INSTALLATION - CONT.
INSTALL HOODS
Intake and exhaust hoods for these models are shipped separately from the unit. To install hoods, see Figure 7. A quick connect for the damper motor
is provided to connect to the main body of the unit for hoods equipped with motorized dampers. Make sure that all the screws are secured to maintain
proper support and to keep the seals watertight.

PLACING THE UNIT
All ERV 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 Sys-
temair 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 difficult 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.
