FIBERGLASS DUCTWORK INSTALLATION
Power Connection Requirements:
This device is designed to operate using
a 24 VAC, 40Va transformer. Transformers supplied with a straight cooling
or HVAC system may be used to power the device but must be verified it’s
capable of handling the additional device load before installation. If the system
transformer is not capable of handing the extra load, a separate 24 VAC, 40Va
transformer MUST be used. Do not connect the device to any power source
with a voltage less than 22 VAC and a maximum of 32 VAC. Doing so will cause
damage to the device.
