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.
