How to Hang it
The mounting diagram shows the hanger mounts on the ends of the outside frame. However, the frames either have a latch or a door on them. There are 4 sets of holes already drilled in the top of the box. Are they strong enough to hold the unit?

Can I install this unit 20 feet away from an outside wall?
Thank you for your question on the model HRV90HS fresh air systems. The HRV90HS should be mounted as close as possible to the outside wall. Please contact the Technical Service Department at 800-637-1453 for assistance.

How do you turn on unit with furnace control?
Installed HRV90 using connection to the furnace. Now my furnace fan operates whenever HRV is turned on (HRV master - furnace slave). Would like to wire the unit so that the HRV turns on only when the furnace is actuated by it's thermostat (furnace master - HRV slave). Can someone help me with this wiring?

Do any of your models have a summer bypass option?
I have a home with an insulated hollow core concrete slab on grade. The slab distributes/stores warmed air to each room via floor vents. Two plenums feed heated air into the system. One is a furnace and the other is a fan that pushes solar heated air from our solarium. We have 10" thick insulated walls and 14" inch thick insulated ceilings. The house is tight. Our problem is over warming in the summer. I have read there are HRV units that provide a bypass to the exchanger which would allow us to cool the pad with cool summer night air. We built the house in 1983 and love the solar boost we get during most of the year in the northwest. The pad keeps the temperature flux down but when it gets too warm it becomes a challenge to cool. We don't want a heat pump. Thank you!
