4. Location platform
Check that the DFLEX platform is properly planned and has the minimum dimensions
indicated.
Refer to dimensions A and B in the DFLEX external dimensions diagram.
If the model incorporates extra batteries, space will be required for the condensate drain,
in which case the height 2H is determined by the expression.:

Where P is the total fan pressure
Provide metric and mechanical tools such as:
- Spanners and socket set 13/17/19/24/32 mm.
- Clamps. >300mm<
- Tape measure. >5m<
- Sealant applicator gun for 300mL cartridges.
- 3-6 mm Allen keys.

5. Arrangement of modules
5.1 Module 9 arrangement (optional)
If module 9 is not available, proceed directly to point 5.2, following the steps in this
section (5.1).
Implementation steps:
- Locate the module labelled -9- (or module -3- if -9- is not available).
- Position it 100mm from the right and front edge of the platform, aligned with the
longitudinal axis of the platform.
- Remove the transport guards.

5.2 Module 3 arrangement
Implementation steps:
- Locate module -3-
- Remove the transport guards and unload it at > 600mm in line with module -3-,
and match the section identified as S3-9.
- Inside is the box with gaskets and screws for later assembly according to
instructions.
- Then apply the self-adhesive sealing gasket to the contact edge between
sections, on module -3- face only.
S3-9

- To avoid the lifting cables deforming the module, it is important to comply with
the dimensions of the following figure:
- In order for the minimum angle to be 70º, the height of the crane must be at least
3025mm. This applies to all lower modules (1, 2, 3 and 9).
- Once the module, -3-, has been placed on the platform, move it longitudinally
until it contacts the adjacent section, module -9-.
- Fit connecting bolts into the base rail joint loosely, without giving the final
tightening.

5.3 Module 2 arrangement
Implementation steps:
- Locate module -2-
- Remove the transport guards and unload it at > 600mm in line with module -3-,
and match the section identified as S2-3.
- Then apply the self-adhesive sealing gasket to the contact edge between
sections, on module -3- face only.
S2-3

- Once module -2- is on the platform, move it longitudinally until it contacts the
adjacent section, module -3-.
- When the sections are in place as shown below, apply the self-adhesive sealing
gasket, in this case in section S4-2 (Vertical union between modules -2- and -4-).
- Finally, fit connecting bolts into the base rail joint loosely, without giving the
final tightening.

5.4 Module 4 arrangement
Implementation steps:
- Locate the module labelled -4-
- Remove the transport guards.
- Suspend it using the eyebolts at the top, installed for this purpose.
- Make sure that the eyebolts have the following orientation as viewed from the
front and the side of the module -4- respectively:
- The minimum angle of the ropes with the eyebolts must be 45 °, therefore the
minimum height of the crane must be 175 mm.
- Place module -4- on module -2-, with section S4-2 perfectly aligned.

- Without removing the slings, place the fastening screws in section S4-2 to avoid
unwanted movement. IMPORTANT: The bolts should not be used to pull the unit
together, they are for fixing only. Make sure that the modules -2- and -4- are
perfectly aligned and there is no gap between the two. Do not apply final
tightening yet.

5.5 Module 1 arrangement
Implementation steps:
- Now locate and unpack module -1-. Apply the self-adhesive sealing gasket to the
contact edge of sections S1-4 and S1-2 on the face of the module only.
- Unload the module at> 100 mm from the previous module, centered and aligned
with the longitudinal axis by matching the section identified as S1-2.
- Once the module, -1-, has been placed on the platform, move it longitudinally
until it makes contact with the adjacent section.
- When the module -1 is in position, place the screws of the connecting sections
between the modules -1-, -2- and -4-. REMEMBER: The bolts should not exert
traction. Make sure that the modules -1-, -2- and -4- are perfectly aligned and
there is no gap between the two. Do not apply final tightening yet.

5.6 Module 5 arrangement
Once the previous sections are complete, as shown, find the MOD 5 (corresponding
reactivation heater) and its assembly accessories, such as sealants and screws,
included in a labelled blister pack.
Read the assembly instructions corresponding to the selected reactivation heater type:
- Steam unit. See section 5.6.1
- Electric heater unit. See section 5.6.2
- Gas burner. See section 5.6.3

To begin, removethe cover of theMOD 4 (basic unit) that gives access tothe reactivation
plenum.

Find the putty for the joints in the accessories pack, shape and apply it as follows:
•Take a portion of about 4 cm³ and knead it cylindrically into a string shape
of 7-9 mm in diameter.
•Apply the ‘string’in the rectangular flange connection of both modules,
and specifically in section S5-4 corresponding to the MOD4 (basic unit).
•Repeat this operation until the flange around the entire outer perimeter is
complete. Be careful not to cover the screw holes.
•This process is the same for all three types of reactivation heaters.
