in the compression fitting, as well as the temperature probe will come out
of the tank with the compression fitting body.
8.
Remove the body of the thermostat from its mounting.
9.
Verify that the new thermostat is rated the same as the thermostat that is
being replaced.
10.
Mount the new thermostat, being careful not to damage the capillary tube
or temperature probe.
11.
Carefully configure (bend) the capillary tube to allow the temperature
probe to be inserted into the tank. In addition, to insure proper positioning
of the probe, straighten the capillary tube in the area where it meets the
temperature probe.
12.
Insert the temperature probe into the tank and start the compression fitting
body into the threads. Follow recommendations contained in the
manufacturer's documentation, local codes, or accepted contractor
practices as to the type and / or use of joint compound or sealer at the
connections.
13.
Tighten the body of the compression fitting with the correct size
wrench
.
A socket can not be used to tighten the fitting because of the attached
capillary tube.
Do not tighten the compression fitting cap nut
.
14.
Gently withdraw any extra length of the capillary tube from the tank,
pulling the temperature probe snug against the inside of the compression
fitting body.
Note: If the temperature probe is not correctly positioned in the tank (i.e.: it is
allowed to droop), it will not correctly sense the water temperature at the
level of the heating elements.
15.
Slide the compression ring into place against the compression fitting body
and tighten the cap nut.
16.
Reconnect the wires to the new thermostat, checking to assure that they
are attached in the same position from which they were removed.
17.
Set the temperature selector (for operating and auxiliary high temperature
limit thermostats only - the high temperature limit thermostat is factory
preset and can not be adjusted). For operating thermostats, the
temperature should be set the same for all. The auxiliary high temperature
