CAUTION! — This symbol means
important instructions. Failure to heed them can result
in injury or material property damage.
2. Installation
2.1 Location
SAKURA Dry-boy is designed to be installed indoorss and is ideal for
unfinished and finished basements.
CAUTION!
• Installation outdoors, or near a pool or spa will void
factory warranty.
•
2.1A In humid area, no ducting.
The simplest installation is to place SAKURA Dry-boy in the humid
area with no ducting. The air inlet on top & outlet on the side
must be at least 1’ from walls and other obstructions to air
flow.
2.1B In humid area, duct inlet and/or outlet.
If the humid area is very large or has high ceilings,
dehumidification can be improved by adding an inlet and/or
outlet duct to circulate and destratify stagnant areas. For a
large area, add inlet or outlet ducting to create flow across the
area’s greatest length. For areas with ceilings higher than 12’,
use an inlet duct to draw warm, moist air from near the ceiling.
See section 2.4 for attaching duct collars & ducting.
2.1C In A Remote Area, Duct Inlet & Outlet.
It is often desirable, in finished areas, to install SAKURA Dry-boy
in an adjacent equipment room or unfinished area. Air is
transferred between the humid room and the unit via ducting.
The factory-mounted humidity control on SAKURA Dry-boy
cabinet will sense the humidity in the humid room accurately
enough with this installation method.
2.1D In A Remote Area, Duct Outlet Only.
A simpler remote installation method than above uses ducting
between SAKURA Dry-boy discharge and the humid room;
SAKURA Dry-boy inlet draws air from the room in which it’s located.
This works well if there is an adequate air flow path between the
two rooms; i.e. high door undercut, louvered door or wall grill.
There are several potential disadvantages to using this method.
First, humid air is drawn into the room where SAKURA Dry-boy is
located. Second, to accurately sense humidity, the blower in
SAKURA Dry-boy may need to run continuously to draw air from the
humid room into SAKURA Dry-boy room. Third, a slight negative
pressure is created in the room with SAKURA Dry-boy which could
backdraft open combustion devices located there. If such devices
are present, call the factory for specific instructions before using
this installation method or consider the option 2.1E below.
2.1E In A Remote Area, Duct Inlet Only.
When SAKURA Dry-boy is located in a room separate from the
main area to be dehumidified, it may be desirable to dehumidify
and/or slightly pressurize that room. Pressurization assures
that open combustion devices do not backdraft . This can be
accomplished by installing a duct from the humid room to
SAKURA Dry-boy inlet and by allowing SAKURA Dry-boy to discharge
dehumidified air into the room in which it’s located. An
adequate air flow path must exist between the two rooms for
this method to work well.
2.2 Electrical Requirements
SAKURA Dry-boy plugs into a common grounded outlet on a 15 Amp
circuit. It draws between 6 and 7 Amps under normal operating
conditions.
2.3 Condensate Removal
Condensate drains by gravity via the clear hose extending from
the unit. Route hose to a floor drain, sump pump, or drainage
system. Use care to keep the hose as flat to the floor as possible.
Excessive humps or kinks will prevent proper drainage.
If SAKURA Dry-boy is located too far from a floor drain for the
attached hose to reach, 1/2" PVC pipe can be used to extend
it. It is commonly available in 10’ lengths from building supply,
plumbing and hardware stores. It will slide tightly inside the end of
the drain hose.
If more than one length of pipe is required, they can be joined with
a short piece cut from the end of the drain hose.
2.4 Ducting
2.4A Optional Ducting
An inlet shroud with an 8" round collar and an 8" round
exhaust collar are available from the factory that will allow
round ducting to be attached to the inlet and/or outlet of
SAKURA Dry-boy
2.4B Ducting for Dehumidification
Ducting SAKURA Dry-boy as mentioned in sections 2.1B-2.1E
requires consideration of the following points:
Duct Sizing: For total duct lengths up to 25 feet, use a
minimum 8" diameter round or equivalent rectangular. For
longer lengths, use a minimum 10" diameter or equivalent.
Grills or diffusers on the duct ends must not excessively restrict
air flow. Isolated Areas: Effective dehumidification may require
that ducting be branched to isolated, stagnant areas. Use 6"
diameter branch ducting to each of two or three areas, use 4"
to each of four or more areas.
3. Dehumidifier Operation
3.1 Humidity Control
The dehumidifier will run continuously until relative humidity
(RH) is reduced to the desired humidity level using the electronic
controlller. Setting the electronic humidity controller to lower RH
levels will NOT increase the unit’s dehumidification rate - it will
simply run longer to reduce the area’s RH to the setting.
SAKURA Dry-boy unit (and refrigerant based dehumidifiers in general)
will reduce a warm space’s RH to a lower level than that of a cool
space. For example, SAKURA Dry-boy may reduce an 80° F space to
30% RH. However, if the same space is 65° F, it may only reduce
it to 40% RH. It is therefore pointless to set the electronic humidity
INSTALLER'S AND OWNER'S MANUAL
3Installer’s & Owner’s Manual

