Lifting the Unit
The RQ Series units must be lifted using the
lifting points in the side base rails. A
spreader bar must be used to prevent the
lifting straps from damaging the unit. The
connection points on the spreader bar must
be 48”-60” apart. The minimum cable
length used to lift a standard length (82”
base length) is 72”. The minimum cable
length to lift energy recovery units (116”
base length) is 96”. The shackles used to
connect the cables to the lifting points in the
base should be ½” nominal size.
The rigging must be adjusted to lift the unit
level. Lifting the unit off-balance may cause
severe damage.
It is recommended to lift the unit with the
outside air hood in the downward shipping position. However, the unit may be lifted
with the outside air hood in the open
position.
Before lifting unit, be sure that all shipping
material has been removed from unit. Secure
hooks and cables at all lifting points
provided on the unit.
Hoist unit to a point directly above the curb
and duct openings. Be sure that the gasket
material has been applied to curb.
Carefully lower and align the unit with
utility and duct openings. Lower the unit
until the unit skirt fits around the curb. Some
units are designed to overhang the curb.
Take care that any recessed base rails fit
around the curb. Make sure the unit is
properly seated on the curb and is level.
