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. 2. The blocks can be transported by means

of a forklift truck, a pallet transporter or a platform truck.

Lifting can be carried out as shown in Fig. 3–5.

EU Air Handling Unit INSTALLATION

Mounting on the floor

The floor on which the unit is placed must be flat, to

ensure problem-free operation.

Check the floor carefully to avoid distortion of the unit

and thus ensure that the doors will not be difficult to

open and close.

EUAZ-05 adjustable feet are available to allow for indi-

vidual height adjustment of the EUAZ-04 base frame.

Place the support washer (supplied) under the foot as

shown in Fig. 8. It is important to make sure that the

unit is level.

If the air handling unit includes unit sections that are

provided with drains, space must be available for a

water trap (such as the EUAZ-08) as shown in Fig. 9.

Adjustment of the lateral and longitudinal position of

the air handling unit is best carried out by means of a

roller crowbar or the like, as shown in Fig. 10 and 11.

N.B. The unit should slope 2% towards the inspection

side to allow for drainage during cleaning. Flushing

water can be collected in the EUWZ-02 drainage

water trough (accessory).

Fitting adjustable feet

The feet are fitted with even spacing along the side rails

if the number of feet is greater than 4. In the case of 4

feet, 1 foot should be fitted at each end of the side

beams.

Adjustment of set-screws:

1) Release the locking

nut (A).

2) Adjust the height

with the set-screw (B).

3) Retighten the

locking nut (A).

EU Air Handling Unit INSTALLATION

Suspended installation

Place the unit on a stand made on site as shown in the

examples in Fig. 12 and 15. Suspend the stand from

hangers. The larger units in which service personnel can

enter, must be placed on a stand with traversing or longi-

tudinal support beams. These beams must be arranged

as shown in the figures below to support the bottom

panels of the unit and thus guarantee the safety of service

personnel and other persons beneath the unit.

EUAZ-15 floor gratings must be installed in units in

which service personnel can enter. Bear in mind the need

for ease of access to enable service personnel to reach

unit components or enter the unit to perform maintenan-

ce work. The width of the unit stand must therefore

provide a min. 800 mm wide service platform in front of

the inspection doors.

Retaining flange A– max. 35 mm along the inspection

side.

Cut and remove the edge of the retaining flange ”A” at

the hinge locations.

N.B. If the unit is equipped with a EUWZ-02 drainage

trough, there are retaining flanges (A) only at the

casing corner pieces.

EU Air Handling Unit INSTALLATION

Stacked installation

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

another. Up to three size 11–32 units can be stacked on

top of one another, but only two size 40–53 units can be

stacked. In the case of units of different widths, the

inspection sides should be located straight above one

another. An angle section should be located under the

rear frame section of the upper unit (length same as the

length of the lower unit), and a piece of bar for height

adjustment should be located under the front frame

section. Fit EUAZ-10 sealing strip around the opening

of the angle section before fitting the upper unit.

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

upper units to the lower as shown in Fig. 19.

The set consists of 6 angle brackets.

Use the angle bracket as a template and secure it to the

frame section with self-tapping screws.

Connecting multi-function blocks

Sealing strip is supplied loose and must thus be fitted

before the blocks are connected together. See Fig. 20

and 21.

Jointing of blocks

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. Fit the

cover plate delivered in the recess formed by the

frame sections at the bottom.

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.

6. Use the jointing compound supplied to seal the

insides of the side and bottom joints.

N.B. Make sure that the joint bolt is located in the

bottom of the screw pocket throughout the tighte-

ning process. The cone of the joint bolt will then fit

into the cone of the screw pocket (see Fig. 22).

Connection to next EU block

Fit the self-tapping screws in the existing holes in the

frame profiles, and tighten the connector with a size

14 spanner.
