Mount Remote Bulb Models For Outdoor
Air Sensing
These models have a 5 ft (1.5 m) capillary that
establishes the maximum distance between the
case and the outdoor mounting.
Install the bulb on the outside of the building in
the shield provided (See Fig. 15) where it can be
exposed to representative air temperature, but not
to direct sunlight. Mount the bulb high enough so
that accumulated snow, leaves, or other debris
cannot obstruct circulation of air around it, and
where children cannot reach it. Avoid vents from
the building.
Install the case at the indoor location selected,
fastening the screws through holes in the back of
the case. Bring out the bulb and tubing through a
3/4 in. (19 mm) hole in the outside wall, avoiding
sharp bends or kinks. Leave excess tubing coiled
near the case. Do not make sharp bends near the
case or bulb.
Slip the bulb through the supports in the shield.
Pinch the split supporting clip until it holds the
bulb firmly in position. If the seal-off tube pro-
trudes from under the shield, bend it under as
shown in Fig. 15.
Hold the shield over the mounting position and
form a smallradius bend in the tubing. Place the
split plug around the tubing and move the shield
into the mounting location as a unit. Push the split
plug into the hole until it is wedged securely in
place. Fasten the shield in place on the wall with
the screws provided.
NOTE: If the tubing is properly shaped and the
split plug installed as directed, the shield
will cover the split plug, and the hole in
the wall will be hidden from sight.
