9. MAKE AIR DUCT CONNECTIONS
DISCHARGE CONNECTIONS
Connect the flanged discharge openings to the supply
duct utilizing a canvas connection to prevent vibra¬
tion. It is important that this connection be properh
fabricated to prevent high friction losses and air
noise.
RETURN CONNECTIONS
The return and outside air connections should be
brought to the filter rack through a canvas connectio
to prevent transmission of unit vibration.
When a duct blocks off the access panel provide a
slip joint in the duct work so that it may be removed
for service purposes.
OUTSIDE AIR INLET CONNECTIONS
Outside air inlet connections should be tapped into tl
return air duct work. A damper must be provided ii
the outside air duct to permit the control of the out¬
side air volume.
