Apply sealing compound to the roof frame.

■ 

Release the cable fastening on the below-roof unit frame and carefully insert 

the cable into the unit.

 

Caution 

Danger of damaging the unit: Dropping the cable may damage the 

heating or cooling coil. Put the cable down carefully.

■ 

Screw in the transport eyes into the connection module frame and attach the 

lifting gear.

– 

Heed the minimum length of the lifting ropes (see Fig. 23).

■ 

Transport the below-roof unit to the roof frame using a helicopter or crane.

■ 

Turn the below-roof unit to the desired position.

■ 

Hang the below-roof unit into the roof frame from above.
