SECTION IV
– OPERATION AND MAINTENANCE
Maintenance:
•
The Hubbell TXA series water heater requires periodical maintenance, to check around
the outside and inside of the unit for water leaks. Inspect the contactors for wear, noise
and to also inspect ALL wiring connects for tightness. If a water leak is found in
your water heater, turn off the water supply at the shut-off valve on the inlet side of
the water heater, turn off the power to the heater at the main electrical panel or service
disconnect and call a service technician or plumber for evaluation and repair.
•
Once a year the heating chamber should be flushed to remove any debris or mineral
build up that has accumulated in the operation of the heater. It may be required to run
required to run a descaling solution to help remove built up scale.
•
When any maintenance is performed on the water heater or the plumbing system that
may introduce air into the water supply pipes, it is important to turn the power off to
the water heater and purge the air out of the lines before restoring power to the unit.
See Checking for Leaks and Purging Air in Section III.
First Use of your Hubbell Tankless Water Heater:
Once the water supply is on and air has been purged from the system, power the unit on at the
main panel. The unit is now operating automatically. When water flows through the unit, the
heating elements turn on to heat the water to the displayed setpoint temperature. When the
water flow stops, the heating elements turn off.
You can adjust the setpoint upward or downward by pressing the UP or DOWN button on either
the internal or remote display.
Displaying Celsius or Fahrenheit degrees and adjusting other settings for the tankless water
heater can be done via the configuration menu, described below.
