2.4. Offloading and Hoisting

Depending on the dimensions of the AHU and the

situation on site, the AHUs are supplied in previously

agreed transport sections.

Before proceeding with the transport and installation

of the casing sections, always consult the applicable

dimensional drawing that give the dimensions and

weights of the sections, as well as the installation

sequence.

The weight is given on each transport section (See

Appendix 1). Each transport section is equipped with

a subframe with four lifting points.These points are

marked by the label shown below.

For offloading as well as hoisting lifting cables can be

attached to the lifting bars. Evenly positioned spacer

bars should be used between the lifting cables to

prevent damage to the top of the unit and ensure

that no excess pressure is applied to the side panels.

For hoisting please ensure that the weight is evenly

distributed.

The AHU should not be lifted or moved under the

cross beams. This is indicated by the label below.

1 - SAFETY CONSIDERATIONS

1.1 - General

The 39HQ air handling units (AHUs) has been designed

and manufactured in accordance with the CE machine

directive EN292. In order to guarantee safe operation and

use of the unit, please carefully read and observe the

instructions in this document and pay special attention to

the warnings that apply to this unit. Any modifications in

the design and/or installation of the AHU that are carried

out without discussion with Alarko Carrier and

without advance written agreement will result in the loss of

the right to any warranty claims and any claim for injury to

personnel as a result of these modifications.

Maintenance procedures may only be carried out by

qualified personnel.

Heating and cooling elements are manufactured and

supplied in accordance with guidelines of the Pressure

Equipment Directive (PED).

1.2 - Applications

The AHU is designed for the movement and conditioning

of air, unless otherwise agreed during the design stage.

1.3 - Instruction types

The following warning pictograms and labels with text are

used.

Lifting point

This pictogram shows where the AHU must be lifted and is

positioned on the support beam.

Lifting prohibited

This pictogram shows that no horizontal transport devices

must be placed under this frame section, such as pallet

lifters or the forks of fork lift trucks. It is also forbidden to

place lifting devices for transport and storage under this

frame element.

Earthing

This pictogram indicates where the AHU must be earthed

and is on one of the support beams beneath the casing in

the fan section.

- The electrical components in the AHU must be earthed,

except for components with double insulation and/or

components with a supply voltage below 50 V.

- The electrical components must be installed in accordance

with national and local regulations.

Rotating parts

This pictogram indicates that there are rotating parts behind

this access cover, door or panel which may cause injury. The

components that include rotating parts are the fan and heat

recovery wheel. If there are special customer-specific

components behind doors, access covers or panels that

include rotating parts and pose a potential risk, this is also

indicated by this pictogram.

Hot surfaces

This pictogram indicates that there are components behind

this access cover, door or panel that can cause serious burns

when touched.

The components that may have hot surfaces are the steam

humidifier, steam heater and the electric heater. If there are

special special customer-specific components behind doors,

access covers or panels that have hot surfaces and pose a

potential risk, this is also indicated by this pictogram.

2.3. Roof edge protection during transport

(outside installation)

Roofedge transport protection

During transport by truck the units are attached to the

loading surface with tie ropes, pulled across the unit

towards the side edges of the truck.

On external units, to protect the roof edge from distor-

tion by the tie ropes protection plates are added.

For safety reasons these protection plates must be

fixed.This is done by attaching them with self-tapping

screws to the roof edge.

Make sure that the protection plates are removed after

arrival on site before the AHU is lifted.

2.5. Horizontal Transport

For horizontal movement pallet lifters or transport

skids can be placed under the installation frame or

under the lifting bars. It is important that these support

the lifting points. At no time should the cross beams

at the ends of the unit sections be used for jacking or

tracking the AHU. FOR HORIZONTAL TRANSPORT

ALWAYS PROVIDE SUPPORT UNDER THE LIFT-

ING POINTS. The use of bars as rollers can result in

damage to the installation frame.
