Check once a year for contamination, and if neces-

sary clean with compressed air. Check the connec-

tions in the control box. Check the operation of the

thermostat.

The following warning pictograms are located on the

panel:electrical voltage and hot surface.

Check once a year for contamination and if necessary

clean with compressed air against the direction of the

air flow or clean with a vacuum cleaner. The elimina-

tor assembly after the cooler is removable. Check for

leakage. Check the fins of the droplet eliminator after

the coil. Clean the siphon and check its operation.

Check the condensate pan for contamination and

clean if necessary.

Check the rotor once a year for contamination, and if

necessary clean with compressed air. Check the rotor

speed and compare it with the design data.

Check the operation of the rotation monitor. Depend-

ing on the rotor material the wheel can absorb mois-

ture. When stationary the wheel will become moist on

one side and thus heavier. The rotor speed can be

set to intermittent in the controller so that the wheel

will rotate “x”times per time unit.

The rotor bearings are lubricated for life and do not

require maintenance. The drive motor is accessible

via an inspection cover.

The V-belt is automatically tensioned by a spring-

loaded rocking base on which the motor is installed.

New belts expand a lot in the beginning. Check after

two days if the belt still has enough tension. After this

check the belt tension weekly during the first month

and then check it once a month.

For further operation and maintenance details on the

heat recovery wheel/controller refer to the documenta-

tion provided by the supplier. The following warning

pictogram is located on the panel:rotating parts.

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.

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.

Electrical voltage

This pictogram indicates that there are electrical components

behind this access cover, door or panel that may be dangerous

for the user/installer. Only personnel qualified in accordance

with NEN 3140 is permitted to carry out work on these

components. The pictogram is attached to the access cover

for the electric heater control box.

Removal of transport brackets

This pictogram is located at the bottom of the fan section. It

indicates that the transport brackets must be removed during

commissioning before the fan is started up.

Verwijder transportbeugels voor opstarten ventilator.

Remove transport brackets before starting up the fan.

Retirer les fixations de transport avant démarrage.

Central data

This label contains the data for the AHU, such as order

number, position number etc. If present, the label is normally

located on the access cover or the door of the fan assembly.

Opening the fan door

This pictogram is positioned on the outside of the door or

access cover of the fan assembly. This pictogram warns that

the fan must have been switched off and deenergised for a

minimum of two minutes before the door or access cover is

opened.

Lifting and transport

An instruction is attached to the AHU that describes the

procedures that must be followed for lifting and transport.

The following chapter contains further details.

1.4 - Disposal of parts/materials

- The packaging material must be disposed of in a responsible

manner and in accordance with local regulations.

- Components that are replaced, must be disposed of as

described above.

2 - TRANSPORT AND LIFTING INSTRUCTIONS

2.1 - General

Transport and lifting of the AHU must always be in

accordance with the instructions below. If these instructions

are not observed, irreparable damage may occur to the unit,

and people in the immediate vicinity of the unit are also

endangered. Alarko Carrier does not accept any

responsibility if these instructions are not observed. Transport

and lifting must be carried out by qualified personnel. The

AHU must only be lifted with lifting bars supplied by

Alarko Carrier. Lifting must be carried out in

accordance with local regulations and with the help of

certified lifting aids.

2.2 - Transport and storage

Lifting of the AHU is only permitted under the designated

lifting points. Lifting under the cross beams is prohibited.

This applies to transport as well as storage, and is indicated

on the cross beam with the following label.

! WARNING!

Before opening doors, switch off and deenergise the

fan, and ensure that it has stopped rotating.

(minimum of 2 minutes)

Caution: All doors and access covers must be closed before

starting up the AHU.

Check the plate heat exchanger once a year for con-

tamination and if necessary clean with compressed

air against the direction of the air flow. If dampers are

used, follow the instructions in section 10.6.

Check condensate pan for contamination and clean

if necessary.

Clean the pollutant trap in the steam supply of the

control valve once a year. If a pollutant trap is installed,

clean the condensate drain valve and the inside of

the condensate pan at the same time.

Inspect the control valve, condensate drain and

distribution box twice a year. With steam distribution

pipes in negative pressure systems (air-side) there

may be excess water present, as the condensate may

not drain from the steam distribution pipe. For some

brands a special siphon with a check valve is supplied.

Check the operation of this valve twice a year.

At the periodical checks of the steam humidifier the

casing sections after the humidifier facilitate the

checking of the humidification level. Viewed in the

direction of the air flow there should not be any

steam plume at the end of the steam humidification

section.

The electric humidifier capacity is strongly affected by

contamination of the steam boiler and the electrodes.

This is indicated on the LED. If necessary replace

steam boiler.

For further operation and maintenance details on the

steam humidifier refer to the documentation provided

by the supplier.
