the following points:
The Vehere will require a single 12” round or equivalent
dedicated return from the pool room. The Vehere supply can
be dedicated or tapped into a forced air system supply. A
check damper should be used at the connections.
The warm/dry supply air should be washed over the windows
at multiple drops for best results. Grills and diffusers or duct
ends must not excessively restrict airflow.
Round flex duct can be purchased by ordering the following
part numbers from the factory:

4020177 8” Flex Duct 8” x 25’
4022126 10” Flex Duct 10” x 25’
4024750 12” Flex Duct 12” x 25’
4 Operation
4.1 Humidity Sensor/Control
The control is an adjustable switch that closes when the
relative humidity of the air it senses rises to the dial set point.
It opens when the RH drops 4 to 6% below the set point. (See
Fig. 9)
4.2 Humidity Control Adjustment
The dehumidifier will run until the desired relative humidity
(RH) matches the control dial setting.
The humidity controller has been designed for simplicity
of use. It is marked “Low”, “Normal” and “High.” These
operational settings represent the amount of humidity in
the air. Setting the control to the “Low” setting will result
in a lower relative humidity than the “High” setting. We
recommend setting the controller at the “Normal” setting and
then adjusting as you see fit, moving the controller toward
“Low” to lower the humidity and toward “High” to increase
the level of humidity in your pool or spa area.
Approximate Humidity Levels Per Setting
“Low”
35% to 45% Relative Humidity

“Normal” 45% to 55% Relative Humidity (Recommended)
“High”
55% to 65% Relative Humidity
A quality humidity meter is recommended to accurately
monitor humidity levels. For a quote on a quality humidity
meter, contact customer service at 1-800-533-7533.
4.3 Fan Switch
Turning the fan switch 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 fresh air ventilation.
(See Fig. 10)
4.4 Automatic Defrost Control
When the Vehere is used in a cool area, frost may form on
the cooling coil as it dehumidifies. When frost forms, our
automatic defrost thermostat will periodically turn off the
compressor while allowing the blower to run. The blower
draws air through the cooling coil and melts the frost.
The defrost cycle is automatic and designed for optimum
performance above 50°F.
4.5 Automatic Low Pressure Control
If the low side refrigerant pressure drops to 35 PSIG, the
low pressure control opens and shuts off the compressor
and blower. It is an automatic reset that will close when the
pressure rises to 60 PSIG. This feature prevents damage to
the compressor. It may also open if the unit is used in a cool
area (below 50°F) or stored below 40°F and then started.
Under these conditions, the unit will restart within several
minutes.
