Installing the water heater
The location chosen for the water heater must take into consideration the following:
This water heater must be installed in accordance with these instructions, local codes, utility codes, utility company
requirements or, in the absence of local codes, the latest edition of the National
Local installation regulations
Location
Locate the water heater in a clean dry area as near as practical to the area of greatest heated water demand. Long
uninsulated hot water lines can waste energy and water.
Place the water heater in such a manner that the thermostat and element access panels can be removed to permit
inspection and servicing such as removal of elements or checking controls.
The water heater and water lines should be protected from freezing temperatures. Do not install the water heater in
outdoor, unprotected areas.
It is prohibited to install water heaters in bathrooms, outdoors, or other humid or open environments to prevent
electrical malfunctions.
Inspect the water heater for possible damage. Check the markings on the rating plate of the water heater to be
certain the power supply corresponds to the water heater requirements.

Installing the water heater (cont.)
Determine if a check valve exists in the inlet water line. Check with your local water utility. It may have been installed

inspector for information regarding the control of this situation.
y be part of a pressure reducing valve, water meter
or water softener. A check valve located in the cold water inlet line can cause what is referred to as a “closed water
prevention device is referred to as an “open” water
system.
As water is heated, it expands in volume and creates an increase in the pressure within the water system. This
action is referred to as “thermal expansion”. In an “open” water system, expanding water which exceeds the
the pressure is easily dissipated.
A “closed water system”, however, prevents the expanding water
and the result of “thermal expansion” can create a rapid and dangerous pressure increase in the water heater
and system piping. This rapid pressure increase can quickly reach the safety setting of the relief valve, causing
it to operate during each heating cycle. Thermal expansion, and the resulting rapid and repeated expansion and
contraction of components in the water heater and piping system can cause premature failure of the relief valve,
and possibly the heater itself. Replacing the relief valve will not correct the problem!
The suggested method of controlling thermal expansion is to install an expansion tank in the cold water line
between the water heater and the check valve (refer to the illustration below). The expansion tank is designed
with an air cushion built in that compresses as the system pressure increases, thereby relieving the over pressure
condition and eliminating the repeated operation of the relief valve. Other methods of controlling thermal expansion
are also available. Contact your installing contractor, water supplier or plumbing inspector for additional information
regarding this subject.

combination temperature and pressure relief valve certified by a nationally recognized testing
laboratory that maintains periodic inspection of production of listed equipment or materials, as
meeting the requirements for Relief Valves and Automatic Gas Shutoff Devices for Hot Water Supply
Systems, ANSI Z21.22.This valve must be marked with a maximum set pressure not to exceed the
marked maximum working pressure of the water heater. Install the valve into an opening provided
and marked for this purpose in the water heater, and orient it or provide tubing so that any
discharge from the valve exits only within 6 inches above, or at any distance below, the structural
floor, and does not contact any live electrical part. The discharge opening must not be blocked or
reduced in size under any circumstances.
Relief Valve
DO NOT turn on the electrical supply
or operate this water heater unless it is
completely full of water. The tank must
be full of water before heater is turned
on. The water heater warranty does
not cover damage or failure resulting
from operation with an empty or
partially empty tank.
WARNING!
The Btu/h rating of the relief valve must not be less
than the input rating of the water heater as indicated
on the rating label located on the front of the heater
(1 watt=3.412 Btu/h).
Connect the outlet of the relief valve to a suitable open
drain so that the discharge water cannot contact live
electrical parts or persons and to eliminate potential
water damage.
Piping used should be of a type approved for hot
water distribution. The discharge line must be no
smaller than the outlet of the valve and must pitch
downward from the valve to allow complete drainage
(by gravity) of the relief valve and discharge line. The
end of the discharge line should not be threaded or
concealed and should be protected from freezing.
No valve of any type, restriction or reducer coupling
should be installed in the discharge line.

A water heater’s tank can act as a setting basin for
solids suspended in the water.It is therefore not
uncommon for hard water deposits to accumulate in
the bottom of the tank. It is suggested that a few quarts
of water be drained from the water heater’s tank every
month to clean the tank of these deposits.
Rapid closing of faucets or solenoid valves in automatic
water using appliances can cause a banging noise heard
in a water pipe. Strategically located risers in the water
pipe system or water hammer arresting devices can be
used to minimize the problem.

2. Before Installation – Verify Grounding
Disconnect the breaker and inspect the electrical connections on the old water heater. If damage to the wiring coming from the electrical
panel is apparent, please call a qualified electrician before continuing with the installation. Damage could look like frayed wiring, insulation
degradation, and failed electrical bushings. Once electrical connections are confirmed to be undamaged, disconnect the wiring and remove
the old heater.
3. During Installation:
1. Visual Inspection of Midea Water Heater
o Confirm that the green or bare copper grounding wire is securely connected to the water heater’s ground screw within the
terminal box located on the top pan.
2. Continuity Test
o Connect the wiring from the panel box to the water heater and then using a multimeter, check for electrical continuity
between:
▪ The water heater’s metal jacket (or ground terminal), and the ground terminal screw located on the breaker panel
(e.g., service panel ground bar or grounded outlet box).
o The resistance should be close to 0 ohms. A high resistance indicates a faulty or broken ground. If the ground is broken,
contact a qualified electrician for repair.
3. Ground Loop Impedance Test (if required by local code)
o For professional verification, a loop impedance tester can be used to verify that the ground path has sufficiently low
impedance allowing breakers to safely trip in fault conditions.
3. After Installation – Confirm Connection
• Ensure that all wire terminations are tight and corrosion-free.
• Do not paint over bonding or grounding points.
• Do not energize the unit until grounding is confirmed.
