B.
Remove the four (4) screws securing the thermostat access panel and
the two (2) thermostat insulation pads, exposing the thermostat. The
plastic personnel protector
should not be removed
.
C.
With a small screwdriver, adjust the thermostat setting. The 120°F fac-
tory set position (the recommended setting) is at the 6 o’clock position
(Refer to Figure 10). The temperature settings range from approximate-
ly 90°F to approximately 150°F.
D.
Replace the two (2) pieces of fiberglass insulation over the thermostat
and attach the thermostat access panel.
E.
Replace the single piece of fiberglass insulation inside the thermostat
access panel cover and snap in position.
NOTE: It is important that the fiberglass insulation is replaced to
maintain the water heater’s high energy efficiency performance.
3. SAFETY CONTROLS —
The water heater is equipped with a combination
Thermostat and High Temperature Limit Switch that is located above the
heating element. If for any reason the water temperature becomes exces-
sively high, the Limit Switch breaks the power circuit to the heating ele-
ment. Once the control opens, it must be reset manually.
The cause of the High Temperature Condition must be investigated
by qualified service personnel and corrective action taken before
placing the water heater in service again.
To reset High Limit Switch,
turn off
power to water heater, remove jacket
access panel and insulation, and the access panel and insulation to
expose the Thermostat and High Limit Switch. (Refer to Figure 9.)
The
plastic personnel protector SHOULD NOT be removed
. Press the
“RESET” button (see Figure 11). Replace insulation and jacket access
panel(s) before turning on power to water heater.
4. EMERGENCY INSTRUCTIONS —
If water heater has been subjected to flood, fire, or physical dam-
age, turn off power and water to water heater. Do not operate the
water heater again until it has been thoroughly checked by quali-
fied service personnel.
5. VACATION AND LONG TIME SHUT-DOWN —
If the water heater is to
remain idle for an extended period of time, the power and water to the
water heater should be turned off to conserve energy. The water heater
and piping should be drained if they might be subjected to freezing temper-
atures.
