Method 1

Pull the sections against each other, using the pull

ropes attached to the lifting bars. Pull evenly on both

sides of the AHU.

5.2. Connecting Casings of Equal Width

and Height

To connect the AHU sections use one of the follo-

wing methods. The method depends on the AHU

construction.

Method 1

This method applies for sections that end in joint

mullions:

• Check that the four corners are attached.

ces

- Ensure that the sealing tape supplied is fixed to

one of the two sections, before moving the sections

against each other.

• Then place the anti-vibration mats where the next

casing section will be positioned and then place

this section.

• Before placing the sections against each other, fix

the sealing tape supplied between the sections. This

should be done in four places, and the sealing tape

should overlap at the corners See Figs 17 and 21.

The labels which show the matching surfaces are for

making easy the matching of unit surfaces correctly

during assembly of AHU. Same numbers should be

side by side.

NOTE: Attach the sealing tape supplied to only one

of the two assembled sections.

- Place the sections as close together as possible.

Ensure that both sections can still be moved. Insert

a lifting bar into both sections, so that they can be

pulled closer towards each other.

There are two methods for pulling the sections to-

wards each other:

Method 2

Insert a bar with threaded ends through both lifting

bar holes. Screw a nut onto the threaded ends of the

bar and tighten it. Tighten it evenly on both sides of

the AHU.

NOTE: Before connecting the sections, they should be

horizontally and vertically aligned, using infill plates. If

the floor is not completely level, first place the casing

section that will be on the highest part of the floor.
