The design and size of the weatherhoods or louvers chosen by the installer must allow for adequate free area. Water and snow penetration of the system is minimized when the airflow does not exceed 750 FPM (3.81m/s) free area velocity. Ducting from the Weatherhoods Galvanized sheet metal ducting with sufficient cross section with an integral single piece vapor barrier should be used to connect the HRV to the weatherhoods. All ducting must meet ULC Class 1 Fire Rating. A minimum R value of insulat

It is easily removed for cleaning or service. MOTORS AND BLOWERS: Each air stream has one centr

ft, and the LT-20 of a home up to 4000 sq. ft. (On a smaller home, they can be operated at lower speed, reserving excess capacity for temporary increases in humidity or other contaminants.) They are technically advanced controlled mechanical ventilation systems designed to meet the requirements of modern, tightly built and highly insulated homes. They provide a consistent supply of fresh air while lowering heating costs during the winter by transferring heat from the exhaust air to the fresh air

MOTORS AND BLOWERS Each air stream has an independent motorized impeller. 3 speedoperation 120VAC FILTERS Washable air filters in exhaust and supply air streams.
