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.
