b. Inspection.

(1)

Inspect for physical damage.

(2)

Inspect for signs of overheating.

c. Testing.

(1)

Using an accurate thermometer measure the temperature at the remote bulb location.

(2)

Perform continuity checks with ohmmeter as follows: With the thermostat set below the thermometer reading

there should be continuity between the two terminals. With the thermostat set above the thermometer reading there

should be no continuity.

This can be checked at several points by placing the sensing bulb and the thermometer in a warm or cold container of

water. Be sure to allow time for temperature balance of both thermometer and sensing bulb to be reached.

d. Installation.

(1)

Thread the sensing bulb and capillary down through the grommeted hole in the bottom of the control box.

(2)

Secure the thermostat with two screws and lock washers.

(3)

Taking care not to damage the other capillary lines thread the bulb and capillary through the hole in the heat

shield wall.

(4)

Reclamp the capillary line in its original clamps. Install new plastic tie wraps or use electricians tape to

secure the capillary lines together.

(5)

Insert the bulb in the mounting clamp and tighten the retaining screw and nut.

(6)

Check to see that grommets are in place at heat shield wall.

(7)

See figure 4-12 and reinstall the evaporator air housing and screen.

(8)

Install a grommet in the bottom knockout hole in the thermostat.

(9)

See wiring diagram figures 4-5 or 4-6 and tags and connect wire leads.
