2.4.1 - Drilling the wall
Installtheunitbydrillingtwoholes(diameterofeither162mmor202mm)inthewallasindicatedinthe
drilling template.
The 202-mm holes will ensure best performance and utmost noiselessness.
• ItispossibletoinstalltheunitUNICOEDGEinsteadofaunitUNICOSKYorUNICOSTARwithout
modifyingthealreadyexistingholes,exceptionmadeforthesmallcondensationdrainhole.
 Inthiscase,inordernottopenalizeperformances,removetheinsulatingmaterialpossiblypresentin

• Drillthewallusingthepropertoolstofacilitateyourjobandpreventexcessdamageordisturbanceto
yourclient.
 Thebesttoolsfordrillinglargeholesinwallsarespecialdrillscalledcoreborerswithveryhightwisting
torqueandadjustablerotatingspeeddependingonthediameteroftheholetobedrilled.
• Topreventthecreationoflargeamountsofdustandrubbleduetodrilling,thecoreborercanbetted
withavacuumsystemappliedbymeansofsuctioncupstothedrillingzone.
• Todrilltheholes,proceedasfollows:
- Placethesupplieddrilljig(M)againstthewallobservingtheminimumdistancesfromtheceiling,
theoorandfromthesidewallsindicatedonthejigitselfwhichcanbekeptinthecorrectposition
usingadhesivetape(Y)(g.4).
- Useasmalldrillorpunchtomark,withextremecare,theexactcentreofeachoftheholestobe
drilled(g.4).
- Usingacoreboringheadmeasuringatleast202mm(or162mm)todrillthetwoholesforentryand
exitoftheair.
Drill the foregoing holes tilted slightly downwards to prevent water from being fed back through
the ducts (g. 5).
Most of the removed material is expelled outwards, therefore make sure that it
does not hit any person or object when it falls out.
In order to avoid as much as possible outer plaster breaking, it is necessary to
proceed carefully with the last part of hole execution, decreasing pressure on
core borers.
