instructions. Failure to heed them can result in injury or
material property damage.
1. Intended Application
The SaniDry CSB is intended for installation in crawl spaces or
basements that experience short or long-term high humidity
conditions; however, the attractively designed unit can be placed in
almost any residential setting where dehumidification is desired. Use
in non-residential applications and pool areas will void warranty.
The SaniDry CSB is designed to operate in temperatures between
56° and 95°F. Temperatures outside of these ranges may affect
dehumidifier performance.
In order to efficiently control the humidity levels, the area in which
the dehumidifier is to be placed must be free of water intrusion or
excessive fresh (outside) air infiltration. Before installing the SaniDry
CSB, water intrusion and air infiltration problems should be addressed.

4. Unit Assembly
4.1 Installing Feet (Optional)
Included with your SaniDry
CSB are four leveling feet. It is
important to level the unit for
proper draining. (See section
5.1.4, Figure 6)
Installing Leveling Feet
See Figures 2 and 2a for installing leveling feet.
1. Lay down a protective pad (pillow, blanket, etc.).
2. Carefully turn unit onto side opposite filter opening and drain
port.
3. Align leveling foot shaft with one of the four threaded hole
locations as shown in Figure 2.
4. Screw each leveling foot in ten revolutions.
5. Carefully bring unit to upright position.
6. Level unit for proper drainage as described in section 5.1.4
(Figure 6) of this manual.
7. Wait 10 minutes before operating.
CAUTION!
Note: Operating the unit immediately after bringing it to an upright
position can possibly damage the compressor. A short amount
of time is needed to allow the oil to return to it’s reservoir for
lubrication.
4.2 Drain Hose
Take drain hose off of drain port. With scissors, cut one inch off of
hose end to eliminate dented area. Place drain hose end on drain
port until fully seated. Refer to Section 5.1.4 regarding proper
drainage.
5. Installation
5.1 Location
The SaniDry CSB can be installed in a variety oocations to meet
the owner’s needs, but should beinstalled directly in the area to be
dehumidified. Other considerations include:
1. Providing access to a 115 VAC power outlet (10' power cord
is provided).
2. Locating near a oor or other suitable drain (8' drain hose
included).
3. Do not install the SaniDry CSB with the intake or exhaust of
the unit within 1' of a wall or other obstruction. Do not place
the unit where curtains or debris can be drawn onto the
intake and restrict airow. Do not operate in standing water
or place the unit near open water. Refer to Figure 5.
4. The SaniDry CSB drains via a gravity system. A level
indicator has been included near the intake of the unit.
To ensure the unit will drain properly, the unit should be
positioned so the level bubble appears in the non-shaded
area of the level indicator as shown. Refer to Figure 6. If
the unit is placed on an unlevel surface, adjust leveling feet
using a crescent wrench or 7/16" open wrench. Move handle
end of wrench from left to right to lower one foot. Adjust all
four feet underneath the unit until bubble in the level dial is
in the correct position. Failure to level the unit may result
in leakage or improper drainage. See Section 4.2 regarding
drain hose installation.

