 6 • Residen  al Electric Water Heater Use and Care Guide

Review all of the instruc  ons 
before you begin work. 
If you aren’t sure that you 

can safely and properly do this work 
yourself, call your Lowe’s® store to 
arrange for Professional Installa  on 
(you may also call a qualifi ed person 
of your choice, such as a licensed 
plumber or electrician, to have the 
work done).  Improper installa  on can 
damage the water heater, your home 
and other property, and can present 
risks of serious injury or death. 

Check with your local and 
state authori  es for any local 
or state codes that apply to 

your area. In the absence of local and 
state codes, follow Na  onal Fire 
Protec  on Associa  on (NFPA-70) and 
the current edi  ons of the Na  onal 
Electric Code (NEC) and the Interna-

 onal Plumbing Code (IPC). The 

instruc  ons in this manual comply with 
na  onal codes, but the installer is 
responsible for complying with local 
codes. 

Massachuse  s code requires this wa-
ter heater to be installed in accordance 
with Massachuse  s 248-CMR 2.00 and 
248-CMR 5.00: State Plumbing Code. 
Other local and state authori  es may 
have similar requirements or other 
codes applicable to the installa  on of 
this water heater. 

Before you start, be sure you 
have, and know how to use, the 
following tools and supplies: 

•  Plumbing tools and supplies appropriate 

for the type of water pipes in your home

•  Threaded connectors (fi gure 1) for 

the cold and hot water pipes

 

•  For homes plumbed with plas  c 

pipe, use threaded connectors 

suitable for the specifi c type of 
plas  c pipe used: CPVC and PEX 
(cross-linked polyethylene). Do 
not use PVC pipe. 

 

•  For homes with copper pipes, 

you may purchase connector kits 
with compression fi    ngs that 
don’t require soldering (fi gure 1). 
Compression fi    ngs are easier 
to install than soldering copper 
pipes. 

•  Tefl on® tape or pipe joint compound 

approved for potable water 

•  Tools to make the electrical connec-

 ons (for example, screwdrivers, wire 

strippers)

•  Non-Contact circuit tester to check 

for power (fi gure 2)

•  Water Pressure Gauge (see next 

page, fi gure 4)

•  Suitable drain pan (see page 8, fi gure 6)

•  Automa  c leak detec  on and shut-

off  device

•  Pressure Reducing Valve (fi gure 3)

•  Thermal Expansion Tank (see next 

page, fi gure 5)

•  Point-of-use Thermosta  c Mixing 

Valves (see page 8, fi gure 7)

Figure 1 - Flexible connectors use compression 
fi    ngs and do not require soldering.

Figure 2 - Use a non-contact circuit tester to 
insure that the power is off  before you work on 
a circuit.

Figure 3 - Install a Pressure Reducing Valve set to 
50 to 60 PSI.
