Fantech VHR704R Installation Manual - Vhr 704R
3
Compact top port design HRV with easy-mount wall bracket.
Brings a continuous supply of fresh air into a home while
exhausting an equal amount of contaminated air. HRVs use
what is called a “sensible” heat recovery core. This special
core transfers heat from the exhaust air stream to the
incoming air stream. Fresh incoming air is tempered by the
heat that is transferred from the outgoing air to save on
energy costs. The VHR 704R is equipped with automatic
defrost mechanisms so even if you live in the coldest cli-
mates you can use your HRV all year long.

DEFROST A preset defrost sequence is activated at an outdoor
temperature of 23° F (-5°C) and lower. During the defrost
sequence, the fresh air is interrupted momentarily and indoor
air is allowed to recirculate in the exchanger to maximize the
effectiveness of the defrost strategy. The unit then returns to
normal operation until the next defrost sequence.