5.2 Electrical Requirements
The SaniDry CSB plugs into a common grounded outlet on a 15-
Amp circuit. While operating, it draws less than 7 amps @ 80°F,
60% RH and less than 6 amps @ 75°F, 50% RH. Use of a ground
fault circuit interrupter (GFCI) protected circuit is recommended.
The unit should not be used in areas prone to ooding.
5.3 Condensate (Water) Removal
The SaniDry CSB drains via a gravity system - it is not able to
push condensate (water) uphill. The drain hose must run at or
downhill toward the drain location. Be sure the hose is not kinked
or otherwise restricted so that water can pass through it. Improper
hose installation may result in water leakage.
To increase the efficiency of the unit, position the hose to create a
“trap” as shown in Figure 8. By creating a trap, it will hold a small
amount of water. Position the trap on the hose approximately 12" to
20" away from the unit. Check hose regularly to ensure it is clear and
water is draining properly.
If oor drain is not easily accessible, a condensate pump kit with a
20' hose is available. Refer to page 5 for ordering accessories.
6. Operation
6.1 Humidity Control Adjustment
The humidity control is an adjustable switch that turns the
dehumidifier on and off. It turns on when the relative humidity of
the air in which it is located rises to the dial set point. It turns off
when the RH drops 5% below the set point.
Approximate Humidity Levels Per Setting
“Dry” 35% to 45% Relative Humidity
“Normal” 45% to 55% Relative Humidity
(Recommended for most applications)
“Humid” 55% to 65% Relative Humidity
The dehumidifier will run continuously until the relative humidity
(RH) is reduced to the humidity control dial setting. There is no
benefit to setting the humidity control to “dry” in rooms under 65°;
doing so will result in long periods of ineffective dehumidifier run
time.
Once the dial has been set to the desired level of humidity control,
the SaniDry CSB will maintain the same percentage of relative
humidity regardless of room temperature.
To turn the unit off, position the humidity dial to the far left and set
fan control to “auto.”
6.2 Defrost Cycle
An automatic defrost thermostat is attached to the refrigerant
tubes inside the unit. It will automatically shut the compressor
off if excessive frost forms on the evaporator coil. The blower
will continue to run, causing air to ow through the evaporator
coil and melt the ice. When the ice has melted, the evaporator
temperature will rise and the thermostat will automatically restart
the compressor. During this process, cool air may be coming out of
the unit.
6.3 Electrical Requirements
Turning the fan switch “FAN ON” will cause the unit’s internal
blower to run continuously, whether the unit is dehumidifying or
not. This function is desirable if the unit is used for air circulation
or ltration. Turning the fan switch to “FAN
AUTO” will cause the unit’s internal blower to
run only while the unit is dehumidifying.

7. Maintenance
CAUTION!
NOTE: Do not operate the unit without the proper filter or with
a less effective filter. The heat exchange coils inside the unit
could become clogged, resulting in a loss of effectiveness
and/or efficiency and may require disassembly to clean.
7.1 Air Filter
The SaniDry CSB ships with a standard MERV-11 65% 1"
pleated fabric filter and a 1/4" aluminum framed pre-filter
installed. Operating the unit with a dirty or obstructed filter will
reduce dehumidifier capacity and efficiency and may cause the
compressor to cycle on and off unnecessarily.
7.2 Cleaning & Replacement
Check filters every six months. Clean and/or replace when filters are
visibly dirty. See cleaning instructions below. For replacement filters
call your local Basement Systems dealer.
The 1/4" washable pre-filter
should not to be discarded.
Inspect the pre-filter for debris,
dirt, or other obstructions at
the same time the 1" pleated
fabric filter is checked. Wash the
1/4" pre-filter every time the 1"
pleated fabric filter is replaced. To
clean the 1/4" pre-filter, remove
filter from the unit, rinse the 1/4"
pre-filter in water with the water
owing through the aluminum
support mesh side. Refer to
Figure 11. Allow the filter to dry
completely before reinstalling.
Reinstall the filters per the
instructions below or on the tag
located on the 1/4" pre-filter.
CAUTION!
NOTE: Failure to follow filter handling instructions may result
in improper function of the dehumidifier and cause premature
filter wear.
7.3 Remove Filters
1. Gently remove the 1/4" pre-lter by pulling on the tab
attached to the filter.
2. Gently remove the 1" pleated fabric lter by pulling it out
of the unit.
7.4 Installing Filters
1. Gently slide 1" pleated lter into lter slot. Do not force.
If resistance is felt, check alignment for obstructions or
debris inside the filter housing.
2. Gently slide 1/4" pre-lter to left of 1" pleated lter.
Do not force. If resistance is felt, check alignment for
obstructions or debris inside the filter housing.
8. Service
WARNING!
Servicing the SaniDry CSB with its high pressure refrigerant
system and high voltage circuitrypresents a health hazard which
could result in death, serious bodily injury, and/or property
damage. Only qualified service people should service this unit.
8.1 Technical Description

SANIDRY CSB INSTALLER'S AND OWNER'S MANUAL
6SaniDry CSB Installer’s & Owner’s Manual
gas is routed from the compressor to the condenser coil. The
refrigerant is cooled and condensed by giving up its heat to the
air that is discharged from the dehumidifier. The refrigerant liquid
then passes through 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 ooded condition, which means
that all the evaporator tubes contain liquid refrigerant during
normal operation. A ooded 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.
