Removing The Cover; Draining The Heater; Removing A Heating Element; Descaling The Heating Element - HTP Everlast 18 Manual De Uso Y Mantenimiento

The water heater has minimal required maintenance procedures. To ensure maximum performance of the water
heater and reduce the risk of a water leak:
• Periodic inspections and tests are always recommended for signs of damage or failure. Any damage,
cracks, leakage, or weakness should be addressed and fixed immediately. Do not over-tighten any of the
connections. Over-tightening could cause serious internal damage to the unit.
• Water heated at higher temperatures produces scale buildup much faster than at lower temperatures.
Having manual shut-off/maintenance valves installed on the inlet and outlet of the water heater will allow
access to the unit. It is recommended to flush the unit once a year under normal conditions or once every six
months if the water supply has unusually hard water.
• Clean the pre-filter on the inlet water side once every six months. Wash lightly to remove any debris.
When any form of maintenance is carried out on the water heater or the home's plumbing system that may
introduce air into the pipes, it is crucial to turn the power off to the water heater and purge the air out of the
lines before restoring power to the unit. Follow "Filling the Water Heater", this manual. FAILURE TO DO SO COULD
RESULT IN PERMANENT DAMAGE TO THE HEATING ELEMENT AND VOID YOUR WARRANTY.
A. Removing the Cover
• Remove the four (4) Phillips screws, two (2) from each side of the water heater.
• The cover can be partially removed by gently pulling it from the assembly. Disconnect the wire harness from
the power control knob to fully remove the cover.
B. Draining the Heater
The water heater can be emptied by:
• Siphoning the water out through any lower service valve on the inlet side.
• Keep a hot water faucet open while siphoning the water out.
C. Removing a Heating Element
• Shut off the power supply and drain the water heater.
• Remove the front cover per the instructions above.
• Remove the three (3) Phillips screws securing the control box cover to the assembly. Carefully remove the
cover.
• Remove all of the wire harnesses connected to the control board.
• Disconnect the inlet and outlet plumbing adapters from the water heater.
• Use a pipe wrench to remove the two spacing nuts from the water heater inlet and outlet adapters.
• Remove the four (4) screws connecting the water heating assembly to the water heater cabinet.
• Remove the five (5) screws connecting the wiring terminals to the water heater cabinet.
• Remove the entire water heating assembly.
• Use a screwdriver to remove all of the
screws connecting the wiring to the heating
element being inspected / replaced. See
Figure 10.
• Use a pipe wrench to remove the element
containing cap from the water heating
assembly.
• Remove the heating element.
D. Descaling the Heating Element
Scale deposits can affect the heating capability of the element. Heavy scale can even cause damage to the
element. The element can be descaled either chemically or manually.
• Soak the element in white vinegar or other food grade descaling solution approved for use in potable water
systems.
• Once descaled, rinse well with a fresh water / baking soda solution.
The element can also be descaled manually:
• After the element has dried, use a soft brush (non-metallic to prevent damaging th stainless steel sheath)
on the element.
• Brush the dried minerals off.
Reinstall the element after descaling. Ensure the element gasket is installed and that the element is rewired
correctly.
Ensure the water heater has been refilled with water before restoring power. Failures due to "dry-firing" ARE NOT
covered by warranty.