controller to excessively low levels in cool rooms. Doing so will
result in long periods of ineffective dehumidifier run time. An ideal
setting is 55%, which prevents mold growth.
3.2 ON/OFF: Pressing the ON/OFF button once will power up the
control system and illuminate the RUN LED. The unit will now
operate in either DEHUMIDIFY or FAN MODE. Pressing the ON/OFF
button again will return the unit to STANDBY MODE. The RUN LED
will flash.
3.3 MODE: Use the MODE button to select DEHUMIDIFY or FAN
mode of operation.
3.4 UP/DOWN ARROWS: Pressing the UP/DOWN arrow buttons
will display and change the desired %RH. The selectable %RH
range is 26 - 90%. These buttons will not function while in FAN

the %RH goal to 60.
7.3 DEHUMIDIFY MODE: When DEHUMIDIFY MODE is selected,
the DEHUMIDIFY and RUN LED will be lit and the digital display will
show the current %RH of the room. The %RH set range is 26-
90%. When the set point is lower than the current %RH of the
room, the compressor and fan will run. When the current %RH
of the room is equal to or less than the set point, the compressor
will stop. The fan will continue to run for an additional 3 minutes.
When the set point is less than 26%, the digital display will show
CO. This indicates that the unit will run continuously
7.4 CHANGING MODES: Press the MODE button to change the
operating mode from DEHUMIDIFY to FAN or back to DEHUMIDIFY.
The corresponding LED will be lit to indicate the current operating
mode.
7.5 FAN MODE: When the FAN MODE is selected, the FAN and

11. Maintenance
11.1 Air Filter
SAKURA Dry-Boy is equipped with two (2) air filters. An aluminum/
foam pre-filter followed by a standard MERV-11 65% efficient
pleated fabric filter. These should be checked every six months.
Operating the unit with dirty filters will reduce dehumidifier
capacity and efficiency and may cause the compressor to cycle off
and on unnecessarily.
If dirty, the aluminum/foam prefilter can be vacuumed or carefully
hand washed with warm water and mild detergent then rinsed.
The pleated fabric filter can generally be vacuumed clean several
times before needing replacement.
DO NOT operate the unit without the filters or with a less effective filter.
The heat exchange coils inside the unit could become clogged and
require disassembly to clean.

12. Service
CAUTION!
Servicing SAKURA Dry-Boy with its high-pressure refrigerant
system and high-voltage circuitry presents a health hazard
which could result in death, serious bodily injury, and/or
property damage. Only qualified service people should service
this unit.
12.1 Warranty
A warranty certificate has been enclosed with this unit. Read
it before any repair is initiated.
12.2 Technical Description
SAKURA Dry-Boy uses a refrigeration system similar to an air
conditioner’s to remove heat and moisture from incoming air and
add heat to the air that is discharged (see Figure 1).
Hot, high-pressure refrigerant gas is routed from the compressor
to the condenser coil (see Figure 1). The refrigerant is cooled
and condensed by giving up its heat to the air that is about to be
discharged from the unit. The refrigerant liquid then passes through
a filter/drier and capillary tubing, which cause the refrigerant
pressure and temperature to drop. It next enters the evaporator coil
where it absorbs heat from the incoming air and evaporates
The evaporator operates in a flooded condition, which means that
all the evaporator tubes contain liquid refrigerant during normal
operation. A flooded evaporator should maintain constant pressure
and temperature across the entire coil, from inlet to outlet.
The mixture of gas and liquid refrigerant enter the accumulator
after leaving the evaporator coil. The accumulator prevents any
liquid refrigerant from reaching the compressor. The compressor
evacuates the cool refrigerant gas from the accumulator and
compresses it to a high pressure and temperature gas to repeat
the process.
13 Condensate Pump
The Condensate is automatically pumped to a remote location
when the water level in the pump’s reservoir rises to close the
float switch.
