EU Air Handling Unit INSTALLATION

Delivery

The EUGA unit is delivered in accordance with one of

the following alternatives:

■As one delivery unit, i.e. factory-assembled in one

multi-function block

■As one delivery unit, i.e. factory-assembled unit

mounted on a base frame.

■Several multi-function blocks which are connected to

form one unit on site.

Lifting and transport

The weight of each multi-function block is specified on

the rating plate. Each block is provided with packaging

as shown in Fig. 3. The blocks can be transported by

means of a forklift truck, a pallet transporter or a plat-

form truck. Lifting can be carried out as shown in Fig.

4–10.

Place the unit on a flat surface. Back off the screws in the

corner sections. Hook the lifting lugs onto the screws

and tighten the screws to a torque of 22–24 Nm.

Mounting on the floor

The floor on which the unit is mounted must be level, to

ensure its problem-free function. Carefully check the

floor to ensure that distortion and problems in opening

and closing the doors are not built into the unit.

Base frame EUAZ-04 can be supplied with adjustable

feet EUAZ-05 for individual height adjustment. These

are available for sizes 11-53. Non-adjustable feet are

available for larger sizes. The support washer supplied is

placed under the foot; see Fig. 12. It is important to

ensure that the unit is positioned horizontally.

Space for a water trap (e.g. EUAZ-08) must be provid-

ed for air handling units which contain functional com-

ponents with a drainage facility. See Fig. 14.

Lateral and longitudinal position adjustment is most eas-

ily performed with a roller crowbar or similar. See Figs.

15 and 16.

Larger and heavier units can be raised by using a

hand-operated form loader on both short sides to avoid

damage to the underside of the unit. See Fig. 17.

Installation of adjustable feet

The feet should be installed at regular intervals along the

side rails, if they are more than 4 in number. Where 4

feet are required, one foot should be installed at each end

of the side rails.

Adjustment of

set-screws:

1) Release the

locking nut (A).

2) Adjust the height

with the set-screw

(B).

3) Lock the locking

nut (A).

Suspended mounting from the ceiling

Place the unit on a frame constructed on-site. See the

examples in Figs. 18 to 23. Suspend the frame from pen-

dant hangers.

The frame must also be executed so that so that the

base panels have either transverse or longitudinal support

rails on the underside.

Important!

The hangers must be positioned so that they do not

obstruct the inspection hatches. A frame of the kind

shown in Fig. 18 permits easy adjustment of the hangers.

Stacked or angle installation

Units of the same width can be stacked on top of one

another. Up to three size 11–32 units, but only two size

40–85 units can be stacked on top of one another. In the

case of units of different width, the inspection doors

should be positioned directly above one another. An

angle iron should be positioned under the rear frame sec-

tion of the upper unit (same length as of the lower unit)

and a piece of bar for height compensation should be

positioned under the front frame section. Fit EUAZ-10

sealing strip around the opening of the angle section

before fitting the upper unit.

(upward outlet)

The EUAZ-16 jointing piece set is used for securing the

upper units to the lower as shown in Fig. 25. The set

consists of 6 angle brackets. Use the angle bracket as a

template and secure it to the frame section with self-tap-

ping screws. (Delning max. 1,5 m)

Mounting on wall brackets

Vertical installation

The following surface is necessary for vertical installa-

tion:

Flat floor or a frame made of e.g. 50 x 50 x 5 mm angle

iron, with the outside dimensions adapted to those of the

unit, A x B mm.

N.B. Vertical installation applies only to sizes 11–32 of

standard design.

Mounting on a stand

Note.

Do not locate the stand so that the inlet or outlet or the

inspection doors are obstructed.

Use straps or mountings such as perforated straps for

securing the unit to a wall.

Connecting one or several multi-function

blocks

Sealing strip is supplied loose and must thus be fitted before

the blocks are connected together. See Fig. 30 and 31.

Fig. 31 15 x 5

Jointing of blocks, sizes 11–53

Internal bolted joints at the corners of the frame are used

for jointing the blocks to one another. Access to the

inside of the casing can be gained either by opening an

inspection door or by removing a wall panel. Withdraw a

unit section if it is in the way.

1. Fit the sealing strips supplied to the frame of one of

the blocks.

2. Push the blocks towards one another, making sure that

they are well lined up with one another.

3. Fit the joint bolts into the corner brackets on the

inside of the frame and make sure that they are firmly

in position.

4. Use a 14 mm spanner for the joint bolts to pull the

blocks together.

5. Tighten all four joint bolts alternately, compressing

the seal to 1–2 mm.

Jointing of blocks, sizes 60–84

Internal bolted joints at the bolt lugs fitted along the

frame are used for jointing the blocks to one another.

Access to the inside of the casing can be gained either by

opening an inspection door or by removing a wall panel.

Some of the unit sections, such as the filter section, may

be dismantled for better access.

1. Fit the sealing strips supplied to the frame of one of

the blocks.

2. Push the blocks towards one another, making sure that

they are well lined up with one another.

3. Fit the joint bolts into the corner brackets on the

inside of the frame and make sure that they are firmly

in position.

4. Tighten the nuts alternately, compressing the seal to

1–2 mm.
