2. Toremovecover,pullgentlyattheseamatthetop.
3. Putthermostatbaseagainstthewallwhereyouplantomountit(Besurewireswillfeedthrough
thewireopeninginthebaseofthethermostat).
4. Marktheplacementofthemountingholes.
5. Setthermostatbaseandcoverawayfromworkingarea.
6. Usinga3/16”drillbit,drillholesintheplacesyouhavemarkedformounting.
7. Useahammertotapsuppliedanchorsinmountingholes.
8. Alignthermostatbasewithmountingholesandfeedthecontrolwiresthroughslitinthermal
intrusionbarrierandintowireopening.
