Failure to disconnect the power from the water heater before
attempting heating element replacement will result in property
damage, severe personal injury, or death due to electric shock.
Step #2
- Run hot water at a faucet in the system. When it runs cold,
shut off the faucet. Then shut off water at the main cold water inlet
or, if possible, valve off the water heater from the system. Drain the
water from the system, or just the water heater if it can be isolated
from the system.
Completely drain the water heater before removing and replacing
a heating element or elements. Failure to do so will result in a
leakage of water and property damage, and could possibly result
in moderate to severe personal injury or death.
Water drained from the water heater may be scalding hot. Take
care to avoid scalding. Wear gloves and safety glasses, and direct
water to a safe drainage location. Failure to comply with this
warning could result in property damage, severe personal injury,
or death.
DO NOT replace heating element with a generic heating element.
Only HTP heating elements are approved for use with this water
heater. Failure to follow this warning will result in premature
product failure and VOID the warranty.
Step #3
- Remove the element with a 1 1/2” socket wrench or
element tool.
Step #4
- Inspect the removed element. Determine whether the
replacement element will need a square or circular gasket and
washer.

Step #5
- Ensure thread and opening are completely free of debris.
Use a nylon brush to clear away any debris.
Step #6
- Put a small amount of NSF approved lubricant and sealant
on the appropriate gasket and/or washer for the installation. Put the
gasket and/or washer on the element.
Step #7
- Screw the element clockwise into the tank, and tighten
with the 1 1/2” socket wrench or element tool. Be sure gasket seats
properly.
Step #8
- Open the main cold water inlet. If the water heater has
been isolated from the system, open the valves. Refill the tank with
cold water. Open a hot water faucet high in the system to bleed
any air pressure from the system. Water will flow freely when air is
completely bled.
When filling the water heater, open a hot water tap to release air in
the tank and piping. The tank must be full of water before the heater
is turned on. Failure to ensure the water heater is full before turning
it on will result in damage to the water heater, and could result in
property damage, serious personal injury, or death. Such damages
ARE NOT covered by water heater warranty.
Step #9
- Pressure check the tank for leaks around element. If no leaks
are found, use a Phillips Head screwdriver to connect the wires to the
element.
Step #10
- Turn power back on to the water heater.
Failure to refill the tank before restoring power to the water heater
will result in damage to the heating elements and property damage.
Such damages ARE NOT covered by warranty.
Part 4 - Service / Maintenance Procedures
A properly maintained solar water heating system can provide years
of dependable, trouble-free service. It is suggested that a routine
preventive maintenance program be established and followed by the
end user with the solar contractor. Listed below is the maintenance
check list that outlines the primary components of the solar system
that need to be inspected annually.
1. HTF Glycol – It is very important that the quality of the glycol
is maintained to avoid damage to the collector loop and related
components. See the manufacturer’s data sheet for further details.
2. Water quality can affect the operation of the solar heat exchanger
over time. In very hard water areas, it is recommended to drain a few
gallons of water from the bottom of the tank to keep the water heater
free of sediment.
3. Clean and inspect the solar collector. Dirt or film may settle on the
surface and affect performance. Check collector supplier for cleaning
procedures.
4. Check piping and component insulation for deterioration.
5. Check solar tank sensors. Assure these sensors are secure and have
not moved or loosened.
6. Inspect the T&P valve on the water heater. Lift the release handle
lever. Make sure discharge is directed to an open drain.
Never open the pressure relief valve while the system is in operation
or hot water is present. Allow to cool prior to opening. Failure to do
so could result in serious personal injury or death.
7. The area near the water heater must be kept free of flammable liquids
such as gasoline, paint thinners, adhesives, or other combustible
materials.
8. The electric element may need cleaning. A hissing sound while
operating indicates the element has built up deposits. Cleaning should
only be done by a qualified plumbing or heating contractor.
If the heating element needs replacement, it is VERY important to use
the same voltage, wattage, and construction. This element must be
stainless steel and the hex plug be made of brass. This replacement
part is available from HTP and should not be purchased from outside
sources.
