Risk of property damage.
This unit is not a convenience air conditioner - it is a process dehumidifier that is
closely sized to the expected load. Any errors in installation, balancing, or startup will be
obvious in operation.
Improper flows may result in damage to the equipment, unexpected condensation in the
building leading to damage, or monetary losses due to failure to reclaim energy.
The flows must be measured and set within 10% of the stated values.
