(withinsulation),washers(withoutinsulation)andnuts(double).

• Fitthewasherwithcushionsothattheinsulationfacesdownward.

• Incaseofusingupperwasherstosuspendthemainunit,thelowerwashers(with

insulation)andnuts(double)aretobesetlater.

2. Lift the unit to the proper height of the suspension bolts to insert the mounting

plate between washers and then fasten it securely.

3. Whenthemainunitcannotbealignedagainstthemountingholeontheceiling,

itisadjustableowingtoaslotprovidedonthemountingplate.(Fig.4-6)

• MakesurethatstepAisperformedwithin37-42mm(1-15/32to1-21/32inch).

Damage could result by failing to adhere to this range.

4.6. Conrmingthepositionofmainunitandtightening

thesuspensionbolts(Fig.4-7)

• Usingthegaugeattachedtothegrille,ensurethatthebottomofthemainunitis

properlyalignedwiththeopeningoftheceiling.Besuretoconrmthis,otherwise

condensation may form and drip due to air leakage etc.

• Conrmthatthemainunitishorizontallylevelled,usingaleveloravinyltubelled

with water.

• Aftercheckingthepositionofthemainunit,tightenthenutsofthesuspensionbolts

securely to fasten the main unit.

• Theinstallationtemplatecanbeusedasaprotectivesheettopreventdustfrom

entering the main unit when the grilles are left unattached for a while or when the
