RIGGING THE ENCLOSURE

Where
overhead room and/or clearance in front of the drive en-
closure is insufficient to allow the drive to be safely removed from
the enclosure, the entire enclosure may have to be removed from
the chiller.
The dimensions and weights specified must be taken into consid-
eration when removing the enclosure. For 19XRV chillers, the to-
tal weight for Frames 6 and 7, including drive weight and enclo-
sure, is 720 lb. The 23XRV chiller enclosure, including all compo-
nents, weighs 975 lb. All lifting equipment and lifting components
(hooks, bolts, lifts, slings, chains, etc.) must be properly sized and
rated to safely lift and hold the weight of the enclosure and drive
while removing. See Fig. 24 and Fig. 25.
