FAILURE TO TURN THERMOSTAT OFF BEFORE

DAMAGE DUE TO RAPID COMPRESSOR CY-
CLING.
To attach thermostat to subbase, line up the plastic snap
guides at the bottom of the thermostat and the three
connector pins on the thermostat with the connectors
near the bottom left section of the subbase (when viewed
from the front). Gently pivot the thermostat up until the six
pin connectors and the plastic snaps lock into place (see
fig. 12). Be gentle when attaching thermostat. If the
thermostat does not seem to be attaching to the subbase
easily, make sure that the connector pins and plastic
snaps are properly aligned, and that excess wire is
pushed into the wall. Damage to the thermostat may
occur if force is used.
