ing temperature, start the actuator motor electrically

or pneumatically and set the desired humidity level.

Refer to the instructions of the supplier.

of the pollution trap and check the condensate drain.

For casings with negative pressure the operation of

the negative pressure system must be controlled with

the check valve.

pipes.

-The condensate drain should not be without pressure

in accordance with the manufacturer’s instructions.

Refer to the instructions of the supplier.

-If the AHU has negative pressure, install a special

siphon ahead of the condensate drain.

draw.

10.12. Heat Recovery Wheel

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.

10.13. Plate Heat Exchanger

-Check if the dampers close correctly.

-Check if the damper can open to the correct position.

-Check operation after the power has been restored

following a power cut. Some dampers must be open,

others must be closed.

-Check if fins have been bent during transport. Correctly

straighten the fins.

-Check if the siphon has been correctly installed. Check

if siphon cover and ball have been correctly installed.
