10. START-UP INSTRUCTIONS

10.1. Casing

The label with the unit data, such as order number,

position number etc. is usually located on the acccess

cover or door of the fan compartment.

Check the AHU panels for any damage. Any dirt or

stains must be removed from the surface to prevent

possible long-term damage. Building debris left on the

roof must be removed. Dirt can be removed with water

and a mild house-hold soap solution. Damage can be

repaired by thoroughly cleaning the affected surface,

then treat and paint as necessary. If applicable check

the sealing joints and repair if required.

Check the operation of door handles, locks and move-

ment of the hinges. For outside installation of the AHU

check the storm cord.

Check that all flexible connections are attached to the

AHU. If necessary, tighten loose screws.

Ensure that the AHU has been earthed correctly and

in accordance with local regulations. A label on the

support frame indicates where the unit should be

earthed.

!CAUTION!

Doors and access covers must always be

closed before starting the unit.

10.6. AHU Installation and Connection

The floor in the room where the AHU is installed

must be water-tight and flat to prevent connection

problems. Before the units are placed against or on

top of each other, the sealing tape supplied must be

attached between the casing sections.

Place the casing sections as close as possible to-

gether before assembly. Pull the casing sections

towards each other by placing the lifting bars first in

one and then in the other casing section. Then pull

both parts towards each other using pull ropes.

The casing sections are connected with the frames

and fixing elements supplied. If the AHU is installed

outside, the roof connecting plate provided must be

installed on the roof and sealed.
