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. 26).
■
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 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.
■
In units in oil-proof design or in the design for high extract air humidity (option)
the condensate is drained to the drip tray in the connection module.
–
Join the hose in the connection module to the condensate drain of the plate
heat exchanger. Attach it using a hose clamp.
