NOTE: TO PREVENT EXHAUSTING PRODUCTS FROM

CIRCULATING TOTHEAIR INTAKE IN WINDY/COLDAREAS,

THE MAXIMUM PRACTICAL DISTANCE BETWEEN THESE TWO

TERMINALS IS RECOMMENDED.

FIGURE 18C.

WHEN LOCATING THE TERMINALS ON A SIDEWALL, THE

FOLLOWING SPECIFICATIONS PERTAINING TO TERMINAL

LOCATION MUST BE FOLLOWED.
