Enclosure lid must be properly sealed prior
to operating. Each of the four (4) screws are
to be evenly tightened by hand with appropri-
ate screw driver ONLY until snug. It is recom-
mended that the lid be secured with a torque
of 12-15 inch-lbs per screw. Overtightening or
uneven tightening may cause the lid to break
which would void all environmental and haz-
ardous location approvals. Due to an electrical
shock hazard, do not operate thermostat if lid
is cracked, broken or uneven with enclosure.
Be sure to install this device vertically as pic-
tured. This controller utilizes a heat sink which
is designed to cool the unit during operation.
Under no circumstance should air flow around
the controller be compromised in any way.
Failure to do so may result in the overheating
of the controller, product failure, product tem-
peratures which exceed the Hazardous Area
maximum temperature limit and even fire.
