Installing the roof unit
■
Remove the cover caps on the unit roof.
■
Screw in the transport eyes and attach the lifting gear.
–
Heed the minimum length of the lifting ropes (see Fig. 22).
■
Transport the roof unit onto the roof.
■
Open the supply air access door and the exhaust air access door and position
the roof unit correctly in relation to the below-roof unit, placing the roof unit on
top of the below-roof unit. The centring bolts on the connection module support
the correct positioning.
■
Screw the roof unit to the below-roof unit:
–
To do this, use the supplied M6 x 30 screws.
–
Secure the screw connection using medium-strength, soluble adhesive
(e.g. Loctite 243).
■
Remove the transport eyes and attach the cover caps.
– Keep the transport eyes for when disassembling the units at a later date at
the end of their service life.
■
Reattach the fan protecting plate on the supply air side:
–
Temporarily screw the protecting plate tight using 4 M5 x 16 screws; it must
be removed again for electrical installation later.
Attention
Risk of damage to the unit due to condensation. If the electrical
installation is not carried out until the next day or later and cold weather
is to be expected: Tighten the fan protecting plate with all screws to
prevent condensation.
