PLACING THE UNIT

All Topvex RT-EC series units are provided with integral rigging

holes. Units must be lifted via these rigging provisions using a

spreader system (provided by others) which protects the upper

exterior of the Systemair Energy Recovery Unit during lifting.

Before placing the unit into position, ensure the supply and exhaust

duct openings are free from obstruction. The neoprene insulation

might have been left intact at the factory to kept these openings

closed to prevent any unwanted items to enter the unit (see Figure

6). It will be easy to clear this obstruction from the exhaust air

duct opening even after the unit is placed into position, however it

will be more difcult to do so for the supply air.

After placing the unit atop the mounting supports or roof curb,

check to insure that the unit is level.
