Location Selection
The HRV must be located in a heated space where it will be
possible to conveniently service the unit. Typically the HRV
would be located in the mechanical room or an area close to the
outside wall where the weather hoods will be mounted. If a
basement area is not convenient or does not exist, a utility or
laundry room may be used.
Attic installations are not normally recommended due to:
A) the complexity of work to install
B) freezing conditions in the attic
C) difficulty of access for servicing
Suspending the HRV
The hanging straps should be attached to the unit at the top end
corners (mounting screws are already located on the HRV case).
Securely fasten the other end of the straps to the floor joists with
wide head nails (not supplied), making sure the UNIT IS
LEVEL. The straps are designed to reduce the possibility of
noise, resonance or harmonics; therefore using the full length of
the strap between the HRV and the floor joists is recommended.

Unit must be installed level to ensure proper
condensate drainage. Due to the broad range of

consideration must be given for the possibility
of condensation forming on the unit or
connecting ducting. Objects below the
installation may be exposed to condensate.
