LOCATION
Proper operation of the regulator is greatly affected by its
location. Installing it in a place with no air circulation or
exposed to direct sunlight can cause improper regulation
of temperature. The regulator should be installed on an
interior wall of a building (partition wall), in an environ-
ment with unobstructed circulation air of air. Avoid heat
radiating devices (television set, heater, refrigerator etc.)
or places exposed to direct sunlight. Direct vicinity of door
can be a source of problems due to the potential of expos-
ing the regulator to vibration.
