Tjernlund CS2 Crawl Space Intake Fans 8504176 User Manual download pdf

DESCRIPTION

The Tjernlund UnderAire™ Series Fresh Air Supply Fans for Crawl Spaces are designed to boost fresh outdoor air under-

neath homes and porches. Use in conjunction with Tjernlund UnderAire™ Crawl Space Exhaust Fans to remove moisture in

Crawl Spaces with too few or undersized passive vent openings, overall lengths of over 40 feet, or in “dead zones” or stag-

nant areas that are not served by existing foundation vents.

Excessive humidity levels in Crawl Spaces is the leading cause of premature rotting of support columns, joists, floors and

beam supports. Humidity can promote fungus growth and increased termite activity. Humidity may also cause plumbing

failures due to rust and corrosion. Helps dilute radon gases, treated wood off-gassing and other odors that might migrate

into living areas.

All models are equipped with a factory installed and pre-wired freeze protection thermostat which will prevent operation of

the fan below 35°F.

GENERAL INFO

GENERAL INFORMATION

Each UnderAire™ Powered Fresh Air Supply Fan is electrically factory line tested before shipment.

After opening carton, inspect thoroughly for shipment damage. Fan should rotate freely and all electrical wires and connec-

tions should be secured. If any damage is found, notify freight carrier and your distributor immediately and file a concealed

damage claim.

RECOMMENDED APPLICATION

The CS1 & CS2 Powered Fresh Air Supply Fans are designed to be used in conjunction with Tjernlund V-Series exhaust

Crawl Space Ventilators (V1, V1D, V2D). Use without exhaust fans may limit the effectiveness of these fans and cause pos-

itive pressurization of the space which can could result in property damage. For optimal performance match CFM of supply

fan to CFM of exhaust fan. For example: (1) CS1 per V1 or V1D and (1) CS2 per V2D.
