6. While the tank is filling, open the electrical
control panel and set the thermostat(s) to the
desired water temperature. If equipped with
multiple thermostats, all individual
thermostats may be adjusted to the same
temperature set point or they may be set a 2°F
to 4°F (1˚C to 2˚C) apart to step the elements
on in stages.
7. Insure that any pilot switches or manual
limiting switches are placed in the
“ON” position.
8. When a constant flow is obtained at the
faucet, it may be turned off. The temperature
and pressure relief valve should be manually
opened to insure that there is no captive air in
the storage tank. A constant stream of water
must flow from the manually opened relief
valve. Release the handle on the relief valve
and allow it to close after water flow is observed.
9. Carefully check the tank, pipe and fittings for
any sign of a water leak. Immediately repair
as needed. Open the access door to the
immersion heating elements and check for
leaks at the element mounting flanges. If any
leak is detected, tighten the screw–in element.
10. Insure that the electrical access panel (field
wiring compartment) is closed and the
heating element access panel is in place
before proceeding.
11. After assuring that the tank is completely
filled with water and no leaks are detected,
you are now ready to start operation of the
water heater.
12. Turn on the electric power at the main
disconnect point. The contactors should be
energized as the elements start to heat the
water in the tank.

START-UP
13. As the water heater starts heating, check the
contactors for “buzzing” or “chattering”
during operation. If noise is detected, turn off
main power, open the control panel and clean
the contact points of the magnetic
contactor(s). Remove any dust, dirt or foreign
matter that may have found its way into the
contactor or other electrical components in
the control panel during shipping, installation
or service.
14. Close the electrical control panel and turn on
main power.
15. The water heater is now ready for normal
operation.
The following checks should be made by the
installer when the water heater is placed into
operation for the first time.
1. Allow the water heater to heat for
approximately thirty minutes after following
the filling and start up procedures.
2. Turn off the main electrical power to the
water heater
. If the power disconnect point
is out of sight, lock it in the open (“OFF”)
position and tag to prevent unexpected
application of power.
3. Open the electrical control panel door and
feel each wire connection and fuse clip for
excessive temperature. If any connection is
found to be excessively hot, check the
tightness of the connection. Check all factory
internal wiring connections and the field
made main power connections for tightness.
INITIAL START-UP CHECKS
The power supply must
remain off until the water heater and all
related piping are completely filled with water
to insure that there will not be a possible
problem with heating element burn out.
CAUTION:
HAZARD OF ELECTRICAL SHOCK –
Before opening the access panel to perform
service on any electrical component, make
sure the electrical supply to the water
heater is turned “OFF”. Failure to do this
could result in death, serious bodily injury
or property damage.
