Rail Mounting / Layout
• Rails designed to handle the weight of the ERV should be positioned as shown on the diagram (rails by
others).
• Make sure that rail positioning does not interfere with the supply air discharge opening or the exhaust air
intake opening on the ERV unit. Avoid area dimensioned “B” below.
• Rails should extend beyond the unit a minimum of 12 inches on each side.
• Set unit on rails.
Outdoor Air Weatherhood
Outdoor air weatherhood will be factory
mounted.
Exhaust Weatherhood
The exhaust weatherhood is shipped
separately as a kit with its own
instructions.
Dampers
Backdraft dampers are always
included as an integral part of the
exhaust hood assemblies. Motorized
outdoor air and exhaust air dampers
are optional and are factory mounted
(and wired) at the intake.
