Draw-Out Device Installation 

Removing the Device 

Use  the  following  procedure  to  remove  the  draw-out 
device from the substructure. 

CAUTION:

  The  device  must  be  OFF  before  it  is  dis-

connected and removed. 

ATTENTION:

  Le  mécanisme  doit  être  à  OFF  avant  qu’il 

ne soit débroché et déposé. 

Engage the 1/2 - inch square end of the racking shaft 
with  the  supplied  wrench,  catalog  number  TDORT, 
as  illustrated  in  Figure  7,  and  rotate  the  shaft 
counter-clockwise  to  withdraw  the  device  to  the 
TEST or DISCONNECTED position. The compartment 
position indicator is shown in Figure 8.
Pull the substructure rails out as far as possible until 
they  drop  into  the  horizontal  locked  position,  as 
illustrated in Figure 9.
From  the  DISCONNECTED  position, pull  the  device 
out  on  the  rails  until  the  front  rollers  fall  into  the 
detent, as illustrated in Figure 6.
The device can now be rotated about the front roller 
by  pulling  forward,  as  illustrated  in  Figure  10,  for 
inspection  of  the  rear  of  the  device,  or  it  can  be 
completely removed after attaching the Lifting Bar, 
as illustrated in Figures 4 and 5.
