens the compressor control
circuit and stops water production before the
catch pan overflows. The DH90 will continue to
ventilate or circulate air as normal, but will not
dehumidify until this switch closes.
One method of installation is to create a separate
return for the DH90 in a central area of the
structure. Duct the supply of the DH90 to the air
supply of the existing HVAC system. Connect an
insulated duct from outside to the 6" collar of the
DH90 if you wish to provide fresh air. Adjust a
damper in the duct to provide the desired amount
of fresh air. See Figure 4.
4.4E Installation in a Structure with No Existing
Forced Air HVAC System
When installing the DH90 in a structure that does
not have a forced air HVAC system, a single return
for the DH90 should be installed in central open
area of the structure.
DO NOT locate the return in a bathroom or a
kitchen. The supplies of the DH90 should be
located in the remote areas of the structure (such
as bedrooms, den, etc.). By ducting this way, the
air inside the structure will circulate through the
DH90 to be filtered and dehumidified.
6" diameter duct is recommended for branches to
the bedrooms, 8" diameter duct is recommended
for branches to larger areas. Connect an insulated
duct from outside to the 6" collar of the DH90 if
you wish to provide ventilation. See Figure 5.

4.5 Noise Abatement
A length of 10' or more of acoustical flex ducting
on the outlet of the DH90 will reduce air noise from
the fan. A length of flexible ducting on all DH90
duct connections is recommended to reduce noise
transmitted to rigid ductwork in the structure.
5. Maintenance
5.1 Air Filter
The DH90 is equipped with a MERV 11 media
filter. This filter should be checked every three
months and replaced every six months. Operating
the unit with a dirty filter will reduce dehumidifier
capacity and efficiency and may cause the com-
pressor to cycle off and on unnecessarily on the
defrost control.
CAUTION: Operate the unit only with a
genuine Honeywell filter installed to assure
proper performance of the unit.
5.2 Optional Fresh Air Intake
Check and clean the screen on the outdoor fresh
air intake port seasonally. The screen may become
plugged during the seasons when there are many
particles in the outdoor air.
