6 . Remove all top paneling and the intermediates . Use the
supply fan assembly base frame to lift the whole section .
Hook points have been added to the design . Fan sizes
40" and larger will use AVKs and eyebolts . Use long
enough chains to avoid exerting pressure on the fan or
the motor from the side . Lift the fan section slowly until
it is supported. Remove the painted steel plates (flat
and right angle) connecting the section to compressor/
condenser section and coil/access section . Balance the
tension in the lifting chains to pull the section back five
inches to disengage the splice collar frame from the coil
section . Lift the fan section carefully and slowly away
from the unit (See Figure
7 . Once the supply fan section is removed, the compressor/
condenser section can be accessed from the top .
Remove the side access panels on both sides of the
section (Right or Left hand units) . Locate and remove
the Victaulic couplings of the water pipes (15/16"
wrench or socket) . Relieve the Nitrogen charge in each
refrigerant circuit before cutting any refrigerant line . Cut
Refrigerant lines (liquid and suction) at locations that will
be accessible to brazing during unit reassembly . See
(Figure 9) for suggested cut area . Cover the refrigerant
pipes on both sides of the cut to avoid contamination .
NOTE: The model shown has four circuits . Number of circuits
ranges from two on small units to eight on large ones .
There may be more lines to cut on large units . Mark
circuits if necessary, to avoid confusion .
8 . Remove painted flat steel plates (from the side)
connecting this section with the coil sections (same
plates connecting fan, coil and condenser/compressor
sections) . Remove the double galvanized steel plates
connecting the base sections together to split the coil/
access section from the compressor/condenser section
with a 9/16" wrench or socket . Splitting the two sections
apart will expose the other four lifting brackets . Use
the four base lifting brackets on each section for lifting .
Use spreader bars to keep the lifting chains away from
the section frame to prevent any damage to the unit
structure . The center of gravity is higher than the base
level . Handle the section carefully to avoid tilting .
9 . The base lifting lugs must be used to lift the coil section
(See Figure 10) . Spreader bars are needed to prevent
the chains from exerting lateral pressure on the coil
frame .
Coil section is heavier than the fan section . Lifting chains used
on this section must have the proper safety ratings .

The center of gravity is higher than the base level .
Coil section is the tallest and has many delicate parts that can
be damaged easily as a result of falling or bumping into walls
or other equipment . Any damage to the section may require a
coil replacement . Handle the coil section slowly and carefully
(restrain as required) to avoid tilting .
