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
122 cm – 152 cm (48”-60”) apart. The
minimum cable length used to lift a standard
length (208 cm [82”] base length) is 183 cm
(72”). The minimum cable length to lift
energy recovery units (295 cm [116”] base
length) is 244 cm (96”). The shackles used
to connect the cables to the lifting points in
the base must be 1.3 cm (1/2”) 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.
