EU Air Handling Unit MAINTENANCE

Adjustment

The air handling unit must be adjusted before being

taken into service to ensure its satisfactory function.

Since the unit must function reliable year after year,

it must receive proper maintenance and the correct

spare parts.

Adjustment includes the following operations:

Filter – check pressure sensor

Heater – check shunt

Cooler – check shunt, or check valves and compressor

Humidifier – check water quaklity

Fan – check belt tension

Rotary heat exchanger – setting of forced air cleaning

sector and direction of rota-

tion at constant speed

Plate heat exchanger – check damper function

Water trap – check that the water trap is full

This check is not required if water trap EUAZ-08 is

used.

Maintenance

Regular maintenance of this air handling unit can be

provided by signing a contract with an Fläkt Woods

company, or maintenance can be carried out by the

company normally responsible for maintaining the

property.

Inspection intervals

A number of service charts to be completed by the

person who maintains the unit can be found at the rear

of this book.

The service chart includes the service and inspec-

tion operations to be performed on functional compo-

nents that may be part of an air handling unit. The unit

contains one or more of these functional components.

Any components that are not relevant may be deleted

from the service chart.

The chart shall be dated and signed each time serv-

icing is carried out.

The length of the service interval is estimated at 2000

operating hours over a 12-month period and for an

installation providing a normal comfort level.

In environments with a high level of dust in the

supply air or exhaust air, inspection of the air

handling unit shall be performed at more frequent

intervals.

Replacement of door seal

The door seal is available as a spare part and must be

replaced, if necessary, to ensure that the unit is

airtight.

Spare parts

Spare parts and accessories for this unit can be ordered

from our nearest sales office.

The order should also state the product code.

The code can be found on a separate data panel

located on the functional component concerned.
