1 Intended Application
The intended application for the Vehere is as a pool &
spa area humidity sensing controller applied either as a
free-standing device directly in the pool area or operated
remotely to provide dehumidified air to the pool or spa
area using optional ducting and remotely mounting the
humidity controller. The Vehere high efficiency dehumidifier
utilizes refrigeration to cool an incoming air stream below
its dewpoint as it passes through an evaporator coil. This
cooling results in the removal of moisture (latent heat).
The cooled and dried air is used to pre-cool the incoming
air stream resulting in up to a 200 percent increase in
overall efficiency.

*ASHRAE Recommended Conditions
Read these installation, operation and service
instructions carefully before installing and using this
unit. Proper adherence to these instructions is essential
to obtain maximum benefit from your Vehere pool & spa
humidity controller.
• If used near a pool or spa, be certain there is NO
chance the unit could roll into the water or be
splashed and that it is plugged into a GROUND FAULT
INTERRUPTER.
• DO NOT use the Vehere as a bench or table.
• Avoid discharging the exhaust directly at people or
pets.
