Installation instructions
Piggyback units supplied with top and bottom units separated must be securely connected
on site (after the units have been positioned) and sealed tight on the whole perimeter
against rainwater penetration by means of a permanently elastic seal (weatherproof
version KGW).
Units are secured by means of fixing elements and Self-drilling/tapping screw 5,5x19
on the outside, as shown (on site).
The requisite number of fixing elements is supplied with the air-handling unit.
Only secure the top and bottom units together after the individual cubes unit and the
top and bottom units have been assembled.
If required, install permanently resilient sealing strips or plastic sealing profiles before
lowering the top unit into position on the bottom unit.
