B
Mount Thermostat in location where mounting screws
are readily accessible, setpoint knob easily reached,
and scale visible; preferably from top of unit through
access hatch or from front of unit when front panel
is removed.
C
Locate air connections in accessible area. If necessary,
add 1/4-in. plastic elbow and/or tubing extensions to
barb connectors before installation.
D
Mount bulb at either Point E (Fig. 3). Avoid kinks, dents,
or sharp bends in the 36-in. (914 mm) capillary and
mount so that capillary does not rub on sharp corners.
E
Locate plastic tubes away from hot supply lines.
Mounting Procedures
A
Hold Thermostat in place and mark screw hole centers
(Fig. 4). Punch or drill pilot holes for sheet metal screws.
Alternately, Tinnerman nuts can be used by making
clearance holes for the screws.
