
 Thesectionsmustbeplacedonthebaseframeandiftheunitisdeliveredwith100mmlegs, thesections
mustbepositioneddirectlyoppositeeachother.

1. Ensurethattheinternalfactory‐fittedrubbersealingisundamaged
2. Thesectionsarethentobepositioneddirectlyoppositeeachother.Ifthesectionsarebuiltwith
legs,theadjustablefeetcanbeusedtogetthesectionsparallelandatthesameheight.
3. Pressthesections
hardtogethersothattherubberprofilesaresoflatthattheironframesofthe
twosectionsarejoined.Strapswithtensionerasshownbelowaresuitableforpressingthesections
hardtogether.

4. Thesectionsarethentobelockedpermanentlytogetherwiththeblackplastic‐coatedSystemair
Disc‐Locks.TheDisc‐Locksaredeliveredinacartonboxplacedinsidetheunit.PlaceeachDisc‐Lock
overthe2factoryfittedlockingpins.Thediscsandlockingpinsarenotreliableforpullingthe
sectionstogether.Theyareonlysufficientforkeepingthesectionswelltogether,sojust
turneach
discgentlywiththesuppliedAllenkey.Useasequencewhereeachdiscistightenedwithonlyone
clickatatime.Iftheunitisplacedtooclosetoawallwithnospaceleftforthemountingof
SystemairDisc‐Locks,bracketsmustbeplacedinside
theunittokeepthesectionspermanently
